Acotangois the central and highest of a group ofstratovolcanoesstraddling the border ofBoliviaandChile.[3][4]It is 6,052 metres (19,856 ft) high.[5][a][b]The group is known asKimsa Chataand consists of three mountains: Acotango,Umurata(5,730 metres (18,799 ft)) north of it andCapurata(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 theHolocene.[10]Later research has suggested that lava flow may be ofPleistoceneage.[11]Argon-argon datinghas yielded ages of 192,000±8,000 and 241,000±27,000 years ondacitesfrom Acotango.[12]Glacial activity has exposed parts of the inner volcano, which is hydrothermally altered.[13]Glacialmoraineslie 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 theSajama National ParkandLauca National Park.It is on the border of two provinces: Chilean province ofParinacotaand Bolivian province ofSajama.Its slopes are within the administrative boundaries of two cities: Chilean commune ofPutreand 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.
First Ascent and human presence
[edit]Acotango's first modern ascent was by Sergio Kunstmann, Pedro Rosende and Claudio Meier (Chile) October 14, 1965.[2]It is believed that Pedro Rosende, a Chilean explorer, found the remains of firewood at the summit of Acotango. Because of this, it is thought that the mountain might have been one of the high Incan Andean sanctuaries. However, more exploration is needed to verify this information.[17]
