Researchers from NOAA, the state of Michigan, and Ocean Exploration Trust have discovered an intact shipwreck resting hundreds of feet below the surface of Lake Huron. Located within NOAA’s Thunder Bay National Marine Sanctuary, the shipwreck has been identified as the sailing ship Ironton. Magnificently preserved by the cold freshwater of the Great Lakes, the 191-foot Ironton rests upright with its three masts still standing. Learn more about the discovery.
