60 000 000 2010
Outside of Asia, Aconcagua is the highest mountain, at 6,960.8 metres (22,837 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.
The mountain was created by the subduction of the Nazca Plate beneath the South American Plate during the geologically recent Andean orogeny; but it 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 and means "comes from the other side", the Quechua Ackon Cahuak, meaning "'Sentinel of Stone", or Quechua Anco Cahuac, "White Sentinel" or the Aymara Janq'u Q'awa, "White Ravine", "White Brook"
