About

Dinosaur National Monument is located on the southeast edge of the Uinta Mountains on Colorado Plateau the border between Colorado and Utah at the confluence of the Green and Yampa Rivers. The park contains over 800 paleontological sites and is home to some of the most abundant and well-preserved dinosaur fossils in the world, providing a treasure trove for visitors and scientists alike since the fossil beds were found in 1909. The region was declared a national monument on October 4, 1915. Owing to the Monument’s remote location, high elevation, and low humidity, enjoying Dinosaur National Monument’s starry night skies today is like stepping back in time.
