David Mickelson: Southern Wisconsin Glacial Landscapes

Southwestern Wisconsin, the Driftless Area, was never glaciated, and its deep valleys and narrow ridges result from millions of years of stream erosion. At times in the past, glaciers have covered more than two-thirds of Wisconsin, and the area covered by the last glaciation exhibits excellent examples of glacial topography. Wisconsin was chosen as the location of the Ice Age National Scenic Trail and the Ice Age National Scientific Reserve mostly for that reason. Our most recent glaciation was the Wisconsin glaciation, and it was responsible for many of the glacial landforms we see today.
