The Great Lakes has served as passage to the Atlantic Ocean for hundreds of years. There is an area between Manitowoc, Wisconsin to Ludington, Michigan and south to Benton Harbor that has its history of mysterious disappearances comparable to the Bermuda Triangle.
The first known ship to go missing on Lake Michigan was Le Griffon which disappeared in 1679 while on her maiden voyage. It's estimated 1,500 ships have wrecked in Lake Michigan, but only 300 have been found.
