Dinosaur Hill may no longer be an active dinosaur dig site but it has yielded important finds. In 1901, Elmer S. Riggs, Assistant Curator of Paleontology at the Field Museum in Chicago, unearthed roughly 2/3 of an Apatosaurus, the 70-foot plant-eating dinosaur once referred to as the Brontosaurus, at this spot between Fruita and Colorado National Monument. The 1-mile, self-guided interpretive trail offers insight to the area’s paleontological and geological importance and includes a stop at the site excavated by Riggs.
The boulder above bears the mold of a femur (upper back leg bone) of a Diplodocus-like dinosaur. Fossils of various freshwater clams are also embedded in the boulder, which was submerged in the ancient river channel. The boulder broke away from it's original position, several feet higher up the hill.
Dinosaur Hill is located 1.5 miles south of Fruita on Hwy 340. From I-70, exit 19 - CO 340 (Fruita/US-6/Colorado National Monument). Turn left on CO 340 and travel south.
