Appropriately nicknamed the "Great Lake State," Michigan is known for the surrounding Great Lakes that cover roughly 3,000 miles of its shoreline. Together, the five bodies of water account for approximately one-fifth of the freshwater on the planet.
The largest of the Great Lakes, Lake Superior rests along the northern coast of the state's Upper Peninsula. Covering 31,700 square miles with an average depth of 483 feet, Superior contains roughly three quadrillion gallons of water.
Nearly identical in size, Lake Michigan and Lake Huron are adjoined by the Straits of Mackinaw between the Lower and Upper Peninsulas, which are connected by the Mackinaw Bridge. Lake Michigan runs along the entire western coast of the state and the eastern half of the southern Upper Peninsula, while Huron borders the northern half of the mitten and the eastern Upper Peninsula.
Lake Erie is the warmest of the Great Lakes and fourth-largest in surface area. Erie touches three other states and has major cities of Toledo and Cleveland, Ohio; Erie, Pennsylvania; and Buffalo, New York, resting along its shores.
Easternmost Lake Ontario is the only Great Lake that does not share a land border with Michigan. The smallest of the Great Lakes in size, it is still the 14th-largest freshwater lake in the world.
