The Driftless Area: The extent of unglaciated and similar terrains in Wisconsin, Illinois, Iowa, and Minnesota
The Driftless Area of southwestern Wisconsin and northwestern Illinois got its name from the lack of glacial sediment ("drift") covering the landscape. The surficial geology and topography of the Driftless Area are thus distinct from the surrounding region where multiple phases of glaciation left their mark. This pamphlet, a collaborative effort between...-
