From Wikipedia, the free encyclopedia

Coropuna is a dormant volcano with several perennially snowbound conical summits in the Andes mountains of southern Peru. The highest peak of the compound volcano reaches an altitude of 6,377 metres (20,922 feet) above sea level, making the Coropuna complex the third-highest in 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 feet), the vegetation belts include trees, peat bogs and grasses, as well as agricultural areas and pastures. The Coropuna complex consists of several stratovolcanos composed chiefly of ignimbrites and lava flows, on a basement formed by similar material from the Middle Miocene. The complex has been active for at least five million years. Current activity occurs exclusively in the form of hot springs. The Inca archaeological site of Mawk'allaqta is on the volcano's slopes.
