RECAPITULATION 



The Salinas Valley in Monterey county is a trough that prob- 

 ably holds a great deal of water. In its northern part from near 

 Riverbank to some point between Chualar and Salinas it is cov- 

 ered with talus washed in from the mountains. 



Pliocene and Miocene sediments 

 underlie this talus though to what 

 extent is uncertain. Going south- 

 ne ward the Pliocene beds rise from 

 beneath the talus at about River- 

 bank ; and from east of Kings City, 

 to the southward, they form an

at two levels in the angular granitic ls probably tributary to the under-

In the drainage area of the San Antonio and Nacimiento 

 creeks there are also Pliocene gravels which are indirectly tribu- 

 tary to the underground water supply of the Salinas Valley. 



It seems probable that deep wells put down near the western 

 margin of the Pliocene terrace between San Lucas and the San 

 Luis Obispo county line may yield considerable water, perhaps 

 artesian. 



Slightly salty water has been found in wells in the terrace 

 beds above the valley, though there are folds lying between 

 these bore holes and the valley (Fig. 6). 



It is possible that artesian water may be found in the region 

 of the San Antonio and Nacimiento creeks, but not enough 

 detailed work has been done there to warrant any definite con 

 elusions upon the subject at present.
