Volcán el Puerto (left) and Volcán Embarcadero (right) are seen from the east across fields of the Mascota graben. Both cones have craters that open towards the east. They are in the NW side of the Mascota Volcanic Field and erupted near the western base of the graben walls, which in this view consists of metamorphic rocks and elsewhere of Cretaceous tuffs. The Mascota graben here is about 5 km wide.
