While driving out of Arches National Park one night, I came around a corner and saw this laminated sandstone illuminated by a setting sun and a rising moon. I love shooting geology. This laminated sandstone looked as though it had been poured out of a blender. In reality, the thin layers were laid down over years of deposition and subsequent evaporation. This whole area was once a shallow inland sea. Later the area, was uplifted and erosion continued, revealing these layers.
