Log Description

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. 

About Carrizo Plain National Monument

This remote monument, traversed by the San Andreas Fault which has carved valleys, created and moved mountains, and yet up close, is seen in subtle alignment of ridges, ravines and normally dry ponds.  Prominent features on the monument include the white alkali flats of Soda Lake, Painted Rock, vast open grasslands, and a broad plain rimmed by mountains.   When conditions are right, numerous wildflowers can carpet the valley floor; although short lived it can be breathtaking.
