Proportioning Lost Corners

Kevin Samuel · 2013-01-04T00:41:00Z

I am having a disagreement on the calculation of a position of a lost corner to be re-established with a co-worker.Record Calls on Section line between Section 24 and 25 circa 1880 (no weird stuff here pretty cut and dry)....East on random line bet Secs 24 & 25 v19d30'e40.00 chs set temp 1/4 cor79.78 chs intersect Tp line 38 lks N. of cors89d44'w on true line39.88 chs set basalt stone 12x9x6 in mound with pits for 1/4 sec cor79.78 chs sec corWe have the section corners and need to reset the 1/4 corner. The next psuedo-retracement of this line was by the County Surveyor in Feb. 22, 1906 when performing a survey for the establishment of a new county road who states he finds the 1/4 matching record size and with legible marks lying loose on the ground. Read... corner has been disturbed since sometime prior to Feb. 22, 1906. I say psuedo-retracement because the County Surveyor is generally running along section lines, but does not call to or find the NW or NE cor of Section 25. Instead he just keeps chugging along setting milestones (stones marked 1M, 2M etc).No remaining evidence of stone or pits or occupation lines for that matter. The area is heavily farmed irrigated land, think very large pivots and wheat fields.So here is the disagreement...I contend that we must proportion against the record. Note the original 1/4 corner was not established at midpoint. The midpoint location for the 1/4 corner would be at 39.89 chs, not 39.88 chs.We are talking about a difference of one link, even in the record and as it works out also in our re-establishment.No special instructions, true line notes agree with plat, etc. etc.So is the answer:A. proportion against the recordB. re-establish 1/4 corner at midpoint of retraced line

that'd/funny. I'm sure you made the best determination for your situation. But it reminds me of a survey I did.

I was retracing a road right-of-way and found a BLM monument in the roadway. They set (in a dependent resurvey) a new monument in 2001. I pulled the BLM notes and found that they used the east-west proportional distance for the e-w position, but the center of the road for the nort-south position. The problem was, that the center line of the road was originally 15 feet north of the section line.

Gotta-look at all the data I guess.
