| A view from a moving vehicle while traveling southbound along Highway 14 through Red Rock Canyon State Park, California; the strata belong to the late Miocene Dove Spring Formation of the Ricardo Group. Reddish layers are channel sandstones deposited in rivers and streams; greenish-gray beds are sandstones that were deposited along great floodplains of the Miocene, roughly 10 million years ago. The pinkish material at extreme right is a volcanic tuff. |
