Customers were asked to briefly describe a project where the information or service they received from the Colorado Geological Survey:
  • Enhanced the project.
  • Madethe project or some aspect of the project possible.
  • Ifnot usedfrom a project standpoint, if the information was integral to their line of work on an ongoing basis.

Here are their comments in the order received by the Survey:

I am a retired geologist but I volunteer with Boulder County and City helping interpret the geology of their properties. Geologic maps are absolutely essential.
Put together an oil exploration project in the DJ basin, and used the groundwater atlas to help with the shallow geology.
We are frequent campers in Colorado with a high interest in the geology of the State. CGS maps and information help make our camping and hiking much more interesting than they would be without them.
CGS information is useful for course lectures.
CGS information was useful in building a 2 week field trip for my students.
CGS information has been useful in past research projects in the Pikes Peak region.
CGS information has been useful for me as I can advise my family who still reside in Colorado, regarding hazards and natural resources.
Helps club in planning great field trip and supplies info & maps to succeed.
I am a retired professor of computer science, and like to remain aware of what is happening in areas of natural science.
Work is confidential and proprietary.
I write a blog about Colorado water issues. I use your graphics and reports on the blog, sometimes as an adjunct to news reports, sometimes as the focus of my blog post.
We are concerned with the political nature of the COGCC and need to prepare County regulations based on fact and not innuendo. Your data enables some of this analysis.
CGS provides an invaluable service to the citizens of CO – keeping our housing stock hazard free and helping our governments make fact-based decisions, including energy, residential and commercial development.
CGS is integral to our work in both engineering and economic geological exploration in many ways. Please do not make the fatuous mistake that the State of Georgia did with their geological survey.
Taught a unit on natural resources and mining.
Geothermal locations.
General knowledge only as I am retired.
Geology of Chaffee County, CO.
Trajectory simulation of rockfall to position protect steel barrier on a road in Italy.
I am a research geologist and conduct occasional educational course work. I use CGS materials to support my efforts and find them invaluable to the work that I do across the entire state.
As we continue to assess the oil and gas potential of the Niobrara Member of the Mancos Shale in the Piceance Basin, we will be working with individuals at the CGS to better constrain the boundaries of the petroleum system by using the geologic maps of the area. We also consult with the interpreting geologist to find additional outcrops for future study to enhance our understanding of the petroleum system.
We use base data from the CGS for natural resource protection and Geological Hazard delineation in Oil and Gas exploration.
Our project involved researching the water resources of the Cheyenne Basin for industrial water supply development potential. Cooperative arrangement in which CGS prepared a specific report on ground-water vulnerability on a watershed scale. Greatly helps in federal land management.
I used it connection with construction of my house in an geologically unstable area and successful oopposition to zoning of an adjoining property.
Base map – previous work.
My company used geological information from CGS. The info enhanced our operation in Colorado, but we could have made do without itat our own cost.
My prior work as a consultant included writing hazard mitigation plans. The CGS was a keystone data resource for producing excellent plans. Staff was always helpful and willing to get me the most accurate and effective data/map to use for my research.
I am a rockhound.
Keep up the great work!
Retired PG in FL, obtaining info for personal reasons.
Looking for coal/energy investment opportunities for client company.
I purchased a publication for my Gold Prospecting club. The publication has become a so-called ‘Bible’ for our members.
Our project required the detailed information on expansive soils and particularly the steeply dipping condition where a home was distressed and need significant remediation.
I am just a home owner with an interest in geology. Any project I have geologically is personal interest of Colorado geology, and for some background in creative writing.
I use the geological map cards to teach geology of Colorado to my class. They are a valuable visible resource to see where ancient volcanoes are located as well as mining resources.
I don’t work (retired). Info received is interesting.
I have my high school Geology students research Colorado’s geologic natural hazards and present their findings to the class. This information is readily obtained from CGS publications, but would be difficult to obtain efficiently elsewhere.
I last used CGS information in a PowerPoint presentation I had to create for a Historical Geology class. I also use CGS information for rockhounding, fossil hunting and as a general knowledge base.
I am an oil and gas geologist in Louisiana. I love the Facebook posts and regularly share them.
I am interested just as an individual. The information is for personal reasons and not work related.
Semi-professional photographer interested in geological sites in Colo.
Geothermal assessment. Published geothermal studies and geologic mapping were used during the investigation.
The collapsible soils publication by John White proved critical to a forensic evaluation of several settling structures near Avon, CO. We also regularly use the quaternary fault and fold database.
While doing preliminary geology and geotechnical work for a proposed development near Winter Park, Colorado, I found an unpublished (student?) map of the area in the ‘back room’ of CGS which helped confirm our interpretation of a large landslide in the area of the development.
EIS of the Rueter-Hess Reservoir
I’m a professional geologist who practices in the western US, but not in Colo (owing to the lack of work from lack of professional licensing). I use CGS research and products as a framework for doing geology in other geologically similar areas.
Water well feasibility report for ranch located across state line.
Large projects such as dams and tunnels always make use of State geologic data if available. None of my projects are in CO so have not used.
Geological hazard information is obtained regularly through maps and consultation. A non-biased review of geohazard mitigation concepts is invaluable to our organization. The CGS provides this service regularly.
I use geologic mapping at the quadrangle scale and geohazard publications to serve as a starting point for more focused geotechnical studies of specific projects. I have almost 40 years of experience and find CGS work to be of very high quality since its beginning under John Rold. Often, I find CGS work to be more accurate than USGS. You should be proud of the service you provide to the people of the State of Colorado. It sounds like political sniping will ultimately do you in as we know you. Being thrown to academia is a horrible, terrible idea. CSM and other colleges should stick to training tomorrow’s talent, not finding innovative ways to suck state monies to pad their nests. You should remain independent of anyone other than DNR. Although I have had minor technical disagreements with staff over the years, I believe almost every related project has been better because of the discourse. I find agreement more than disagreement and respect your work immensely. The State of Colorado should be looking at ways to make sure the high quality of service remains after all of my peers in CGS retire over the next few years. There are geo-professionals and developers that need need to be kept from doing stupid things. This is just the stuff I work with every day. The other services you do related to minerals is irreplaceable. Talk about ways to build investment in Colorado from outside! Vince, Karen, David, et al – keep plugging!
Geologic maps and hazard maps and conversations with CGS on their past experiences with geographic areas of interest.
Geologic maps were useful in siting a second home in Park County and learning more about expected soil properties for septic system.
We utilize CGS data on a daily basis for enviro & geologic projects throughout the state of CO. We use historic publications, we use GIS data, we use your free pubs, we use it all. We would be out of business if it were not for the accurate, unbiased data & information produced by CGS. There is no substitute for an agency like CGS and it is absurd to think that private-sector contractors could ever replace all the great things that CGS is responsible for. If anything, the scope of CGS’s mission (and their budget) should be greatly expanded.
Helping clients evaluate undeveloped coal resources to build a new mine.
Chris Carroll provides a wealth of knowledge of depth for the entire Colorado coal industry. Mr. Carroll provided concise data we could use immediately, without much post processing.
Used for evaluating mines and mineral resource areas.
Providing geologic information and sources to teachers, students, local governmental agencies empowers these contacts to make educated and enlightened decisions.
Exploration for rare minerals/gemstones requires information not typically available from USGS or commercial sources.
We are a small exploration company and we use the CGS services to help qualify or reject selected areas deserving of further investigation.
We use basic geologic data, mineral potential, historic mining information, environmental restriction data (Wilderness, protected areas, etc.).
“For every new reservoir investigation we do, an earthquake hazard evaluation is required by the SEO. We use earthquake location and magnitude data from the CGS and USGS in GIS format, which streamlines the work related to this task. It is important that the earthquake data we obtain is frequently updated when new earthquakes occur.The published geologic maps we use from the CGS provide an important base of information from which to build our geologic models. The quadrangle scale geologic mapping enhances our services because we are able to efficiently identify regional geology/geologic problems that may or may not (but often do) impact our projects. For example, the mapping helps us to understand the potential foundation or borrow issues associated with a site before we begin or propose on a project.”
Historical coal mine production records for the various counties in Colorado.
We use the information in education and training efforts for the mining community. However, as a former exploration geologist in the minerals industry, geologic maps and geologic reports regarding mineral potential were extremely useful and important in our efforts to efficiently utilize our exploration funds for locating and defining mineral resources. This information is a foundation for mineral investment in Colorado, location of economic resources and increasing employment for those involved int he extraction and reclamation of the mineral resource.
Idenifying coal resources, seam thicknesses, depth, and previous mining activities within the projected area.
Sorry; this survey does not apply to our human resource consulting firm located in South Carolina.
Mt. Princeton geothermal development. Colorado geothermal potential and other areas warranting exploration. Use maps for recreation.
All of our mapping in Colorado is done in consultation with the CGS.
“1. Induced seismicity related to resource extraction. 2. Collaborative geologic mapping:Central CO. 3. Uranium mining environmental hazards”
Acquired information to support valuation work on uranium property.
The Hydrogeological Services Group at DWR uses CGS publications, studies, and data regularly in our work on a day-to-day basis. Our work that uses CGS products includes regulatory aquifer determinations to determine allowed pumping strata, quantification of water resource, and pumping rates. It also includes regulatory groundwater determinations on which applicants and opposers spend large sums of money to prove the tributary or non-tributary status of certain water-bearing zones. CGS studies provide objective scientific information that helps us discern the true nature of the groundwater and to regulate appropriately.
A project called for a recommendation on whether and how to proceed with exploration on a Colorado mining property. CGS reports provided critical and unbiased information on property.
I evaluated a potential resource in Colorado and needed maps and other information for my analysis.
Landslide evaluation and recommendations for mining and remediation.
“I used references: Resource Series 28 – CGS/SP 52”
I work in the minerals industry and have to deal with a wide variety of resource and environmental issues. The CGS provides a central clearinghouse of valuable information that cannot be easily obtained elsewhere.
Our project involves mapping the upper Arkansas River valley region. CGS maps have been invaluable in reaching our project goals; 14 CGS geological maps cover approximately half of our project area.
Historic and current data applicable to mineral, including uranium, exploration is most useful. Information on groundwater is helpful in permitting mining projects.
The purpose of Denver Chapter of WOMEN IN MINING is to educate – our members about technical issues (such as coal-related subsidence and the potential for rare earth exploration in CO) and to educate the public (schools, museum, adult organizations) about mining and the mineral resources we have in this state (CO), as well as throughout the US.We are also trying to get school-aged students interested in EARTH SCIENCES – and we have such a great opportunity to show & persuade students its ok to like science. It doesn’t hurt to spark an interest in these young people to consider going into geology, geotechnical engineering or mining engineering – but they have to KNOW about it first. CGS provides materials and assistance in our quest to EDUCATE the public about what our state has for resources.
We use the info for market research, mineral estimation, etc.
MSIC referrals
Our mineral exploration activities are outside of Colorado. Otherwise, we would probably utilize your services.
Interested in Mineral resource information and geologic hazards.
For a recent infrastructure project, the 7.5 min quad geologic map was a publication by the CGS. We also used a coal mine subsidence report that was available through the CGS. These two sources of information were critical to estimating the subsidence risk, and developing a plan for further investigation.
Most of the time other people obtain the information from the Colorado Geological Service. I don’t go directly to them. I know the information is valuable to our project work.
I have used the CGS maps and reports as general references, enhancing my knowledge base and informing myself of other occurrences of mineral resources, and how they might be used and located.
Looking for azurite and malachite tailings.
CGS information is vital to the National Mining Hall of Fame and Museum. We get many questions about Colorado geology and like to stay informed so we can inform others.
The Colorado Groundwater Atlas is good, up-to-date information.

“Our company is currently starting to see more and more hydrogeologic studies for tracking possible groundwater contamination from hydraulic fracturing operations as well as high demand from oil & gas operators needing to obtain water for fracking purposes from groundwater and surface water resources. I have used several publications from the Colorado Geological Survey for this work.Despite the poor state of the economy, there is still a huge need for the preservation of the Colorado Geological Survey. We live in a time of self-evident dramatic climatic change that has placed extreme measures on our groundwater resources and surface water resources. We also live in a time in American history in our nation is making tremendous strides towards energy independence. Colorado plays a vital role for energy independence with our vast gas, shale oil, oil shale, coal, and uranium resources. Coupled together, these forces are colliding and are a life necessity. It is unthinkable to eliminate oil & gas and groundwater resource information at this time! Energy, water, mining, and environmental companies need as much geologic information as they can possibly get their hands on.

Also, the Colorado Geological Survey has provided me with a plethora of readily available information on geologic maps, geologic hazards, and GIS data that I have used extensively in both my professional occupation in Hydrogeology as well as for research purposes in my academic career here in the state of Colorado.”

GIS analysis of gas pipelines and site investigation for road and subdivision development.
I don’t know where we would turn for information used in nearly all our projects if the CGS were not there.
I recently wrote a book about Front Range geology for a popular audience. I relied extensively on CGS publications (maps, technical books, and RockTalk issues) to educate myself about aspects of Colorado’s geology with which I was less familiar. I incorporate the knowledge of Colorado geology I gained from this project into my presentations in every college class I teach. I could still do my job if the CGS materials didn’t exist, but I would be less informed about Colorado geology. The students are most engaged when the material they learn is relevant to their own lives. When we use Colorado examples to illustrate fundamental geologic processes they become excited. The student experience would suffer (as would my own research about Colorado’s geologic history) if the kinds of publications that CGS does so well were to stop being made.
General information on mineral industry in Colorado, geologic reference reports, geologic maps, ground water maps and information, ability to call and discuss specific questions with a CGS representative.
Information on the Tallahassee Creek uranium district.
I used geologic mapping by CGS to evaluate dam site alternatives.
Working detailed knowledge of energy-related information and data from the CGS personnel is difficult and even impossible to replace. In some cases we have directly funded work that we can not perform ourselves.
“As a geological/geophysical consultant in oil and natural gas exploration, the surface mapping that the survey does is very valuable. Mapping is time consuming, costly, and requires quite a bit of pre-planning, which makes it very difficult to do on an individual basis. High quality mapping as done by the survey both facilitates my work and decreases risk in drilling, which improves the cost effective development of the state’s resources and reduces the environmental effects of that development.As a homeowner and 35 year resident of Colorado, I am very concerned about the geological hazards in the area. Publications and field trips done by CGS members have greatly increased my knowledge in this area. The quantification and knowledge base of water resources related to their appropriate development based on scientific decisions is critical to the future of the state, its residents, and its economy. The CGS is and will be the principal source of providing this information to the public, lawmakers, and regulators!”
Maps used on a regular basis.
I use CGS data on a continuing basis to monitor mineral resources activity in Colorado.
The information was energy-resource related to renewables and wind resources in Colorado.
All About Mining class for K-12 teachers from Colorado, other states, and foreign countries. CGS help has been given to this class for the past 44 years. Check out for details.
The project was the evaluation of the risks and potential to re-open precious metal mining in the caldera areas of Southwest Colorado. Project decisions were entirely based on maps and personal conversations with CGS staff and there were no options for the important information provided. I use CGS geologic maps and reports as data sources in the preparation of geotechnical reports for my clients.
Coal Property Economic Assessments
We perform oversight and permitting services for sodium mineral production in the Piceance Basin. Work with the CGS is an integral part of our operation. We would be at a great loss if the CGS is not available to us.
Consulting geologists need access to all kinds of geologic maps on a continuing and changing basis depending on current project(s)
