Erosion caused numerous rockfalls that revealed new pages in the Clarno Nut Beds storyline on the surfaces of the boulders all around you. Paleontologists at the Monument use the effects of erosion to find new fossils on the surface instead of digging for them. Discovering these fossils allowed paleontologists to piece together the events that formed the Palisades.
