RT-01-01D From the Introduction: What is the Colorado Geological Survey? The Survey can trace its history to 1872, when Colorado appointed a Territorial Geologist. The state legislature created a Geological Survey in 1907, but it died sometime in the 1920s from fiscal malnutrition. The present Survey was re-established in 1969 and has been involved in every aspect of the state’s geology since then.
