Many of the most prominent landscape features of central Wisconsin and the Baraboo and Sauk Prairie region were formed along the western margin of the Green Bay Lobe of the Laurentide Ice Sheet. We will discuss how glacial ice, glacial lakes, permafrost, and meltwater rivers combined to shape the landscape we see today. We will also discuss the results or recent studies that constrain the timing of glacial events in the area.
