Divers flock to the Great Lakes to explore shipwrecks, calling the Great Lakes one of the best places in the world to see them because the freshwater preserves wrecks better than saltwater. According to the story, "the Great Lakes hold an estimated 6,000 to 10,000 sunken ships. About 1,000 Great Lakes shipwrecks have been identified, and about 10 new ships are discovered annually."
