WISCONSIN DELLS

Wisconsin Dells, Columbia and Sauk Counties. August, 1966. Altitude 7,500 ft. This view to the NNE reveals the city of Wisconsin Dells at right center, a portion of the Lower Dells of the Wisconsin River at lower right, and the Upper Dells at upper center. Highway 13 angles across the upper right. The Upper Dells, a narrow gorge as little as 100 feet in width in places, was created when the waters of Glacial Lake Wisconsin cut a new channel through weak Cambrian Sandstone here about 14,000 years ago as it emptied southwestward into the lower Wisconsin and Mississippi Rivers. The communities of Wisconsin Dells and adjacent Lake Delton (lower left) appear relatively undeveloped in this 1966 photograph, but today numerous amusement parks and recreational businesses make it the prime tourist- oriented locale in Wisconsin.
