Michigan is a Midwestern state of the United States, located in the east north central portion of the country. It was named after Lake Michigan, whose name was a French adaptation of the Ojibwe term mishigami, meaning "large water" or "large lake".
Bounded by four of the five Great Lakes, plus Lake Saint Clair, Michigan has the longest freshwater shoreline in the United States, the ninth longest total shoreline (including island shorelines), and in 2005 had more registered recreational boats than any state except California and Florida. A person in Michigan is never more than 85 miles (137 km) from open Great Lakes water and is never more than 6 miles (10 km) from a natural water source.
Michigan is the only bi-peninsular state. The Lower Peninsula of Michigan, to which the name Michigan was originally applied, is sometimes dubbed "the mitten," owing to its shape. When asked where in Michigan one comes from, a resident of the Lower Peninsula may often point to the corresponding part of his or her hand. The Upper Peninsula (U.P.) is separated from the Lower Peninsula by the Straits of Mackinac, a five-mile channel that joins Lake Huron to Lake Michigan. The Upper Peninsula (whose residents are often called "Yoopers") is economically important for tourism and its natural resources.
The Upper and Lower Peninsulas are connected by the five-mile-long Mackinac Bridge, which is the third longest suspension bridge between anchorages in the world. This is the source of the name "trolls" for residents of the Lower Peninsula, for they live "under" (south of) the bridge. The Great Lakes that border Michigan are Lake Erie, Lake Huron, Lake Michigan and Lake Superior. Michigan also abuts Lake Saint Clair, which is between Lake Erie and Lake Huron.
