Brown played a key role in bringing national attention to the Dinosaur National Monument quarry.
Barnum Brown was an influential and iconic paleontologist employed by the American Museum of Natural History in New York City. Brown had a keen interest in the development of the quarry at Dinosaur National Monument. Brown visited the quarry in 1936 and made suggestions in a corresponding report regarding the development of an in situ exhibit at the quarry. By this time, Brown had developed a relationship with the Sinclair Oil Company, and even made the suggestion that Sinclair could provide funding for the development of a quarry exhibit and museum. However, these plans never came to fruition, a quarry museum would not be developed until twenty years later by the efforts of the National Park Service. Despite Brown not being able to follow through with the development plans the American Museum of Natural History and the National Park Service had for the quarry, Brown played a key role in bringing national attention to the Dinosaur National Monument quarry.
