I looked around at the high point for a while where one would think the benchmark would be, to no avail. Having seen pics of it before I knew there was one, just ended up not being at the high point. It's a little west of the high point down the ridge line a bit, located near a small rock ring / wind break. Closest GPS coordinates I have are N34° 17.214' W117° 39.279'. If you copy/paste those coords into Google maps and zoom all the way in you can see the rock ring to the west a bit. Its right in that neck of the woods.
Just for fun, I looked up the coordinates. Links:
