Glacier-clad Volcán Parinacota rises to the NE above Laguna Chungará near the Chile-Bolivia border. The lake was formed when collapse of Parinacota about 8000 years ago produced a 6 cu km debris avalanche that traveled 22 km to the west and blocked drainages. Subsequent eruptions constructed the 6348-m-high symmetrical stratovolcano, which towers above late-Pleistocene andesitic-to-rhyolitic lava domes and flows in the middle ground.
