The paired Atitlán-Tolimán volcanoes rise above Lake Atitlán in this view from the town of Solola north of the lake. Atitlán, Tolimán's higher twin volcano, forms the skyline immediately behind and to the left of Tolimán. Cerro de Oro, a flank lava dome, seen here immediately above the lakeshore left of the summit, erupted within the past few thousand years. The two volcanoes were constructed over the buried rims of two Miocene-Pleistocene Atitlán calderas.
