Atitlán (left) and Tolimán (right) are twin stratovolcanoes on the shores of Lake Atitlán, one of the scenic highlights of Guatemala. The historically active Atitlán is younger than Tolimán, although their activity overlaps. The surface of Tolimán is draped by prominent thick lava flows, in contrast to the extensive pyroclastic cover on Atitlán. Tolimán lava flows, erupted from both summit and flank vents, have produced a pronounced embayment with an irregular shoreline that extends into the lake. This view is from the NE on the rim of Atitlán caldera.
