Description
Two rock slabs with footprints of meat-eating dinosaurs are visible from the pull-out on SR 279 or the parking lot of the Poison Spider trailhead. One slab is at the base of the cliffs, a second slab is halfway down the slope, just above the cliff that drops down to the road. The lower slab contains the tracks of at least 10 different meat-eating dinosaurs, ranging in size from 17 inches to 5 feet at the hips. All of the animals appear to have been walking at speeds of 3 miles per hour.
