USGS Core Research Center (CRC) Collection of Core


Publication Date


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.

Please email for an appointment to view the materials at the Core Research Center facility in Lakewood Colorado, a suburb west of Denver.


The purpose of the repository is to rescue rock cores threatened with destruction or disposal, process and store them in an efficient manner, and make them available for observation and sampling by all interested parties. The collection contains full-diameter cores, slabbed cores, and well cuttings. Currently, the CRC houses cores from over 9,000 wells representing 1,700,000 feet of core from 33 states and cuttings from 52,000 wells representing 238,000,000 feet of drilling in 27 states. Most of the material is from oil/gas and mineral wells in the Rocky Mountain Region.
