BLM seeks public comment on parking lot expansion at Sand Canyon and Rock Creek trailheads

DOLORES, Colo. – The Bureau of Land Management Tres Rios Field Office is seeking public comment on an environmental assessment that considers expanding parking areas at the Sand Canyon and Rock Creek trailheads to improve access to Canyons of the Ancients National Monument. 

These areas are directly west of Cortez and are the most popular place to begin to explore the monument. Currently, over 30,000 visitors a year utilize the area for recreation and parking has been an ongoing dilemma. 

“We appreciate the public’s input as we consider ways to improve parking and enhance public safety in this area,” said Marietta Eaton, Canyons of the Ancients National Monument, Museum and Visitor Center Manager.

The South Sand Canyon Trailhead/Parking Area improvement project analyzes the development of a larger parking area and trailhead to improve access to the existing trail network.

Recreation on BLM-managed public lands in Colorado generated $591 million and supported 4,827 jobs in Fiscal Year 2016.

The environmental assessment is available for review at Comments should be postmarked by Aug. 13, 2018, and can be submitted to the BLM Tres Rios Field Office, 29211 Hwy. 184, Dolores, CO 81323 or via email to
