The Driftless Area comprises southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois in the American Midwest. It was never covered by ice during the last ice age, and therefore lacks glacial deposits, also termed drift. Its landscape is characterized by steep hills, forested ridges, deeply carved river valleys, and karst geology with spring-fed waterfalls and cold-water trout streams. Ecologically, the Driftless Area's flora and fauna are more closely related to those of the Great Lakes region and New England than those of the broader Midwest and central Plains regions. The steep riverine landscape of both the Driftless Area proper and the surrounding Driftless-like region are the result of early glacial advances that forced preglacial rivers that flowed into the Great Lakes southward, causing them to carve a gorge across bedrock cuestas, thereby forming the modern incised upper Mississippi River valley. The region has elevations ranging from 603 to 1,719 feet (184 to 524 m) at Blue Mound State Park, and together with the Driftless-like region, covers 24,000 square miles (62,200 km2).

Wisconsin ( (listen)) is a state in the upper Midwestern United States, bordered by Minnesota to the west; Iowa to the southwest; Illinois to the south; Lake Michigan to the east; Michigan to the northeast; and Lake Superior to the north. Wisconsin is the 23rd-largest state by total area and the 20th-most populous. Three of its largest cities are situated on the southwestern shore of Lake Michigan, these include the largest, Milwaukee, as well as Green Bay and Kenosha, the third and fourth most populated Wisconsin cities respectively. The state capital, Madison, is currently the second most populated and fastest growing city in the state. Wisconsin is divided into 72 counties and as of the 2020 census had a population of nearly 5.9 million.Wisconsin's geography is diverse, having been greatly impacted by glaciers during the Ice Age with the exception of the Driftless Area. The Northern Highland and Western Upland along with a part of the Central Plain occupies the western part of the state, with lowlands stretching to the shore of Lake Michigan. Wisconsin is third to Ontario and Michigan in the length of its Great Lakes coastline. The northern portion of the state is home to the Chequamegon-Nicolet National Forest. At the time of European contact the area was inhabited by Algonquian and Siouan nations, and today is home to eleven federally recognized tribes. During the 19th and early 20th centuries many European settlers entered the state, most of whom emigrated from Germany and Scandinavia. Wisconsin remains a center of German American and Scandinavian American culture.The state is one of the nation's leading dairy producers and is known as "America's Dairyland"; it is particularly famous for its cheese. The state is also famous for its beer, particularly and historically in Milwaukee. Its economy is dominated by manufacturing, healthcare, information technology, and agriculture; specifically dairy, cranberries and ginseng. Tourism is also a major contributor to the state's economy. The gross domestic product in 2020 was $348 billion.
