An active sulfur mine is located north of Cerro Sairecabur volcano. This chain of volcanoes along the Chile-Bolivia border contains at least 10 postglacial centers. The highest peak, Sairecabur, is located at the northern margin of a 4.5-km-wide caldera. Postglacial activity began south of the summit, but most recently produced a pristine lava flow to the NW. Escalante, at the northern end of the chain, has a crater lake at its summit and youthful lava flows on its flanks. Other eruptive centers have also produced Holocene lava flows.
