History of the Survey

History of the Survey

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 CGS 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 CGS was then re-established in 1967 and continues to provide sound science and service to the citizens of Colorado.
