Friends of Thunder Bay National Marine Sanctuary

Thousands of miles of deep blue water in Thunder Bay are home to an estimated 200 shipwrecks, with nearly 100 identified to date. Majestic lighthouses, life-saving stations, and harbors further serve witness to the rich maritime history of Thunder Bay. Key to the Thunder Bay National Marine Sanctuary’s mission is protecting the Great Lakes and educating the public about these vast fresh waters and priceless treasures that rest along Lake Huron’s northwestern shores and bottomlands. Providing local support for the sanctuary’s mission is the driving force behind the Friends of TBNMS.
