Cracks on far side of wash; called 'en-echelon' breaks where they step sideways.

Southeast of maximum displacement site. Here we see 3-4 meters of right-lateral slip have offset a ridge and created a 'shutter' ridge blocking flow in the dry creek channel. The white vertical surface is the fault scarp.

View downward onto vehicle tracks crossing the fault at a high angle. One can see 2.5 to 3.5 meeter right-lateral displacement of the tracks.
