This is a free, in-person event hosted by Kettle Moraine State Forest – Southern Unit on October 18, 2025 at 12:30 PM. This event will celebrate the Wisconsin Science Festival and the Ice Age Trail Mammoth Hike Challenge. No registration is necessary to attend. With questions, please call the Forest headquarters at 262-594-6200. This event is a part of the Wisconsin Science Festival!
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 1000-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.
David M. Mickelson is Emeritus Professor of Geoscience, Geological Engineering, and Water Resources Management at UW–Madison and has taught glacial geology, intro geomorphology, coastal geomorphology, air photo interpretation and Geology of the National Parks at Wisconsin since 1971. Geomorphology is the study of earth surface processes. One area of his research includes glacial geology. He has done research on modern glaciers and glacial deposits in Sweden, Norway, Argentina, China, Alaska, the Rocky Mountains, New England, and the Midwest. His continuing research interest has been the glacial deposits and the glacial history of Wisconsin. His other main area of research is shoreline erosion and nearshore and beach processes. He has published numerous papers on shore processes on the Great Lakes and on Wisconsin glaciation. He has served on the Board of Directors of the Ice Age Trail Alliance since 2010. He is the first author of the book “Geology of the Ice Age National Scenic Trail” published by the University of Wisconsin Press in late 2011.
