Evidence of a fault? Near Bat Cave Butte (2088)

I spotted this by chance. Clearly water runs through it, but it's not taking the shortest route downhilll. It's about 30 degrees away from straight downhill. It is not parallel with the San Andreas fault, which runs along that band of green near the ridge line. It's not a pipeline. There are a couple of those in this area, but they run parallel to the San Andreas fault. You can see the route of a pipeline lower than the San Andreas fault, just above the lower band of green. This line could be a fault branching from the San Andreas. I'll go back and inspect it more closely with an expert some time.
