This view from the SE shows the Tres Vírgenes volcanic group, which is aligned in a SW-NE direction. Volcanism has migrated to the SW from the oldest peak El Viejo (far right) through El Volcán Azufre to La Vírgen (center), the highest peak. The ridges on the left flank of La Vírgen are rhyodacite lava flows from a major eruption; the smooth hills in the foreground are Quaternary ignimbrite sheets probably related to the Pleistocene La Reforma caldera to the east.
