Long Description:
In the spring of 1877, a local teacher named Arthur Lakes found large dinosaur bones in the area. His discovery sparked a dinosaur "gold rush" to the Western United States, which revolutionized our knowledge of these animals. Eventually, ten quarries were opened in the now famous Morrison Formation between here and the Town of Morrison. Lakes found the bones of an Allosaurus, two brontosaurs (including an Apatosaurus and Diplodocus), and the first specimen of Stegosaurus, the Colorado State Fossil. The bones were sent to Professor O.C. Marsh a Yale University to describe, but only after Marsh's arch-rival, E.D. Cope of Philadelphia, tried to buy them. Although the bone is difficult to remove from the hard sandstone, some specimens have been successfully extracted and can me seen at the Morrison Natural History Museum. (All text for this waymark was copied from one of the signs posted at the site.)
