The Edmund Fitzgerald sank on November 10, 1975. Background:

• The 729-foot freighter disappeared during a severe late-autumn storm on Lake Superior, northwest of Whitefish Bay, Michigan.

• All 29 crew members were lost, and the wreck was found days later in deep water, confirming the ship broke apart as the storm overwhelmed it.

• The tragedy has become a landmark in Great Lakes maritime history and is widely commemorated, including through Gordon Lightfoot’s song “The Wreck of the Edmund Fitzgerald”.
