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.
