Geology of Carmclo Bay.

represents the continuation seaward of the fault valley in which the 

 San Jose first began to flow. 



The other submarine valley to which we refer is that of Monterey 

 Bay. This is one of the largest, most important, and most critical 

 for this discussion along the coast. This, also, seems to be a struc- 

 tural valley, and to occupy a great synclinal trough or depression 

 in the Monterey shale. This formation occupies the coast in the 

 vicinity of Santa Cruz, and it has been examined for many miles 

 along this part of the coast, and found to have a constant southerly 

 or seaward dip at low angles (from 5° to io°). At the head of the 

 embayment near Pajaro Canon the same rocks have a westerly dip 

 at somewhat higher angles, and at Monterey, on the south side of 

 the bay, the same formation dips northerly at an average angle ot 

 about 5 . These facts indicate clearly a synclinal structure for the 

 Bay of Monterey. Thus, two of the submarine valleys appear to 

 be structural features, and the others will perhaps also be found to 

 have a similar origin.
