Emeritus Faculty members Gordon Medaris, Bob Dott, and Dave Mickelson gave a special Weeks Lecture on Wisconsin Geology last Friday, November 22nd.
Wisconsin lies in the midst of the North American continent. It has no tall mountains, volcanoes, ocean shores, or glaciers today, but all of these existed at various times in the region’s past. We can read the history of Wisconsin in its rocks and soils, which bear witness to eons of deep intrusions, rifts, volcanic eruptions, flooding by the sea and deposition of sandstone and carbonate rocks, erosion over tens of millions of years, glaciation, and other events that shaped the land.
