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.)
Park at the parking coordinates listed below. There are two main
