I saw the remonumented but then there's the measure within .1' between them. Confused me. It sounds like you leave them both set or something.
I've found several corners similar to the pics MM posted, wherein the BLM retracement notes it plainly said they found the stone in place at the corner and they set the pipe & cap next to the corner. Therefore, the stone is at the corner and the BLM pipe is a witness. According to our statute, we are to replace the stone (which is the corner monument), and unless we remove the BLM witness pipe, there would be a pincushion - two or three (as in MM's 2nd pic) monuments where there really should only be one.
I understand what they thought they were trying to do, but when you have non-surveyors writing and approving statutes and pushing them thru the legislative process without accepting substantial input from surveyors who actually get out into the field, you get these unintended consequences.
IF I find a stone, with questionable heritage, I remove it, and study it, looking for an X or other scratches. Then, I usually set a nail UNDER it, and shoot the nail, and replace the stone.
IF it turns out to be the corner, through other evidence, etc, then I replace the nail with a rebar under the stone. But, the stone stays put.

I don't really understand why people mess with stones. If it is a rotten post or pine knot, then I understand perpetuating the corner. The stone, if called for, IS the original corner. It should not be moved or disturbed in any way. The stone should not have another pin set next to it, above it, under it or anywhere around it to possibly introduce any confusion. I think the only exception would be to use a cap that has "witness" stamped on it.
I only work in metes and bounds states, so I am unfamiliar with the manual. In metes and bounds states I think you should drill a hole in the top of the found stone and add a mag nail & washer with your LS number. That way, someone can pick it up with the locator and there is a visible record of what was held by whomever.
Many of the stones in the PLSS are now in the centerline of roads. In my county about 95% of those still existing are in the center of roads. We cannot allow the road graders to keep knocking pieces off or taking them out, therefore it is imperative to lower them in the same horizontal location.
That makes sense too...I haven't thought of that. I suppose that with good record keeping you could keep on top of it.
> As for: "Monuments shall be marked such that measurements between them
> may be made to the nearest one-tenth (0.1) foot." Who knows what goes thru the minds of those writing such idiosy. I'm afraid to ask the PTB.
[sarcasm]They must be referring to the size of the "dimple" you place on the cap. The dimple has to be less than 0.1' in diameter... Maybe the dimples on any two connected control monuments must be no larger than 0.05' so the cumulative effect on the measurement between them is less than 0.1'?? [/sarcasm] :'(

I have attached some photos of my style. I like to place my metallic monument underneath of the stone and document it. I hope that the magnetic quality of my monument will make it easier for others to find the stone in the future.
ORS 92.060 Marking subdivision, partition or condominium plats with monuments;
(4) A surveyor shall set monuments with sufficient accuracy that measurements may be taken between monuments within one-tenth of a foot or within one ten-thousandth of the distance shown on the subdivision or partition plat, whichever is greater.
Been there for years, wonder if the reference of 0.10' was taken out of context or not understood.
I see little to find fault with in reguards to ORS2.060; ( 4 ).
