Details for: Alcedo
Alcedo is one of the lowest and smallest of six shield volcanoes on Isabela Island. Seen here from the coast of Fernandina Island to its west, Alcedo has a 7-8 km wide summit caldera. Most of the flanks and summit caldera are vegetated, but young lava flows are prominent on the N flank near the saddle with Darwin volcano. Alcedo is the only Galápagos volcano known to have erupted rhyolite as well as basalt. Photo by Lee Siebert, 1978 (Smithsonian Institution).
