The two most prominent peaks of the Tres Vírgenes volcanic complex in central Baja California are seen here from the SSW. The peak to the left is El Azufre, a dacite lava dome complex. La Vírgen (right), consisting of andesite lava domes and flank scoria cones, formed more recently and has a more complicated history. It has erupted from both summit and flank vents and has produced both Plinian explosive eruptions and dacitic and andesitic lava flows.
