Dinosaur National Monument, located on the border between Colorado and Utah, takes visitors back to a land before time, when dinosaurs roamed North America's southwest some 150 million years ago.

This site is renowned for its layers of brilliantly colored sandstone and conglomerate rock, enclosing fossils of dinosaurs and prehistoric animals that were washed into the region and buried during an ancient flood event during the Jurassic Period.

Visitors are able to view Dinosaur’s famed Carnegie Quarry, a 150-foot long by 50-foot high wall embedded with approximately 1,500 dinosaur bones—something they had been unable to do since the old visitor center closed its doors in 2006 due to structural problems.

Many Fremont petroglyphs are dotted throughout the monument, however, due to problems with vandals, most of the sites are not listed on area maps.

The monument lies at the center of Greater Dinosaur — an area centered around the iconic Green and Yampa Rivers, which draw families from around the country for spectacular float trips. The region boasts some of America’s most treasured populations of elk, mule deer and the imperiled greater sage-grouse.

Oil and gas companies have sought to dominate greater Dinosaur’s economy. To the north, south and west, the oil and gas industry has leased off massive swaths of public lands resulting in dwindling big-game herds, skyrocketing air pollution and threats to some of America’s most iconic landscapes. 

The Wilderness Society is working with local citizens, elected officials and government agencies to ensure that energy development does not harm pristine lands and that it’s done in a way that protects the clean air, pure drinking water, outstanding wilderness, wildlife and recreation that make the region a tourist attraction. Recently we scored a victory for Greater Dinosaur’s Vermillion Basin, putting it off limits to drilling.
