A panoramic view to the west across Lake Atitlán shows the flanks of Tolimán volcano extending to the lakeshore on the left, San Pedro volcano at the SW end of the lake, and the two peaks of Santo Tomás (left) and Santa María (right) on the center horizon. Tajumulco volcano appears in the distance at the upper right. Lake Atitlán occupies the northern half of the youngest Atitlán caldera, which formed during the eruption of the Los Chocoyos Ash about 84,000 years ago.
