Maacama Fault - Willits, CA

Traveling north through Willits, CA with coworkers, we stopped in town to view the slow warping of city streets due to creep occurring along the Maacama Fault. We stopped to take pictures at a vacant bank parking lot, where shearing forces from fault motion were clearly displayed.  A crack in the pavement ran from the southwest corner of the bank northwest across the drive-through section of the property, and then continued north-northwest across the remainder of the bank parking lot, where it exited the property beneath a fence.  Slabs of concrete used as a pseudo-curb along the north section of the parking lot where shearing away due to 6-8 mm/year of fault creep.  The previously mentioned fence on the far north side of the property also showed signs of warpage.  Pictures of the fault are displayed below.

Slabs of concrete breaking apart and being carried toward the north due to 6-8 mm/year of fault creep. Note the cracks in the parking lot pavement, which offer another marker for the fault location.
