Out of the five Great Lakes, Lake Michigan, the only one entirely within the borders of the United States, contains the largest number of shipwrecks, thanks to its past as a major navigational artery. Out of the known shipwrecks in the lake, 69 of them are listed on the National Register of Historic Places, within the waters of Michigan, Wisconsin, and Indiana.
