Cerro San Roque (left), Cerro Gongora (center), and Cerro Canas Dulces (right), seen here from the west along the Pan-American highway, are rhyodacitic lava domes just outside the Guachipelín caldera.  The domes were formed prior to eruption of the Liberia Tuff and formation of the caldera about 1.6 million years ago. Photo by Lee Siebert, 1998 (Smithsonian Institution).
