Your study of the various types of rebars is very commendable. I was wondering if you have stated in either a surveyors report, on a plat, or both, if a certain type of rebar is mentioned as far as type, style and approximate age of manufacture to further support your decisions for acceptance or rejection of monuments.
If you do cite rebar specifications would you mind posting an example?

Sure. Here's a part of the monument list off the map of that project where the hole was replaced with a new rod and cap monument.
Basically, the idea is to describe the pattern of deformations using simple words like:
- ladder,
- rope ladder,
- X
- chevron
- slant
Draw a little picture in the field book, take a rubbing if you think it would be worthwhile, and measure both the diameter of the bar and the spacing of the deformations.
The task usually boils down to:
- deciding which monuments are obviously too new to be from the original survey being retraced,
- determining which monuments share so many common characteristics as to strongly suggest that they were set in the course of the same survey,
- identifying those monuments that have the oldest or best evidence supporting the conclusion that they predate the rest, and hence are probably original as most likely also are the other monuments with common characteristics that by implication were probably set at the same time.

I like how you describe those monuments. I counted four different types that were 'old' and the junior pt no. 108.
How do you tell if a rebar that is old was one that was recently set?
Such as...
Let's just say that a surveyor happened upon a site that was in demolition and he was able to get hold of some 1930 stock rebar. He then cuts those to length and uses them in some of his 2005 surveys. What would the give aways be?

Oh, it's pretty much a matter of common sense. For example, if the corner was first marked in 1957, and the rebar is 1930's vintage, that would be a pretty good clue. :>
If the rebar had been in concrete, it would be way too fresh to have been in the ground for any length of time. The lack of change of the pattern of corrosion would, in a caliche-type soil, strongly suggest that the bar hadn't been in the ground long.
Aside from that, the fresh, sharp edges on the ends that were cut and driven (if the surveyor didn't use a drive cap), would tend to give the game away.

What if your sense, pretty much isn't common? LOL
