Dinosaur National Monument is located on the southeast flank of the Uinta Mountains on the border between Colorado and Utah at the confluence of the Green and Yampa Rivers.
Dinosaurs once roamed here. Their fantastic remains are still visibly embedded in the rocks. Today, the mountains, desert, and untamed rivers flowing in deep canyons support an array of life. Petroglyphs hint at earlier cultures. Later, homesteaders and outlaws found refuge here. Whether your passion is science, adventure, history or scenery, Dinosaur offers much to explore.
Dinosaur National Monument is located on the Colorado and Utah border with a parts of the monument in both states. Dinosaur fossils are not visible in the Colorado portion of the monument - only on the Utah side. The Quarry Visitor Center and Exhibit Hall (where you see the dinosaur fossils) are located approximately 7 miles north of Jensen, Utah.
Canyon Visitor Center - Colorado
Located near Dinosaur, Colorado, at the base of the Harpers Corner Road, the Canyon Visitor Center is the gateway to the monument's mountains and river canyons. This building is open daily in summer and is closed during the winter. Exhibits and a park film orient visitors to resources, and staff are available to answer questions. A bookstore sells items that can further enhance your experience. Restrooms and water are available seasonally. There are no dinosaur fossil sites on this side of the park.
Located on US Hwy 40, two miles east of Dinosaur, CO.
Quarry Exhibit Hall - Utah
The Quarry Exhibit Hall is where you can see a wall of approximately 1,500 dinosaur bones. This includes the remains of numerous species, such as Allosaurus, Apatosaurus, Camarasaurus, Diplodocus, and Stegosaurus. Exhibits, including an 80 foot (24 m) long mural, reveal the story of the many animals that lived in the Morrison environment during the Late Jurassic. This building is open year-round, except on certain holidays. Open hours change seasonally.
Quarry Visitor Center - Utah
Located 7 miles (11 km) north of Jensen, Utah, off Highway 149, the Quarry Visitor Center is the gateway to the Quarry Exhibit Hall and the wall of dinosaur bones. This facility features a staffed information desk, gift shop, and theater with a 12-minute park film. Exhibits introduce a variety of resources and places to explore within the monument.

Landbird Monitoring in Northern Colorado Plateau Network Parks, 2018
Because birds can be sensitive to habitat change, they are good indicators of ecosystem integrity. The Northern Colorado Plateau Network partners with the University of Delaware to assess breeding-bird species trends in three different habitats: low-elevation riparian, pinyon-juniper, and sage shrubland. Find out which species were increasing and declining at network parks as of 2018.

Predicting Vegetation and Topographic Change in Response to Altered River Flows on the Northern Colorado Plateau
Lots of things can impact the quality of your raft trip. Weather. Water levels. Packing the right (or wrong) gear. But would you expect plants to play a role? Riparian plants influence the shape and character of rivers—and river flow helps determine what grows where. This model can help river managers predict the downstream effects of shifts in flow, and respond accordingly. The model was tested in Dinosaur National Monument.

Series: Geologic Time Periods in the Mesozoic Era
The Mesozoic Era (251.9 to 66 million years ago) was the "Age of Reptiles." During the Mesozoic, Pangaea began separating into the modern continents, and the modern Rocky Mountains rose. Dinosaurs, crocodiles, and pterosaurs ruled the land and air. As climate changed and rapid plate tectonics resulted in shallow ocean basins, sea levels rose world-wide and seas expanded across the center of North America.

Series: Geologic Time Periods in the Paleozoic Era
During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era.

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Only a small number of women held temporary ranger positions in national parks during World War II. Carlsbad Caverns National Park, national monuments in the Southwest, and historical sites in the East continued to employ more women. Although a few women veterans benefitted from post-war veteran hiring programs, most veterans were men and permanent positions became even more difficult for women to get.
