Sajama volcano in Bolivia towers beyond the Chilean border above Laguna Chungará. Blocky Pleistocene lava flows from Parinacota volcano, out of view to the left, extend across the middle of the photo. Sajama is Bolivia's highest peak and rises about 2000 m above its base. The dominantly andesitic volcano overlies andesitic-to-rhyolitic lava domes.
