A. G. CARRICK / H.M KING CHARLES III former PRINCE OF WALES (bn.1948)
Ben Avon (1,171m - 3,842ft) near Braemar
  United Kingdom (Scotland)

The mountain  
Ben Avon (1,171m - 3,842ft), named in Scottish Gaelic -  Beinn Athfhinn -  which means Hill of the bright one is a mountain in the Cairngorm mountains range of Scotland Eastern Highlands.  The highest point of the massif, known as Leabaidh an Dаimh Bhuidhe (bed of the yellow stag) is classified as both a Munro and a Marilyn. Ben Avon is a very large and complex mountain sprawling over more than 30 km2. The summit plateau is dominated by granite tors, one of which forms the summit. From the broad summit plateau ridges lead in almost every direction, allowing access from Glen Avon to the north, from Beinn a' Bhщird to the west and from Gleann an t-Slugain in the south. To the west of the summit lies the massive corrie, Slochd Mтr, with its rocky cliffs, and the approaches from the south and west take you close to the corrie rim.
The most common ascent route is via the path in the deep glen that separates Ben Avon and Beinn a' Bhщird, or from Beinn a' Bhщird itself. The summit tor itself must be climbed in order to "bag" the mountain, though it is an easy scramble.

The painter
Arthur George Carrick is actually H.M. the King Charles III, former Prince of Wales.
When he began showing his paintings, he was too nervous to display his name so displayed under a pseudonym. Arthur George are two of his names (Charles Phillip Arthur George) and one of his titles is Earl of Carrick. King Charles III is an experienced watercolourist.  He has been painting for most of his adult life, during holidays or when his official diary allows. King Charles' interest began during the 1970s and 1980s when he was inspired by Robert Waddell, who had been his art master at Gordonstoun in Scotland. In time, King Charles met leading artists such as Edward Seago, with whom he discussed watercolour technique, and received further tuition from John Ward, Bryan Organ and Derek Hill.
The Royal Family has a tradition of drawing and painting, and King Charles’ work first came to public notice at a 1977 exhibition at Windsor Castle at which other Royal artists included Queen Victoria, The Duke of Edinburgh and The Duke of York.
King Charles paints in the open air, often finishing a picture in one go and his favourite locations include The Queen's estate at Balmoral in Scotland and Sandringham House in Norfolk, England. Sometimes King Charles  III paints during his skiing holidays, and during overseas tours when possible.
The copyright of King Charles' watercolours belongs to A. G. Carrick Ltd, a trading arm of The King's Charities Foundation. Over the years King Charles III has agreed to exhibitions of his watercolours and of lithographs made from them, on the understanding that any income they generate goes to The Prince of Wales's Charitable Foundation.
Money from the sale of the lithographs also goes to the Foundation but the paintings themselves are never for sale.
In the 1980s King Charles III, then Prince of Wales,  began inviting young British artists to accompany him on official tours overseas and record their impressions, a tradition that has continued to this day.

CAP SPARTEL PAINTED BY EUGENE DELACROIX


EUGENE  DELACROIX (1798-1863)
Cap Spartel (315 m - 1, 050 ft) 
Morocco


In View of Tangier from the seashore, Oil on canvas, Private Collection  


The mountain 
Cap Spartel (315 m - 1, 050 ft) or Ras Spartel (in Arabic: رأس سبارتيل) is a promontory of the coast of Morocco, located at the southern entrance of the Strait of Gibraltar, 14 kilometers west of Tangier. Facing Cape Spartel, 44 km to the north, Cape Trafalgar marks the northern entrance to the strait on the Spanish coast. Cape Spartel is often mistakenly indicated as the northernmost point of Africa.
The promontory benefits from a strong rainfall favorable to the vegetation. In ancient times Cape Spartel was called Cape Ampelusium, or Cap of Vineyards.  Under the promontory, the waves of the Atlantic Ocean have dug caves, where the inhabitants of the region used to carve millstones. Today, these spectacular "Hercules caves" are a tourist attraction.
On Cape Spartel, 110 meters above sea level, there is a lighthouse, which began operating on October 15, 1864. Its construction was ordered by Sultan Mohammed IV ben Abderrahman at the request of the consular representatives of the European powers alarmed by the Many shipwrecks occurring off the coast. The light from the lighthouse is visible 30 nautical miles (55.6 km).
Off Cape Spartel is the Spartel Bank, a shoal, some of which wanted to make the legendary island of Atlantis.

The painter 
Ferdinand Victor Eugène Delacroix was a French Romantic artist regarded from the outset of his career as the leader of the French Romantic school. As a painter and muralist, Delacroix's use of expressive brushstrokes and his study of the optical effects of colour profoundly shaped the work of the Impressionists, while his passion for the exotic inspired the artists of the Symbolist movement. A fine lithographer, Delacroix illustrated various works of William Shakespeare, the Scottish author Walter Scott and the German author Johann Wolfgang von Goethe.
In contrast to the Neoclassical perfectionism of his chief rival Ingres, Delacroix took for his inspiration the art of Rubens and painters of the Venetian Renaissance, with an attendant emphasis on colour and movement rather than clarity of outline and carefully modelled form. Dramatic and romantic content characterized the central themes of his maturity, and led him not to the classical models of Greek and Roman art, but to travel in North Africa, in search of the exotic. Friend and spiritual heir to Théodore Géricault, Delacroix was also inspired by Lord Byron, with whom he shared a strong identification with the "forces of the sublime", of nature in often violent action.

However, Delacroix was given to neither sentimentality nor bombast, and his Romanticism was that of an individualist. In the words of Baudelaire, "Delacroix was passionately in love with passion, but coldly determined to express passion as clearly as possible."
In 1832, Delacroix traveled to Spain and North Africa, as part of a diplomatic mission to Morocco shortly after the French conquered Algeria. He went not primarily to study art, but to escape from the civilization of Paris, in hopes of seeing a more primitive culture.  He eventually produced over 100 paintings and drawings of scenes from or based on the life of the people of North Africa, and added a new and personal chapter to the interest in Orientalism.  Delacroix was entranced by the people and the costumes, and the trip would inform the subject matter of a great many of his future paintings. He believed that the North Africans, in their attire and their attitudes, provided a visual equivalent to the people of Classical Rome and Greece: "The Greeks and Romans are here at my door, in the Arabs who wrap themselves in a white blanket and look like Cato or Brutus…"
He managed to sketch some women secretly in Algiers, as in the painting Women of Algiers in their Apartment (1834), but generally he encountered difficulty in finding Muslim women to pose for him because of Muslim rules requiring that women be covered. Less problematic was the painting of Jewish women in North Africa, as subjects for the Jewish Wedding in Morocco (1837–41).
While in Tangier, Delacroix made many sketches of the people and the city (see painting above), subjects to which he would return until the end of his life. Animals—the embodiment of romantic passion—were incorporated into paintings such as Arab Horses Fighting in a Stable (1860), The Lion Hunt (of which there exist many versions, painted between 1856 and 1861), and Arab Saddling his Horse (1855).

BOÖSAULE MONTES AND PELE IMAGED BY NASA VOYAGER 1

NASA comment for images
Image 1 :  " The eruption of Pele on Jupiter's moon Io. The volcanic plume rises 300 kilometers above the surface in an umbrella-like shape. The plume fallout covers an area the size of Alaska. The vent is a dark spot just north of the triangular-shaped plateau (right center). To the left, the surface is covered by colorful lava flows rich in sulfur. "
Image 2  :  detail from image 1: Boösaule Montes on the left side of image

The mountain
Boösaule Montes (17, 500 m or 17, 5 km - 57, 4147 ft or 10, 9 miles)  is the highest mountain of Jupiter's moon Io, and one of the tallest mountains in the Solar System. It is located in the north-west from the volcano Pele ( on right in the first image), in the mountain range Boösaule.
The highest (southern) peak of the Boösaule Montes, which is the highest peak on Io, as imaged by Voyager 1. North is to the upper left. This image was created from PIA00323 by cropping and sharpening. NASA's description of the uncropped image is as follows:
The official name of the mountain range was given in honor of the cave in Egypt where Io gave birth to Epaphus, and approved by the IAU in 1985.
Mountains are widely distributed across the surface of Io, the innermost large moon of Jupiter. There are about 115 named mountains; the average length is 157 km (98 mi) and the average height is 6,300 m (20,700 ft). The longest is 570 km (350 mi), and the highest is Boцsaule Montes, at 17,500 metres (57,400 ft), taller than any mountain on Earth. Ionian mountains often appear as large, isolated structures; no global tectonic pattern is evident, unlike on Earth, where plate tectonics is dominant.
Io is exceptional for the strong tidal heating it undergoes, caused by the eccentricity of its orbit (which results from its resonance with Europa and Ganymede) in conjunction with the proximity and great mass of Jupiter. This leads to widespread and intensive volcanism. Most volcanoes on Io have little relief; those that can be considered mountains are generally smaller than the mountains formed by tectonic processes, averaging only 1,000 to 2,000 metres (3,300 to 6,600 ft) in height and 40 to 60 kilometres (25 to 37 mi) in width. Several geodynamic models of Io exist but the tectonic mountain-building process is still obscure and debatable. However, it is thought to be related to stresses caused by the rapid volcanic resurfacing of the body.
To explore the origin of Io's mountains, classification of morphological types and description of morphological features are necessary. Five morphological types of mountains have been identified.
- Mesa: a mountain with flat top and relatively smooth surface. It may be difficult to distinguish mesas from eroded layered plains. Ethiopia Planum is a good example of this morphological type.
1 mountains on Io are classified as mesas.
- Plateau : an elevated plain with a rugged surface. There is no steep or prominent peak on plateau. Iopolis Planum is a good example of this type. About 46% of Ionian mountains belong to this morphological type.
- Ridge: an elevated structure dominated by one or more linear or arcuate rises. 28 mountains on Io (or 24%) have been cataloged into this type.
- Massif: an elevated structure dominated by rugged or complex surface and has one or more peaks. Boösaule Montes and Tohil Mons are good examples.

The imager 
The Voyager program is a continuing American scientific program that employs two robotic probes, Voyager 1 and Voyager 2, to study the outer Solar System. They were launched in 1977 to take advantage of a favorable alignment of Jupiter, Saturn, Uranus, and Neptune, and are now exploring the outer boundary of the heliosphere in interstellar space. Although their original mission was to study only the planetary systems of Jupiter and Saturn, Voyager 2 continued on to Uranus and Neptune, and both Voyagers are now tasked with exploring interstellar space. Their mission has been extended three times, and both probes continue to collect and relay useful scientific data. Neither Uranus nor Neptune has been visited by any probe other than Voyager 2.
On August 25, 2012, data from Voyager 1 indicated that it had become the first human-made object to enter interstellar space, traveling "further than anyone, or anything, in history".
As of 2013, Voyager 1 was moving with a velocity of 17 kilometers per second (11 mi/s) relative to the Sun. Voyager 2 is expected to enter interstellar space by 2016, and its plasma spectrometer should provide the first direct measurements of the density and temperature of the interstellar plasma.
Data and photographs collected by the Voyagers' cameras, magnetometers, and other instruments revealed previously unknown details about each of the giant planets and their moons. Close-up images from the spacecraft charted Jupiter’s complex cloud forms, winds, and storm systems and discovered volcanic activity on its moon Io. Saturn’s rings were found to have enigmatic braids, kinks, and spokes and to be accompanied by a myriad of "ringlets." At Uranus Voyager 2 discovered a substantial magnetic field around the planet and 10 additional moons. Its flyby of Neptune uncovered three complete rings and six hitherto unknown moons as well as a planetary magnetic field and complex, widely distributed auroras. Voyager 2 is still the only spacecraft to have visited the ice giants.
The Voyager spacecrafts were built at the Jet Propulsion Laboratory in Southern California, and they were funded by the National Aeronautics and Space Administration (NASA), which also funded their launchings from Cape Canaveral, Florida, their tracking, and everything else concerning the space probes due the radioactive materials on board the spacecraft.

NANGA PARBAT SKETCHED BY COL. GEOFFREY STRAHAN


COLONEL GEOFFREY STRAHAN (1839-1916)
Nanga Parbat (8,126 m - 26,660 ft) 
 Pakistan

In  Nanga Parbat seen in the distance through the Kashmir Valley, 1885, watercolour

The mountain 
Nanga Parbat  (8,126 m - 26,660 ft) , literally Naked Mountain, is the ninth highest mountain in the world above sea level and  one of the eight-thousanders.  Nanga Parbat forms the western anchor of the Himalayan Range and is the westernmost eight-thousander. It lies just south of the Indus River in the Diamer District of Gilgit–Baltistan in Pakistan. Not far to the north is the western end of the Karakoram range.
To the south, Nanga Parbat boasts what is often referred to as the highest mountain face in the world: the Rupal Face rises 4,600 m -15,090 ft  above its base. To the north, the complex, somewhat more gently sloped Rakhiot Flank rises 7,000 m - 22,966 ft from the Indus River valley to the summit in just 25 km (16 mi), one of the 10 greatest elevation gains in so short a distance on Earth.
Nanga Parbat is one of only two peaks on Earth that rank in the top twenty of both the highest mountains in the world, and the most prominent peaks in the world, ranking ninth and fourteenth respectively. The other is Mount Everest, which is first on both lists. It is also the second most prominent peak of the Himalayas, after Mount Everest. The key col for Nanga Parbat is Zoji La in Kashmir, which connects it to higher peaks in the remaining Himalaya-Karakoram range.
Nanga Parbat along with Namcha Barwa on the Tibetan Plateau mark the west and east ends of the Himalayas.
Climbing 
Steeped in a history matched by few others in Asia it has staged some of the greatest Himalayan ascents of all time. From Hermann Buhl’s solo first ascent in 1953 via the Upper North ridge to Gunther and Reinhold Messner’s first ascent of the Rupal Face in 1970 via the South South East Spur, Messner’s solo climb of the Diamir Face in 1978, and more recently Vince Anderson and Steve House’s Alpine-style ascent of the Central Pillar of the Rupal Face. These epic climbs continue to inspire climbers to attempt yearly what is considered to be the second hardest 8000m mountain after K2. Nanga Parbat is a truly awesome spectacle. The south face is the largest in the world extending over four kilometres above base camp. To date there have only been five ascents from the south.  The north face is equally intimidating. In contrast to the south face’s steep rock and ice the snowy north face is guarded by a broad barrier of seracs that extend the width of the mountain. Climbers before the Second World War were convinced that the only way to climb the mountain was from the north via a long arc extending over Rakhiot Peak, between the two summits of Silberzacken and finally to the summit of Nanga Parbat thereby avoiding a more direct ascent of the north face. The route was dangerously prone to avalanche and exposed to bad weather. 31 people died attempting to climb the mountain leading to it acquiring the infamous name of the “Killer Mountain”. Nowadays it is not such a killer and there are other peaks that could inherit the nickname (eg Ultar or Batura I). Hermann Buhl’s summit route has only been repeated once (Slovak, 1971) to this day. His ascent marked only the third 8000m ascent after Annapurna I (1950) and Everest and was the only first summit of all the 8000ers to be done without oxygen and of course solo. Most attempts nowadays are via the Westerly Diamir face which is generally considered to be the easiest and safest with the Kinshofer Route the normal route. Nanga Parbat as of 2005, had received 263 ascents by 261 individuals (Messner and SP Member Qudrat Ali have climbed it twice) at a price of 62 deaths. Sixteen women have summited the mountain. Numerous challenging lines still await. The most difficult is an ascent of Nanga Parbat via the unclimbed Mazeno Ridge which constitutes the longest ridge in the world. A number of expeditions have made ‘attempts’ on the mountain during winter but to no avail.

MONT GAUSSIER PAINTED BY VINCENT VAN GOGH


VINCENT VAN GOGH  (1853-1890) 
Le Mont Gaussier (306 m -1,004 ft)  
France

In Le mas St Paul à Saint-Rémy de Provence, 1889, Kroller-Muller Museum, Netherlands

The mountain 
The Mont Gaussier (306 m -1,004 ft) is a summit of the Alpilles located south of the city of Saint-Rémy-de-Provence, France. Today, the place of passage of many hikers who cross it by the GR6, Mount Gaussier was very early used as habitat by protohistoric populations, before having at its summit a medieval castle, nowadays disappeared. Mount Gaussier is made of crystalline limestone, white and hard. One finds in the soil the trace of many fossils. This type of summit is characteristic of the Alpilles range of mountains, especially on the north face.
The first traces of habitation on Mount Gaussier are ancient. In 1996,  three sites dating from Protohistory and Late Antiquity were discovered at the summit and on the slopes. This is what emerges from the study of stones, tiles, ceramics and shards of amphora found on the premises. Moreover, the foundation of a wall was identified at the top during the same prospecting.
Most of the human activity of antiquity at Mount Gaussier nevertheless concentrated at the foot of it, since it was there that was built the Salyan city of Glanum (today Saint-Remy de Provence). Research carried out in 1996 and 1997 revealed that the well-preserved remains of a protohistoric rampart with towers have been cleared in several places, particularly on the ridges which dominate to the north-east and south-west the Saint- Clerg and at the foot of Mount Gaussier. The system of rampart which encircled the city in the 1st and 2nd centuries BC. J.-C. leaned on the cliffs of the mount Gaussier which border it on a hundred meters. It is also believed that Mount Gaussier, by its situation, could be used as an acropolis because of its plateau surrounded by cliffs and that its access from Glanum was made possible by a narrow corridor.
If, according to the archaeologist Henri Rolland, some families occupied the Alpilles range, on the slopes of Mount Gaussier, between the first Iron Age and the end of Antiquity, but also in the High Middle Ages, only the foot and the summit of the mountain were occupied in the following centuries, especially in the 5th and 6th centuries. It was here that a part of the inhabitants of Glanum took up residence after the ruin of the ancient city in the alluvial deposits of the mountain.
Mount Gaussier, like Glanum, then in ruins, and Saint-Remy-de-Provence, became property of the church of Avignon at the end of the 9th century in a county of Provence powered by Count Thibert.
It is possible to reach the Mount Gaussier from the ruins of Glanum or from La Caume by the GR6 climbing previously metal ladders.

 The  painter 
Vincent Willem van Gogh was a Dutch Post-Impressionist painter who is among the most famous and influential figures in the history of Western art. In just over a decade he created about 2100 artworks, including around 860 oil paintings, most of them in the last two years of his life. They include landscapes, still lifes, portraits and self-portraits, and are characterized by bold, symbolic colours, and dramatic, impulsive and expressive brushwork that contributed to the foundations of modern art. He died by suicide at 37, following years of mental illness and poverty.
Born into an upper-middle-class family, Van Gogh drew as a child and was serious, quiet and thoughtful. As a young man he worked as an art dealer, often travelling, but became depressed after he was transferred to London. He turned to religion, and spent time as a missionary in southern Belgium. Later he drifted in ill health and solitude. He took up painting in 1881 having moved back home with his parents. His younger brother Theo supported him financially, and the two kept up a long correspondence by letter.
Van Gogh's early works, mostly still lifes and depictions of peasant labourers, contain few signs of the vivid colour that distinguished his later work. In 1886 he moved to Paris where me met members of the avant-garde, including Emile Bernard and Paul Gauguin, who were reacting against the Impressionist sensibility. As his work developed he created a new approach to still lifes and local landscapes. His paintings grew brighter in colour as he developed a style that became fully realised during his stay in Arles in the south of France in 1888. He lived there in the Yellow House and, with Gauguin, developed a concept of colour that symbolised inner emotion. During this period he broadened his subject matter to include olive trees, cypresses, wheat fields and sunflowers.
Van Gogh suffered from psychotic episodes and delusions and, though he worried about his mental stability, he often neglected his physical health, not eating properly and drinking heavily. His friendship with Gauguin came to an end after he threatened the Frenchman with a razor, and in a rage, cut off part of his own left ear. His stay in a psychiatric hospital in Saint-Rémy led to one of the more productive periods of his life. He discharged himself and moved to the Auberge Ravoux in Auvers-sur-Oise near Paris under the care of the homeopathic doctor and artist, Paul Gachet. On 27 July 1890, Van Gogh shot himself in the chest with a revolver. He died from his injuries two days later.
He sold only one painting during his lifetime, and was considered a madman and a failure. He became famous after his suicide. Van Gogh exists in the public imagination as the quintessential misunderstood genius, the artist "where discourses on madness and creativity converge". His reputation began to grow in the early 20th century as elements of his painting style came to be incorporated by the Fauves and German Expressionists. He attained widespread critical, commercial and popular success over the ensuing decades, and is remembered as an important but tragic painter, whose troubled personality typifies the romantic ideal of the tortured artist.
Van Gogh and Saint Remy de Provence
Van Gogh entered the Saint-Paul-de-Mausole  asylum  in Saint-Rémy de Provence on 8 May 1889, accompanied by his carer, Frédéric Salles, a Protestant clergyman. Saint-Paul was a former monastery in Saint-Rémy, less than 30 kilometres (19 mi) from Arles, and was run by a former naval doctor, Théophile Peyron. Van Gogh had two cells with barred windows, one of which was to be used as a studio. During his stay, the clinic and its garden became the main subjects of his paintings. He made several studies of the hospital's interiors, such as Vestibule of the Asylum and Saint-Rémy (September 1889). Some of his works from this time are characterised by swirls, such as The Starry Night. He was allowed short supervised walks, which led to paintings of cypresses and olive trees, including Olive Trees with the Alpilles in the Background 1889, Cypresses 1889, Cornfield with Cypresses (1889),  Mont Gaussier  and Mas St Paul (1889), Country road in Provence by Night (1890). In September 1889 he produced two further versions of Bedroom in Arles.
Limited access to life outside the clinic resulted in a shortage of subject matter. Van Gogh was left to work on interpretations of other artist's paintings, such as Millet's The Sower and Noon – Rest from Work (after Millet), as well as variations on his own earlier work. Van Gogh was an admirer of the Realism of Jules Breton, Gustave Courbet and Millet, and he compared his copies to a musician's interpreting Beethoven.
Albert Aurier praised his work in the Mercure de France in January 1890, and described him as "a genius". In February Van Gogh painted five versions of L'Arlésienne (Madame Ginoux), based on a charcoal sketch Gauguin had produced when she sat for both artists in November 1888. Also in February, Van Gogh was invited by Les XX, a society of avant-garde painters in Brussels, to participate in their annual exhibition. At the opening dinner a Les XX member, Henry de Groux, insulted Van Gogh's work. Toulouse-Lautrec demanded satisfaction, and Signac declared he would continue to fight for Van Gogh's honour if Lautrec surrendered. De Groux apologised for the slight and left the group. Later, while Van Gogh's exhibit was on display with the Artistes Indйpendants in Paris, Claude Monet said that his work was the best in the show.  After the birth of his nephew, Van Gogh wrote "I started right away to make a picture for him, to hang in their bedroom, branches of white almond blossom against a blue sky."

EL PICHINCHA BY FREDERIC EDWIN CHURCH


FREDERIC EDWIN CHURCH (1826-1900) 
Pichincha (4,784m - 15,696 ft)
Ecuador

 In The Andes of Ecuador, 1855, oil on canvas,  Philadelphia Museum of Art, Pennsylvania

The mountain 
Pichincha is an active stratovolcano in Ecuador, whose capital Quito wraps around its eastern slopes. The two highest peaks of the mountain are Guagua Pichincha (4,784 m -15,696 ft) and Rucu Pichincha (4,698 m - 15,413 ft). The active caldera is in Guagua Pichincha on the western side of the mountain. Both peaks are visible from the city of Quito and both are popular acclimatization climbs. Guagua Pichincha is usually accessed from the village of Lloa outside of Quito. In October 1999, the volcano erupted and covered the city with several inches of ash. Prior to that, the last major eruptions were in 1553  and in 1660, when about 30 cm of ash fell on the city.
The province in which it is located takes its name from the mountain, as is the case for many of the other provinces in Ecuador (Cotopaxi, Chimborazo, Imbabura...). On May 24, 1822, General Sucre southern campaign in the context of the Spanish-America war of independence, came to a climax when patriot forces defeated the Spanish colonial army on the south-east slopes of this volcano. The engagement, known as the Battle of Pichincha, secured the independence of the territories of present-day Ecuador.


The painter
Frederic Edwin Church was an American landscape painter born in Hartford, Connecticut. He was a central figure in the Hudson River School of American landscape painters, perhaps best known for painting large panoramic landscapes, often depicting mountains, waterfalls, and sunsets, but also sometimes depicting dramatic natural phenomena that he saw during his travels to the Arctic and Central and South America. Church's paintings put an emphasis on light and a romantic respect for natural detail. In his later years, Church painted classical Mediterranean and Middle Eastern scenes and cityscapes.
Church was the product of the second generation of the Hudson River School and the pupil of Thomas Cole, the school’s founder. The Hudson River School was established by the British Thomas Cole when he moved to America and started painting landscapes, mostly of mountains and other traditional American scenes.  Both Cole and Church were devout Protestants and the latter's beliefs played a role in his paintings especially his early canvases.  Church did differ from Cole in the topics of his paintings: he preferred natural and often majestic scenes over Cole's propensity towards allegory.
Church, like most second generation Hudson River School painters, used extraordinary detail, romanticism, and luminism in his paintings. Romanticism was prominent in Britain and France in the early 1800s as a counter-movement to the Enlightenment virtues of order and logic. Artists of the Romantic period often depicted nature in idealized scenes that depicted the richness and beauty of nature, sometimes also with emphasis on the grand scale of nature.
This tradition carries on in the works of Frederic Church, who idealizes an uninterrupted nature, highlighted by creating excruciatingly detailed art. The emphasis on nature is encouraged by the low horizontal lines, and preponderance of sky to enhance the wilderness; humanity, if it is represented, is depicted as small in comparison with the greater natural reality. The technical skill comes in the form of luminism, a Hudson River School innovation particularly present in Church's works. Luminism is also cited as encompassing several technical aspects, which can be seen in Church’s works. One example is the attempt to “hide brushstrokes,” which makes the scene seem more realistic and lessen the artist’s presence in the work. Most importantly is the emphasis on light (hence luminism) in these scenes. The several sources of light create contrast in the pictures that highlights the beauty and detailed imagery in the painting.

KANGCHENJUNGA PAINTED BY NICHOLAS ROERICH


http://wanderingvertexes.blogspot.com


http://wanderingvertexes.blogspot.com

NICHOLAS ROERICH (1874-1947)
Kangchenjunga (8, 538m-28,169 ft) 
India, Népal

Painted in 1933

The mountain 
Kangchenjunga  (8,586 m (28,169 ft) is the  third highest mountain in the world. It  lies partly in Nepal and partly in Sikkim, India. Kangchenjunga is the second highest mountain of the Himalayas after Mount Everest. Three of the five peaks – Main, Central and South – are on the border between North Sikkim and Nepal. Two peaks are in the Taplejung District, Nepal.
Kangchenjunga Main is the highest mountain in India, and the easternmost of the mountains higher than 8,000 m (26,000 ft).  Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations based on various readings and measurements made by the Great Trigonometrical Survey of India in 1849 came to the conclusion that Mount Everest, known as Peak XV at the time, was the highest.  It is listed int the  Eight Thousanders and as Seven Third Summits
Kangchenjunga is the official spelling adopted by Douglas Freshfield, A. M. Kellas, and the Royal Geographical Society that gives the best indication of the Tibetan pronunciation. Freshfield referred to the spelling used by the Indian Government since the late 19th century. There are a number of alternative spellings including Kangchendzцnga, Khangchendzonga, and Kanchenjunga.  Local Lhopo people believe that the treasures are hidden but reveal to the devout when the world is in peril; the treasures comprise salt, gold, turquoise and precious stones, sacred scriptures, invincible armor or ammunition, grain and medicine. Kangchenjunga's name in the Limbu language is Senjelungma or Seseylungma, and is believed to be an abode of the omnipotent goddess Yuma Sammang.
It rises in a section of the Himalayas called Kangchenjunga Himal that is limited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River. It lies about 128 km (80 mi) east of Mount Everest.
Allowing for further verification of all calculations, it was officially announced in 1856 that
Kangchenjunga was first climbed on 25 May 1955 by Joe Brown and George Band, who were part of a British expedition. They stopped short of the summit as per the promise given to the Chogyal that the top of the mountain would remain inviolate. Every climber or climbing group that has reached the summit has followed this tradition. Other members of this expedition included John Angelo Jackson and Tom Mackinon.  In May 1979,  Doug Scott, Peter Boardman and Joe Tasker established a new route on the North Ridge their third ascent which was the first one ever made without oxygen.
In 1983, Pierre Beghin made the first solo ascent accomplished without the use of supplemental oxygen.  In 1992, Wanda Rutkiewicz was  the first woman in the world to ascend and descend K2 and a world-renowned Polish climber, died after she insisted on waiting for an incoming storm to pass, which she did not survive.  In 1998, Ginette Harrison was the first woman who climbed Kangchenjunga North face ;  Gerlinde Kaltenbrunner, an Austrian mountaineer, was the second woman to reach the summit in 2006.
In May 2014, the Bulgarian diabetic climber Boyan Petrov reached the peak without the use of supplemental oxygen.

The painter 
Nicholas Roerich known also as Nikolai Konstantinovich Rerikh (Никола́й Константи́нович Ре́рих) is quite an important figure of mountain paintings in the early 20th century.  He was a Russian painter, writer, archaeologist, theosophist, perceived by some in Russia as an enlightener, philosopher, and public figure. In his youth was he was quite influenced by a movement in Russian society around the occult and was interested in hypnosis and other spiritual practices. His paintings are said to have hypnotic expression.
Born in Saint Petersburg, Russia, he lived in various places around the world until his death in Naggar, Himachal Pradesh, India. Trained as an artist and a lawyer, his main interests were literature, philosophy, archaeology, and especially art. After the February Revolution of 1917 and the end of the czarist regime, Roerich, a political moderate who valued Russia's cultural heritage more than ideology and party politics, had an active part in artistic politics. With Maxim Gorky and Aleksandr Benois, he participated with the so-called "Gorky Commission" and its successor organization, the Arts Union (SDI).
After the October Revolution and the acquisition of power of Lenin's Bolshevik Party, Roerich became increasingly discouraged about Russia's political future. During early 1918, he, Helena, and their two sons George and Sviatoslav emigrated to Finland. After some months in Finland and Scandinavia, the Roerichs relocated to London, arriving in mid-1919. Later, a successful exhibition resulted in an invitation from a director at the Art Institute of Chicago, offering to arrange for Roerich's art to tour the United States. During the autumn of 1920, the Roerichs traveled to America by sea.  The Roerichs remained in the United States from October 1920 until May 1923.
After leaving New York, the Roerichs – together with their son George and six friends – began the five-year-long 'Roerich Asian Expedition' that, in Roerich's own words: "started from Sikkim through Punjab, Kashmir, Ladakh, the Karakoram Mountains, Khotan, Kashgar, Qara Shar, Urumchi, Irtysh, the Altai Mountains, the Oyrot region of Mongolia, the Central Gobi, Kansu, Tsaidam, and Tibet" with a detour through Siberia to Moscow in 1926.
In 1929 Nicholas Roerich was nominated for the Nobel Peace Prize by the University of Paris. He received two more nominations in 1932 and 1935. His concern for peace resulted in his creation of the Pax Cultura, the "Red Cross" of art and culture. His work for this cause also resulted in the United States and the twenty other nations of the Pan-American Union signing the Roerich Pact on April 15, 1935 at the White House. The Roerich Pact is an early international instrument protecting cultural property.
In 1934–1935, the U.S. Department of Agriculture (then headed by Roerich admirer Henry A. Wallace) sponsored an expedition by Roerich and USDA scientists H. G. MacMillan and James F. Stephens to Inner Mongolia, Manchuria, and China.
Roerich was in India during the Second World War, where he painted Russian epic heroic and saintly themes, including: Alexander Nevsky, The Fight of Mstislav...
In 1942, Roerich received Jawaharlal Nehru at his house in Kullu. Together they discussed the fate of the new world: "We spoke about Indian-Russian cultural association, it is time to think about useful and creative cooperation ...”.
Gandhi would later recall about several days spent together with Roerich's family: "That was a memorable visit to a surprising and gifted family where each member was a remarkable figure in himself, with a well-defined range of interests." ..."Roerich himself stays in my memory. He was a man with extensive knowledge and enormous experience, a man with a big heart, deeply influenced by all that he observed". During the visit, "ideas and thoughts about closer cooperation between India and USSR were expressed. Now, after India wins independence, they have got its own real implementation[clarification needed]. And as you know, there are friendly and mutually-understanding relationships today between both our countries".
In 1942, the American-Russian cultural Association (ARCA) was created in New York.
Its active participants were Ernest Hemingway, Rockwell Kent, Charlie Chaplin, Emil Cooper, Serge Koussevitzky, and Valeriy Ivanovich Tereshchenko. The Association's activity was welcomed by scientists like Robert Millikan and Arthur Compton.
Roerich died on December 13, 1947.
Presently, the Nicholas Roerich Museum in New York City is a major institution for Roerich's artistic work. Numerous Roerich societies continue to promote his theosophical teachings worldwide. His paintings can be seen in several museums including the Roerich Department of the State Museum of Oriental Arts in Moscow; the Roerich Museum at the International Centre of the Roerichs in Moscow; the Russian State Museum in Saint Petersburg, Russia; a collection in the Tretyakov Gallery in Moscow; a collection in the Art Museum in Novosibirsk, Russia; an important collection in the National Gallery for Foreign Art in Sofia, Bulgaria; a collection in the Art Museum in Nizhny Novgorod Russia; National Museum of Serbia ; the Roerich Hall Estate in Nagar village in Kullu Valley, India; the Sree Chitra Art Gallery, Thiruvananthapuram, India;[17] in various art museums in India; and a selection featuring several of his larger works in The Latvian National Museum of Art.

THE WATZMANN PAINTED BY CASPAR DAVID FRIEDRICH


CASPAR DAVID FRIEDRICH (1774-1840)  
Watzmann (2,713m - 8,901ft) 
Germany

 In  The Watzmann, oil on canvas 1824-25 , Berlin State Museum 

The mountain 
The Watzmann (2,713m - 8,901ft) is a mountain in the Bavarian Alps south of the village of Berchtesgaden. It is the third highest in Germany, and the highest located entirely on German territory. Three main peaks array on a N-S axis along a ridge on the mountain's taller western half: Hocheck (2,651 m), Mittelspitze (Middle Peak, 2,713 m) and Sьdspitze (South Peak, 2,712 m).
The Watzmann massif also includes the 2,307 m Watzmannfrau (Watzmann Wife, also known as Kleiner Watzmann or Small Watzmann), and the Watzmannkinder (Watzmann Children), five lower peaks in the recess between the main peaks and the Watzmannfrau.
The entire massif lies inside Berchtesgaden National Park.
The Watzmann Glacier is located below the famous east face of the Watzmann in the Watzmann cirque and is surrounded by the Watzmanngrat arête, the Watzmannkindern and the Kleiner Watzmann. The size of the glacier reduced from around 30 hectares (74 acres) in 1820 until it split into a few fields of firn, but between 1965 and 1980 it advanced significantly again and now has an area of 10.1 hectares (25 acres). Above and to the west of the icefield lie the remains of a transport-bomber that crashed in October 1940.
Amongst the other permanent snow and icefields the Eiskapelle ("Ice Chapel") is the best known due to its easy accessibility from St. Bartholomä. The Eiskapelle may well be the lowest lying permanent snowfield in the Alps. Its lower end is only 930 metres high in the upper Eisbach valley and is about an hour's walk from St. Bartholomä on the Königssee. The Eiskapelle is fed by mighty avalanches that slide down from the east face of the Watzmann in spring and accumulate in the angle of the rock face. Sometimes a gate-shaped vault forms in the ice at the point where the Eisbach emerges from the Eiskapelle. Before entering there is an urgent warning sign that others have been killed by falling ice.
In the east face itself is another icefield in the so-called Schöllhorn cirque, called the Schöllhorneis, which is crossed by the Kederbach Way (Kederbacher-Weg). The cirque and icefield are named after the Munich citizen, Christian Schöllhorn, who was the first victim on the east face. On 26 May 1890 he fell at the upper end of the icefield into the randkluft and was fatally injured. Another small nameless snowfield is located several hundred metres below the Mittelspitze also in the east face.

The painter 
Caspar David Friedrich was a 19th-century German Romantic landscape painter, considered as the most important German artist of his generation. He is best known for his mid-period allegorical landscapes which typically feature contemplative figures silhouetted against night skies, morning mists, barren trees or Gothic ruins. His primary interest as an artist was the contemplation of nature, and his often symbolic and anti-classical work seeks to convey a subjective, emotional response to the natural world. Friedrich's paintings characteristically set a human presence in diminished perspective amid expansive landscapes, reducing the figures to a scale that, according to the art historian Christopher John Murray, directs "the viewer's gaze towards their metaphysical dimension".
Friedrich was born in Pomerania, where he began to study art. He studied in Copenhagen until 1798, before settling in Dresden. A disillusionment with materialistic society was giving rise everywhere in Europe. This shift in ideals was often expressed through a reevaluation of the natural world, as artists such as Friedrich, J. M. W. Turner (1775–1851) and John Constable (1776–1837) sought to depict nature as a "divine creation, to be set against the artifice of human civilization".
Friedrich's work brought him renown early in his career, and contemporaries such as the French sculptor David d'Angers (1788–1856) spoke of him as a man who had discovered "the tragedy of landscape". Nevertheless, his work fell from favour during his later years, and he died in obscurity, and in the words of the art historian Philip B. Miller, "half mad". As Germany moved towards modernisation in the late 19th century, a new sense of urgency characterized its art, and Friedrich's contemplative depictions of stillness came to be seen as the products of a bygone age. The early 20th century brought a renewed appreciation of his work, beginning in 1906 with an exhibition of thirty-two of his paintings and sculptures in Berlin. By the 1920s his paintings had been discovered by the Expressionists, and in the 1930s and early 1940s Surrealists and Existentialists frequently drew ideas from his work. The rise of Nazism in the early 1930s again saw a resurgence in Friedrich's popularity, but this was followed by a sharp decline as his paintings were, by association with the Nazi movement, interpreted as having a nationalistic aspect.  It was not until the late 1970s that Friedrich regained his reputation as an icon of the German Romantic movement and a painter of international importance.
Friedrich was a prolific artist who produced more than 500 attributed works. In line with the Romantic ideals of his time, he intended his paintings to function as pure aesthetic statements, so he was cautious that the titles given to his work were not overly descriptive or evocative. It is likely that some of today's more literal titles, such as The Stages of Life, were not given by the artist himself, but were instead adopted during one of the revivals of interest in Friedrich. Complications arise when dating Friedrich's work, in part because he often did not directly name or date his canvases. He kept a carefully detailed notebook on his output, however, which has been used by scholars to tie paintings to their completion dates.

BELUKHA MOUNTAIN PAINTED BY VSEVOLOD BAZHENOV


VSEVOLOD BAZHENOV (1909-1986)
 Belukha Mountain  (4,506 m - 14,783 ft) 
Kazakhstan - Russia border 

  In Spring in Altai Mountains, 1979, oil on canvas, Private collection 

The mountain
Belukha Mountain  (4,506 m - 14,783 ft), Russian: Белуха, lit "whitey",located in the Katun Mountains, is the highest peak of the Altai Mountains in Russia. It is part of the World Heritage Site entitled Golden Mountains of Altai. Belukha is a three-peaked mountain massif that rises along the border of Russia and Kazakhstan, just a few tens of miles north of the point where this border meets with the border of China. There are several small glaciers on the mountain, including Belukha Glacier. Of the two peaks, the eastern peak (4,506 m - 14,784 ft.) is higher than the western peak (4,440 m - 14,567 ft.). Belukha was first climbed in 1914 by the Tronov brothers. Most ascents of the eastern peak follow the same southern route as that taken in the first ascent. Though the Altai is lower in elevation than other Asian mountain groups, it is very remote, and much time and planning are required for its approach. A team of scientists, traveled to this remote glacier in the summer of 2001 to assess the feasibility of studying the glacier and extracting ice cores at the site. A Swiss-Russian team also worked on the glacier in 2001. Research was carried out from 2001 to 2003; glaciological observations were made, and both shallow cores and cores to bedrock were extracted and analyzed (Olivier and others, 2003; Fujita and others, 2004). Based on tritium analysis to date, the deeper cores may contain as much as 3–5,000 years of climatic and environmental records.
Since 2008, one is required to apply for a special border zone permit in order to be allowed into the area (if travelling independently without using an agency). Foreigners should apply for the permit to regional FSB border guard office two months before the planned date.

The painter
Vsevolod Andreevich Bazhenov (Russian: Все́волод Андре́евич Баже́нов) was a Soviet, Russian painter who lived and worked in Leningrad. He was a member of the Leningrad branch of Union of Artists of Russian Federation, and regarded as one of the representatives of the Leningrad school of painting, most famous for his landscape paintings.
In 1962 Bazhenov embarked on a working voyage aboard the ship "Eugene Nikishin", sailing from Leningrad to Vladivostok and around Europe and Asia with stops in ports of Gibraltar, Suez, Singapore and Vietnam. During the course of the voyage, which took him through eleven seas and oceans, and lasted more than three months, Bazhenov created nearly two hundred sketches, paintings and drawings. His nature sketches and direct impressions of the voyage led to larger works, finished later in his Leningrad art studio.
After his return in 1963, about 120 works from this series of sketches and paintings were first exhibited in Leningrad, and following that, in other cities. Among them are the works "Arabian Coast", "Boats at the Sea", "In the Singapore Strait", "Denmark on the horizon", "In the Ha Long Bay", "Dolphins play", "Suez Canal", and others.
 His personal exhibitions were in Leningrad (1963, 1982), and Saint Petersburg (1994, 2009). His paintings are in the Russian State Museum, in art museums and private collections in Russia, Japan, France, England, in the U.S., China, and throughout the world.

PUIG NEULOS PAINTED BY ANDRE DERAIN


ANDRE DERAIN (1880-1954)   
Puig Neulos (1,256m - 4,121ft)
Montagnes à Collioure, 1905 
 National Gallery of Art, Washington DC

The mountain 
The Puig Neulós (1,256m - 4,121ft) (or peak Neulos  or Néoulous) is the highest point  of the Albera Range. Puig Neulós is a Catalan name that has been kept as it is in French. Puig refers to a summit or a mountain rounded, Neulós is analogous to the French "nebulous" or "clouded". There is a mention of the summit in a 1322 text in the Latin form Nebuloso Podio, which has exactly the same meaning.
Puig Neulós marks the border between France and Spain, divided between the towns of Laroque-des-Albères, Sorède in the Pyrenees-Orientales and La Jonquera in the province of Girona (Spain). On the summit, there are some antennas for a digital TV and radio transmitter and there is a paved road on the French side (from el Perthus) restricted to military use. 
Below Puig Neulos, on a line of ridges, is the Roc du Midi, very visible, and on the west  the Fouirous rock southwest exposed outcrop. The summit, as well as most of the southern side of the range is part of the National  Park of Albera Range Natural Reserve.

The painter
André Derain was a French artist, painter, sculptor and co-founder of Fauvism with Henri Matisse.
Derain and Matisse worked together through the summer of 1905 in the Mediterranean village of Collioure;  the painting above  showing Collioure mountains and Mount Puig Neulos in the background is dated precisely from that year. Later that year they displayed their highly innovative paintings at the Salon d'Automne. The vivid, unnatural colors led the critic Louis Vauxcelles to derisively dub their works as les Fauves, or "the wild beasts", marking the start of the Fauvist movement. In March 1906, the noted art dealer Ambroise Vollard sent Derain to London to produce a series of paintings with the city as subject. In 30 paintings (29 of which are still extant), Derain presented a portrait of London that was radically different from anything done by previous painters of the city such as Whistler or Monet. With bold colors and compositions, Derain painted multiple pictures of the Thames and Tower Bridge. These London paintings remain among his most popular work. Art critic T.G Rosenthal: "Not since Monet has anyone made London seem so fresh and yet remain quintessentially English. Some of his views of the Thames use the Pointillist technique of multiple dots, although by this time, because the dots have become much larger, it is rather more simply the separation of colours called Divisionism and it is peculiarly effective in conveying the fragmentation of colour in moving water in sunlight."
In 1907 art dealer Daniel-Henry Kahnweiler purchased Derain's entire studio, granting Derain financial stability. He experimented with stone sculpture and moved to Montmartre to be near his friend Pablo Picasso and other noted artists. 
At Montmartre, Derain began to shift from the brilliant Fauvist palette to more muted tones, showing the influence of Cubism and Paul Cézanne.(According to Gertrude Stein, there is a tradition that Derain discovered and was influenced by African sculpture before the Cubists did.  Derain supplied woodcuts in primitivist style for an edition of Guillaume Apollinaire's first book of prose, L'enchanteur pourrissant (1909). He displayed works at the Neue Künstlervereinigung in Munich in 1910, in 1912 at the secessionist Der Blaue Reiter and in 1913 at the seminal Armory Show in New York. He also illustrated a collection of poems by Max Jacob in 1912.
During the German occupation of France in World War II, Derain lived primarily in Paris and was much courted by the Germans because he represented the prestige of French culture. Derain accepted an invitation to make an official visit to Germany in 1941, and traveled with other French artists to Berlin to attend a Nazi exhibition of an officially endorsed artist, Arno Breker. Derain's presence in Germany was used effectively by Nazi propaganda, and after the Liberation he was branded a collaborator and ostracized by many former supporters.
A year before his death, he contracted an eye infection from which he never fully recovered. He died in Garches, Hauts-de-Seine, Île-de-France, France in 1954 when he was struck by a moving vehicle.
Derain's London paintings were the subject of a major exhibition at the Courtauld Institute from 27 October 2005 to 22 January 2006.

HALE CRATER MOUNTAINS SEEN BY NASA MARS RECONNAISSANCE ORBITER





NASA MARS RECONNAISSANCE ORBITER MISSION (2005-2015)
Hale Crater Mountains  (150 kms diameter -  93 mile diameter)
Planet Mars  (Argyre quadrangle)

1 & 2. Hale crater mountains slope seeping waters
3. Hale crater mountains gullies.

The "mountains" 
Hale is a 150 km x 125 km (93 mi x 78 mi) crater located at 35.7°S, 323.4°E, just north of Argyre basin on Mars, the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury, often nicknamed "The red planet" because the iron oxide prevalent on its surface. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
The Hale crater is situated in the Argyre quadrangle of the planet.  
On 28 September 2015 NASA confirmed the seasonal existence of liquid water in Hale crater. The salts in the water (magnesium perchlorate, magnesium chlorate, sodium perchlorate,...) lower its freezing and melting point to 203 K (−70 °C or −94 °F), which is near the average summer night temperature. 

Hale was created by an asteroid roughly 35 km (22 mi) across that impacted at an oblique angle about 3.5–3.8 billion years ago. The rim and ejecta are eroded and show smaller impacts, but subsequent deposits have covered up small craters within it.  On the southern rim of Hale, parts of the crater wall have moved downslope towards the crater's centre. The surface shows a network of fluvial channels which may have been caused by running water.
It is named after George Ellery Hale, an astronomer from Chicago who determined in 1908 that sunspots are the result of magnetic activity.
The wall of Hale Crater has a large number of gullies. Some are pictured below in an image from HiRISE. Unlike, some other gullies on Mars, these are in light-toned materials. Research published in the journal Icarus has found pits in Hale Crater that are caused by hot ejecta falling on ground containing ice. The pits are formed by heat forming steam that rushes out from groups of pits simultaneously, thereby blowing away from the pit ejecta.
Gullies occur on steep slopes, especially craters. Gullies are believed to be relatively young because they have few, if any craters, and they lie on top of sand dunes which are young. Usually, each gully has an alcove, channel, and apron. Although many ideas have been put forward to explain them, the most popular involve liquid water either coming from an aquifer or left over from old glaciers.
There is evidence for both theories. Most of the gully alcove heads occur at the same level, just as one would expect of an aquifer. Various measurements and calculations show that liquid water could exist in an aquifer at the usual depths where the gullies begin. One variation of this model is that rising hot magma could have melted ice in the ground and caused water to flow in aquifers. Aquifers are layer that allow water to flow. They may consist of porous sandstone. This layer would be perched on top of another layer that prevents water from going down (in geological terms it would be called impermeable). The only direction the trapped water can flow is horizontally. The water could then flow out onto the surface when it reaches a break, like a crater wall. Aquifers are quite common on Earth. A good example is "Weeping Rock" in Zion National Park Utah.
On the other hand, much of the surface of Mars is covered by a thick smooth mantle that is thought to be a mixture of ice and dust. This ice-rich mantle, a few yards thick, smoothes the land, but in places it has a bumpy texture, resembling the surface of a basketball. Under certain conditions the ice could melt and flow down the slopes to create gullies. Because there are few craters on this mantle, the mantle is relatively young.
Changes in Mars's orbit and tilt cause significant changes in the distribution of water ice from polar regions down to latitudes equivalent to Texas. During certain climate periods water vapor leaves polar ice and enters the atmosphere. The water comes back to ground at lower latitudes as deposits of frost or snow mixed generously with dust. The atmosphere of Mars contains a great deal of fine dust particles. Water vapor will condense on the particles, then fall down to the ground due to the additional weight of the water coating. When ice at the top of the mantling layer goes back into the atmosphere, it leaves behind dust, which insulates the remaining ice.

The camera
The image above, has been captured by the HiRISE  (High Resolution Imaging Science Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter. The 65 kg (143 lb), $40 million USD instrument was built under the direction of the University of Arizona's Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp. It consists of a 0.5 m (19.7 in) aperture reflecting telescope, the largest so far of any deep space mission, which allows it to take pictures of Mars with resolutions of 0.3 m/pixel (about 1 foot), resolving objects below a meter across.
HiRISE has imaged Mars landers on the surface, including the ongoing Curiosity and Opportunity rover missions.
HiRISE was designed to be a High Resolution camera from the beginning. It consists of a large mirror, as well as a large CCD camera. Because of this, it achieves a resolution of 1 microradian, or 0.3 meter at a height of 300 km. (For comparison purposes, satellite images on Google Mars are available to 1 meter). It can image in three color bands, 400–600 nm (blue-green or B-G), 550–850 nm (red) and 800–1,000 nm (near infrared or NIR).
HiRISE incorporates a 0.5-meter primary mirror, the largest optical telescope ever sent beyond Earth's orbit. The mass of the instrument is 64.2 kg.
Red color images are at 20,048 pixels wide (6 km in a 300 km orbit), and Green-Blue and NIR are at 4,048 pixels wide (1.2 km). These are gathered by 14 CCD sensors, 2048 x 128 pixels. HiRISE's onboard computer reads out these lines in time with the orbiter's ground speed, meaning the images are potentially unlimited in height. Practically this is limited by the onboard computer's 28 Gbit (3.5 GByte) memory capacity. The nominal maximum size of red images (compressed to 8 bits per pixel) is about 20,000 × 126,000 pixels, or 2520 megapixels and 4,000 × 126,000 pixels (504 megapixels) for the narrower images of the B-G and NIR bands. A single uncompressed image uses up to 28 Gbit. However, these images are transmitted compressed, with a typical max size of 11.2 Gigabits. These images are released to the general public on the HiRISE website via a new format called JPEG 2000.
To facilitate the mapping of potential landing sites, HiRISE can produce stereo pairs of images from which the topography can be measured to an accuracy of 0.25 meter.
The HiRISE camera is designed to view surface features of Mars in greater detail than has previously been possible. It has provided a closer look at fresh martian craters, revealing alluvial fans, viscous flow features and ponded regions of pitted materials containing breccia clast.  This allows for the study of the age of Martian features, looking for landing sites for future Mars landers, and in general, seeing the Martian surface in far greater detail than has previously been done from orbit. By doing so, it is allowing better studies of Martian channels and valleys, volcanic landforms, possible former lakes and oceans, and other surface landforms as they exist on the Martian surface.
The general public is allowed to request sites for the HiRISE camera to capture (see HiWish). For this reason, and due to the unprecedented access of pictures to the general public, shortly after they have been received and processed, the camera has been termed "The People's Camera".
 The pictures can be viewed online, downloaded, or with the free HiView software.

LUSHAN / 庐山 PAINTED BY SHEN ZOU


SHEN ZOU (1427-1509)  
Lushan / 庐山  or Mount Lu (1,474m- 4,834ft) 
China

In Lofty Mount Lu  painted in 1467, National Palace Museum, Taipei

The mountain 
Mount Lu or Lushan  (庐山) is situated in the northern part of Jiangxi province in southeastern China, and is one of the most renowned mountains in the country. Mount Lushan is one of the spiritual centres of Chinese civilization. Buddhist and Taoist temples, along with landmarks of Confucianism, where the most eminent masters taught, blend effortlessly into a strikingly beautiful landscape which has inspired countless artists who developed the aesthetic approach to nature found in Chinese culture.
The oval-shaped mountains are about 25 km long and 10 km wide, and neighbors Jiujiang city and the Yangtze River to the north, Nanchang city to the south, and Poyang Lake to the east. Its highest point is Dahanyang Peak (1,474m- 4,834ft) and is one of the hundreds of steep peaks that towers above a sea of clouds that encompass the mountains for almost 200 days out of the year. Mount Lu is known for its grandeur, steepness, and beauty, and is part of Lushan National Park, a UNESCO World Heritage Site since 1996, and a prominent tourist attraction, especially during the summer months when the weather is cooler.
Lushan was a summer resort for Western missionaries in China. Absalom Sydenstricker, the father of Pearl Buck was one of the first five missionaries to acquire property in the Kuling Estate on the mountain.
Mount Lu was once dubbed the xiadu ("summer capital") of the Republic of China. Chiang Kai-Shek, China's leader at the time, would frequently spend his summers here. In June 1937, Zhou Enlai, then a major leader in the Communist Party, met with Chiang on the mountain to discuss a united front against the Japanese invasion. In July 1937, Chiang Kai-shek announced his intention for a full mobilization for war against Japan from Mount Lu. In 1946, following the war, the U.S. special diplomatic mission led by General George C. Marshall met with Chiang Kai-Shek to discuss the role of post-WWII China.
Mao Zedong convened three large conferences of senior party officials at Mount Lu, in 1959, 1961, and 1970. The 1959 conference became known as the Lushan Conference. The meeting saw the purge of decorated Chinese Civil War and Korean War general Peng Dehuai, who was critical of Mao's Great Leap Forward policies. The 1970 Lushan Conference took place during the Cultural Revolution, and marked the increasing antagonism between those loyal to Mao and those loyal to his chosen successor Lin Biao.
Mount Lushan has rich cultural and natural heritage, which authentically preserve the unique elements and characteristics of Mount Lushan’s creation, development and inheritance, including cultural, historical and natural elements such as ancient monuments and sites, villas, ancient stone inscriptions, paintings and poems dating to different historic periods, and streams and waterfalls, peaks and valleys. Temporary or partial damage of the ecological environment can be quickly and effectively restored. Restoration and intervention have followed principle of retaining the historic condition of the heritage in terms of design, materials, methods, and techniques. Thus, the property retains its historical authenticity, which permanently preserves the value of this “famous cultural mountain”.
In 1982, Mount Lushan became one of the first National Scenic Areas and one of the First Class National Nature Reserves, with the property area and buffer zone delimited. All attributes of Mount Lushan are effectively protected by the laws and regulations pertaining to the management of national scenic areas, and to the protection of cultural heritage and its setting. Any measures and projects that may significantly impact the heritage value must be authorized by the relevant national authorities.
The Lushan Scenic and Historic Interest Administrative Bureau focused on sustainable development of the property, and made increased investments in conservation and management. Both mid-term and long-term master plans for protecting the property have been made. Special attention has been placed on protecting the cultural heritages and their settings as a whole, and how to protect them more scientifically. Additional efforts have been made towards researching rational use of the property. Broad cooperation and exchanges have been undertaken. Conservation measures are strictly carried out. Environmental management and development projects are being tightly controlled. The right balance between heritage conservation and tourism development has been maintained, making it possible for the sustainable development of the property.

The artist 
Shen Zhou (Chinese: 沈周), courtesy name Qi'nan (启南) and Shitian (石田), was a Chinese painter in the Ming dynasty,  not be confused with another Chinese artist named Shen Zhou who lived between 1848 and 1903.  Shen Zhou’s scholarly upbringing and artistic training had instilled in him a reverence for China’s historical tradition that influenced both his life and his art from an early age. He was accomplished in history and the classics, and his paintings reveal a disciplined obedience to the styles of the Yuan dynasty, to China’s history, and to the orthodox Confucianism that he embodied in his filial life. He is most famous for his landscapes and for his “boneless” renderings of flowers, which are meticulously created in the style of the Yuan masters. However, he did not always paint within strict boundaries. His inherited prosperity afforded him the luxury of painting independently of patrons, and he did so in a way that, while revealing his historical influence, was uniquely his own. Shen possessed a large collection of paintings from the late Yuan and early Ming, which he and his scholar-painter colleagues used as models in forging the revivalist approach of the Wu style. He frequently combined experimental elements with the more rigid styles of the Yuan masters. Much of his work was done in collaboration with others, combining painting, poetry, and calligraphy at gatherings with his literati friends. It was upon these ideals that his Wu School was founded. For Wu painters, painting was a meditation, rather than an occupation. Shen Zhou never coveted his paintings, although they were frequently coveted and imitated by others. Through Shen Zhou’s eyes, a painting was not a commodity, but the very extension of the painter himself.

MOUNT ELEPHANT (DJERRINALLUM) BY EUGENE VON GUERARD

The mountain
Mount Elephant is a  (240 m -790 ft) conical breached scoria cone formed by a dormant volcano, located 1 km from the town of Derrinallum in southwestern Victoria, Australia. It is a prominent landmark that forms the eastern gateway to the Kanawinka Geopark from the Hamilton Highway at Derrinallum. Scoria cones are small volcanoes with relatively steep sides, usually formed as the result of a single major episode of volcanic activity. Lava lakes often form in the centre of scoria cones; if the lava in such a lake breaches the side of the cone, the result is a breached scoria cone, such as Mount Elephant. There are approximately 200 breached scoria cones in Victoria.
Mount Elephant was once quarried for its red/black scoria, and evidence of the quarry is visible at the base of its cone. The scoria that was quarried from Mount Elephant was used to make many of the roads and buildings in and around the town of Derrinallum.
The volcano is thought to have last erupted between 5,000 and 20,000 years ago making Mount Elephant dormant. During early European settlement, the mountain was known as Swagman's Lighthouse. The mountain was privately owned until 2000, when it was purchased by the Trust for Nature and the local community. The aim is to revegetate the area and promote local tourism.
In the nineteenth century, an Aboriginal name for Mount Elephant, Gerinyelam, was recorded by a colonist. During European colonization in 1830s, Mount Elephant was located within the territory of a Djargurd Wurrung clan, Teerinyillum gundidj.
According to James Dawson, "The Mount Shadwell tribe and its language are called 'Kirae wuurong,' 'blood lip' with Kuurndit ["member of"] affixed for a member of the tribe. Its territory commences at the Hopkins Hill sheepwash on the Hopkins River, and extends to Mount Fyans, Mount Elephant, Cloven Hills, Minninguurt, Mount Noorat, Keilambete Lake, Framlingham aboriginal station, and up the east side of the Hopkins River to starting point."
The photographer, Fred Kruger (1831-1888) took a photograph of King Tom, a survivor of the "Mount Elephant Tribe", at Coranderrk Settlement in the Yarra Valley (see Board for protection of Aborigines Album No. 131, Museum of Victoria.). King Tom lived at Meningoort Station, about 25 km south-west of Mount Elephant, north of Camperdown and west of Lake Bookaar. His mia-mia was near the homestead, and was painted by Robert Dowling in 1856. The painting, entitled "Aborigines in a bark hut: King Tom of the Mount Elephant tribe", is in the collection of the National Library of Australia. Meningoort Station still exists in Corangamite Shire and has remained in the McArthur family since Scottish immigrant, Peter McArthur, squatted on the land in 1837.
According to the Trust for Nature, "Even well before early European settlement, the local Indigenous community, the Djerrinallum gundidj, reputedly knew Mount Elephant as Djerrinallum – meaning 'Hill of Fire'. With their presence and a local history dating back as far as 45,000 years the Indigenous peoples of the area will certainly have witnessed a few of the eruptions in the region, including Mount Elephant. Therefore, it is of little wonder that some feature prominently in local Dreaming stories."

The Painter 
Johann Joseph Eugene von Guerard was an Austrian-born artist, active in Australia from 1852 to 1882. Known for his finely detailed landscapes in the tradition of the Düsseldorf school of painting, he is represented in Australia's major public galleries, and is referred to in the country as Eugene von Guerard. In 1852 von Guerard arrived in Victoria, Australia, determined to try his luck on the Victorian goldfields. As a gold-digger he was not very successful, but he did produce a large number of intimate studies of goldfields life, quite different from the deliberately awe-inspiring landscapes for which he was later to become famous. Realizing that there were opportunities for an artist in Australia, he abandoned the diggings and was soon undertaking commissions recording the dwellings and properties of wealthy pastoralists.
By the early 1860s, von Guerard was recognized as the foremost landscape artist in the colonies, touring Southeast Australia and New Zealand in pursuit of the sublime and the picturesque.  He is most known for the wilderness paintings produced during this time, which are remarkable for their shadowy lighting and fastidious detail.  Indeed, his View of Tower Hill in south-western Victoria was used as a botanical template over a century later when the land, which had been laid waste and polluted by agriculture, was systematically reclaimed, forested with native flora and made a state park. The scientific accuracy of such work has led to a reassessment of von Guerard's approach to wilderness painting, and some historians believe it likely that the landscapist was strongly influenced by the environmental theories of the leading scientist Alexander von Humboldt. Others attribute his 'truthful representation' of nature to the criterion for figure and landscape painting set by the Düsseldorf Academy.
In 1866 his Valley of the Mitta Mitta was presented to the National Gallery of Victoria in Melbourne; in 1870 the trustees purchased his Mount Kosciusko shown in this article was titled "Northeast view from the northern top of Mount Kosciusko", which is actually  "from Mount Townsend". 
In 2006, the City of Greater Geelong purchased his 1856 painting View of Geelong for A$3.8M. His painting, Yalla-y-Poora, is in the Joseph Brown Collection on display at the National Gallery of Victoria.  The State Library of New South Wales in Sydney holds an extensive collection of working sketchbooks by Eugene von Guerard, as well as larger drawings and paintings and a diary. The sketchbooks cover regions as diverse as Italy and Germany, Tasmania, New South Wales, and of course, Victoria.
In 1870 von Guerard was appointed the first Master of the School of Painting at the National Gallery of Victoria, where he was to influence the training of artists for the next 11 years. His reputation, high at the beginning of this period, had faded somewhat towards the end because of his rigid adherence to picturesque subject matter and detailed treatment in the face of the rise of the more intimate Heidelberg School style. Amongst his pupils were Frederick McCubbin and Tom Roberts. Von Guerard retired from his position at the National Gallery School the end of 1881 and departed for Europe in January 1882. In 1891 his wife died. Two years later, he lost his investments in the Australian bank crash and he lived in poverty until his death in Chelsea, London, on 17 April 1901.
Several paintings of mountains of Australia and New Zealand by Eugène von Guerard are published in this blog....
