The Pampa Luxsar lava field consists of a 45 x 45 km area of coalesced lava flows at the SW margin of Bolivia's Salar de Uyuni, east of the Andean volcanic front. Several generations of lava flows and cones are present, but the youngest flows of the volcanic field, also spelled Pampa Luxar, were considered to be Holocene or late Pleistocene in age (de Silva 2007, pers. comm.). The young lava field partially or completely surrounds the older dissected stratovolcanoes of Cerro Luxsar and Cerro Uquila.
