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 North Freedom quadrangle is located on the South Range of the Baraboo Hills in south-central Wisconsin. The Baraboo Hills are recognized for their ecologic and geologic significance, with superb exposure of Precambrian and Paleozoic rocks and Quaternary sediments. Mapping focused on the Precambrian section, building on past work by subdividing and...

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...

Geologic history and description of Sauk County, the home of Devils Lake and Parfreys Glen. Includes four-color bedrock map and cross sections. Map and cross sections are folded.
