Research at the CGS takes many forms and we collaborate with many municipal, county, state, and national partners. The following information and links are regularly updated as our projects develop, expand, and our research is published.
With a mission that is driven by state mandate — to inform the citizens of Colorado regarding a variety of geoscience and geo-engineering issues — the CGS tackles a wide range of basic field research around the state. The results are generally public-domain and available for download at our bookstore. In addition, contemporary research projects typically result in GIS data packages that are easily integrated within third-party GIS mapping solutions.
As the Survey has been around more than one hundred years, we also have an extensive archive of research publications that may be of interest. Most of these are available as free PDF downloads through our bookstore.
Current Research Areas
Research into the many geo-hazard sources in the state is constant and ongoing, and represents a major information source for anyone with an interest in this critical subject. For more information contact: Jill Carlson
- Debris Flow Susceptibility Mapping
- Debris Flow Susceptibility of Boulder County
- Debris Flow Susceptibility Map of Larimer County, Colorado
- Landslide Inventory and Susceptibility Mapping
- Geologic Hazard Derivative Maps
- Quaternary Fault Update
- Statewide Seismic Network
The flooding events of September 2013 underscored the need for a statewide, county by county assessment of potential debris flow susceptibility zones. This project will include new debris flow mapping and modeling and discussion of active mitigation techniques. Results will be available at the Colorado Hazard Mapping and Risk MAP Portal. Two completed county maps are already available:
A continuation of landslide susceptibility mapping already taking place in El Paso, Douglas and Jefferson counties, this project will expand to Mesa County once the three counties are complete and when LiDAR is delivered in late 2016. Landslides mapped using LiDAR and stereo imagery will be added to the CGS statewide inventory map.
The CGS generates extensive derivative data and interpretive mapping information based on existing 1:24K Statemap Quads.
The USGS hosts the Colorado results of this ongoing national research project in the extensive Quaternary Fault and Fold Database of the United States. The CGS will be updating the USGS maps with new fault traces and paleoseismological investigations in late 2017. Earlier data is found on the Colorado Late Cenozoic Fault and Fold Map Server.
The CGS is augmenting other CO-based seismometer networks with several installations, the first one along the Front Range is operational and active in the Incorporated Research Institutions for Seismology (IRIS) network.
Mapping the complex geological features of the state is an important aspect of the CGS portfolio. The results of extensive field work during summers are brought back into the office and laboratory in the process of creating detailed geologic maps for a variety of applications. These maps help support many CGS projects as well as Federal, State, and local government and private industry. For more information contact: Matt Morgan
- National Cooperative Geologic Mapping Program: STATEMAP Component
Collaborative geologic mapping of 1:24,000-scale quad maps is an ongoing process with a number of new maps produced each year. There are eight in review as of the beginning of 2017, and following are a few of the most recent published:
Hydrogeology / Groundwater
The CGS conducts research on how geology affects and controls the water resources within Colorado. This includes the study of the geologic framework for groundwater and its occurrence, movement, and quality. We also investigate natural or ‘background’ conditions of water quality, identifying the effects of water-rock interactions on surface-water and groundwater.

- Geology and Groundwater Resources of Chaffee County (January 2017)
- Geology and Groundwater Resources of Mesa County (late 2017)
- Lower Arkansas Basin Uranium (LABU)
- Gilcrest-LaSalle Hydrogeologic Characterization Report
This ongoing research work is proceeding county-by-county in collaboration with the Colorado Water Conservation Board (CWCB) in select areas. Each county project weaves together extensive background data and field research specific to the groundwater issues of the area.
A collaborative investigation with CSU of geologic uranium sources in the Basin and of land use practices that may affect the transport of uranium from its sources to the Arkansas River. (Documentation to come)
The Gilcrest/LaSalle project evaluated high groundwater conditions in the South Platte alluvial aquifer near Gilcrest and LaSalle, Colorado — conditions that were directly impacting local homes. The integration of previous investigations along with new analysis added significantly to the Study Area hydrogeologic characterization, and provided insight into the South Platte alluvial aquifer depositional model, particularly with respect to discontinuous low permeability beds within the central portion of the alluvial aquifer, and lower permeability beds on the aquifer flanks.
The CGS has always been closely involved in the development of state-wide mineral resources. Current research projects utilize fresh data as well as historical records to construct valuable derivative maps and reports on the many mineral resources around the state. For more information contact: Matt Morgan
- Statewide Proppant Sand Study
- Mineral Resource Derivative Maps
- Colorado Mineral and Energy Industry Activities
The primary objective of this statewide project is to determine the geological potential for natural proppant or ‘frac’ sands. It will include evaluating both Paleozoic, Mesozoic, and Tertiary sandstone formations, extensive Quaternary eolian deposits, and localized eolian sand and alluvial/fluvial deposits throughout the state. A secondary objective is to characterize potential silica sand sources for other uses. (Documentation to come)
Derivative maps are generalizations of detailed geological information that are used to assist non-geologists with evaluating complex geological information. These mineral derivative maps were created from digital geologic map data (including our 1:24,000-scale STATEMAP quads) and historical mine locations to provide information on the general distribution of select potential mineral resources.
The CGS resumed publishing extensive reports on the state of both mineral and energy resources across the state. The most recent report, based on 2014 data, was released in 2015.
The CGS has long been involved with alternative energy development, especially geothermal in a variety of forms. For more information contact: Paul Morgan
