The Griffon, a 17th-century barque, is one of the greatest mysteries of the Great Lakes. She went missing in Lake Michigan in 1679 with a crew of six.  The final voyage of the Edmund Fitzgerald began November 9, 1975 at the Burlington Northern Railroad Dock No.1, Superior, Wisconsin. The SS Carl D. Bradley, built in 1927 and considered the “Queen of the Lakes” sank in 1957 in Lake Michigan, killing 33 of the 35 crew members. The Great Lakes bulk freighter SS John B Cowle sank in 1909 after a freak collision with another ship killing 14 of the 24 crew members aboard.  It has been estimated there are 25,000 shipwrecks in the Great Lakes!  Join the September episode of Great Lakes Chronicles: Tales from the Great Lakes as we investigate the mysteries and lore with our guest Sean Ley, Director of Development of the Great Lakes Shipwreck Museum.
