The deep blue waters of Lago de Coatepeque fill the eastern side of Coatepeque caldera.  Post-caldera lava domes, including the rounded island of Cerro Grande (Isla de Cabra) on the left at the far side of the lake and flat-topped Cerro Pacho (the low lighter colored area to its right below the caldera rim), were erupted along a E-W-trending line.  The rounded hill on the right horizon is Cerro Verde.  Photo by Lee Siebert, 2002 (Smithsonian Institution).
