EXPLANATION OF PLATE 24 



Fig. 1. North bank of Mohave River one mile southeast of Field. 

 Coarse older fanglomerates on the left are brought up by post-lacustral 

 fault. Finer fanglomerates on the right are horizontal. The contact is a 

 plane movement, but perhaps not the main fault-plane. Note lack of 

 bedding in coarse materials. Mohave Eiver in foreground (February, 

 1913). 



Fig. 2. Looking west and up Mohave Eiver, one mile southeast of 

 Field. Scarp of post-lacustral fault as emboldened by baekeutting of the 

 Mohave into the coarse older fanglomerates. In foreground recent waste 

 from coarse fauglomerates above overlies the fine fanglomerates.
