Drove past this one. Had to stop to get a Picture.
NICE!!!
Did you check to see if it was level?
So, looks lika leica!
Kinda sorta reminds me of about ten years ago when I had to sit a laser tribrach over a finish nail which was set in the top of a 6X6 fence post.
Sometimes, you just have to improvise...
Looks like it's taking a leak!
It's creative, I'll give them that.
Should be a reliable 30 minute static session!!
Been there, done that.
Drive a springhead nail (roofing nail) in post and that fits neatly in and locks under the top retaining metal strip of the bottom leaf.
It can make a rock solid setup.
Wonder how well the GPS performed under the gums?

Sit in on the fence post if it's that big?
Yep. I took sideshots to it from two different setups IIRC. Also, that word should be *SET*, not 'sit', a laser tribrach... it was just the tribrach and glass, no tripod needed.
Probably not too unusual, but this is what yesterday's session needed, and a first for me.
The disk is down there beside the Gammon reel. Notice the 1910 date cast into the concrete, I suppose when the railroad was put in. The tracks have been gone for decades now and in some areas the route is hardly discernible.

Never can anticipate when a difficult setup will present itself.
I have taken flaggin and strapped a lath to extend a tripod leg and make a setup similar to that in the past.

The date on the bridge is more likely the date the bridge was constructed. Same with date nails in the crossties. The Texas and Pacific in my home area has a lot of pretty concrete culverts with headwalls dated 1932 when they did a lot of track improvements although the line originally was constructed around 1881/1882.

Can anyone explain exactly what is going on here?
Is it a scan?
i have become flummoxed looking at the picture.
photo control probably
Scanning interstitial space of a hospital.
Two odd setups. One being on the vertical face of a boulder (bearing rock). The second being a mineral survey stone corner in the lower right of the photo that I had some difficulty getting to and esp. holding the rod plumb without tumbling down the hill.
Had to wedge a small rock in the crack for one tripod leg.
The bearing rock (upper left) was even more precarious to get a shot on.
