Nevado del Sajama, rising to 6542 m about 20 km east of the Chilean border, is Bolivia's highest mountain.  The steep-sided volcano is seen here from the Chilean side of the border, rising above Laguna ChungarĂ¡, which was formed when a debris avalanche from Parinacota volcano (out of view to the left) blocked drainages.  Sajama consists of an andesitic stratovolcano overlying andesitic-to-rhyodacitic lava domes.  Pleistocene lava flows from Parinacota form the ridge at the left, and the flanks of Pleistocene Quisiquisini volcano rise to the right. Photo by Lee Siebert, 2004 (Smithsonian Institution).
