Tres Virgenes

Tres Vírgenes is a complex of volcanoes located Mulegé Municipality in the state of Baja California Sur, on the Baja California Peninsula in northwestern Mexico. It is composed of three volcanoes, aligned northeast-southwest, with El Viejo, the oldest, to the northeast, El Azufre in the middle, and the youngest, El Vírgen, to the southwest. El Vírgen, being by far the most conspicuous of the three, is commonly known as "Las Tres Vírgenes". The last known eruption was in 1746.
