Volcán Tolimán (center) towers above the south shore of scenic Lake Atitlán.  Tolimán and its conical twin volcano Atitlán (upper left) were constructed within the Pleistocene Atitlán III caldera, near its inferred southern margin.  In contrast to the tephra-covered surface of Volcán Atitlán, the surface of Tolimán is draped by prominent thick lava flows.  The recent history of Tolimán is dominated by effusive eruptions from flank vents.  The resulting lava flows extend into the lake and produce a highly irregular shoreline.
