Identification of active faults in enlarged stereo models of Skylab S-190B photographs

Most of the physiographic indicators of recent movement known to be present along the Indio Hills segment of the San Andreas fault zone can be identified on enlarged Skylab S-190B stereo photographs. These include offset streams, beheaded streams, offset fans, shutter ridges, linear valleys, scarps and vegetation anomalies. Where physiographic indicators of recent movement are present, the S-190B system affords the necessary resolution and stereoscopy for distinguishing activate from inactive faults.
