The low ridge on the left-hand horizon is the southern rim of a large horseshoe-shaped caldera left by collapse of Miraflores, an andesitic ancestral stratovolcano of the Tecuamburro volcanic complex.  Miraflores volcano was formed about 100,000 years ago and collapsed sometime prior to 38,000 years ago.  The forested peak at the upper right is part of the compound Tecuamburro lava-dome complex, which was constructed within the collapse scarp. Photo by Lee Siebert, 1988 (Smithsonian Institution).
