Dells of the Wisconsin River

Wisconsin Dells is a tourist town that got its name due to the bizarre rock formations on a stretch of the Wisconsin River, the Dells. At the end of the last ice age, melting ice and snow transformed the limestone in the substrate into uniquely shaped mounds and hollows. Native Americans sheltered here and they are now filled with animals. Currently it is a protected natural area and a tourist attraction operated from the nearby city. There are many tours that allow you to visit some of the Dells (which extend for about 8 km) and enjoy the beautiful landscape. In this long stretch, there are steep cliffs on either side of the river and the Dells seemed to form canyons and inlets.
