What is the highest peak in the Andes Mountains?

Aconcagua is the highest mountain outside of Asia, at 6,961 metres (22,838 ft), and by extension the highest point in both the Western Hemisphere and the Southern Hemisphere. It is located in the Andes mountain range, in the Mendoza Province, Argentina, and lies 112 kilometres (70 mi) northwest of its capital, the city of Mendoza. The summit is also located about 5 kilometres from San Juan Province and 15 kilometres from the international border with Chile; its nearest higher neighbor is Tirich Mir in the Hindu Kush, 16,520 kilometres (10,270 mi) away. It is one of the Seven Summits.

Aconcagua is bounded by the Valle de las Vacas to the north and east and the Valle de los Horcones Inferior to the west and south. 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 long. The most well-known is the north-eastern or Polish Glacier, as it is a common route of ascent.
