The large 7-8 km wide summit caldera of Alcedo volcano is seen in this aerial view from the south. Alcedo is one of the lowest and smallest of six shield volcanoes on Isabela Island; Darwin and Wolf volcanoes can be seen in the background. Much of the flanks and summit caldera are vegetated, but young lava flows are prominent on the northern flank near the saddle with Darwin volcano, and an active hydrothermal system lies within the caldera.
