Where Wisconsin is

Wisconsin is the upper Midwestern state between two Great Lakes and the Mississippi. It measures about 310 miles north to south and about 260 miles east to west. Clockwise from the north: Lake Superior, Michigan's Upper Peninsula along the Montreal and Menominee rivers to the northeast, Lake Michigan and Green Bay to the east, Illinois along a surveyed line at 42°30'N to the south, Iowa across the Mississippi to the southwest, and Minnesota across the Mississippi and St. Croix rivers to the west. It is the 23rd-largest state by area and 20th by population.

Geography

Borders

Water forms most of Wisconsin's perimeter: the Mississippi with Iowa and most of Minnesota, the St. Croix with northern Minnesota, the two Great Lakes, and the Menominee, Brule and Montreal rivers with Michigan's Upper Peninsula. The only long surveyed line is the Illinois border at 42°30'N, which the 1818 Illinois enabling act moved north from the southern tip of Lake Michigan so that Illinois would have a lake shore, taking Chicago's site with it. The Minnesota line runs from the St. Croix headwaters straight to Lake Superior. In the lakes the boundaries with Michigan run through mid-lake.
