The Tuzo Wilson Seamounts are two submarine volcanic edifices that are located 50 km southwest of the Queen Charlotte Islands, offshore British Columbia. These geologically-recent features have formed on the boundary between the Pacific and Explorer plates in the vicinity of their triple junction with the North American plate.
