Description:
This service is NOT for download but may be viewed in web maps and apps.Georeferenced Statewide Bedrock Geologic Map of Wisconsin, 1982. The Statewide Bedrock Geologic Map of Wisconsin was developed to provide a reliable, accurate and detailed representation of the state’s subsurface geology. It supports a variety of applications, including geological research, land-use planning, resource management, environmental conservation, education, public outreach, and policy development. By offering insights into the composition, structure, and distribution of bedrock formations, the map aids in identifying potential geological hazards and areas of scientific or ecological significance and helps planners, researchers, and decision-makers make informed choices. The statewide geologic map symbol for each formation is standardized for consistency and can be found in the accompanying legend. The legend provides essential information, including formation names, lithologic descriptions, geologic age, and the symbology used in the dataset. This map and its data were developed by UW Extension-Geologic and Natural History Survey (WGNHS), Meredith E. Ostrom. Visit WGNHS Maps & Publications search for WGNHS maps and contact WGNHS at info@wgnhs.wisc.edu with any questions about this map or data. The map was georeferenced for use in this service by the Wisconsin DNR Bureau of Drinking Water and Groundwater, Water Use Section.  For any questions contact the Bureau of Drinking Water and Groundwater GIS Analyst at DNRDGGISAPPS@wisconsin.gov. This data was mapped at a very small scale (ranging from 1:5,000,000 to 1:500,000), making it unsuitable for detailed local analysis or site-specific decision-making. Users are advised to consult local or higher-resolution datasets when conducting detailed analyses or making critical decisions.
