﻿Fig. 131. — Excaw'iting' one of Puelilo Bonito's numerous i-;i\as. Mule- 

 drawn dump cars were used in connection with a portable steel track which 

 could be shifted as the explorations progressed. Owing to the depth of 

 some rooms it was necessary to pass the deliris upward from one man to 

 another before it reached the Irack level. (Photograph ]>\ Wil M. Judd.

Fig. 132. — Many instances of superjjosition have been disclosed by the 

 excavations at Pueblo P)onit(). This particular view shows the disintegrat- 

 ing masonry of a typical Chaco Canyon kiva resting directly upon the 

 partially razed walls of a ceremonial room fundamentally different in con- 

 .struction and representing an entirely distinct culture. ( Photograiih by
