[1][2] Keyhole Sink, formerly called Box Canyon, is a few miles east of Williams off Route 66 in Kaibab National Forest, and can be accessed on foot by a short, unpaved pathway known as Keyhole Sink Trail.

Archaeological research suggests that not many people actually lived in Keyhole Sink, and that it was mainly used as a sort of sacred rest stop for hunters and as a place for clan initiations.

Surrounding the site for a radius of fifteen miles are remnants of pit house foundations.

Design elements include snakes, lizards, deer, and amorphous images.

The petroglyphs are considered to be heavily weathered, and in August 2010 vandals caused extensive damage by painting huge letters on them with "silvery white paint."
