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...

The Durwards Glen 7.5-minute quadrangle map is located in Columbia and Sauk counties, southeast of the city of Baraboo. This geologic map includes Precambrian through Quaternary units. New mapping has focused on subdividing the Baraboo Quartzite into four separate members and delineating Quaternary deposits in greater detail than prior work.

The Driftless Area of southwestern Wisconsin and northwestern Illinois got its name from the lack of glacial sediment ("drift") covering the landscape. The surficial geology and topography of the Driftless Area are thus distinct from the surrounding region where multiple phases of glaciation left their mark. This pamphlet, a collaborative effort between...

Elevation contour data and an accompanying report provide an updated interpretation of the elevation of the top of Precambrian bedrock in south-central Wisconsin. The elevation surface was developed from geologic and geophysical data, and provides new detail on the entrenched bedrock valleys that were incised into the north and south ranges of the Baraboo...

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...
