Acotango is the central and highest of a group of stratovolcanoes straddling the border of Bolivia and Chile.[3][4] It is 6,052 metres (19,856 ft) high.[5][a][b] The group is known as Kimsa Chata and consists of three mountains: Acotango, Umurata (5,730 metres (18,799 ft)) north of it and Capurata (5,990 metres (19,652 ft)) south of it.
The group lies along a north–south alignment. The Acotango volcano is heavily eroded, but a lava flow on its northern flank is morphologically young, suggesting Acotango was active in the Holocene.[10] Later research has suggested that lava flow may be of Pleistocene age.[11] Argon-argon dating has yielded ages of 192,000±8,000 and 241,000±27,000 years on dacites from Acotango.[12] Glacial activity has exposed parts of the inner volcano, which is hydrothermally altered.[13] Glacial moraines lie at an altitude of 4,200 metres (13,800 ft) but a present ice cap is only found past 6,000 metres (20,000 ft) of altitude.[14]
The volcano is a popular hiking route in the Sajama National Park and Lauca National Park. It is on the border of two provinces: Chilean province of Parinacota and Bolivian province of Sajama. Its slopes are within the administrative boundaries of two cities: Chilean commune of Putre and Bolivian commune of Turco.[3][4]
To climb the summit from the Chilean side is dangerous due to land mines,[15] however it is relatively safe to climb the summit from the Bolivian side.[16] The southern ascent starts over a glacier and passes an abandoned copper mine.
