Wallace Creek

Here you are standing on the San Andreas Fault. At this location it runs northwest to southeast a the base of the hills. At one time Wallace Creek drained straight across the fault, but movement by the San Andreas Fault has offset its drainage course, with the downstream segment about 430 feet northwest of the upsteam segement. This is one of the best examples of stream offset across a fault in the world. An interpretive trail is available to learn more about this portion of the San Andreas Fault.
