You know it, you love it… and it’s about to get even better!
The Colorado Department of Transportation just announced that the I-70 Dakota Hogback Point of Geologic Interest trails are about to be rehabilitated. The trails will be improved upon to increase access and safety, ensuring they will remain stable in the coming decades. Over 2,000 feet of trail will be revamped, including both the North and South Trails. The old signage in the area will also be replaced with updated interpretative plaques. Construction will be undertaken June through October 2026. CGS is proud to support this project and ensure that the iconic I-70 roadcut remains a world-class stop for generations to come. See the full statement from CGS below:
“The Point of Geological Interest along Interstate 70 west of Denver is a world-class outdoor classroom viewed by millions of residents and visitors every year. Restoring public access to this site and replacing decades-old, weathered signage with new interpretive displays helps bring Colorado’s remarkable geologic and paleontologic story back to life for a new generation.
This effort was a true collaboration involving CDOT, Jefferson County, Dinosaur Ridge, Goodbee & Associates, and technical contributors from organizations including the Colorado Geological Survey, USGS, Denver Museum of Nature & Science, Colorado Scientific Society, and many dedicated volunteers. The roadcut itself is one of Colorado’s most recognizable geologic features and provides an accessible window into the dynamic processes that shaped the Front Range and Rocky Mountains.
The Colorado Geological Survey is proud to have supported this project and to help ensure these important geologic resources remain publicly accessible, educational, and inspiring for generations to come.”
Please contact CDOT with any questions regarding construction. This project is not expected to impact traffic, but please be aware of workers on the side of the highway.
