I tried just now.
I think I saw it a couple of times when I focused past it. I would need more time and almost breathe on the focus ring (move it very slightly) then look for a few seconds then repeat, etc.
But I could've just seen floaters in my eye.
getting ready for 1/4 corner saga - more data
Here is some additional info.
these are the GLO notes from 1905.
This is the 1905 Plat.
Here is the 1991 plat-
Notice the straight constant bearing of the North line of S14, with the odd chainage.

This is a pic of the cap.
This taken from the cap looking east- you can see the stump

This is at the Stump, looking toward the corner posistion.
(about were the ragtape is located.
At the cor position looking at the stump.

The stump- 20" tamarack stump 4' high. I think the more defined ax marks are probably from the era of the survey I am retracing- ' 1954-1964.

Here are 2 surveys that are from the approx timeframe of the BLM retracement.
COS 619 date 1982
the calc distance here is w/in .4' of the BLM retracement distance.
COS 772 Date 1985
I really need to see those BLM notes.
You are correct that there was a site by our Dpt of Admin. that had the the GLO notes on it. It came down in early 2010 I think. It was quirky, but you could get info out of it. We complained once saying we would like a feature that would allow us to just down load the entire township..... I guess they showed us.........o.O
A GLO or BLM plat that shows two courses (even if they have the same bearing) means that something was found there. So either the aluminum cap is a remonumentation of the earlier monument or was set from other record evidence such as a BT, or it could be based on accepting evidence from another survey perpetuating the prior record.
It is not proportioned.

I've done both, Colonial and Federal Lands. They both have drawbacks. Try retracing lines with only the adjoining owners named from the 1700's.
