For me, the draw of this monument is not the dinosaur fossils, but the amazing landscape that the park encompasses. This was our first scenic stop on our route from Memphis back to Oregon. Rob’s ankle had been giving him trouble (he had been wearing a boot and on crutches the week prior), so we chose a route that would allow us to do some auto touring at a leisurely pace to break up the days on the road. Dinosaur fit the bill. Jaw dropping landscapes in the middle of nowhere, just my sort of place! We were here on a Saturday, and only crossed paths with a handful of people/vehicles in the Colorado portion of the park. The quarry is the highlight for most visitors and was busier, yet still not crowded. The park lies on the southeast flank of the Uinta Mountains on the border of Utah and Colorado. The park was formed in 1915 following the discovery of dinosaur fossil beds in 1909. The beds were exposed by forces of erosion in rock of the Morrison Formation from the Jurassic Period, formed approximately 150 million years ago.
