The Minnesota Geological Survey (MGS) was established in 1872 by the State of Minnesota as part of the University of Minnesota. The MGS serves the people of Minnesota by providing systematic geoscience information to support stewardship of water, land, and mineral resources. MGS geological mapping and research evolve with the progress of science and technology, and the MGS works closely with university, government, industry, and community partners to ensure we respond to the diverse needs of Minnesota.

The UDC site contains a record of all items published by the Minnesota Geological Survey since its inception. Documents, reports, maps and GIS data are available to view or download. GIS data sets are not available for publications prior to 1990 and are very limited before 1994.
