Colorado Geological Survey

The Colorado Geological Survey (CGS) is the primary geoscience agency of the U.S. State of Colorado. The headquarters of the CGS are located at the Colorado School of Mines in Golden, Colorado.

Mission
The mission of the CGS is to build a vibrant Colorado economy and sustainable communities, free from geologic hazards, for people of Colorado to live, work and play through good science, collaboration, and sound management of mineral, energy, and water resources.

History
Until 1907, Colorado had no state geological survey, but a series of geologists held the position of Territorial Geologist, a part-time unpaid position. The Colorado Geological Survey was established by the Legislature in 1907, along with the position of State Geologist who was also the Director of the Survey. The first geological survey mysteriously went out of existence sometime during, or after, 1925. The Colorado Geological Survey was re-established in 1967 and continues to provide sound science and service to the citizens of Colorado.
