Above the beds classed as Temblor there is a gypsiferous 
clay shale 250 feet in thickness, overlain by 50 feet of coarse 
gravels and conglomerates. 
From the Cantua creek the Temblor beds have been fol- 
lowed southeastward to the vicinity of the producing oil wells 
and to within a short distance of Coalinga and to the Jacalitos 
creek. A large part of the strata formerly placed in a suc- 
ceeding group has been found to belong to the Lower Miocene. 
The “Reef Bed” of the former paper is properly a part of the 
Temblor, and has yielded, on Sec. 20:
