Colonel Ellsworth wreck, Lake Michigan
Lake Michigan is the second largest Great Lake by volume and the only one located entirely in the United States. The lake’s shoreline is more than 1600 mi/2575 km and the average depth is 195 ft/59.4 m. Lake Michigan and Lake Huron have the same surface elevation and are technically a single lake. They are actually connected by the Straits of Mackinac, where many ships have foundered due to heavy storms. The Straits of Mackinac Underwater Preserve, located at the northern edge of Lakes Michigan and Huron, tries to preserve Michigan’s shipwrecks for next generations. One of the shipwrecks found is Colonel Ellsworth.
