Driftless Area

Driftless Area,

c.13,000 sq mi (33,670 sq km), largely in SW Wis. but extending into SE Minn., NE Iowa, and NW Ill. The continental glacier which covered most surrounding regions did not touch this area, which abounds in caves and sinkholes and has residual, well-drained soil. Because it was an important lead-mining region, the federal government prohibited farming in the Driftless Area until the 1840s. It was then settled by European immigrants.

However, the contribution of pollutant loads to streams could be significant because about 80 percent of the base flow in many streams in the Driftless Area Ecoregion is derived from springs and seeps (Troelstrup and Perry, 1989).

The paleoecology of Iowa, southern Wisconsin, and Illinois is important in understanding paleoenvironments of the Midwest because (1) many taxa that were forced south during glaciation moved through these regions to their present position following deglaciation; (2) the paleoecology of the Driftless Area south into much of Illinois and eastern Iowa is poorly known; and (3) the axis of the "Prairie Peninsula" (Transeau 1935) runs through this region.
