The best way to run this is from north to south. To get there from Church Rocks, drop down the last long slickrock section on Church Rocks (going south) stay right and veer up the wash (west). Branch off of Church Rocks and climb the relatively steep hill to the left (south). This is a short Prospector Trail
connector. After cresting the hill, turn left at the intersection and then right down the south side of the hill. About halfway down the hill, look for the singletrack that branches to the right. It climbs onto a sandstone ledge. Follow this for about a half mile and then cross a doubletrack.
Look for the Dino Cliffs sign and singletrack that climbs the hill across the road. Follow this trail for about a mile and you'll see a short connector trail that continues straight (which is now marked "closed"). Turn right and try your skill climbing the sandy hill. Look for the dinosaur tracks on the slickrock in the wash bottom before the sandy hill. There are a few short but difficult sections.
