Description:A photograph of cliffs. The caption at the back of the photograph reads "Within the cliffs thick sandstones are seen interbedded with shales. The shales were deposited in front of the giant delta and contain marine fossils. The sandstones filled the river channels which meandered through the marshy delta top. Occasionally the sandstones contain fossil plants.".
