Entrance to the CRC on the Denver Federal Center
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 for residents of AMERICAN SAMOA, ARIZONA, IDAHO, LOUISIANA, MAINE, MINNESOTA, NEW HAMPSHIRE, NEW YORK, OKLAHOMA, AND WASHINGTON (state).
We have recently learned that Driver’s Licenses issued by these states are not “REAL ID compliant” and therefore will no longer be accepted for entry to Federal facilities including the Denver Federal Center - home of the CRC. The Real ID Act was passed by Congress in 2005, based on recommendations from the 9/11 Commission. The CRC is waiting for more information on enforcement of the deadline as it applies to our facility, but it is likely to occur in late 2015. If your ID is issued by one of the non-compliant states, please bring an alternative ID such as a U.S. Passport, U.S. Passport card, unexpired Federal employee badge, or a military identification card. More information about the REAL ID Act of 2005, and Secure Driver’s Licenses can be found on this page from the Department of Homeland Security: http://www.dhs.gov/secure-drivers-licenses
The CRC apologizes for any inconvenience to our visitors.
