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, …
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 …
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. …
Geologic Map of the Eastman and Harpers Ferry 7.5-Minute Quadrangles, Crawford County, Wisconsin
The geologic map of the Eastman and Harpers Ferry 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 …
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 …
