Thats what we do. Usually One on a chainsaw. (Stihl pro) A couple of hookers. Looks like a trail when we are done. I think we cut it more for the biologists and dirt sniffers that come through after us than it is for us. So they dont get lost in the woods.

We try to clear what we can but at the same time one must respect property, especially private property. The c. 1976 case of IMEC v. Stevenson immediately comes to mind.
The only superior evidence is that which you haven't yet found.
I thought we were talking about traverse lines. Presumably, if one is on another's property, then there is either a right of entry or permission has been asked for and received.
We were. In this case it's on our own land. That said though, am impressed that anyone could make such a statement such as "IMEC v. Stevenson immediately come to mind". Ya, that's what I was about to say.:-D

OK, my bad. I did not realize it was on your own land. As a DOT surveyor we have statutory right of entry, so my thinking was probably tainted due to that. Nonetheless, the red on my face isn't sunburn.

I usually use a tack or mag nail with a wad of flagging. Sort of a vertical control point. Can't set up on it but you can use it for a back sight or resection in combination with another. I was following an old survey looking for one of these and found it, 15' up a utility pole! Thought to myself how the heck did he reach to set that target up so high? Apparently, there had been 10' of snow at the time. Had to go back and get a ladder to reach the darn thing for a shot.
When possible, I like to set a few of those roofing tacks with the plastic disc adequate distances from my instrument point. I frequently use telephone poles. This allows me to:
1) If running a two man crew and need a quick setup, I can get a backsight with the rod. I can then immediately shoot in my tack reflectorless in the pole, store it, and by the time the rod guy has made his way to the sideshot, I have already reset the backsight to 000-00-00 on the tack. When done, I can just check with the tack instead of making him walk 300' out, then 300' back.
2) Allows a resection if I can't find my traverse point. I can setup anywhere near where I think I should be, create a temporary point, and figure out what my relation is to the traverse point I'm looking for.
3) As you pointed out, it serves as a good check for your vertical measurements.
In using freshly cut trunks or "stobs" of trees large or small I was always concerned that there would be movement as the trunk adjusted to the loss of the (perhaps leaning) tree above it. I can't recall if I ever observed that, but for low accuracy woods surveys a little slop is tolerable anyway.
Did someone mention traversing to the top of a 4' lath, then once you move up and set up over it you set a spike nail under it using the optical plummet (lath has to have some lean, and you need a mini prism not a range pole prism for the tie)?
I miss long woods traverses too.
