Lake Atitlán fills the northern half of the Atitlán III caldera, which formed about 84,000 years ago following eruption of the Los Chocoyos Ash. The 18-km-long caldera lake is seen here from the south, with the flanks of the post-caldera Tolimán volcano in the foreground. The relatively flat lake floor is 300 m below the water surface, and caldera walls rise to about 1 km above the lake.  Photo by Bill Rose, 1980 (Michigan Technological University).
