The Area

This area is called The Driftless because it lacks glacial drift, which refers to the deposits of silt, gravel and rock that glaciers would have left behind had they passed through this part of Southwestern Wisconsin. The area is unique in that the land here was never flattened by the ice that came through most of the Midwest during the last glacial period/ice age. When glaciers were in surrounding areas, the melt-water sometimes made its way into the Driftless Area and contributed to the formation of the valleys and bluffs which characterize the landscape, which is known for steep hills, forested ridges, deeply carved river valleys, and karst geology with caves and spring-fed 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.
