"Here they range in depth from 3 to 10 feet. Upon 3,000 ft. In the lower half there are irregular thin bands of a greenish color, sometimes nodular and then con- tinuous and in thickness from 1/4 mile up several miles in depth. It seemed to me these are caliche deposits. When one gets to Ledoma we found the formations to be more beautiful amphitheater of Lupai temple pillars and jagged spurs. Near all of these are of the Lupai and it is not as one gets nearer the Rim that the Cocoonine and the Raitat are pre- sent. This place ought to make a good tourist place. Ledoma from Oak Creek about 33 miles from Jerome or 37 miles from Flagstaff. Most of my films 3, 4 and 5 (1-2) are of this Ledoma area. The Lower Lupai appears to be unbroken in the Upper Lupai (about 3,000 ft), which is tan and because it has for some finding to pull out white sandstone from 3 to 10 feet thick. Many all of these are decidedly corroded. Then the Upper Lupai appears to form broken into the thick Cocoonine (3,700 ft thick), and below it is corroded but soon goes into the dry foresetting or well seen in the Grand Canyon. Most of the sand grains are somewhat rounded and the cavern bands are of well rounded sand like the Tor Speciman itself. It was not well enough exposed to look for any phidion tracks. The foresetting
