TERRESTRIAL DEPOSITS OF OWENS VALLEY 



723 



sands in Waucobi Canyon, described, by Walcott, 1 and in the vicin- 

 ity of Haiwee described by Turner, 2 Fairbanks, 3 and Campbell, 4 

 even though such mention leads beyond the confines of the Inyo 

 Mountains. Both these deposits were seen by the writer, and they 

 are here discussed in so far as they may be used as a type of lacus- 

 trine deposits. Walcott 5 and Spurr 6 have interpreted these deposits 

 in slightly different ways, but both agree that they are lake deposits, 

 and as such they will be described. Discussion as to whether they 

 record great recent uplift of the Inyo Mountains, as according to 



Fig. 13. — Unsorted material of the Sierra bajada 



Walcott, or were deposited in a deep, widely distributed lake, as 

 Spurr contends, is not in place here, though such discussion is 

 given in the unpublished part of the thesis.

Waucobi Canyon, or the Waucobi embayment as it is called by 

 Walcott, is a re-entrant in the west face of the Inyo Mountains a
