Site details

The Norman, an 1890 Globe Iron Works steel steamer and one of the first propeller-driven steel lakers, sank in a 1895 collision and lies 10.5 miles east-southeast of Presque Isle in Lake Huron. She sits broken in two with a 45-degree port list in 170-210 ft of water, her double-wheeled wheelhouse lying alongside and a yawl boat and massive collision hole on display. Cold water has preserved her superbly, making her one of the marquee technical dives of the Thunder Bay National Marine Sanctuary's deep Presque Isle group.
