The Andes is the longestcontinentalmountain range in the world. It is a continual range of highlands along the western coast of South America. This range is about 7,000 km (4,300 mi) long, about 200 km (120 mi) to 700 km (430 mi) wide (widest between 18° south and 20° southlatitude), and of an average height of about 4,000 m (13,000 ft). The Andes extend from north to south through seven South American countries: Argentina, Bolivia, Chile, Colombia, Ecuador, Peru, and Venezuela.
The Andes range is the world's highest mountain range outside of Asia. The highest peak, Mount Aconcagua, rises to an elevation of about 6,962 m (22,841 ft) above sea level. The peak of Chimborazo in the Ecuadorean Andes is farther from Earth's center than any other location on Earth's surface, due to the equatorial bulge resulting from Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border which rises to 6,893 m (22,615 ft). Over fifty other Andean volcanoes also rise above 6,000 m (19,685 ft).
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. However, the most well-known is the north-eastern or Polish Glacier, a common route of ascent.
