In Parks, AZ on the Kaibab National Forest, the Keyhole Sink Trail provides the visitor with an easy to hike pathway to a scenic box canyon where prehistoric residents left their marks carved into the canyon's gray volcanic walls. Roughly 1,000+ years ago, some ancient artisan or artisans pecked images into the dark basalt using another rock for a tool. These images are called petroglyphs. The message that they portray suggests that the area was important to that ancient communicator as a hunting ground. One of the petroglyphs is a dramatic depiction of a deer herd entering the canyon. The trail traverses easy terrain through a lovely ponderosa pine forest. During the winter, the trail is popular with cross-country skiers, as the route is marked with blue triangles in the tops of trees in order to easily define the path even when there is snow on the ground. Visitors at the Keyhole Sink Trail are asked to please respect the irreplaceable traces of the past by leaving them undisturbed so that others may enjoy them. Here you see Williams Ranger District Archaeologist, Neil Weintraub, observing petroglyphs at the site. Williams district. 12-3-18. 20181203-FS-KAIBAB_LSC-0731. Photo by Lance Cheung.
