The formation seen above is part of the southern Nopah Range in southern California near Tecopa, California. They belong to the Bonanza King and underlying Carrara Formations, both of which were deposited in shallow marine environments during the Cambrian Period, some 500 million years ago. The strata look as if they are horizontal, but they are actually dipping eastward, away from the camera. Photo taken December 18, 2010.
