Quaternary Geology of Fond du Lac County, Wisconsin
The Quaternary geology of Fond du Lac County consists of glacial deposits and landforms dating to the last part of the Wisconsin Glaciation (ca. 20,000 to 12,000 yr BP) and nonglacial deposits and landforms of Holocene age (11,700 yr BP to present). Glacial till and meltwater sediment were deposited by the Green Bay and Lake Michigan Lobes of the...-

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... -
Quaternary Geology of Columbia, Green Lake, and Marquette Counties, Wisconsin
Columbia, Green Lake, and Marquette Counties were glaciated during the last ice age, and large areas were inundated with water from proglacial lakes and large meltwater rivers that occupied the valleys of the existing Wisconsin and Fox Rivers. These processes resulted in rolling upland hills, including drumlins punctuated by low-lying areas dominated by...-

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...-

Potential Effects of Climate Change on Stream Temperature in the Marengo River Headwaters
Cold-water trout habitat in Wisconsin is projected to substantially decrease as a result of climate change. The extent of habitat loss depends, in part, on groundwater discharge to streams, which can provide cool-water refuges for trout. Survey hydrogeologists used field measurements and models of groundwater flow and stream temperature to evaluate how...-

Water-Quality Indicators of Human Impacts to the Wetlands of Door County, Wisconsin
Door County, the narrow peninsula in eastern Wisconsin, is home to numerous wetlands, many of which are fed by groundwater. Poor-quality groundwater discharging to a wetland can alter the ecology of the wetland and harm native plant and animal communities. This report documents a one-year study of six wetlands. Researchers recorded water quality and... -
