This is a photo of Volcan de las 3 Virgenes (the volcano of the 3 virgins). It is located near the E coast of Baja California, a region not usually noted for being volcanic. Volcan de las 3 Virgenes erupted last in the late 1700's. This photo has been annotated to show you that volcanoes are almost always made up of the products of many different eruptions, and even if they look like nice simple cones, they are actually quite complicated. Volcan de las 3 Virgenes has erupted a remarkable variety of lava types, namely basalt, andesite, and dacite.
