DETROIT — Events in Michigan are observing the 40th anniversary of the sinking of the Edmund Fitzgerald on Lake Superior.

A sculpture by Timothy P. Schmalz titled “The Wreck of the Edmund Fitzgerald” is being revealed Tuesday afternoon at the Dossin Great Lakes Museum in Detroit.

The sculpture will be on display through the spring, when it will be moved to its permanent location at the Great Lakes Shipwreck Museum in Michigan’s Upper Peninsula.

Memorial ceremonies are Tuesday night at both museums.

The freighter went down Nov. 10, 1975, killing 29 crewmen. The sinking spawned a well-known song by Gordon Lightfoot, “The Wreck of the Edmund Fitzgerald.”

On Sunday, a service at Mariners’ Church in Detroit included family members of some of those who died in the sinking.
