The western side of Lake Ilopango is seen from the southern rim of Ilopango caldera.  The broad peak on the right-hand horizon is Guazapa, a Pleistocene volcano in the Interior Valley of El Salvador that has young pyroclastic cones at its base.  The northern wall of Ilopango caldera rises about 400-500 m above the lake.  Much of the caldera rim is covered with a thick blanket of deposits from the caldera-forming eruptions, but some lava domes are exposed in the caldera wall.
