Updated version of Depth to Silurian Bedrock in Eastern Wisconsin
Silurian-aged bedrock in eastern Wisconsin is shallow, fractured, and contains groundwater that is susceptible to surface water contamination. Revisions to Wisconsin state rules ATCP50 and NR151 to regulate manure spreading over this Silurian-aged bedrock create …
Bedrock Geology of Lafayette County, Wisconsin
Located primarily in the Driftless Area of southwest Wisconsin, Lafayette County is underlain by Paleozoic-aged bedrock, primarily siliciclastic and carbonate sedimentary units. These sedimentary rocks were mildly deformed during the Paleozoic, with fold amplitudes and …
Elevation Rasters of Geologic Contacts, Southwest Wisconsin
Elevation rasters (surfaces) were constructed for the base contacts of seven Paleozoic sedimentary lithostratigraphic groups in southwest Wisconsin. Meant to be used at a regional scale of 1:250,000, these surfaces were constructed to provide baseline …
Depth to Bedrock and Raster Elevation Surfaces of the Sinnipee and Ancell Groups, Jefferson County, Wisconsin
Located in southeast Wisconsin, Jefferson County is almost entirely blanketed by sediments that were delivered or shaped by the ice sheet that covered this area during the last ice age. Recent mapping interprets the distribution …
Geologic Map of the Weston and Menomonie South 7.5-Minute Quadrangles, Dunn County, Wisconsin
The 1:24,000-scale geologic map of the Weston and Menomonie South quadrangles is part of a larger project to map all of Dunn County. Prior mapping work in the area was regional in extent (1:250,000-scale), so this …
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, …
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 …
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. …
The Economics of State Geological Surveys
August 22, 2025 Mel Reusche, WGNHS Communications and Outreach Specialist How do we measure the impact of a map? A new study concludes that by investing in state geological surveys, we invest in our future. …
