Location data for exploratory, sciencific, or engineering borings conducted statwide since the early 1900s. Drill Core and/or other samples from a large number of these borings are stored in the DNR's Drill Core Library in Hibbing, Minnesota. For more information on the drill core library please vist the DNR's webpage: http://www.dnr.state.mn.us/lands_minerals/dc_library.html

The Minnesota Department of Natural Resources (DNR) completed an inventory of the holdings of the DNR Drill Core Library (DCL). The Drill Core Library facility contains geologic materials including drill core, rotasonic samples, cuttings, pulps and rejects, processed materials, peat, thin sections, thin section billets and hand samples. The inventory project also included identifying space and preservation issues, beginning the process of centralizing and standardizing the administrative databases for all holdings, and making more information within the DCL publicly available.

The Core Research Center (CRC) was established in 1974 by the U.S. Geological Survey (USGS) to preserve valuable rock cores for use by scientists and educators from government, industry, and academia. The cylindrical sections of rock are permanently stored and available for examination and testing at the core storage and research facility in Denver, Colorado. The CRC is currently one of the largest and most heavily used public core repositories in the United States. The CRC encourages use of its facility by all interested parties. Tours of the facility are available by appointment.
