Bedrock Geology of Dodge County, Wisconsin

Dodge County lies in southeast Wisconsin, an area almost entirely covered by glacial deposits. This map interprets the distribution of the buried bedrock units across the county. Geologist Esther Stewart’s refinement of the bedrock elevation contours may help land-use planners identify areas most susceptible to groundwater contamination from applications of nutrients and pesticides, and identification of subtle folds in the Paleozoic units may help predict local changes in the physical properties of the bedrock. Includes map, 7-page report, and data files.
