Sauk County Landscape

How did the Wisconsin Dells form? Why is Devils Lake where it is - so high in the landscape? Why is the lower Wisconsin River valley bounded by steep bedrock bluffs? Why are there such wide sand plains along the lower Wisconsin River? Was the ground once deeply and permanently frozen? Did the Wisconsin River once flow toward the east? When and how often have glaciers advanced into the area? Why is there a Driftless Area? Come join a discussion of these questions and many others that will help you understand the geologic history and the origin of the Sauk County Landspace!
