Volcán Tolimán (center) towers above the south shore of scenic Lake Atitlán. Tolimán and the adjacent 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 dominated by thick lava flows. The recent eruptions of Tolimán were primarily effusive eruptions from flank vents. The resulting lava flows extend into the lake and produce the irregular shoreline.
