Photo Gallery

Casablanca volcano, whose summit is visible at the upper right, is the highest peak of the Antillanca volcano group. Raihuen crater (lower left) lies at the base of Casablanca. The Antillanca Group is a cluster of late-Pleistocene to Holocene scoria cones, maars, and small stratovolcanoes covering an area of 380 sq km SE of Lago Puyehue and NE of Lago Rupanco. Older late-Pleistocene stratovolcanoes have been extensively dissected by glaciers, but numerous small Holocene volcanic centers are present.
