Geologic Map of the Rock Springs 7.5-Minute Quadrangle, Sauk County, Wisconsin

The Rock Springs quadrangle is located in the western Baraboo Hills of south-central Wisconsin. This map, 1:24,000 scale, conveys the rich Precambrian through Quaternary history present on the ground. Here, ancient rocks metamorphosed and folded and were later displaced by a series of faults. Although never glaciated, an ice sheet 8 kilometers to the east dammed the Baraboo River, leaving basins in the map area.
