Yes, not having to deal with frost and snowplows is a luxury for which we pay in sumertime highs.

I didn't expect you to get personal. o.O

Lol. Must be a West Texas thing. That's the notation I see out there.

Out here the term "shiner" would be standard, if it did not have a number you would call it a washer, if it were numbers down you would call it a shiner with the numbers down. The material type and stamping would be noted if not normal, and if a person were of the classic tradition they would RP it out.

In all this talk about describing I would like to put forth that for me as a field guy the most helpful descriptions are ones that RP the corner, it is not called for in any reg that I know of but sure makes finding the evidence easy. It is very rare but appreciated to roll to a job with a ROS that calls out the corners from a couple topo features.

Standard practice in describing markers that fall near fence posts, particularly ferrous fence posts, should be to give an approximate distance from the center of the post, describe the post, and mention upon which side of the post the marker is situated.

The advantages are (a) to guide the shovel work and (b) to explain what may have happened if the marker that was near a post is not found in place or is found in a discrepant position. If the post has been replaced with a different post or has been removed, either of those operations may well have disturbed a marker set very near a post.

That is similar to the reason why it is good practice to note how far above or below grade the top of the marker is.

Don't you know the rules?!?!?! The last guy didn't leave you any clues, so you aren't supposed to supply any for whomever the next surveyor turns out to be. What's fair is fair. Right?

One of the most useful notes I've ever seen is found iron rebar down 3 feet. I would never have known the rebar was still there without that note.

Yes, when markers are unusually deep, noting the depth is a really important part of the description. I can think of on project where the boundary markers were described as "Concrete Monuments", but in positions that were found to fall in a plowed field. Without knowing they were set below plow depth back in the 1950's, it would have been easy to have assumed they'd been farmed out.

Here that would be a Nail and Brass Flasher. ALMOST everyone uses Mag nails now for this purpose, around here, but it is suprising how many still refer to them as "pk nails".

Careful, usable descriptions, with ALL of the information is critical, but only if you really want the next surveyor to find, use, and feel confident in your survey. If you want a piece of paper to get paid for, that is unlikely to be relied on it the future, then perhaps it helps if the following surveyor is not quite sure what they are looking at.

So, in Washington, do all surveyors call washers "flashers"? The tin discs called "shiners" in Central Texas that are used to nail down roofing felt and some insulation board are beer-can-metal-thin, probably less than 1/10 the thickness of that stamped washer.

Rain? In California? Apart from a couple of recent storms, I had all but forgotten what rain was.

One of the biggest issues I have is my field crews giving me this description: "Found 3/4" IP". And that's it. I ask them if there was a tag of some sort or how deep it was or if it was bent or damaged or anything beyond the 13 characters (including the spaces) that are punched into the data collector, but I rarely get an answer. I tell them to take a picture with the phone that is right there in their vest pocket, handy for making calls to the office, but that rarely happens either. It is an uphill battle to get these guys to understand the importance of the FULL NATURE of the monument found and one that I find infuriating.

Make them go back to the site on their own time to get ALL the information. They'll catch on...

If they don't follow directions, disciplinary action is warranted. Up to and including: "Hit the door, you're gone!"

If you can't trust them to follow instructions, you can't trust them, period.

If you can't trust them, you have no use for them.

That's what I used to have to do. I learned quickly. Of course, there are issues with labor laws.
