Thousands of years ago, most of Wisconsin was visited by glaciers, scraping the tops off hills, leaving
rich earth deposits and leaving a land of beautiful lakes (15,000 of them) resting in fertile plains and valleys arranged
between rolling hills and ridges. This state can be divided into five geographical land areas; the Lake
Superior Lowland, the Eastern Ridges and Lowlands (Great Lakes Plains), the Northern Highland, or Superior
Upland, the Central Plain and the Western Upland.
Lake Superior Lowland: In northern Wisconisin, the
Lake Superior Lowland
slopes gradually upwards
toward the south from the shores of Lake Superior. This small area of flat plain extends about 5 to 20 miles
Northern Highland: Most of northern Wisconsin is characterized by
This area, lying south of the Lake Superior Lowland, expands into about 1/3 of the sate. The Norther Highland
reaches its highest elevations in the north, sloping downward to the south. The Northern Highland
supports hundreds of small lakes and heavily forested hills.
the highest point in Wisconsin, is located in the Northern Highland.
Central Plain: South of the Northern Highland and curving across the central part of the state is
an area of
In the southern portion of the Central Plain, the Wisconsin River has carved the beautiful scenic gorge,
This is an area of buttes and mesas; an unexpected landscape for central Wisconsin.
Eastern Ridges and Lowlands: To the east of the Central Plain, the gently rolling hills of the
Eastern Ridges and Lowlands
area extends from Green Bay south to Illinios. This is the richest agricultural
region of Wisconsin where ice-age glaciers deposited earth over limestone ridges.
Western Upland: To the west of the Central Plain the
is characterized by limestone
and sandstone bluffs along the Mississippi River. The Western Upland extends along the Mississippi River
to the border of Illinios. The southwestern portion of the Western Upland was not touched by glaciers and
is an area that supports steeply sloped ravines and winding ridges.
