Cabo Cowan is a tuff cone at the NW tip of Santiago Island in the Galápagos Islands. Wave erosion has truncated the flanks of the cone, forming vertical sea cliffs that expose its interior stratigraphy. The cone is located where the NW-trending rift zone along the crest of Santiago shield volcano encounters the sea.
