Coatepeque caldera is seen here from its northern rim, with Santa Ana volcano in the background. The caldera walls rise from 250 m to about 1 km above the lake and the stratigraphy is exposed in some areas. The rounded summit behind the caldera rim to the left is Cerro Verde, which was erupted along a NW-SE-trending fissure cutting through Santa Ana.
