National Monument Museum
On August 17, 1909, 20 miles east of Vernal, Utah, paleontologist Earl Douglass (who worked for the Carnegie Museum of Pittsburgh, Pennsylvania) discovered a 200 foot long sandbar of sorts which was layered with prehistoric plant and animal fossils. About 350 tons of fossils, including full skeletons and remains of some dinosaur species that were previously unknown, were excavated by Douglass and his crew. A quarry was built on the site and it was designated a national monument in 1915 by President Woodrow Wilson.
A year round visitor center has been built in Vernal, Utah. Here you can see over 2,000 dinosaur bones that are exposed in the sand wall of the quarry. Visitors can watch paleontologists chip away the sandstone to expose the fossilized dinosaur bones. They can also see the dinosaur fossils being cleaned and preserved in the laboratory.
So, why are there so many dinosaurs found in this area'
