St. Andrew wreck, Lake Michigan
Lake Michigan is one of the five Great Lakes, the only one placed entirely within the United States and the second largest Great Lake by volume. It has the same surface elevation as Lake Huron, making the two technically a single lake. The Straits of Mackinac connects Lake Michigan and Lake Huron. Over the years, many ships have sunk in the Straits. One of the shipwrecks lying in the Straits of Mackinac Underwater Preserves is St. Andrew.
