The town of El Valle occupies the El Valle de Antón caldera floor. This view looks across the 6-km-wide caldera from La India Dormida on the western rim. A lake once covered the caldera floor, contributing to large phreatoplinian eruptions during the late Pleistocene. At the far-left is Cerro Caracoral, the easternmost of three lava domes along the northern caldera margin. More recent Plinian eruptions originated from the Mata Ahogado crater, east of the caldera rim.
