2023 Colorado Geology Calendar

2022-12-16 | Dr. John Hopkins

We’ve been wanting to put together a calendar for some time now, and 2023 seems to be the right year! The geology of Colorado and its landscapes are as varied and as colorful as any place on the planet. And, yes, we think this collection of images from our staff—with jobs that often include field research—does a great job showing off our favorite state! We plan to make this an annual project.

You can order your calendar on our (new) Amazon publications store.

The contest is over: after a huge response, we’ll be contacting folks in the next couple days to let them know their status!
