Nevados de Quimsachata Volcanic Complex is a -long volcanic group on a north-south alignment along the border between Bolivia and Chile, overseeing Chungara Lake. It contains three peaks, all stratovolcanoes.
Quimsachata means three in the Andean Aymara language, which is why some local people call these the "Three Sisters".
The group is formed N to S by Volcan Humarata - , Volcan Acotango - and Cerro Capurata - (also known as Cerro Elena Capurata). The active Volcan Guallatiri, to the west of C Capurata is not part of the group.
The Acotango stratovolcano is the central and highest of the three. It is in a fairly advanced stage of dissection, but a morphologically youthful lava flow on its northern flank suggests Holocene activity. Humarata, with a summit crater breached to the ESE, and Capurata, a complex of lava domes and associated pyroclastic-flow deposits, may also have been active during the Holocene.
