DISTINCT ELEVATION OF SANTA INEZ AND OF THE CORDILLERAS. 
meet near one focus, the San Emilio district, and conspire to form this elevated region; or rather, 
as has been advanced before in this report, the radiation of the lesser ranges is from the south, 
diverging more to the west as they proceed north, each range a little more west than its prede¬ 
cessor, until the direction of the Santa Barbara hills are obtained. 
In alluding to the Santa Inez mountains it has been shown that they are uplifts of volcanic 
rocks upon an already elevated land ; land previously upraised by granitic masses, and the ele¬ 
vation of which originally lay northwest; hence the range is a series of short links which lie in 
“ echelon” to the whole range, the dip being southwest and northeast, and occasionally south¬ 
east and northwest, according to the position of the volcanic rock. The influence of the Cor¬ 
dilleras, therefore, as an elevating agent, does not extend to the Santa Inez range ; it has neither 
the axial rock nor the dip to correspond to such a supposed cause. The true termination of the 
Santa Inez mountains is on the Santa Clara valley, and the upheaving causes come from the 
northwest, and not from the southeast, as is supposed by the State geologist of California; and 
to call the Santa Inez mountain the San Bernardino range is to confound things that have no 
necessary connexion.* 
The volcanic rocks which have elevated the Santa Lucia, San Rafael and Santa Inez moun¬ 
tains run in a direction which would enter the Cordilleras in the southern portion of San Diego 
county, near the boundary line, and from that north to San Bernardino. This range they 
appear to traverse along its western edge, and do not in any place cross over to the eastern 
side ; they elm he traced at some distance from shore near San Juan Capistrano, San Luis Rey, 
and San Pasquale, at positions from 300 to 500 feet above sea level.
