Cerro El Cóndor

The compound volcano of Cerro el Cóndor, one of the few large stratovolcanoes located wholly in Argentina, lies within a 2.5-km-wide caldera. The complex lies to the north of Falso Azufre volcano, which straddles the Chile/Argentina border. The summit contains several ash cones and craters that have been the source of a number of pristine lava flows, one of which traveled 10 km to the west. Satellitic centers also abound; one on the east flank produced a fresh-looking lava flow that traveled 8 km to the east. The morphologically youthful lava flows and pristine summit crater imply a Holocene age (de Silva and Francis, 1991).
