Volcán San Pedro (upper right) is the oldest of three stratovolcanoes constructed within Atitlán caldera.  The furrowed slopes of the volcano contrast with the less dissected flanks of the twin Atitlán and Tolimán volcanoes.  Cerro de Oro, the small lava dome just beyond the shore of Lake Atitlán at the left, is a flank lava dome of Tolimán volcano.  Youthful lava flows from Tolimán descend into the lake and form part of its southern shore in this view from the west.   Photo by Bill Rose, 1978 (Michigan Technological University).
