The Sandusky is an 1848 two-masted brig, the oldest known dived shipwreck in the Straits of Mackinac Shipwreck Preserve, lost with all hands in a September 1856 gale while carrying grain from Chicago to Buffalo. Her hull sits intact in about 85 ft of Lake Michigan five miles west of the Mackinac Bridge, slightly heeled to port, with deck depths around 70 ft. A replica scroll figurehead adorns the bow below the intact jib-boom, and the windlass, bilge pumps and centerboard winch remain in place; a seasonal mooring buoy marks the site.
