Photo Gallery

The compound Mocho-Choshuenco volcano, seen here from the SW, is composed of two glacier-covered stratovolcanoes post-dating a 4-km-wide caldera. Choshuenco (left), was constructed during the late Pleistocene on the NW rim of the caldera. The andesitic-to-dacitic, 2422-m-high El Mocho (center), is a small cone that grew within the caldera and has remained active into historical time.
