Acotango is stratovolcano lying on the border of Chile and Bolivia. It is 19,856 ft high and is the central and highest of a group of stratovolcanoes in the area. The group is known as Nevados de Quimsachata and consists of Acotango, Humarata (18,799 ft) to its north and Cerro Capurata (19,652 ft) on its south. This group of volcano lies in a north-south direction. Although the Acotango volcano is heavily eroded, a lava flow on its northern flank is morphologically young, suggesting Acotango was active in the Holocene.
