The Baraboo Range is a horseshoe-shaped ridge of Precambrian quartzite in south central Wisconsin, its rock formed from sediment deposited in a shallow sea some 1.7 billion years ago before being metamorphosed, folded into a syncline and uplifted, then left standing as far younger surrounding rock eroded away around it over an immense span of geologic time. The range extends about 25 miles across Columbia and Sauk counties, with the city of Baraboo sitting in its central valley, and its eastern half was overridden by the last continental ice sheet while its unglaciated western half marks the edge of Wisconsin's Driftless Area. It was designated a National Natural Landmark in 1980.
