This really doesn't convey the Calaveras Fault Zone. If you want to find out what the Calaveras Fault Zone is, I suggest going to the California Geological Society website (http://www.consrv.ca.gov/cgs/) to look at maps, and read text on this fault zone. I am not sure what this aerial photo is, or where it is located, but it is essentially useless. And, the Calaveras fault is not really part of the San Andreas fault zone. So, the San Andreas link is kind of useless.

Have a good day!
