Layered sandstone.

The capping stone of the ridge is dominated by the distinctively layered sandstones that formed during the Pennsylvanian Period of the Paleozoic Era some 300 million years ago. This sandstone, called “Pottsville Sandstone,” is hard and resistance to erosion which explains why it has persisted on the upper sections of this ridge. This stone ...

The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. The photo shows layers of rock on top of one another in order, from the oldest at the bottom to the youngest at the top, based on the principle of superposition. The predominant white layer just below the canyon rim is the Coconino Sandstone.
