Cerro Alto (right) is a scoria cone on the SE flank of Coatepeque caldera, seen here from the southern caldera rim. Basaltic lava flows were erupted from the eastern side of the cone. Cerro Alto predates the formation of Coatepeque caldera and is overlain by deposits from the caldera-forming eruptions. San Salvador volcano is on the horizon to the east (left).
