Customer Service

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.

PLEASE NOTE: Because of the Coronavirus (Covid-19) situation, we can no longer accept pick-up orders at our office on the Mines campus. All orders must be shipped.

Telephone: 303-384-2655


Telephone help and email queries are addressed M-F 8:00 AM through 5:00 PM Mountain Standard Time. Orders are filled Monday through Friday, with the exception of regular state and federal holidays.

You may also use the contact form below for queries. We may take up to 48 hours to process these, although we usually respond the same day.
