What is this?

[vash]

Freaky! we never use these anymore. But I have one just in case. Heck. I think I have four.

It looks like a dikfer to me.

[vash]

Haha. Great joke.

This is all I have left of the survey years, except sore knees. Can't even find a plumb bob.

Dumb question, but why can't you just turn your head?
Hiding from German troops with mustard gas in those orthogonal trenches?

Want one?

[BeyGon]

want one what, that's a picture of a T-2 in Alaska. I was wrapping angles and shooting distances for miles up there. Things got a lot easier with GPS. Everyting had to have earth's curvature calced in with that and the HP EDM.
A helicopter would drop me off there, once we scared a bear and he left a steamy pile right by the control point.

you can turn your head but this thing can make you look left and right at the same time... that would be painful if you tried it by just turning your head... (dual prism, one will give an image of the left side, the other of the right side)

Very useful for setting out lines and 90 degree angles.
They are kinda obsolete now but still have there uses here and there.

Looks like you got to visit some pretty cool places at least. You might have been the only person to have ever been at some of them.

Sometimes I would think that but then come across a falling down shack next to a small mine in the middle of nowhere. I think every square foot of land in South East Alaska has been walked on.
As for set up points like these, someone had hiked up to them in the 30s and triangulated them. In Alaska I always flew in by helicopter. Sometimes the thing just hovered and I off loaded, same with leaving, it came in, hovered against the side of the cliff and I on loaded.

Is it heavy? Then it's expensive, so don't touch it!
