Volcan de las 3 Virgenes, Baja California
Location: 27.5N, 112.6W
Elevation: 6,365 feet (1,940 m)
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.
