context_page_description: The Core Research Center is a facility run by the United States Geological Survey, located in "F" bay in building 810 on the Denver Federal Center campus. It is maintained by the USGS to preserve valuable rock cores, well cuttings and various other geologic samples for use by scientists and educators from government, industry and academia. The CRC is open to the general public for core viewings or tours of the facility by appointment only. The CRC houses the largest collection of rock cores and well cuttings in the nation.
context_section_description: Archived Cores have been slabbed, which means that it has been cut lengthwise, with a rock saw, which exposes a fresh flat surface to enhance the core viewing process. This also enables the cores to boxed and stored like books on a shelf, which allows for quick access to specific depth intervals.
