Multiple craters truncate the summit of Láscar volcano (left of center), and prominent lava flow levees are visible on its western flank. To the east is the symmetrical cone of Láscar's higher twin volcano, Aguas Caliente (right of center), with its smaller circular summit crater that contains a shallow lake. The most recent activity at this E-W-trending volcanic chain originated from Láscar volcano and continued into historical time.
