Michigan is the only state to consist of two peninsulas. The Lower Peninsula, to which the name Michigan was originally applied, is often noted to be shaped like a mitten. The Upper Peninsula (often referred to as “the U.P.”) is separated from the Lower Peninsula by the Straits of Mackinac, a five-mile (8 km) channel that joins Lake Huron to Lake Michigan. The two peninsulas are connected by the Mackinac Bridge. This page may not include all the maps we carry for the state of Michigan but these are some of the more popular maps.
