1. The Geology and Landforms of Wisconsin’s Driftless Area Cameron Brooks-Miller

2. The Driftless Area Deeply cut river valleys Karst topography Dramatic bedrock uplands Undisrupted erosion and deposition Absence of glaciation Drift is a generic term for any sediments of glacial origin – whether till or outwash or ICSD. Why? How? Where?

3. The Paleozoic Plateau ● Extending within the boundary of southwestern Wisconsin, northwestern Illinois, northeastern Iowa and a portion of southeastern Minnesota ● Topographically elevated region of Paleozoic sedimentary rock the surrounds the Driftless Area. ● The Driftless Area lies within this region.

4. Bedrock Geology Sandstone Limestone Karst Environments Deeply incised river valleys and dramatic bluffs. Valleys have hundreds of meters of Quaternary deposits.
