| 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. |
