Nevado Coropuna

Coropuna is a dormant compound volcano located in the Andes mountains of southeast-central Peru. The upper reaches of Coropuna consist of several perennially snowbound conical summits, lending it the name Nevado Coropuna in Spanish. The complex extends over an area of 240 square kilometres (93 sq mi) and its highest summit reaches an altitude of 6,377 metres (20,922 ft) above sea level. This makes the Coropuna complex the third-highest of Peru. Its thick ice cap is the most extensive in Earth's tropical zone, with several outlet glaciers stretching out to lower altitudes. Below an elevation of 5,000 metres (16,000 ft), there are various vegetation belts which include trees, peat bogs, grasses and also agricultural areas and pastures. The Coropuna complex consists of several stratovolcanoes. These are composed chiefly of ignimbrites and lava flows on a basement formed by Middle Miocene ignimbrites and lava flows. The Coropuna complex has been active for at least five million years, with the bulk of the current cone having been formed during the Quaternary. Coropuna has had two or three Holocene eruptions 2,100 ± 200 and either 1,100 ± 100 or 700 ± 200 years ago which generated lava flows, plus an additional eruption which may have taken place some 6,000 years ago. Current activity occurs exclusively in the form of hot springs. Coropuna is located 150 kilometres (93 mi) northwest of the city of Arequipa. People have lived on the slopes of Coropuna for millennia. The mountain was regarded as sacred by the Inca, and several archaeological sites have been discovered there, including the Inca sites of Maucallacta and Acchaymarca. The mountain was considered one of the most important Inca religious sites in their realm; human sacrifices were performed on its slopes, Coropuna forms part of many local legends and the mountain is worshiped to the present day.
