 eastern end of a great, sinuous, double-curve of trends

 This, however, is all vaguely conjectural. 



There are also sinuous, east-west lineaments in the 

 summit of the San Bernardino Plateau which sharply 

 bend or drag to the southward at the eastern side of 

 that feature, having been there cut across by the 

 north-south extending Whitewater Fault. 



Excellent cross-sections of the successive faults and 

 folds of the Ventura and western Los Angeles regions 

 are given by Kew in a Bulletin No. 753 of the United 

 States Geological Survey.
