Researchers from National Oceanic and Atmospheric Administration (NOAA), the state of Michigan, and Ocean Exploration Trust have discovered an intact shipwreck resting hundreds of feet below the surface of Lake Huron. The shipwreck has been identified as the sailing ship Ironton. Magnificently preserved by the cold freshwater of the Great Lakes for over a century, the 191-foot Ironton rests upright with its three masts still standing.
