The 6-km-long, dagger-like Santiago Bay on Lake Atitlán is constrained by lava flows from San Pedro (upper left) and Tolimán (right-center) volcanoes. Young lava flows entering the lake, in particular those from Tolimán, have created a very irregular shoreline. The unvegetated summit of Atitlán volcano, the youngest post-caldera stratovolcano, lies south of Tolimán. Part of the southern margin of the Atitlán III caldera, which lies below the summit of Atitlán volcano, is offset along faults just south of the tip of Santiago Bay.
