The mountain
Cerro Aconcagua (6,961 meters -22,838 ft) is the highest mountain outside of Asia and by extension the highest point in both the Western Hemisphere and the Southern Hemisphere.
Aconcagua is not a volcano.
The origin of the name is contested; it is either from the Mapuche "Aconca-Hue", which refers to the Aconcagua River, the Quechua "Ackon Cahuak", meaning "Sentinel of Stone", or Quechua "Anco Cahuac", meaning "White Sentinel" or the Aymara "Janq'u Q'awa" meaning "White Ravine", "White Brook".
Aconcagua is located in the Andes mountain range, in the Mendoza Province, Argentina, and lies 112 kilometers (70 mi) northwest of its capital, the city of Mendoza and 108 km (67 mi) from Santiago de Chile (the capital of Chile). The summit is in fact located about 5 kilometers from San Juan Province and 15 kilometers from the international border with Chile; its nearest higher neighbor is Tirich Mir in the Hindu Kush, 16,520 kilometers (10,270 mi) away.
Aconcagua is one of the Seven Summit, which includes the highest mountains of each of the seven continents. The 7 summits (which are obviously 8 !)... are : Mt Everest (8,848m), Mt Denali or Mc Kinley (6,194m), Kilimandjaro (5,895m), Mt Elbrus (5,642m), Vinson Massif (4,892m), Mt Blanc (4,807m) and Mount Kosciuszko (2,228m). Summiting all of them is regarded as a mountaineering challenge, first achieved on April 30, 1985 by Richard Bass.
The mountain and its surroundings are part of the Aconcagua Provincial Park. The mountain has a number of glaciers. The largest glacier is the Ventisquero Horcones Inferior at about 10 km long, which descends from the south face to about 3600 m altitude near the Confluencia camp. Two other large glacier systems are the Ventisquero de las Vacas Sur and Glaciar Este/Ventisquero Relinchos system at about 5 km.
The photographer
Leo Wehrli was a Swiss geologist, professor and explorer. After studying music, botany, chemistry, mineralogy, petrography and geology in Berlin and Zurich, Wehrli became assistant to Albert Heim. Immediately after completing his thesis, he left for Argentina with the famous Carl Emanuel Burckhardt in 1896. Accredited by the La Plata Museum and the government of Argentina, he explored the Andes he crossed at least five times during a stay of two years. His work was more particularly oriented on the delimitation of the border between Argentina and Chile after the agreement signedbetween these two countries in 1881 and on the determination of the property of mountain peaks, ridge lines and basins slopes.
After his return to Switzerland, he worked between 1900 and 1935 as a teacher and then lecturer for the Geol. Centralblatt in Berlin ; between 1901 and 1912, he wrote nearly 500 articles. He made other trips through Europe and North Africa (Egypt) before going back to Argentina again in 1938. He has summarized his research results in numerous articles, notably in the Geographic Lexicon of Switzerland. He participated in the founding of the Zurich Adult Education Center and gave lectures there from 1921 to 1953. From 1931 to 1951 he was a member of the Swiss Alpine Club SAC commission for the Central Library and has was president for 14 years.
Wehrli left a collection of 15,000 slides, some of which were hand-colored by his wife, born Anna Frey. A large part of the works is made available online by the photographic archives of the ETH-Bibliothek in Zurich.
