CGS Publications

CGS publications feature a wide range of geoscience reports, maps, and digital GIS data from all corners of Colorado

Much of the CGS website is under heavy re-construction and will be for some time. The Publications area is working normally, but there is a lot of content from our original site that was in desperate need of updating. Please bear with us as we gather new information and rewrite hundreds of pages of material, gather and properly caption high-resolution images and otherwise bring you some very cool new and archival material never before seen! Stay in touch by subscribing to the >RockTalk< blog where we will announce new items periodically.

Since the first CGS Bulletin A Preliminary Report on the Geology of the Monarch Mining District, Chafee County in 1910, the Survey has issued more than eight hundred professional reports, publications, maps, and datasets concerning the geology, groundwater hydrology, mining, energy production, and geologic hazards around the state of Colorado.
