unusual benchmark disk stamping method

[+JL_HSTRE]

I found a benchmark which despite being older than 1969 (since it is stamped Florida SRD instead of FL DOT) is not in the NGS database.

 

Far more unusual to me was the way the BM number and elevation were stamped on the disk: as a series of tiny holes, rather than the usual form of imprinting. Has anyone seen something like that before?

I found a similar mark in Apollo Beach, FL, but it is stamped and is in the database.

I've never seen anything exactly like that, but I have seen plenty of cases of 'creative stamp usage'.

Hi Joshism,

 

Here is one we found that has the last two digits of the elevation looking a bit like the stamping your disk. This is SC0374:

Many years ago (20+) I found a USGS mark like that, we had to reset it due to road construction, it had been set in a huge surface boulder. I would assume whomever set the mark never had the dies. No photo ever taken of it.

With KY3483, all 4 disks had a portion of the date stamped in that way.

I guess they lost the 5 and 9 number stamps and had to resort to a center punch.
