Found it at 18:15. I drive by this one quite often and have seen more than one surveyor set up on it. The brass cap is in a covered well and in good condition. The listed coords were right on - only 10'-12' off.

The benchmark in the well with the GPSr.


The well relative to the Witness Post. Note the '06 QF' designation on the post. The view is to the northwest.


This shows the proximity to the southbound on-ramp from Golden State Boulevard just south of the Ashlan Overcrossing. The view is to the south.

As far as I can tell, this benchmark no longer exists. The coords are in a parking lot in front of Klein's Truck Stop Diner. There are no structures (let alone a school) nearby matching the 1953 NGS description. The described Herndon Siding sign, the Cities Fuel Corp. building, and the former Herndon School are all gone. Klein's Truck Stop Diner is here now.

The described Herndon Siding sign, the Cities Fuel Corp. building, and the former Herndon School are all gone. Klein's Truck Stop Diner is here now. The coords for the benchmark are fairly close to the sewer manhole about 40 feet in front of the diner. (If you look closely, you can see the manhole in the picture.)
