Located in northwestern Lake Huron, Thunder Bay is adjacent to one of the most treacherous stretches of water within the Great Lakes system, earning the area the name of, "Shipwreck Alley." Today, the 448-square-mile Thunder Bay National Marine Sanctuary protects one of America's best preserved and nationally significant collections of shipwrecks. It also encompasses all of the cultural and natural features related to maritime heritage. Lifesaving stations, lighthouses, historic boats and ships, commercial fishing camps, docks, and working ports are among the more obvious historic and archaeological features.
