Southwestern Wisconsin, the Driftless Area, was never glaciated; its deep valleys and narrow ridges were formed from millions of years of stream erosion. However, glaciers did cover more than two-thirds of the state at times in the past. The area covered by the last glaciation left examples of glacial landforms seen today.
On April 5 at UW-Barron County, David M. Mickelson will discuss how Wisconsin's landscape came to be what it is today during a talk titled “Wisconsin’s Glacial Landscapes” from noon to 1 p.m. in the Blue Hills Lecture Hall (Ritzinger 234).It is part of the university’s Thursdays @ the U Performance and Lecture Series.
Mickelson is emeritus professor of geoscience, geological engineering and water resources management at UW-Madison, where he has taught since 1971. 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 other 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 2011.
The Thursdays @ the U series is free and open to the public. It is sponsored by the UW-Barron County Foundation. UW-BC is located at 1800 College Dr., Rice Lake. For more information, call the campus at 715-234-8176.
