Kimsa Chata or Kimsachata (Aymara and Quechua kimsa three, Pukina chata mountain, "three mountains", hispanicized Quimsa Chata, Quimsachata) is a 8 km (5 mi)-long volcanic complex on a north-south alignment along the border between Bolivia and Chile, overseeing Chungara Lake. It contains three peaks, all stratovolcanoes. The group is formed - from north to south - by Umurata (5,730 m (18,799 ft)), Acotango (6,052 m (19,856 ft)) and Capurata (5,990 m (19,652 ft)) (also known as Cerro Elena Capurata). The active volcano Guallatiri (Wallatiri) west of Capurata is not part of the group.
