English: Volcán Darwin, named after the celebrated naturalist, rises above a narrow channel opposite Point Espinosa on the NE tip of Fernandina Island. Darwin volcano contains a symmetrical 5-km-wide summit caldera that is nearly filled by lava flows. The most recent summit activity produced several small lava flows from vents on the east caldera floor and NE and SE caldera rims. Two breached tuff cones on the SW-flank coast, Tagus and Beagle, were a prominent part of Darwin's geological studies in the Galápagos Islands.
