This view shows complexly folded and faulted Precambrian-age
schist and gneiss (Orocopia Schist) mixed with layers of middle to late Miocene-age
volcanic tuff and sediments of the Dos Palmas Rhyolite (Dibblee, 1954). These are juxtaposed
to steeply dipping beds of lower Mecca Formation (Pliocene) -- these
beds are visible along the sides of the canyon just beyond the vehicle.
This location is in a side canyon about one-half mile downstream from the
parking area at the end of Painted Canyon Road. |
