Speaker: Dr. Dave Ullman, Assistant Professor of Geoscience, at Northland College

Since the end of the most recent glaciation has been a period of dramatic change of the upper Midwest. What are now the rolling hills and scattered lakes of a gentle Midwestern landscape were once covered in a blanket of flowing and grinding ice, sculpting the underlying terrain and leaving behind many telltale markers of a changing climate. The Laurentide Ice Sheet scoured and deepened the Lake Superior basin creating the depths we see today. However, as ice retreated, Lake Superior took on many forms depending on whether glacial ice dammed the eastern drainage outlet at Sault Saint Marie.

This talk will review the recent data explaining the timing of glacial ice surrounding Lake Superior and the implications for past shorelines.
