and I take a picture of it...I just can't help myself:-) 
Pretty sparse on the information, or is it all top secret up there?
i can be blamed for this when on vacation. my bride and i try to look up good hikes when abroad, it's fun to find a triangulation station from generations back
somebody needs to paint a big pink triangle around that thing
Guilty as well on vacation:
Don't do that unless you want the overgrown Tonka toys to destroy it.
well Maybe?!..Its outside the Delta terminal at Laguardia Airport.

There are thousands of these concrete trig pillars in the UK, on mountain and hilltops, all dating from the 1930's to the 1960's when the retriangulation of Great Britain was carried out.
They're not maintained any more but a few have been retained as passive GPS stations.
Howdy,
One of the great joys of my survey career was working at remote vantage points. As GPS came to dominance, the opportunities to use them declined. Of course being atop a mesa in Wyomin at a triangulation station as a lightning storm rolls in was anxiety provoking.
While visiting NZ a few years ago, I happened upon some of their trig stations. They are still maintained and used. Some provide great views.
I took a picture that I hope can be viewed through this link. The Picasaweb page also includes other monuments I happened to find including another great vantage point on Dursey Island in Ireland.

The existence of high accuracy monuments along the roadways makes life more convenient but less interesting. I don't know whether I would be up for a 500 meter climb up a trail toting survey gear any more.
