Closing on a Standard Parallel (PLSS Question)

The image you posted cut off the top line of the course which likely tells the whole story. From what is stated, it appears they were running (North on a random line?) between sections 2 and 3, recorded the falling of 38 links east of the corner, corrected over to the found corner and ran "South ... East" on the true line.

A typical closing on a standard parallel would have run North (or, parallel to the east twp line) on a true line to the intersection where they would have set a closing corner and recorded the falling.

A big clue is that they didn't set anything 38lks east.

It looks to me from those notes that they are holding the existing monument as the corner and adjusting the line back south and setting the 1/4.

What does the plat show?

JB, I think you are exactly right and this is not the normal procedure, but secs. 3-33, 3-34, 3-35 give the reason that this was done.

Rectangular limits, as explained was the reason, and the resulting bearing of the true line and the 38 links were within both limits, therefore no double corners were needed.

The way I see it!

How so?

Would be good to know what the field notes say just above where you cut it off. What is the initial course run and does it say random or true? I am assuming it says "north on a random line".

One thing that strikes me is that they set a temp 1/4 corner, indicating random line with the intent of correcting up and running true.

That, plus the statement of "From which I run S 0-16 E seems to seal the deal that he corrected up and ran true line from the standard corner. 16 minutes does appear to equal the expected correction, and in the right direction.

I'd have to say he reported the true line to be from the standard corner, not the point of initial intersection.

I'd have to research to see if a limit of tolerance was applicable. Even if so, 38 links seems to be too far but perhaps the instructions for that time and survey provided for correcting up if within that close of a closing?

JB and Keith are in the boat...others like to swim around for awhile ....others think they can walk on water but I don't see them anywhere....

"From which", or I think that was written tells the tail. The other surveyor was correct.

Good explanation.

I see the 73 manual gives 21 minutes as the angular limit and 25 links per 40 chains as the distance limit.

I am curious if these rectangular limits have changed over the years, or have they stayed the same?

What does the plat show? Does it show an offset to the C.C.?

Apparently Keith that's what happened (no double corners). My "copy of a copy of a copy" of the 1872 (1874?) manual is long gone. I don't know off the top of my head what the rect. limits were back then, but apparently greater than that.

The NW corner of 3 fell 60 lks. east of the SC at the SW of 34, and the notes reflect the same as this corner. Apparently no closing corners were set.

Paden,

Several of the old manuals are part of C.A. Whites History of Rectangular Surveys available on the BLM website @

http://www.blm.gov/wo/st/en/prog/more/cadastralsurvey/cadastral_history.html

I didn't look through to see if the manual you're in need of is in it, but it likely is as there are a number of them there from teh 1800's.

Had they not moved over to the existing section corner, there would have been notes about setting a corner monument to be the corner common to Sections 2 & 3. Also, there would have been no need to return on a different bearing and correct the location of the common quarter corner. Therefore, they must have accepted the existing corner on the Standard Parallel the same as is common when closing on a township or range line previously established during the same survey realm.

I'm not sure White has anything between 1855 and 1881, but Google Books has the 1871 Manual as a PDF.

Cheers,
Henry

Wished we coulda got the T and R, the plats and notes to see if I was in the boat or outta boat!
