The western side of Lake Ilopango is seen from the southern rim of Ilopango caldera. The broad peak on the right-hand horizon is the Pleistocene Guazapa volcano. The northern wall of Ilopango caldera rises about 400-500 m above the lake. Much of the caldera rim contains thick caldera-forming eruption deposits, and some lava domes are exposed in the caldera wall.
