Paxton was the County Surveyor. Walker was one of my predecessors here at CDF (his work is very accurate). Hanby (a private surveyor) set a 1" iron pipe (bottom of the page) by single proportion which apparently spawned a law suit between west and east owners because the original quarter section corner (top of page) was found by Paxton. Paxton's corner prevailed in the litigation.
Paint went kind of haywire. This is an excerpt of Walker's map. Note this is before the Final Order of Condemnation into CDF so the north-south heavy line is not correct. The final description calls for the north-south centerline which is about 16' west of Edmond's southwest corner. Edmond's Deed does not call for the centerline leaving our common predecessor, Whitlow, with a strip between Edmond's west boundary and the north-south centerline. It is a strange situation:
This is the original quarter section corner Paxton found:
The brass topper set in 1970 in place of the 4x4 post and 3/4" iron pipe that Walker found in 1958. It looks like it is set in a 1-1/2" iron pipe. LS2780 shows it as found on a 1976 Survey for a nearby reservoir.
This is better. North is up.
What a great post! All newbies and oldies should read this. 🙂
Edit: and everyone in between.
Excellent example - should be an NCEES exam question.

I'm sorry...maybe I'm just old...but someone usually has to pay me to wade through things like that!

Hell, I'm older than you. The article Dave posted grabbed my attention and I had to go through the whole thing. It also illustrated other surveyors can look but can not "see". An ability that only seems to come with experience, or from a damn good mentor.
All of us have F'd up at least once. 😉
Have a good 'un and oil the cellar doors and if Toto don't make it, just throw 'em on the grill. :p
Hanby should be Hamby per a look up of LS2843 on the BPELSG website but Walker misspelled his name thoughout the notes 🙂
The 3/4" iron pipe south of the distance 164.16' (south of Reservoir Take Line) is lying on the ground out there near a fairly fresh power pole. I staked out where it should be (in among the Manzanita) and it looks like the power company scraped about a 20' diameter circle around before they drilled for the pole. There is a lot of lava cap in that particular spot so they probably needed a pretty serious drill rig. I have all the other pipes excepts the 1/16 corner by Hanby (it may be under a house), the dot on the right (which per the notes is a 1" iron pipe up 2.5' and was a lease corner). The 3/4" iron pipe on the take line is bent but we were able to find the "gazinta" and the 2" iron pipe is intact. The water was right up to its top, I had to get some logs to make a sort of platform so I didn't get my feet too wet. Walker did a traverse from the 1-1/4" iron pipe P.O.B. east to the pipe east of the take line then northwest through the 3/4 and 2" iron pipes then over to a stake by the 3/4" (now on the ground) then down to close. So I'm going to see how that fits with my control in the area, maybe get a better fix on where the 3/4" iron pipe was located. I have more reservoir monuments running northwest, he apparently just used a record angle to get the intersection at the north point. Maybe no one cared too much because of the lava cap (no timber) because they didn't set a monument at that point.
The 2" iron pipe is down in a swale. Walker said the swale was running, we found the swale with running water and the lake backed up to the top of the pipe:

The pipes that Walker says are at the corners of Edmond's property aren't called for in his 1953 description. They fit distance very well, within a few tenths of record.
I'm not sure whether I should accept them or not?
Not a record monument!!! Blasphemy! Throw 'em the hell out and set yer own!!! Who gives a ratz azz if the owners have been relying on them for half a century...
/sarc/
Is that 2" pipe measured as I.D. or O.D. ?

Ha ha...
Nominal Inside Diameter.
Attached are the relevant pages from Walker's field notes as to where the 3/4" iron pipe found lying down on the job was located.

Those are some sexy images.
Notice they didn;t have to specify I.D. or O.D.
Everybody back then knew how your suppose to measure a found pipe monument.
Some temporary summer help kid might have measured the outside diameter...but the crew chief probably knew better than take his word on it.

Why do you think they were slope chaining on such flat ground? Jp

I couldn't say.
Why did Walker set Traverse Point #16 only 0.16' from the 3/4" iron pipe (that got knocked out)?
The Butte Unit Forester has his office at this facility; a pretty nice place to have an office. I wouldn't mind being stationed there.
This is Walker's traverse from the 1-1/4" I.P. P.O.B. east past Hanby's 1/16 corner to black dot at the fence corner then northwest through the 3/4" I.P. and the 2" I.P. to the 3/4" I.P. (knocked out) then south to the P.O.B.
I have it minimally constrained at my coordinate for the P.O.B. and the bearing south to Edmond's S.E. Cor:
