After 4 days of calcs with a side of nontangent curves, and 3 days of breaking down a quarter section in traffic while teaching the new guy the inside secrets of traversing by resection by robot, we found all six rebars with cap, good to a tenth. He has a steady hand. Today I introduced the idea of one handing the rod and running the data collector with the other hand. Yeah that plastic thing broke years ago and the rod actually plumbs a lot faster without the data collector attached ever since 2014. I did try a fixed-length-string plumb bob hung from the prism and the horizontals tightened up but the verticals gained about .04 plus or minus.
The new guy got it today. The stoke. He got the stoke after 3 days of hearing about how we were flying this in from the outside from the quarter section because all the closer monuments were destroyed when the road got rebuilt. The stoke was when he got to stake for the calc point, then wave the metal detector around, then dig for and then CLANK find the late 90s monument with the shovel. Then do it five more times. Flawless victory.

Outstanding!!!
Excellent!
This reminds me of a time I was helping recover a section corner with @holy-cow near a landfill back home. It was COLD, the wind was blowing (weird) and the asphalt was frozen. The rock bar we had was making little gains and then someone (I won't say his name but his initials are @holy-cow) grabbed a small propane torch from his vehicle to help speed along the process. A few minutes later, tah dah! There she was, a half inch iron rod with a little piece of flagging on it.
Granted, the corner we recovered had been recovered by others previously but OP reminds me of this story. Carry on!?ÿ

The stoke.
Hopefully you taught him your calcs ended up being within a tenth of the actual corners (the found monuments)...???

And pass over the opportunity to fuel the fires of pincushion fury for another 50 years?

"These are original monuments, so if there is any error, it is our error, that we brought here, by doing a more perfect survey of an imperfect original."
I think it may be a research failure. Dad usually did recon on the actual site, before surveying the section. If you'd had more info, maybe you'd be done in only one day.
(Of course I'm blowing smoke... I don't know that you record your plats in that area.)

I will admit that I thought the same thing...if you found the six monuments to start with, no need for the traverse!
Participated in a Lunch and Learn hour today discussing thinking in PPM's.?ÿ The difference between precision and accuracy was a key topic.?ÿ How closely one agrees with someone else's work may be precise yet not very accurate.?ÿ Maybe you just made nearly identical mistakes as the first guy.
Noted that one of the other 45 participants was Jimmy Cleveland.?ÿ Don't believe he has posted much here for quite some time but was very active in the past.?ÿ Memphis area, I think.
I haven??t heard that name in a while
Jimmy posted once last December and once in June. He used to be quite active here.
@dmyhill if you don't do the traverse, how do you know how the found monuments relate to the controlling corners?

Yes. Otherwise I would have been digging a foot north.
Hey guys, I am still around. I have just been crazy busy. I am now working for a firm in Memphis, and don't have the free time I used to have. I need to get back on here a lot more.

Couple days ago, we found the 1980-or-earlier copper tack in lead, in the concrete roadway surface. Never would have found it without having a stake-to-it coordinate calculated from the C/4 and one of the other quarter corners. Nearly invisible, looking like any other chunk of aggregate in the concrete. The top of the tack is worn away and flat now.
Nate suggests that this job took "too long" for a lack of research, and I ponder that. I did do a walk-around of the quarter section, looking for those tacks-in-lead in the roadway as cars whizzed by. The calcs took a long time because the producer of the footsteps I was following is a third generation surveyor, now retired, who never liked the Survey Recording Act and basically refused to put anything on a survey that could be incorporated by reference to a previous survey. My calcs required 4 other surveys and a county section breakdown. Other surveyors apparently turn down work or price it accordingly when they see it is in one of his plats. I did not expect to find the corners I found, simply because on the face of the plat he never mentioned setting anything at the corners.

One time I had a 1960s survey, set a concrete nail and tag in asphalt for a centerline point. Get there, cracks all over the place, I think no way it??s there, walk over there, wow it survived, amazing.
