Quaternary Geology of Richland County, Wisconsin
The topography of the Driftless Area, which was never glaciated during the Quaternary Period, is dominated by fluvial incision into flat-lying Paleozoic bedrock, resulting in deep, dendritic valleys. Local relief reaches 115 meters. Sediment coring across the region reveals that the geology of unconsolidated surficial materials is often controlled by the...-

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...-

Geologic Map of the Ferryville and Lansing 7.5-Minute Quadrangles, Crawford County, Wisconsin
The geologic map of the Ferryville and Lansing 7.5-minute quadrangles (Crawford County), located in the Driftless Area of southwestern Wisconsin, provides new observations and lithologic descriptions of the area's geology. This work supports the Wisconsin Department of Transportation's ongoing efforts to mitigate slope failures along the Wisconsin State...-

Bedrock Geology of Grant County, Wisconsin
Three-dimensional bedrock mapping of Grant County at a scale of 1:100,000 provides new baseline information on the distribution of geologic units. Grant County contains Paleozoic bedrock units ranging in age from Silurian to Cambrian. Gentle folds and small faults deform the Paleozoic sequence and were mapped based on structure contours of the base of the...-

Quaternary Geology of Wisconsin
This 1:500,000 scale map of Wisconsin depicts sediment deposited by glaciers, streams, wind, and other processes during the Quaternary Period (2.58 million years ago to present). The map was made by compiling detailed Quaternary mapping and lithostratigraphic studies previously conducted by the WGNHS to generate consistent statewide Quaternary map units....-
