Miscellaneous Request:
Does anyone have a photo of the Mt. Diablo controlling monument across the bay?

Do a Google image search of the Mount Diablo Initial Point and a lot of really good photos come up.
Oh no...a pincushion at the initial point for California?
"Later research in the 1980s suggested that the copper bolt head, left exposed inside the center of the column, was actually from a coast and waterways survey started in 1852, and that the 1851 public lands survey mark, a small rectangular depression in the rock summit, is actually three feet northeast from the center of the pillar, a point that is now under the floor of the museum. If this is true, then the column, and the axis of the entire building, is off by 36 inches."
(sorry for the hijack)

I was gonna say if you're not sure then I hope you're in the memory unit of an assisted living facility. 😛
3'? Heck, those are practically on top of each other. The San Bernardino Meridian has 3 Initial points, one set in 1852, the 2nd set in 1892, and the 3rd set in 1907. The guy in 1892 apparently didn't make much of an effort to find the point set in 1852, and the guy in 1907 seems to have just been an expert measurer.
The drawing in C. Albert white's Initial Points of the Rectangular Survey System (p. 257) shows the three points to be more or less collinear along the baseline with the 1892 IP being 13.786 chains East of the 1852 IP, and the 1907 IP being 9.348 chains East of the 1852 IP. Townships to the North originate from the 1892 IP, and townships to the South originate from the 1907 IP, which was originally set as a closing corner of a multi-township traverse.
The original IP for the Humboldt Meridian was apparently destroyed at some point and then replaced. By later measurements, it is suspected that the newer (and existing as of now) monument is about 2' from the location of the original.
[sarcasm]With all of our initial points having been pincushioned, it's a wonder any two surveyors ever agree on any point in the whole state![/sarcasm]

And the Coit Tower photo is awesome. Where is that PLAZA monument? I'll have to visit that next time I'm in SF.
That is about a half mile west as the crow flies of the town of Parkfield in southeastern Monterey County. LS5145. I don't know him but his monuments are right on. Distance from NW corner section to east quarter corner...0.2' but that's an RTK shot up against a utility pole. The pole is new so the old pipe may have moved a little...besides this is Parkfield, that place is moving anyway.
To clarify...the red cap is LS5145.
Pincushion means you are in Colorado - they don't happen anywhere else, right?
