Dinosaur National Monument
In his book, The Immense Journey, Loren Eisley wrote, "Once in a lifetime, perhaps, one escapes the actual confines of the flesh. Once in a lifetime, if one is lucky, one so merges with sunlight and air and running water that whole eons, the eons that mountains and deserts know, might pass in a single afternoon without discomfort."
Plane - Flying in to Grand Junction, CO or Salt Lake City, UT would probably be the least expensive way to fly to Dinosaur. It is roughly a 3 hour drive from Salt Lake to the park in a rental vehicle, just over 2 hours from Grand Junction. Vernal, UT does have an airport and a few flights shuttle between it at Salt Lake every day.
