BLM New Mexico COVID-19 Information Update

The Department of the Interior’s current COVID-19 policy incorporates CDC guidance. As CDC science-based guidance changes, our policy will adapt. Visitors have always been encouraged by DOI to review CDC guidance when making their plans to recreate responsibly. CDC guidance indicates that fully vaccinated people no longer need to wear a mask or physically distance in any setting, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations. Unvaccinated people must wear a mask indoors in DOI buildings at all times and outdoors when physical distancing cannot be maintained. All people, regardless of vaccination status, are required to wear a mask on all forms of public transportation and in healthcare settings on DOI lands. We will continue to ask visitors to follow CDC guidance to recreate responsibly.

The latest information on changes to facilities and services in response to Coronavirus (COVID-19) is available here.

New Mexico Mountain Biking Opportunities: Alien Run

The Alien Run Trail System provides mountain bikers with the opportunity to experience a variety of trails in a high desert landscape. The trails are named for a rumored UFO crash site in the area.

The trails here provide a wide variety of experiences including; playful and flowing single track, exposed sections along the tops of escarpments, slickrock play areas, and loose and rocky challenging trail with significant changes in elevation.

The Alien Run Trail System is found in the southwestern reaches of the Colorado Plateau, a large physiographic region dominated by sandstone formations and pinyon-juniper forests.

One of the Bureau of Land Management's "Backyard to Backcountry" treasures, information on the Alien Run Trails-Super Loop was developed between IMBA and the Farmington, NM, BLM office to provide world-class riding experiences. IMBA's data on the trail includes elevations, ratings, current conditions, photos, and comments.
