The Wisconsin Geological and Natural History Survey (WGNHS) was created by the Wisconsin Legislature in 1897. It is the descendant of earlier state surveys in Wisconsin, which date back to 1854.
The Wisconsin Geological and Natural History Survey (WGNHS), a part of the University of Wisconsin–Extension, conducts earth-science surveys, field studies, and research. We provide objective scientific information about the geology, mineral resources, water resources, soil, and biology of Wisconsin. We collect, interpret, disseminate, and archive natural resource information. We communicate the results of our activities through publications, technical talks, and responses to inquiries from the public. These activities support informed decision making by government, industry, business, and individual citizens of Wisconsin.
If you have questions or need information or help on geology, minerals and mining, hydrogeology, groundwater, soils, or topographic maps, staff of the the WGNHS can very likely be of service to you. Our listing of areas of expertise and contact persons may direct you to a specific person, or you may email your questions about Wisconsin geology to firstname.lastname@example.org. (Please type "WGNHS" in the subject line of your note.) For information about publications, contact the Map Sales Office, 608/263.7389, or email email@example.com. Office hours are 8:00 AM to 4:30 PM, Monday through Friday.
