El Valle de Antón caldera (left) is seen here where a late-Pleistocene lake occupied the caldera floor and persisted until it drained sometime during the Holocene. Cerro Cara Iguana (upper left) on the caldera rim contains El Hato pyroclastic flow deposits from caldera formation about 1.1-1.3 million years ago. A crater just out of view outside the SW caldera rim at the right was the inferred source of the India Dormida ignimbrite that was erupted about 220,000 years ago.
