San Andreas Fault, Part 6: San Bernardino
GALLERY: All San Andreas Fault photos in gallery format
After descending the mountains from Cajon Pass, the San Andreas Fault cuts through the northern edge of the San Bernardino metro area. The fault zone crosses hundreds of streets, washes, power lines and residential backyards. The straight-edged foot of the mountains marks the location of the fault trace, making it easy to locate visually.

It is here that the fault begins traversing the San Bernandino Mountains among Little San Gorgonio Peak. There are no public non-4WD roads available to access to the fault trace in this stretch, so we'll jump on I-10 and head east around the mountains. As we do, we'll get a distant view of the fault zone in the high terrain: |
