Sending this message was important to us. We considered ourselves to be a powerful culture.
This place is not a place of honor...no highly esteemed deed is commemorated here...nothing valued is here.
What is here is dangerous and repulsive to us. This message is a warning about danger.
The danger is in a particular location...it increases toward a center...the center of danger is here...of a particular size and shape, and below us.
The danger is still present, in your time, as it was in ours.
The danger is to the body, and it can kill.
The form of the danger is an emanation of energy.
The danger is unleashed only if you substantially disturb this place physically. This place is best shunned and left uninhabited.
I love the WIPP proposals. I grew up with this - WIPP shipments go right past a place my buddy used to live and lots of the WIPP waste came from my town. The problem with all of them is they look metal as fuck. And there's no monument you can build that will repel people - realistically speaking, Stonehenge might as well be the WIPP site circa 2200 BC. Know what they shoulda done? Build like five of them in the middle of the Serengeti and see what the Tuareg do with them. 'cuz you know what? The VLA is less than a hundred miles away and the hunters stay the fuck away because it spooks 'em. 
Some of the more cosmopolitan Tuareg may take them out with rock and roll and motorcycles, or go play a show in the spike town. I agree they are MAF. One thing that came to mind when I was reading this article was the Hartford in Washington State. It's a major risk to wildlife having it hanging right along the Columbia River. They clearly need to learn a thing or two about nuclear semiotics too, based on a quick google image search: 
I grew up near the Savannah River Site. We had them too I think every teenager in the surrounding counties had a stolen one on his bedroom wall.
