Three stratovolcanoes fill the southern half of Atitlán caldera in this view from the NE. Atitlán caldera formed during three major explosive eruptions from the Miocene to late Pleistocene. Atitlán volcano (far left) was constructed above the southern rim of the youngest caldera, Atitlán III, whose low southern rim is visible on the center horizon beyond narrow Santiago bay. Tolimán (right of Atitlán) and San Pedro (far right) overlie the rim of Atitlán II. The buried rim of Atitlán I lies below the shoreline of Tolimán.
