I been working on my Corner Record Documentation. I finally decided to keep it to about two main pages and then add attachments to the pdf file for the supporting doc's including a few pictures. It's been checked and meets the requirements for the work I'm doing. I think a surveyor will be able to get this out of the statewide GIS before to long (click on the corner).
It does make a large file with the pictures (about 2.5 Mb).
I've got a bunch of these to do but after I've got it worked out it shouldn't take that much office time to put each one together.
Here is a link to my first file:
With the pdf file open the (paperclip) to the left will give access to the attachments.
> I originally found this corner in 1997. This is an existent original corner established by GLO Deputy Surveyor A.D Ferron in 1872. I measured the stone to be 18x16x10 inches and it is marked with 6 notches on each of the 4 corners. I temporarily tied it out to two 3/8 x 8 inch spikes. I dug a hole deep enough to bury two feet of the 30 inch long Sanpete County section monument. Directly under the new marker I set a clear plastic enclosed DEEP-1 ceramic magnet. I back filled the base of the new marker with two bags of dry mix concrete and then rebuilt the stone cairn around the new marker about 4 feet diameter and about 8 inches above natural ground. The original marked stone is buried in the base of the cairn on the NEE side of the new marker. I then set up a GPS antenna on a tripod and collected data overnight. The OPUS output from the session is part of this report as are my GPS bservation notes.
Suggestion:
>I had previously found this monument in place in 1997. I take this to be the original corner established by US Deputy Surveyor A.D Ferron in 1872 during his survey of _____ as described in his field notes recorded _________. Ferron reported that he had set a _________. I measure what I take to be the same stone as 18x16x10 inches. The stone is marked with 6 notches on each of the 4 corners.
>I temporarily referenced its position with two 3/8 x 8 inch spikes that I had just bought at the hardware store and that were not very rusty - although a bit greasy - removed the stone, and dug a hole deep enough to bury two feet of the 30 inch long Sanpete County section monument. Directly under that new marker I deposited a clear plastic enclosed DEEP-1 ceramic magnet. I placed two bags of dry mix cement and aggregate around the new marker in the hope that it might eventually harden into concrete and then rebuilt a flat ring of stones around the new marker about 4 feet diameter and only about 8 inches above natural ground. The original marked stone is buried under this ring on the NEE side of the new marker.
>I occupied the new marker with a survey-grade dual frequency GPS receiver and antenna and logged 12 hrs. of L1/L2 observations on it in a session several months before the concrete had set. I've attached the output listing returned by the National Geodetic Survey's Online Positioning User Service (OPUS) from that session before the concrete had set.
We've had some nice rain this week. That concrete will be hydrated shortly. It won't be 4000 psi but many times more solid than the dirt I excavated out of the hole. There is no requirement that I place concrete to set these marks. Most guys around here leave them sticking out of the ground about a foot and a half in loose dirt and some rocks piled up. Digging that extra foot or so takes a long time.
Granted it would be better to test the temp, slump and air and cast some break cylinders but it's not in my contract.
