The Dells of the Wisconsin River (used in the singular, and also called the Wisconsin Dells) is a 5 mile gorge on the Wisconsin River in southern Wisconsin in the United States noted for its particular scenic beauty, in particular for its unique sandstone rock formations and tributary canyons. The unique cliffs, some over 100 ft. (30 m) high, and side canyons are closed to the public to protect sensitive ecological features. The viewing of the rock formations by water is a popular tourist attraction in the area. The nearby town of Wisconsin Dells is the center of summer tourist activity, much of it in the form of the theme parks unrelated to the river features. - Wikipedia
