Shipwrecks, piers, invasive species, even cars: A look at the bottom of Lake Michigan

A shipwreck boiler sits just under the water line at South Fox Island, off the tip of the Leelanau Peninsula of Michigan. The Eber Ward had picked up corn in Milwaukee and was bound for Port Huron when it ran into ice in the Straits of Mackinac in 1909. The bow was torn off and it sank within 10 minutes.
