10' 1" Under Sidewalk
Note on an 1897 plat. I'm having a hard time envisioning the circumstances under which this came to be.
Is that a water frontage? Monument 1" below natural ground then 10 feet of fill brought in.
Better get Bill out there with his metal detector.
Wasn't the entire downtown Sacramento area raised up to that degree after flooding? What is the map location?
Very thankful that he specified the 1" if I have to dig that up
Is that a water frontage?
Yes, the Sacramento River is at the bottom of the image. I can maybe understand how the monument got buried that deep, but I'm having a hard time believing that anybody dug it up without benefit of a backhoe and with a sidewalk on top of it.
Wasn't the entire downtown Sacramento area raised up to that degree after flooding?
Much of it, anyway. But this is on the other side of the river, in what used to be the Town of Washington (now part of West Sacramento).
Make sense now?
Digging down 10 feet (and an inch!) doesn't make sense to me, especially given the location, the era and the surveyor. (I've retraced quite a bit of his work, and it's generally pretty good, but not generally heroic.) There must have been something unusual about the conditions at the site to warrant the peculiar recovery.
The wooden walkway was elevated 10' in the air snd the notation was a measure down?

did you find anything?
It doesn't affect the block I'm working in, so I didn't look for it.
Maybe from previous work he believed it to be there. But the depth to the inch implies he saw the gun barrel and the sidewalk at the same time.
So a distorted version of Occam's Razor leads me to believe the sidewalk was raised with access beneath it so that the gun barrel was reasonably easy to recover and easy to measure up to the sidewalk above.
Or alternatively, he carried trig elevations on all of his work and when he went to stake this point out again he got a cut 10.08'
Did they do stake out in the late 1800's?
My vote is with MightyMoe. At the time, the gun barrel was directly below the raised span of the sidewalk that may have been part of some sort of extensive deck along the bank.
