Mission

Protecting the Great Lakes and their rich maritime history through research, education and resource protection. The sanctuary works to ensure that future generations can enjoy these underwater treasures.

About Us
Thunder Bay National Marine Sanctuary 
Located in northwestern Lake Huron, Thunder Bay is adjacent to one of the most treacherous stretches of water within the Great Lakes system, learning the area the name of “Shipwreck Alley.” Today, the Sanctuary protects one of America’s best-preserved and nationally significant collections of shipwrecks. Visit the Great Lakes Maritime Heritage Visitor Center to explore more.
