Welcome to the Minnesota Geological Survey

The Minnesota Geological Survey is a research and service arm of the Newton Horace Winchell School of Earth and Environmental Sciences at the University of Minnesota. It investigates the geology of Minnesota and provides basic public information on the geology of the state. The Survey works with state, county, and regional offices to set up geologic databases and provide technical guidance for water-resource planning, land management and mineral exploration policy, energy system development, and other planning and resource management activities.
