What We Do One of our primary efforts is to help people live safely with the multitude of geological hazards that Colorado’s spectacular geology creates when people move into nature. We are required by statute to review geologic reports done for new developments in unincorporated parts of counties, and for all new school construction or critical facilities. Additionally, thirteen municipalities voluntarily use our talents because they believe we offer critical input to protecting their citizens. Over 350,000 copies have been sold of our multiple-award-winning publication, SP-43 A Guide to Swelling Soils for Colorado Homebuyers and Homeowners. Another of our statutory tasks is to promote the responsible development of Colorado’s vast mineral and energy resources. We produce reports and maps that compile information into useable formats for policy makers and the industry to use in making decisions. Our annual publication, Colorado Mineral and Energy Industry Activity, is filled with a variety of information on the Colorado industries that produce more than $12 billion in revenue for our economy. We also are increasingly involved in helping to solve our state’s serious water situation. Our comprehensive online ON-010 Colorado Groundwater Atlas is an important addition to our previous award-winning groundwater publications. And finally, we help people understand the importance of Colorado’s geology, particularly as it influences mineral and mineral fuel production, geologic hazards, and water. We do this through our popular RockTalk blog based on a prior paper publication, and through publications such as our multiple-award-winning Messages in Stone: Colorado’s Colorful Geology. We would love to hear from you on how you think we are doing, and any ideas you might have on how we can improve. Please use the contact form below. Current Publications CGS staff members make regular contributions to the scientific literature and are active with numerous state, regional, and national professional organizations including the GSA, AGU, ASCE, AEG, SEG, and more. Please see staff member pages in the staff directory for comprehensive list of their individual publications. Following are our most recent publications: 2020-2021 Barkmann, Peter E., Lauren D.
