Mill Canyon Dinosaur Trailhead Interpretive Site

Mill Canyon Dinosaur Bone and Track Interpretive Sites, located just north of Moab, offer visitors two unique paleontological experiences. The tracksite is accessible via a short boardwalk with interpretive signs and showcases over 200 Early Cretaceous dinosaur footprints from a variety of species, including theropods, sauropods, ornithopods, ankylosaurs, birds, and even crocodilians. About a mile farther down the road, the Bone Trail features fossilized dinosaur bones still embedded in rock along a self-guided, family-friendly path with educational panels. Both sites are set against striking desert scenery, making them ideal for learning and photography.

Discovered in 2009, the Mill Canyon tracksite preserves more than 200 footprints in the Early Cretaceous mudstone of the Cedar Mountain Formation, dating to about 112 million years ago. These trace fossils, labeled Megalosauripus and other ichnotaxa, record the movements of a diverse Mesozoic fauna. The Bone Trail exposes in-situ dinosaur bones from the Late Jurassic Morrison Formation, approximately 150 million years old, including species such as Allosaurus and Camarasaurus. Interpretive signage explains the geology, species represented, and the legal protections in place to conserve these irreplaceable resources.
