Coatepeque caldera is seen here from the SSW at the summit of Cerro Verde, a flank cone of Santa Ana volcano.  Lago de Coatepeque fills the NE part of the 7 x 10 km caldera.  The younger SW side of the caldera partially truncates Santa Ana volcano and extends to the sudden break in slope seen in the lower part of the photo.  The caldera floor is higher on this side as a result of the accumulation of volcaniclastic debris from Santa Ana volcano and the eruption of a series of post-caldera lava domes, one of which forms the island at the right-center.
