Fossilized evidence of prehistoric life is extensive in the Moab area. Dinosaur tracks and skeletal structures embedded in the rock strata can be seen on trail sides and official sites. One notable site is the Mill Canyon Dinosaur Trail which contains numerous fossils and tracks still encased in the earth. Located in a large wash, no bigger than a football field, are more than 200 tracks of about 10 different dinosaur species preserved in sets of consecutive footprints.
This self-guided walking tour of less than a quarter mile (0.4 km) leads visitors through a series of boardwalks with informative plaques detailing the dinosaurs and plants that have left their mark here. The Mill Canyon Dinosaur Tracksite was just discovered in 2009 and became open to the public in 2014. Pictures above are from multiple sites. For more information read this trail guide.
Due to the numerous fossilized dinosaur tracks in the area make sure to tell your guide your interest level to see more. Many of the remains are easy and quick to see and seem like a walk back through time.
