Great trail. If you want to get to the top of the cliff where the dinosaur tracks are below, take the overlook trail that branches of the Joe Johnston route. The overlook trail has a beautiful view of the canyons and has some safe areas to sit near the edge of the cliff. Also, if it rained recently, the dinosaur tracks may be underwater and the Joe Johnston route may be impassible unless you want to wade through water. If that's the case, take the overlook trail and you can see the tracks from the cliff's edge and the overlook trail will take you back to the Joe Johnston route on the other side of the flooded area.
