I was out locating 1940-vintage concrete right-of-way markers today, cutting brush around them to be able to tie them and doing some rehab work on several that were broken. The broken markers had two rebars in them, a #4 and and #3, which I left exposed for posterity to see instead of sawing them off.
Concrete ROW Marker No. 133
(Note the square #4 bar in the photo above)
Concrete ROW Marker No. 134
The actual rebars included a square #4 bar and these two. Note the 2" spacing on the deformations of the larger bar, a #4

Oh, for the record, the flagging on the upper part of the broken marker that is supported by just two rebars ain't mine. Let's clear that up right now. :>
Kent those ends (top picture) are what I'd call shin debarkers. They are plain dangerous.
Speaking from a severe case of personal experience.
Our power supply people are very good at causing such obstacles when they cut off the stay to a power pole and leave about 3 feet of 3/4" iron road at about 45° sticking up. Oh and power poles pulled out of ground and hole left as a permanent man (leg) trap.

I bent them down below the level of the aluminum-capped monument so that their ends are actually about boot level and there is a right-of-way fence less than a foot further on. Passersby not specifically searching for the marker are unlikely. My idea may be misplaced, but I thought it would be good not to saw the rebars off at the level of the concrete stub, but to leave enough of them exposed so that some future surveyor could also examine the pattern of deformations. That particular location is one that most likely no one but a future surveyor will ever visit.
yep - point taken.
Didn't take the scale of it all in.
All this recent talk of rebars and pics of different styles has me wondering how do they make all these different styles?
The simple twisted one is easy enough to imagine.
But how about the more "fancier" ones?
Would make a good episode on a "How It's Made" show.

Rebar is deformed before it is cooled, as it comes out of an extruder.
If you have two minutes, watch this:

I figured they were extruded just like any kind of wire.
I'm more curious how they get all those different styles and patterns of ridges on them.
Kent,
Excellent work. Looking at your posts and pictures makes me rethink some of my practices and methods. I just need to come and work as your assistant for a week or so and learn some new methods.
I do have a question:
It is obvious that it takes a lot of equipment to do some of the things you do at each monument or corner search. Do you use an ATV or UTV to transport your equipment around?
Thanks for sharing.

In the case of the right-of-way markers, I just drove along the State highway, pulled my truck off the shoulder and walked over to the marker. The necessary equipment was:
- shovel,
- hack saw,
- hammer drill with 3/8" and 5/8" bits,
- loppers (for cutting vegetation away).
At one time, I carried heavy-duty bolt cutters to snip the rebars on broken markers, but the hacksaw is probably more versatile.
Once you get off the highway, most of that country is so rough that unless there's a jeep trail to drive on, access is on foot.
