The tuff cones of Tagus (upper left) and Beagle (lower right) were formed by phreatomagmatic eruptions at Darwin volcano in the Galápagos Islands. The rim of Tagus is breached by Tagus Cove that was visited by Charles Darwin's vessel, the Beagle. Tagus tuff cone has at least four nested craters, the youngest of which contains a small salt lake. Young black lava flows from fissures on the flanks largely surround the tuff cones.
