Geology of the Minnesota River

How was the Minnesota River Valley formed?  This is an interesting story featuring glaciers, the formation of a glacial lake and the bursting of a dam-like structure and a wall of water pushing across what is now southern Minnesota.  We will take a hike at Minneopa State Park to get a better view of what happened here thousands of years ago and some of the different rock formations.  Part of the geological story at Minneopa of course has to do with the creek’s gorge and falls.  Meet at the Group Campground on the campground side of the park.
