The resort town of Panajachel (right-center) occupies a delta of the river of the same name that flows into Lake Atitlán.  The northern caldera rises up to 1100 m above the lake.  Rapid sedimentation following formation of the caldera about 84,000 years ago has filled in about half of the roughly 600 m depth of the caldera below the lake surface.  The level of the lake has fluctuated more than 10 m over periods of several decades, and titles exist to land now submerged hundreds of meters from the current shoreline.  High heat flow is present in the lake. Photo by Lee Siebert, 1988 (Smithsonian Institution).
