This 1.2 mile (2 km), one-way trail cuts through several tilted rock layers which expose a variety of rocks and three fossil areas as offshoots of the main trail. The Morrison Formation stop features an outcropping of several small fossil fragments and a few large pieces of dinosaur bones in their natural state, just as Earl Douglass found them in 1909. Trailheads are located at both the Quarry Visitor Center or the Quarry Exhibit Hall. When the shuttle is running between the Visitor Center and the Quarry Exhibit Hall, many visitors opt to hike the trail one direction and ride the shuttle the opposite.
A pamphlet for the trail is available at the Visitor Centers. Trail maps of Dinosaur National Monument are available from the park bookstore.
