Over the Labor Day week-end we made a trip to Plover,Wisconsin, the home of our niece Rachel and husband Ben and daughter Eliza. Also visiting them were Rachel's parents Marcus and Heidi, as well as her brother Adam and his wife Kjerstin with their son Kai.. Our travels are certainly wonderfully enhanced by family gatherings! Technically I was done with writing about southwestern Wisconsin. Devil's Lake is north of Spring Green, about 20 miles south of the Wisconsin Dells. As I had written before, the southwestern section of the state is called the Driftless region. In contrast to that area, Devil's Lake is glaciated. It was formed many years ago when the Wisconsin glacier invaded hills from the east, and impounded an ancient river. As the ice melted it left a mass of rock and sand (moraines) at both ends of a gorge, damming the river and creating Devil's Lake. That is about as simple as I can make it! The park has within its boundaries parts of the Ice Age National Trail, so we were pleasantly surprised when we discovered that we did not have to pay the state fee for entering the park because we had a national park pass.
