The Straits of Mackinac Shipwreck Preserve is a 148-square-mile (380 km) state preserve in and around the Straits of Mackinac. The preserve is divided in two by the Mackinac Bridge. The waters of the preserve include the waters offshore from Mackinaw City and St. Ignace, as well as all or part of the shorelines of Bois Blanc Island, Mackinac Island, Round Island, and St. Helena Island.
The preserve contains at least eleven identified diveable wrecks, with more just outside the official boundaries. There are also a number of shallow sites suitable for snorkeling and kayak visits. Frequent fog and congested shipping added to the count of shipwrecks in the Straits area. Half a dozen lighthouses in and around the preserve testify to the dangers that existed prior to the invention of radar in the 1940s. However, tragedies have continued. One modern wreck within the boundaries of the preserve is Cedarville, a lake freighter transporting limestone that sank in 1965 after a collision.
Divers also visit underwater formations of Mackinac breccia near Mackinac Island; one such formation, the "Rock Maze", is offshore from Arch Rock. Further east off Arch Rock, a drowned, 100-foot (30 m)-high waterfall formation, Mackinac Falls, was discovered in August 2007.
