The smallest of at least four nested craters on Tagus tuff cone, located on the SW flank of Darwin volcano, is filled by a small lake. The ridge at the upper left is the SE rim of the tuff cone, which is breached by Tagus Cove, one of the most renowned anchorages in the Galápagos archipelago. Cerro Azul shield volcano rises in the distance at the southern end of Isabela Island.
