Wisconsin Geological and Natural History Survey

The Wisconsin Geological and Natural History Survey (WGNHS) is a state organization that studies Wisconsin's geology, natural resources, and environment. It examines rocks, minerals, water, and soil to understand the state's natural features and how they affect land use, safety, and conservation. WGNHS provides scientific data, maps, and insights to help landowners, policymakers, educators, and the public make informed decisions about natural resource management, environmental protection, and land development. Its work supports sustainable growth and helps protect Wisconsin’s natural landscape and resources for future generations.
