History and significance
On June 18, 1905, a thick fog draped over Lake Huron as the 414-foot steamer Etruria sailed toward Lake Superior with a load of coal. Suddenly, 10 miles off Presque Isle, the steamer collided with the south-bound 545-foot Amasa Stone . Etruria sank in minutes. Although Amasa Stone did not remain on the scene to assist after the collision, Etruria' s entire crew made it off the vessel safely and were rescued by another passing ship. A lengthy investigation followed. Both captains fought to clear their names. Insurance companies argued about liability for the large claim filed by Etruria 's owner. Ultimately, investigators concluded that Amasa Stone 's speed was the primary cause for Etruria' s sinking. Had it been traveling at a speed appropriate for the foggy weather, the collision could have been avoided, or the impact with Etruria would likely not have been substantial enough to sink the bulk carrier. Etruria 's final resting place was a mystery until 2011, when a research expedition called, “Project Shiphunt” sponsored by Sony & Intel Corporation and filmed by Radical Media led by Thunder Bay National Marine Sanctuary and partners, and including five high school students from Saginaw, Michigan, located and identified the ship. The completely intact Etruria rests upside-down in nearly 310 feet of water. Inner structure of Etruria .

Before you arrive
Access notes
Technical dive only. Confirm current conditions, mooring status, gas plan, decompression plan and operator requirements before departure. NOAA coordinates are reference points, not navigation instructions.
Plan within your training
Conditions and hazards
Depth beyond recreational limits, decompression obligations, cold water, limited light, changing visibility, entanglement and possible wreck overheads. Penetration requires separate wreck-penetration training and planning.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
