2025 Year in Review
Director’s message In the last year, WGNHS published new and updated maps from some of Wisconsin’s most famous geologic regions, including the Baraboo Range and the Driftless Area. We also published the first statewide bedrock topography compilation in over 50 …
Hydrogeologic Atlas of Burnett County, Wisconsin
This hydrogeologic atlas offers a comprehensive interpretation and analysis of groundwater resources across Burnett County, Wisconsin. It encompasses assessments of the water-table elevation and groundwater flow directions, depth to the water table, depth to bedrock, …
Wisconsin Bedrock Topography, 100-Meter Resolution
This is the first statewide depth to bedrock (bedrock topography) compilation since the statewide map Depth to Bedrock in Wisconsin(link) by Trotta and Cotter in 1973. WGNHS GIS Specialist Matthew Rehwald used modern GIS …
Quaternary Geology of Vernon, Crawford, and Richland counties, 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 …
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 …
Wisconsin Groundwater-Level Monitoring Network Improvements, 2022-2024
This report documents work completed as part of a grant from the U.S. Geological Survey’s National Groundwater Monitoring Network (NGWMN) program. It provides an overview of the Wisconsin Groundwater-Level Monitoring Network (WGLMN) and provides detailed …
Depth to Bedrock in Lafayette County, Wisconsin
The depth-to-bedrock raster of Lafayette County is a continuous model of surficial sediment thickness with a cell size resolution of 32.8 ft (10 m). Results show that the depth to bedrock in Lafayette County varies …
Depth to Bedrock in Grant County, Wisconsin
Depth-to-bedrock mapping of Grant County provides baseline information on unconsolidated surficial sediment thickness across the county. Bedrock aquifers in Grant County are susceptible to contamination from various land use activities, and depth to bedrock represents …
Building Up Baraboo: A New Geologic Map of the Baraboo Hills
Mel Reusche, WGNHS Communications and outreach specialist Devil’s Lake State Park is one of many geologic marvels dotted around the oval-shaped footprint of the Baraboo Range that are explored by millions of visitors each year. …
