Witness marker
Here the law states it must be clearly marked "Offset" with the distance. (I guess the plastic caps wouldn't work, and you'd need to use an aluminum cap and stamp set for that.) I have done a few of those before. If it's a "corner" I will put one on the first line and one on the second line preferably at the same distance from the corner with the appropriate stamping if possible.
I found a similar situation - same surveyor, same corner, two pins. But only about 2 inches apart! I don't know how this happens, especially when it's his plat, and both pins were flush with the surface and fairly visible.

Stephen - Glad you posted this - it was one of the first things I noticed and I thought maybe it was just me. I kept looking for some yellow leaves on the ground that it might be one of. Sure looks an uncapped yellow painted rebar to me!
PUrchased StarNet this year, didn't have it 5 years ago.
Don't have any pictures, but I found a corner with 3 alum caps, all touching each other and all from the same guy ????????????????????WWWWWWWWWWWWWWWTTTTTTTTTTTTTTFFFF??

> .... The one that comes to mind, has two adjacent properties that are described beginning from different section corners. The intent was likely that they were originally intended to be have the corner coincident, but in searching through the records this cannot be determined, therefore two points to reference two different corners.
I sure hope you merely forgot the sarcasm font........ :-/
No section corners around this survey, at least none that have been utilized in the past 100 years.
The answer could be as simple as the crew busted an angle or distance in setting the corner, but couldn't remove the first iron once it was driven sufficiently into a tree root.
Never ascribe to malice that which is adequately explained by incompetence.
I have...
those boots.
> It is interesting that some are mentioning the crew chief. Bull!!! It is ONLY the fault of the license holder. He SHOULD know from HIS research that there are multiple monuments. He SHOULD know from HIS visit to the site that there is a physical manifestation of the shameful willful ignorance that has permeated our profession.
Couldn't agree more!
I would add that if the licensee is not visiting the site (risky choice on all but the most basic of properties), then his proper training and time spent educating the crew chief should have led to the other pin being discovered prior to a new one being set. If not, then that is a fault in training by the licensee.
That mentoring we all like so much has got to include even going out in the field and teaching what seems second nature to us - look for evidence the first time you are there, the second time you are there, and before you think about setting a monument. Too many young guys are being shoved out the door with the understanding of how to operate the equipment. That does no good unless a licensee is out there with them teaching them what to look for and smart decisions based on what they are finding.
How to properly look for any and all evidence has got to be a priority in training and in my opinion is best accomplished with a licensee who understands that out in the field with the crew. With the picture posted, I can just imagine how many original corner monuments were not found or located because there was no looking beyond the coordinate in the collector.
Likely same LS but different field crews. 2nd party chief was probably lamenting the sloppy work of the first party chief as he told the chainman to set the rebar.
