About the Core Research Center

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.

Important Notice Regarding Real ID Act Requirements for Entry to Federal Facilities
As of October 10, 2018, all states and territories are either compliant with the Real ID act or have extensions until 2019. The extension dates vary, ranging from January to October, so please check your state. Compliance status may affect TSA checkpoints or entry to Federal facilities including the Denver Federal Center - home of the CRC. PLEASE NOTE THAT EVEN IF YOUR STATE IS LISTED AS COMPLIANT, IF YOU HAVE AN OLDER LICENSE THAT DOES NOT MEET THE REAL ID ACT CRITERIA, YOU MAY HAVE DIFFICULTY ENTERING THE DENVER FEDERAL CENTER. The Real ID Act was passed by Congress in 2005, based on recommendations from the 9/11 Commission. Please check the DHS website for the latest information on the compliance status of your state. If your ID was issued by a non-compliant or recently compliant state / territory, you might consider acquiring an alternative ID such as a U.S. Passport or U.S. Passport card. More information about the REAL ID Act of 2005, and Secure Driverís Licenses can be found on this page from the Department of Homeland Security:
