SEDONA, Ariz. (AP) — The U.S. Forest Service said a half-mile of trail that was illegally built near the heart of Sedona caused severe erosion and damage to an archaeological site in the scenic tourist area.

The trail was built just south of the main village near the mesa holding the town’s airport and is just the latest example of illegal trail-building in the Coconono National Forest by either hikers or mountain bikers trying to create their own routes through the scenic area.
