The mountain
Mount Erebus (3, 794 m - 12, 448ft), not to be confused with Mount Elbrus is the second-highest volcano in Antarctica (after Mount Sidley) and the southernmost active volcano on Earth. It is the sixth highest ultra mountain on an island, located on Ross Island, which is also home to three inactive volcanoes: Mount Terror, Mount Bird, and Mount Terra Nova.The volcano has been active since c. 1.3 million years ago and is the site of the Mount Erebus Volcano Observatory run by the New Mexico Institute of Mining and Technology.
Mount Erebus was discovered on January 27, 1841 (and observed to be in eruption) by polar explorer Sir James Clark Ross who named it and its companion, Mount Terror, after his ships, Erebus and Terror (which were later used by Sir John Franklin on his disastrous Arctic expedition). Erebus is a dark region in Hades in Greek mythology. Present with Ross on the Erebus was the young Joseph Hooker, future president of the Royal Society and close friend of Charles Darwin. Erebus was an Ancient Greek primordial deity of darkness, the son of Chaos.
The mountain was surveyed in December 1912 by a science party from Scott’s Terra Nova Expedition who also collected geological samples. Two of the camp sites they used have been recognised for their historic significance:
- Upper “Summit Camp” site (HSM 89) consists of part of a circle of rocks, which were probably used to weight the tent valances.
- Lower “Camp E” site (HSM 90) consists of a slightly elevated area of gravel as well as some aligned rocks, which may have been used to weight the tent valances.
They have been designated Historic Sites or Monuments following a proposal by the United Kingdom, New Zealand and the United States to the Antarctic Treaty Consultative Meeting.
Mount Erebus is classified as a polygenetic stratovolcano. The bottom half of the volcano is a shield and the top half is a stratocone. The composition of the current eruptive products of Erebus is anorthoclase-porphyritic tephritic phonolite and phonolite, which are the bulk of exposed lava flow on the volcano. Erebus is the world's only presently erupting phonolite volcano.
Researchers spent more than three months during the 2007–08 field season installing an unusually dense array of seismometers around Mount Erebus to listen to waves of energy generated by small, controlled blasts from explosives they buried along its flanks and perimeter and to record scattered seismic signals generated by lava lake eruptions and local ice quakes. By studying the refracted and scattered seismic waves, the scientists produced an image of the uppermost (top few km) of the volcano to understand the geometry of its "plumbing" and how the magma rises to the lava lake. These results demonstrated a complex upper-volcano conduit system with appreciable upper-volcano magma storage to the northwest of the lava lake at depths hundreds of meters below the surface.
Climbing
Mount Erebus' summit crater rim was first achieved by members of Sir Ernest Shackleton's party; Professor Edgeworth David, Sir Douglas Mawson, Dr Alister Mackay, Jameson Adams, Dr Eric Marshall and Phillip Brocklehurst (who did not reach the summit), in 1908.
Its first known solo ascent and the first winter ascent was accomplished by British mountaineer Roger Mear on 7 June 1985, a member of the "In the Footsteps of Scott" expedition.
On January 19–20, 1991, Charles J. Blackmer, an iron-worker for many years at McMurdo Station and the South Pole, accomplished a solo ascent in approximately seventeen hours completely unassisted via snow mobile and on foot.
In 1992 the inside of the volcano was explored by Dante I, an eight legged tethered robotic explorer. Dante was designed to acquire gas samples from the magma lake inside the inner crater of Mount Erebus. Unfortunately, Dante I had not yet reached the bottom of the crater and so no data of volcanic significance was recorded.
The Painter
David Rosenthal is known as an Antarctic Painter, Painter of Ice, Arctic Artist, Alaskan Artist and an Extreme Artist. He has been lured to cold climates regularly to record snow, ice, and landscapes. Davids paintings of glaciers and icebergs are astoundingly realistic and at the same ethereal at the same time. However his work also includes much more than ice, icebergs and glaciers... Cordova, Alaska is the place David Rosenthal calls home. As an artist and art teacher David has taught and continues to teach many students in Alaska. While teaching art in Alaska, David has instructed students and artist in many programs including the Alaska Artists in the Schools Program, Prince William Sound Community College and University of Alaska Fairbanks Summer Sessions. Alaskan artist David Rosenthal makes it a priority to travel around Alaska as much as possible to continue to capture the incredible beauty in his artwork of Alaska.
Having spent over sixty months on the Ice, including four austral winters and six austral summers, David became an Antarctic artist and has created art images from a large variety of places in every season. David has completed paintings of the antarctic landscape from all across Antarctica. Time in Antarctica included travel as a participant in the National Science Foundation Antarctic Artists and Writers Program during a summer and a winter at McMurdo Station as well as most of a winter at Palmer Station. David has also worked for the NSF contractor for two winters and four summers in various job capacities as a way to spend time and become familiar with the landscape.
Rosenthal's work also includes many water colors, oil paintings, sketches and small studies. The paintings seem to magically reflect the intensity of nature's colors and the atmospheric phenomena that David witnesses. David really is a master of Extreme Art!
