GPS Location: N44° 59.020’ W82° 55.380’
Depth: 140 Feet
Wreck Length: 448 Feet Beam: 56 Feet
Gross Tonnage: 7076 Cargo: Steel
Built: 1943 by Rankin and Blackmore at Port Glasgow, Scotland
Wrecked: June 25, 1959
Description: Despite improved charts, navigational aids, designated shipping lanes, radio telephones, and even radar, big ships still go down in the Great Lakes. Such was the case when the Liberian registered ocean freighter Monrovia was rammed by the freighter Royalton during a heavy fog just outside Thunder Bay. Monrovia went to the bottom in deep water. The wreck sits upright on the lake bottom and is largely intact except for the collision damage.
