Boulder residents and environmental stewards can breathe a little easier thanks to the recent completion of the Marshall Mesa Coal Fire Mitigation Project. This major success story follows a collaborative effort between U.S. Rep. Joe Neguse, the Colorado Department of Natural Resources (DNR), the City of Boulder, and Mountain View Fire Rescue to finally put an end to a coal seam fire that has been quietly burning beneath the earth for over a century. The remediation, which began in October 2024, ended with officials signaling the beginning of new community enhancements, including an overhauled trailhead.
During the project led by the Colorado Division of Reclamation, Mining, and Safety (DRMS), smoldering coal remnants from the region's historic mines were carefully excavated from about thirty feet below the surface. "The Marshall Mesa Coal Fire Mitigation Project is a collaborative effort to strengthen community resilience and reduce wildfire risk," said Congressman Joe Neguse, as obtained by the Colorado Department of Natural Resources. The project was a triumph of coordinated governance, aiming to extinguish a longstanding ignition source and safeguard nature and public safety.
"With their partnership and working closely with our contractors we were able to excavate problematic areas in the old coal mine and the coal seam to minimize the risk of future ignition," said Jeff Graves, Director of the Inactive Mine Reclamation Program at DRMS, as per Colorado Department of Natural Resources. The mitigation process involved blending the underground coal with cooler soil and rock before refilling the excavations, a painstaking effort to prevent potential flare-ups. The site has since been recontoured and reintegrated with native vegetation, restoring its natural topography.
With the fire now doused and the ground stabilized, the City of Boulder is set to transition the area into a recreational hub. The forthcoming Marshall Mesa Trailhead is conceived to be seamlessly integrated with the city’s expanse of open space, which includes an impressive 46,000 acres, 37 trailheads, and 161 miles of trails. "Now that their hard work is complete, we look forward to creating a whole new Marshall Mesa Trailhead experience to help visitors enjoy Boulder’s remarkable open space," said Dan Burke, Director of City of Boulder Open Space and Mountain Parks, as per Colorado Department of Natural Resources.
