Badger Talk: Geology of the Ice Age Scenic Trail

Join us to hear David Mickelson speak about the Geology of the Ice Age National Scenic Trail.

Southwestern Wisconsin, the Driftless Area, was never glaciated and its deep valleys and narrow ridges result from millions of years of stream erosion. About 25,000 years ago glaciers covered more than two thirds of what is now Wisconsin, creating the glacial landforms we see today. The 1,000-mile trail across Wisconsin highlights many of these Ice Age features.

This talk will explain the formation of moraines, kettles, outwash plains, drumlins, eskers, and tunnel channels using slides of modern glaciers as well as many photos and maps from Wisconsin. https://www.fitchburgwi.gov/calendar.aspx?EID=20481
