Geology of the Baraboo Hills, Sauk and Columbia Counties, Wisconsin
Located in the south-central portion of the state, new geologic mapping of the frequently-visited Baraboo Hills has resulted in a revision of the stratigraphy of the Precambrian-aged bedrock. The Baraboo Quartzite is now divided into four informal members, and the maximum depositional age for the Baraboo Quartzite is 1714±17 million years old. These...-

This report describes regionally extensive aquifers and presents several extensive datasets collected from deep wells across the county. The report also documents the construction and... -
Quaternary Geology of Columbia, Green Lake, and Marquette Counties, Wisconsin
Columbia, Green Lake, and Marquette Counties were glaciated during the last ice age, and large areas were inundated with water from proglacial lakes and large meltwater rivers that occupied the valleys of the existing Wisconsin and Fox Rivers. These processes resulted in rolling upland hills, including drumlins punctuated by low-lying areas dominated by...-
