On the Colorado-Utah border, Dinosaur National Monument is an incredible testament to the natural and geological history of the area. You can see more than 1,500 fossils on display on the cliff face inside the Quarry Exhibit Hall. There are also petroglyphs of lost cultures and the abandoned homesteads of early settlers. For the adventurers, there are camping and whitewater rafting opportunities.
