Temporary Closure in Response to Coronavirus COVID-19 -- Valid for the week of August 2nd, 2021.

Following guidelines from the CDC and the Department of the Interior Office of Emergency Management, the USGS Core Research Center is temporarily closed to visitors as our employees transition to telework. We will work with you to reschedule your visit once we resume normal operations. Updates will be posted to this website.

Please contact us via email (crc@usgs.gov) which will be monitored during normal business hours.  The CRC staff does not have access to office phones while teleworking and will not be able to respond to calls or voicemail messages.

 

The CRC's extensive rock core and cuttings collection is available for study by interested parties by appointment only. Contact us at CRC@USGS.GOV or (303) 202-4851 to schedule an appointment. Please review our FAQs for help in planning your visit.

The Core Research Center is home to 9,800 rock cores and 53,000 cuttings wells that since 1974 has supplied valuable scientific information to academia, government agencies, and industry alike.  The majority of research conducted on the collection to date has been related to natural resource characterization, but the collection has also been studied for many other lines of inquiry. Some examples of past research include a core drilled from Cajon Pass, CA which was drilled to determine fault motions and resistance to plate motion from two plates along an important fault.  Cores from the Enewetak Atoll were originally used to understand the effects of nuclear bursts on geologic structures but have more recently been used in climate studies.  Cores that were drilled in Yellowstone from a 1967-1968 expedition are still being researched to understand the chemistry of the rocks and the interactions with the geothermal fluids of Yellowstone.  Cores from the Green River Formation have been used to understand ancient lake systems and the Paleocene-Eocene Thermal Maximum.  The Castle Pines and Kiowa cores have been used to examine spatial variation on yields for groundwater resources in the Denver Basin and to study the paleobiology of the Upper Cretaceous and Lower Tertiary of the Denver Basin. These are but a few examples of how these valuable resources can continue to contribute to our understanding of earth systems.

 

Important Notice Regarding Real ID Act Requirements for Entry to Federal Facilities

As of April 30, 2021, all states and territories are issuing IDs that are compliant with the Real ID act. A compliant ID must be presented at TSA checkpoints or for 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.  Full enforcement of REAL ID begins May 3, 2023, travelers without a compliant or enhanced ID (or other acceptable ID) will not be allowed to fly.  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 and how to tell if your ID qualifies. If your ID is not compliant, 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 Driver’s Licenses can be found on this page from the Department of Homeland Security:

Core handling, transportation and processing for the South Pole ice core (SPICEcore) project

An intermediate-depth (1751 m) ice core was drilled at the South Pole between 2014 and 2016 using the newly designed US Intermediate Depth Drill. The South Pole ice core is the highest-resolution interior East Antarctic ice core record that extends into the glacial period. The methods used at the South Pole to handle and log the drilled ice, the...
