I have a corner position I need to analyze- some re-established it based on Record Information from Existing BTs- but it appears (to me anyway) to be Jacked- I have SPC on their set mon. plus the center of three of the record BTS
SE tree is now a 48" Ponderosa Pine stump. has evidence of the very bottom of a hacked blaze at right diameter for the 1894 record- species is correct- bearing kinda ok- distance not so good. really poorly described in previous CCRS
SW Tree in now dead & down- 22" DBH ponderosa Pine- scribed face is rotted out- nice defined stump hole- species correct- bearing and distance Meh-
of the 2 north trees- only one exists at anything close to original distances North east is 16 links Northwest is 22 links 21" standing ponderosa pine with nearly healed blaze is at 13.5' in the NE quadrant from the current Mon.... scribing is visible deep in the blaze, but not readable.
my hopes are to determine a good position from the corner that readily id's the north tree with out having to open it up to try and read it- then look for the remaining tree/ evidence in an improved search pattern.... I'll try to post pics when I get a chance.....
???? what you use for error estimates for bearing and distance? 1894 Solar compass- corner falls on a 45% slope N/S

I wouldn't worry about that much. I'd get a solution and look at the residuals. If they were of similar magnitude and reasonable I'd then set the error to suit the results.

Why would you fight the computer model instead of work it from the ground. It sounds like you have enough to locate the point pretty close and then work the other area out. Seems like you could reset it in the field and move on. At least that's what we do with that scenario.
The field geometry didn't work very well due to the steep slope and tree cover. I'm hoping to office model yield validate somethings and make them more readily apparent than in the field...- I'm most likely going to still need to take a chainsaw up there and open up the one tree to read the scribing. the SE BT is the real flyer- +/- 30 in distance-
Any chance the distances to references were measured on the slope? Could be something to keep in mind.

I wandered up to a corner recently with one reference being a 60d nail in a tree 3.1 feet to the north of the corner. There is no tree north of the corner. But, there is one directly east of the corner with a 60d nail precisely 3.1 feet distant.
things took a different twist yesterday- I contacted the company that did the first corner rec- they supplied me with their field notes from the work.....( read the first corner rec closely- it gave me more questions than answers) the notes clear up some things but don't really settle anything....although the blunder is probably smaller than I first thought..... More later- gotta go feed the kid....

[sarcasm]GLO set 60d nails in your neck of the woods?!?!?![/sarcasm] 😛
Sure............Gerald Lee Osborn or was it Gary Larry O'Leary?
You're a smart patootie.
The vast majority of our original corners were stake and pits. The vast majority of said corners were obliterated (or remonumented) during construction of county roads along section lines in the 19th Century. Nearly all of the remainder corners were monumented by limestones or sandstones. Many of those were lowered or simply covered during road construction. Those are the ones we find from time to time by using a backhoe to excavate. I can count on one hand the number of original corners of which I am aware that were an "X" scribed into bedrock or a boulder. As for bearing trees, let's just say those are only slightly more prevalent than chicken's teeth. There were very few trees outside of river/creek channels in this area of tall grass prairie noted for vegetation tall enough to require a man to stand on horseback to see a significant distance. Sort of a problem for the old "line of sight" method of progressing in a straight line. Nothing like a convenient prairie fire to simplify the work of the surveyor.

How about those zinc pots?

First, I would haul a saw up to the tree at 99 ft., ori. is 100 lks. and make SURE, scribing, its an original BT. The hack mks. could be from the 1900 resurvey looking for the corner. Is the 1986 pipe that remonumented the 1975 restablishment of the ori. corner still there? And what gets the most weight in my book is the 3 different Land Surveyors, 1975, 1986 and 2003, who have weighted the evidence on the ground and have accepted the same position for the corner. There is also 3 surveys built off this corner, one thats been around for 40 years. When I was in the field and came apon a remonumented original corner I always played King of the Hill, the first person there was king of the hill, and I had to come up with overwhelming evidence of another position before I rejected a remonumented original corner.
Just my 2 cents worth.
headong out with a chainsaw and an increment bore..... more later.
So I'm pretty sure the northerly tree is NOT an original BT. I used an increment bore on it, then opened it up- the rings say that it's +/- 107 yrs back to when it was about 2 Inches in diameter. 1908- The originals were an 18" pine if it's the NE tree a 12" pine if its the northwest tree- and was even farther back in 1894. My best guess is that the ACM timber people marked new trees in the 1955 era- you can see "R23W" in the opened blaze but prior surveyors had hacked into the tree and pretty well screwed up the rest of the scribing..... I'll try tomorrow for a better picture in different light.... 
I patched the hole with eclipse gum.
the tip on using the straw for safe-keeping of the core was from a seminar years ago from a forester name Parish.
The tree in the SW quadrant that has been identified as a marked tree in all 3 ccr's is now dead and down- the blazed face was up and squirrels have made a nest in the rotted blaze. I sawed thru the tree at what would have been DBH- it was 18". I counted thr rings on it and ended up somewhere around 140. So it's a possibility, depending on how long it has been dead/ an unknown since none of the ccrs mention condition of the tree.- Here are 2 pictures of the round I sawed out.
the light line without dimension is center of tree to the supposedly blazed face...
here's a close-up....
the black lines are to help me keep track of my counting and to estimate size. - Supposedly it was a 10" pine in 1894.
So- I said I was given an opportunity to look at the field notes for the 1975 corner rec.
it offered the following-
they found a "dislodged stone" with 2 grooves and 4 partial grooves "8-10 ft from the tree with location poster" ( the tree I cored)
found 3 trees with "slashes and markings"
they assumed tree I cored was the original NW BT and "Slope-chained 14.52 feet" 13.5 horizontal at N2W ( by transit)
from the tree I cut the round out of- they "slope-chained 37.62 feet" for 34.6 horizontal.
then re-set the stone....
.
what this does is move the stone about 3.5 feet FURTHER down hill than it was found....
.
they also note that they set the pipes/caps on 10 offsets from the position, but this info never made it to the ccr.
As far as my Star*net attempt- I started it a bit but haven't gotten too much into it.
FWIW- the position falls about 54 feet (north) long N/S from record- per other COS' the distance to a fnd stone at the 1/4 corner to the north is 67' short...
tomorrow- I want excavate the monument and look at the stone. -Supposedly, it's buried alongside the pipe. -I did find another stone 18"x16"X8" in the vic. that looked like it may have had some grooves on it- but not supper definitive.
