Our worst boundary nightmare has come true for me. Of the 21 corners on the site I found one (1). There is agreement the current section corner monument has moved eastward 0.3 feet since 2001. The reverse-curved road centerline on the east side of the site was monumented after construction by a surveyor known for putting them back in the wrong place, sometimes by a foot or two, which is why he surrendered his license. Brand X did the subdivision plat and his tie to the centerline is obviously wrong by about 49 feet. And my metal detector died.

That takes the cake!
I got one of those going, only the battery for my base went boobies up. Two different DOT surveys disagree on the section corner I need, in the middle of one of the busiest intersections around, and every other corner I need, gone.
Just because I'm paranoid, doesn't mean they aren't out to get me.
Knock on wood...

Alaska DOT ties to PLSS corners are problematic. The last time I tried to use one the result made no sense. I ended up finding the original corner using the distance called for from the road in the 1942 GOO notes. Then I realised what had happened. The 1965 DOT call was to a pit dug by the GLO in 1903. The problem was that survey was canceled in 1940.
An interesting development. Those record of surveys that show the section corner monument is in the wrong location by 0.3 feet - are wrong. I dug up the old Pima County rebar reference monuments from years ago and the section corner is were it has always been. A good shovel is a surveyor's best friend.

I was thinking "You be screwed..."
I once retraced a survey... Where the surveyor had pulled out his own markers!
(he'd blundered by 400', and was getting in trouble, so he pulled out his own markers, btw, in section 6)
I wound up retracing all of his work in the area. No monuments. Except at one end. And, a road, so, i had the road, as a natural marker, and used it to discover his 400' error. Quite a mess...

I have quite often found WSDOT's ties to PLSS corners (my employer, no less) to cause considerable cranial agony. This is especially true with older R/W plans in comparison to newer ones... Just yesterday I examined a 1935 R/W plan where four ties to a section corner, 1/4 corner and a center of section mon were given. The current (1987) plan also has ties to the same corners; the closest agreement was nine feet. BLECCH!!!!!!
The only superior evidence is that which you haven't yet found.
I've met and worked with many former highway surveyors and their main instruments were an "Arkansas 90", "eyeball line" and "toe placement".
Every one of them were excellent at measuring distances.

This was exactly the source of my most recent facial twitch. My project involved doing a design survey in a heavily developed area where every single bloody corner had been wiped out by landscaping and a DOT road project where the only monuments to go back in were centerline monuments referencing project centerline, none of aliquot part and subdivision corners were replaced or were referenced to the centerline, however the ROS DOT recorded did list coordinates for what they had recovered, in meters in an early LDP projection. ROW takes up the wazoo. Only the section corner remained, underneath a highway overpass, in the middle of an intersection with traffic coming from 8 directions. A second DOT project done some 20 years later in a completely different LDP overlapped the first by only the section corner in the intersection. I was able to reverse engineer both projections with a high degree of confidence, but the section corner in question has apparently now moved 0.6' and no, I have no plans to try and occupy it.
