Aracar

Aracar is a large conical stratovolcano in northwestern Argentina, just east of the Chilean border. It has an uneroded summit crater about 1.5 km (1 mi) in diameter which contains a small crater lake. It is located on the edge of the Puna de Atacama, a high desert plateau east of the Atacama Desert. The only observed volcanic activity was a possible steam or ash plume on March 28, 1993 seen from the village of Tolar Grande about 50 km (31 mi) southeast of the volcano.
