An aerial view of the western side of Coatepeque caldera shows Cerro la Isla lava dome forming the island at the left center. On the ridge behind the caldera wall are (from left to right) the San Marcelino-La Olla and El Conejal-El Astillero pyroclastic-cone complexes, the tip of Izalco volcano, rounded Cerro Verde scoria cone, and (in the clouds) the summit of Santa Ana volcano. The Pacific Ocean is visible in the distance.
