Stone markers from 200 years ago still vital to modern surveying work
"What's amazing is we go out there now with sub-centimeter-accuracy instruments, and we take the same measurements those guys did in 1815," Janes said. "You would be shocked at the level of accuracy those guys got."
It's amazing what those old guys did, but where I am, I'm sure not shocked at the level of accuracy:-S

Those are a good bunch of guys. I have enjoyed a few cold ones with them at a conference or two..

I think it's similar to the theory about an infinite number of monkeys sitting at an infinite number of typewriters.....eventually something intelligent is bound to happen. Same with retracing the GLO and comparing 'record v measured'...eventually there will be a number that fits what was penciled in the notes.
I hate seeing that stone in an office setting. Plant your nice shiny aluminum pipe next to it and leave it undisturbed please.

You know, I thought the same thing. I personally don't disturb existing original GLO monuments. And when setting pins near them, I call these pins accessories and allow the stone (or whatever the type of original monument) to remain as the actual corner.
But there's an ugly reality in our world around here. If you set a shiny new Bernsten post with bronze cap in concrete and call it "THE" corner....that stone somehow immediately winds up on someone's bookshelf back at their office.
There's one old Highway Dept. "employee" (I refuse to refer to him as a surveyor) that literally has a collection of almost a hundred original stones. I won't be so rude as to give his name, but his initials are Leroy E. Higginbotham, LS 84...
So much wrong about this article. Some of which has been pointed out.
How does one get appointed to the ?Commission, and is that a good thing?
Why is there a map of Central America hanging on the wall?
Seriously. The summer of 1976 I spent with a survey crew recovering section corners in Wisconsin. Sometimes the recovery was in the bottom of a 10' deep hole (where I learned to trust the backhoe operator) but we always left the monument in place. Even though I wanted one so bad. I learned a lot from that experience.
I'm not arguing what you are saying vern, but the BLM buries the stone and replaces its position with the new shiny brass cap,,,,,,,,,,,,,so everyone is basically following along, if I find a nice marked one in good condition, I will leave it and set nothing more than something metallic alongside to help find it in the snow........there are lots of brass caps stamped as R.M.'s 1' away, of course they get used as the position.:-(

Perhaps the stone was destroyed by construction or other "non-surveying" powers and they are doing their best to replace them. I wouldn't assume they pulled them out..I see the photo simply to illustrate the difference in monuments.
The commission is a QBS.
What I find amazing is (looking at that photo) and which is quite comforting, is the "mess" on his desk.
Papers, and other paraphernalia.
I cleaned My desk up this week 'cos it'd got "messy" with old cadastral surveys spread out. It looked neat, but not right somehow.
As to taking out old marks, in my youthful exuberance I was guilty of flogging an original teak corner peg and replacing same with a star bar. It is still with me.
It was on the King Island coast, littered with shipwrecks and was no doubt from such an event.
My weather beaten peg probably outlasts any iron bar out on those moist salty shores.
Only ever found one stone peg and it remains in place where it belongs.
I think we can all take a lesson from the book of [USER=321]@J. Penry[/USER].
