The twin volcanoes of Tolimán and Atitlán rise above the southern shores of Lake Atitlán in this view from the NNW. The surface of Tolimán (left) is draped by prominent thick lava flows. Many of the flows were erupted from vents on the volcano's flanks and form an irregular shoreline on the south side of Lake Atitlán. A lava flow from the parasitic lava dome of Cerro de Oro on the north flank entered Lake Atitlán and is less than a few thousand years old. No historical eruptions are known from Tolimán.
