The San Andreas fault zone, as it is exposed in San Gorgonio Pass, is distinguished by several unusual features. Among these are the absence of typical rift topography along much of the supposed trace of the fault (Lawson, 1908; Vaughan, 1922), a lack of horizontal stream offsets, an apparent abrupt major change in trend of the fault, and the absence of intense earthquake activity associated with the fault zone. Further, seismic strain-release studies (Dehlinger, 1952) have indicated thrusting, rather than strike-slip faulting in this one segment of the San Andreas system.
