Wisconsin - Geography

Geography

Wisconsin is bordered by the Montreal River; Lake Superior and Michigan to the north; by Lake Michigan to the east; by Illinois to the south; and by Iowa to the southwest and Minnesota to the northwest. A border dispute with Michigan was settled by two cases, both Wisconsin v. Michigan, in 1934 and 1935. The state's boundaries include the Mississippi River and St. Croix River in the west, and the Menominee River in the northeast. Wisconsin is the northernmost state that does not share a border with Canada.

With its location between the Great Lakes and the Mississippi River, Wisconsin is home to a wide variety of geographical features. The state is divided into five distinct regions. In the north, the Lake Superior Lowland occupies a belt of land along Lake Superior. Just to the south, the Northern Highland has massive mixed hardwood and coniferous forests including the 1,500,000 acres (6,100 km2) Chequamegon-Nicolet National Forest, as well as thousands of glacial lakes, and the state's highest point, Timms Hill. In the middle of the state, the Central Plain has some unique sandstone formations like the Dells of the Wisconsin River in addition to rich farmland. The Eastern Ridges and Lowlands region in the southeast is home to many of Wisconsin's largest cities. The ridges include the Niagara Escarpment that stretches from New York State, the Black River Escarpment and the Magnesian Escarpment. The bedrock of the Niagara Escarpment is dolomite, while the two shorter ridges have limestone bedrock. In the southwest, the Western Upland is a rugged landscape with a mix of forest and farmland, including many bluffs on the Mississippi River. This region is part of the Driftless Area, which also includes portions of Iowa, Illinois, and Minnesota. This area was not covered by glaciers during the most recent ice age, the Wisconsin Glaciation.

Overall, 46% of Wisconsin's land area is covered by forest. Langlade County has a soil rarely found outside of the county called Antigo Silt Loam.

Areas under the management of the National Park Service include the following:

• Apostle Islands National Lakeshore along Lake Superior
• Ice Age National Scenic Trail
• North Country National Scenic Trail
• Saint Croix National Scenic Riverway

There is one national forest managed by the U.S. Forest Service in Wisconsin, Chequamegon-Nicolet National Forest.

Wisconsin has sister-state relationships with the Germany's Hesse, Japan's Chiba Prefecture, Mexico's Jalisco, China's Heilongjiang, and Nicaragua.
