The three stacked loops of Alien Run offer a variety of riding for everyone. Trails flow through smooth dirt arroyos, traverse along slickrock cliffs, and session through natural technical features. The further one rides from the trailhead, the more difficult the trail; the one-way Outer Limits trail is characterized by sections of rocky climbing, plunging downhill sections, and meandering through dune-like terrain.
In March of 1948, a UFO was rumored to have been tracked by radar and discovered on a lonely mesa top by U.S. military and scientists. A large metallic object with over a dozen humanoid aliens and strange hieroglyphics inside the craft were found. Trucks disguised as oil field work trucks hauled off the craft and its decease occupants, leaving the area now known as Alien Run.
