Santa Ana volcano rises above scenic Lago de Coatepeque. The 6-km-wide lake lies at the eastern end of the compound Coatepeque caldera. The northern and southern rims of the western side of the caldera are visible beyond the lake. The rounded peak to the left of Santa Ana is Cerro Verde, one of many cones constructed along a NW-SE-trending fissure cutting across the Santa Ana complex.
