Lake Effect: Shipwrecks of the Great Lakes
The Scotiadoc: The Deadly Collision on Lake Superior
On June 20, 1953, the Scotiadoc, a 49-year-old Great Lakes freighter loaded with wheat, pushed out onto Lake Superior as thick fog swallowed everything around her. Somewhere in that gray wall, another massive freighter was moving in the opposite direction. The ships had radar. Their fog whistles were sounding. Their crews knew another vessel was somewhere nearby. But they couldn't see it. As the distance between the two freighters closed, routine fog signals suddenly became urgent danger blasts. Then, out of the gray, a dark shape appeared. In this episode of Lake Effect, we follow the Scotiadoc's final voyage through the fog off Thunder Cape and Trowbridge Island, the terrifying moments aboard both ships, the desperate fight to escape Lake Superior, and a mystery that would remain hidden beneath the lake for decades. This is the haunting true story of the SS Scotiadoc, one of Lake Superior's most dramatic and remarkable shipwrecks.
