Keyhole Sink Trail #114

Area Status: Open

This trail provides the visitor with an easy-to-hike pathway to a scenic box canyon where prehistoric residents left their mark 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 as 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. Take note of that and keep a sharp eye. This area is still an excellent place to encounter wildlife. While you're visiting the Keyhole Sink Trail, please respect the irreplaceable traces of the past that you find along it. Leave them undisturbed so that others may enjoy them as you have.

The trail traverses easy terrain through a ponderosa pine forest. The return trip from Keyhole Sink is over the same trail. The trail is marked for cross-country skiing with blue triangles.
