Title: What is Driftless Area? Explain Driftless Area, Define Driftless Area, Meaning of Driftless Area
Created on: 2019-04-01

Description: The Driftless Area is a region in southeastern Minnesota, southwestern Wisconsin, northeastern Iowa, and the extreme northwestern corner of Illinois, of the American Midwest. The region escaped glaciation during the last ice age and, consequently, is characterized by steep, forested ridges, deeply-carved river valleys, and karst geology characterized by spring-fed waterfalls and cold-water trout streams. Ecologically, the flora and fauna of the Driftless Area are more closely related to those of the Great Lakes region and New England rather than those of the broader Midwest and central Plains regions. Colloquially, the term includes the incised Paleozoic Plateau of southeastern Minnesota and northeastern Iowa. The region includes elevations ranging from 603 to 1,719 feet at Blue Mound State Park and covers an area of 24,000 square miles . The rugged terrain is due both to the lack of glacial deposits, or drift, and to the incision of the upper Mississippi River and its tributaries into bedrock. An alternative, less restrictive definition of the Driftless Area includes the sand Plains region located northeast of Wisconsin's portion of the incised Paleozoic Plateau in the southwestern part of the state. This portion of the Driftless Area in the southwestern section of Wisconsin's Central Plain also lacks evidence of glaciation , and contains many isolated Hills, Bluffs, Mesas, Buttes, and Pinnacles that are outlying eroded Cambrian bedrock remnants of the plateau to the southwest.
