Hundreds of millions of years ago, long before the town of Moab existed, dinosaurs roamed eastern Utah. Tracks tell their tales. Prehistoric footprints by the hundreds are preserved in the stone surrounding this former uranium boom town, a silent record of the three major chapters, or periods, of the Age of Dinosaurs. Some of these footprints are hidden away in the backcountry, known only to experts. But others nearly run through the city, exposed along the roads leading to and through the desert community. It was in one of these more accessible places, along U.S. Route 191, that a chance discovery recently led paleontologists to one of the most spectacular dinosaur stomping grounds ever found in the state.
