The town of El Valle occupies the flat floor of El Valle de Antón caldera. This view from La India Dormida on the west caldera rim looks across the 6-km-wide caldera. A lake once covered the caldera floor, and large plinian phreatomagmatic eruptions took place during the latest Pleistocene from vents within the caldera. At the extreme left is Cerro Caracoral, the easternmost of three lava domes constructed along the northern caldera margin. The latest plinian eruptions originated from Mata Ahogado, east of the caldera rim at the left center.
