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...

Series of 43 page-size maps showing the chronology of the last glaciation's advances and retreats across Wisconsin. Includes a brief discussion about how the maps were made, how lake positions were determined, as well as a list of selected references.

Explains the geologic causes of the county’s natural landscape and follows each description with an exploration of the parts of the county that showcase specific geologic features. Includes a folded color map that shows the surface geology and locations of parks. Heavily illustrated.

Brief technical description of Wisconsin’s geologic history, glacial phases and lobes, and correlation and distribution of Pleistocene units. Heavily illustrated.

Devils Lake State Park is a place of striking geologic contrasts, where some of the oldest rock exposed in southern Wisconsin lies next to some of the youngest geologic materials in the state. The purple rock (called Baraboo quartzite) in the walls of Devils Lake gorge is more than 1.7 billion years old; the glacially deposited ridges that block both ends...
