DNR Drill Core Library
The Minnesota Department of Natural Resources, Lands and Minerals Division, maintains a Drill Core Library in Hibbing, Minnesota. It serves as the State of Minnesota's repository for archiving bedrock and earthen material core samples collected during minerals exploration, engineering, and geoscience research programs across the state. A new web page and interactive web map greatly facilitates public access to the more than three million linear feet of drill core and other geologic materials archived within the DNR Drill Core Library in Hibbing. The webpage outlines the Library’s mission and provides details for those interesting in viewing, sampling, and/or submitting drill core materials. An associated interactive web map displays more than 8,500 source locations for the material archived within the Drill Core Library, with links to drilling information. This user-driven map interface allows anyone with internet access to compare locations against overlays of geologic information and state mineral leases. This kind of interactive manipulation of drill hole and geologic data previously required ArcGIS software. Learn more »
