The 4300 square mile Thunder Bay National Marine Sanctuary is situated in northwest Lake Huron, one of the most dangerous stretches of water in the Great Lakes. Mist, fog, gale force winds, ice and rocky shoals have made shipping hazardous in the area. Coupled with human error, the unpredictable conditions have been responsible for over 200 shipwrecks, involving a variety of vessels. More than 100 have been discovered and, with modern technology, more are being found. The sanctuary is mandated to research, monitor and protect this maritime heritage, along with the many historic buildings on shore, such as lighthouses, lifesaving structures, docks and boats. The sanctuary is open year round.
