This is the retired Michigan State auto ferry Straits of Mackinac, intentionally scuttled as a dive reef in southern Lake Michigan on April 10, 2003; dive-resource sources disagree on the exact distance and direction from Chicago's Navy Pier (about 10 miles north per one source, about 14 miles per another), so this position is only an approximate dive-community estimate, not a surveyed fix.
