Applications of the Columbia County, Wisconsin, Groundwater-Flow Model
Computerized groundwater-flow models provide scientific analysis of water resources. Since its initial development in 2014, the Columbia County groundwater-flow model has been used to respond to requests for information about specific groundwater and land use issues. This companion report to the Hydrogeology and simulation of groundwater flow in Columbia... -
Mineral Assessments for Conservation Easements in Wisconsin
If you’re thinking about donating land as a conservation easement but don’t own the subsurface (known as “severed mineral rights”), then you’ll need an assessment of the land’s mineral potential to determine whether the easement will qualify as a charitable tax deduction. Geologists at the Wisconsin Geological and Natural History Survey perform this... -
Depth-to-Bedrock Mapping in Wisconsin
Depth-to-bedrock maps show the thickness of unconsolidated materials overlying bedrock. These maps provide a key link between the underlying geology, groundwater flow, and land use and are important in guiding activities such as permitting, bridge construction, and the land application of waste products in sensitive areas. Given their role in guiding... -
Depth-to-Bedrock Map of Dodge County, Wisconsin
This map shows thicknesses of deposits of unconsolidated materials above the bedrock. Across the county, depth to bedrock ranges from 0 feet, where bedrock is exposed, to over 250 feet within bedrock valleys. Areas with bedrock depths shallower than 20 feet are of particular importance for land-use planning and to the construction stone industry. Such... -
Florence Iron Mine: Historical Maps Showing Location of Surface Development, Regional Setting, and Underground Workings
From 1880 to 1931, an extensive iron mine operated near the city of Florence in northeast Wisconsin. These 21 maps from its middle years of operation are the only surviving records of what exists below the surface. These maps are of historical interest for their record of surface features that are no longer in existence. They may also have potential...-

Geologic Map of the Baraboo 7.5-Minute Quadrangle, Sauk County, Wisconsin
The Baraboo quadrangle, records where glaciers stopped in the east-central Baraboo Hills. On this map, 1:24,000 scale, Precambrian igneous and metasedimentary rocks are overlain by Paleozoic sedimentary rocks and, more recently, by glacial deposits. Superb exposures of all three can be found in Devils Lake State Park and Parfreys Glen State Natural Area.-

Geologic Map of the Rock Springs 7.5-Minute Quadrangle, Sauk County, Wisconsin
The Rock Springs quadrangle is located in the western Baraboo Hills of south-central Wisconsin. This map, 1:24,000 scale, conveys the rich Precambrian through Quaternary history present on the ground. Here, ancient rocks metamorphosed and folded and were later displaced by a series of faults. Although never glaciated, an ice sheet 8 kilometers to the east...-
