low the rim. However, the inaccessibility of these ore beds makes it 

 impracticable to work them. From Grand View Point, excellent views 

 of the canyon can be obtained. Directly across the river rises Vishnu 

 Temple, one of the largest of the temples in the canyon, and behind it 

 a still larger butte called Wotan's Throne. At the base of this temple, 

 the river makes an abrupt turn at right angles, assuming a northerly 

 course, which is followed for many miles, in fact, until after the Utah 

 boundary has been passed. 



Leaving Grand View, the road again leads away from the canyon 

 to avoid two or three small side canyons and the rim is next approached 

 at Lincoln Point. From this point one can look the entire length of 

 the Kaibab Division of the Grand Canyon, as it is situated directly at 

 the turn of the river. This is one of the most impressive of all the 

 views of the canyon, and is one of those often reproduced in pictures. 

 Farther along one comes to Desert View where the high plateau of 

 the Kaibab limestone drops abruptly to a lower level. A little beyond 

 the Little Colorado river empties into the main stream, marking the 

 eastern limit of the Kaibab Division of the Grand Canyon, beyond 

 which the buttes and mesas are lacking. From here there is a remark- 

 able view over the Painted Desert, and one can see in the distance, 

 many isolated rocks and mesas marking the existence of higher beds 

 of rock which have been eroded away from the main plateau. The 

 total distance from El Tovar to Desert View is about thirty-five miles. 



On another occasion we visited Havasupai Point. This is the most 

 notable of all the promontories jutting out into the canyon from the 

 south wall, and extends farther north than any other. It lies about 

 thirty-five miles to the west of El Tovar Hotel, and directly opposite 

 a very large amphitheatre on the north side of the canyon, called the 

 Shinumo Amphitheatre, after the creek which drains it. It is one of 

 the largest of the vast recesses which have been formed in the north 

 wall of the canyon, and is due not only to the erosion of the rock by 

 the creek, but also to two large faults which cross that region from 

 northwest to southeast. These two faults are in reality the branches 

 of one large line of displacement which runs for miles through north- 

 ern Arizona and southern LItah and is known to geologists as the West 

 Kaibab Fault. It is a displacement of several thousand feet and marks 

 the western edge of the Kaibab Plateau. It can be clearly seen from 

 the south side of the canyon, as the rocks to the west of the line of 

 faulting are bent downward towards the fault, as shown in figure 61. 



At the point where the fault intersects the north rim of the canyon,
