Fellow Surveyors:
I am performing a Section breakdown and have some questions concerning the breakdown of Section 20, Township 34 North, Range 3 West., Nez Perce County, Idaho.
A brief overview:
1) The original government survey of this section was performed in 1897 and was a completion survey to an earlier government survey dated 1870.
2) The BLM performed additional work in 2012.
3) All of the 2012 BLM monuments have been found and verified.
Enclosed please find:
1) Jn1230orgsur.pdf (the original 1870 Government survey of Section 20)
2) Jn1230blmsurvey1.pdf (the 2012 BLM survey around Section 20)
3) Jn1230blmsurvey2.pdf (the 2012 BLM survey around Section 20 blown up)
4) Jn1230blmsurvey3.pdf (the 2012 survey along with my notes added)
I need to establish all the positions shown with triangles.
Questions I have are:
1) Is point 7, east line of Section 20, half way on line between point 6 and point 8?
2) What is the northwest corner of Section 20, point 1 or point 2?
3) How do you set point 3, the N. ¼ corner, a lost corner?
4) How do you set point 13, the N. 1/16 corner on the west line of Section 20?
5) How do you set point 14, the C.N. 1/16 corner?
6) Are your answers listed or justified in the Manual of Instruction?
7) If so, please list the sections.
8) If not, do they come from another source?
There appears to be many good answers including straight line proportion, weighted mean bearings, weighted original acreages, holding fence intersections over procedure but I really need a reference to the Manual of Instruction or other documented procedure. Who wants to throw in?
I want to thank you in advance and if you have any questions please call or email my office.
Sincerely,
Terry T. Golding
1. No. Point #7, I believe should be set proportionally between Points 6 and 8. The GLO plat shows the South 1/2 of the NE Quarter to be 80 acres, so Point 7 would have mathematically been placed 20 chains north of point 8 by the GLO. You really need that closing distance by the GLO from Point 8 to Point 6 in order to proportion correctly. Is it in the notes?
2. It is Point No. 2. The original corner set at this location was Point No. 1. Then a surveyor set the "Closing Corner" on the east-west line. The original corner becomes the "Amended Corner". You will need the "Amended Corner" to correctly establish Point No. 13.
3. In many cases, the N 1/4 Corners of a closing section were never set by the GLO. There were different instructions depending upon the date of the survey. I believe the BLM would tell you to set it proportionally on line between Points 2 and 4. During some of the early surveys the closing corner was to be set by area taking into consideration the acres given in the government lots.
4. Point 13 was mathematically established by the GLO at 20 chains north of Point No. 12. You will need the entire distance between Point 12 and the Amended Corner at Point 1 and then proportion in Point 13.
5. At 20 chains north of the Center of Section, proportionally between Point 19 and Point 3.
I filled out my answers for 1-5 and had the same ones as J. Penry. The north 1/4 will be the only interesting number, I would like to see how all the geometry works before I would figure it out, but it shouldn't be too complicated. I'd only add that you should put the east-west lines on the curve and then it all follows along. 😉
On your posted diagram of Section 20 with the triangles & circles you show the North line bearing as East. The original plat (Retraced) has a bearing of N 89°23' W. The Dependant Resurvey shows this line bearing as N 89°50' W. Was there another plat prior to the retaced North line with a different bearing?
Also, what about the field notes for more clarification of the various surveys to better define what was supposedly done.
