(For other ships with the same name, see List of ships named SS Ohio.) SS Ohio was a wooden hulled Great Lakes freighter that served on the Great Lakes of North America from her construction in 1875, to her sinking in September 1894 when she collided with the schooner barge Ironton which also sank in the collision. Ironton was being towed by the steamer Charles J. Kershaw, which was also towing the schooner Moonlight. Ohio was found upright in 2017, over 122 years after her sinking in over 200 feet of water off Presque Isle, Michigan. Ironton is still missing. The researchers who discovered Ohio plan to nominate her for a listing in the National Register of Historic Places.
