About Keystorm
Keystorm is a historic steel freighter wreck in the St. Lawrence River near Chippewa Bay. The wreck lies on its side, so divers can start shallow on the bow, follow the hull toward the stern, and work through large structure, engine-room areas, and open holds. It is best planned as a boat dive with river flow, cold-water conditions, and cross-border logistics in mind.
