The trail starts on the right-hand side of the toilets and descends a short hill. The edges of the dirt trail are lined with rocks. As you near the base of the first cliff band, look up and you’ll see the dark flat boulder face with the tracks. Scramble up left along a sandstone ramp then back right across a sloping terrace below a cliff band. At the right side of the cliff, climb a short smooth slab to the dinosaur tracks.
Dinosaur tracks, more than any other kind of dinosaur fossil, are the closest we can ever come to these long extinct creatures. If we use our imaginations, they offer a glimpse into a long vanished world from the Jurassic period some 150 million years ago. Dinosaur tracks are dynamic evidence and a momentary record of a living and breathing animal that once stalked the Moab area and offer clues to dinosaur behavior.
The largest tracks on this boulder were made by the three-toed feet of an Allosaurus, a fierce upright predator with dozens of sharp teeth and small arms. The dinosaur walked across a muddy sandbar, leaving imprints of its giant feet, in a lost world with an inland sea, wide rivers, and a dense tropical forest. Water then buried the tracks with sediment, which hardened into sandstone over millions of years before they were exposed by erosion. Other smaller dinosaur tracks are also found on the boulder face as well as on other stone slabs on the hillside.
