Shipwreck · Alpena, Michigan

Monohansett

A 160-foot wooden steam barge launched in 1872 at Gibraltar, Michigan. On November 23, 1907, carrying coal, she caught fire when an oil lantern tipped over, and her crew abandoned ship. She lies just below the surface in about 18 ft (5 m) of clear water off Thunder Bay Island, visited by divers, snorkelers, paddlers and a glass-bottom boat. In Thunder Bay National Marine Sanctuary: use the mooring buoys. Look, don’t touch, and take nothing: removing or damaging anything on the wreck is illegal.
