Sun Tunnels

Here's a satellite view of a random spot in the Utah desert.

Well...maybe not so random. There is something unusual in the middle of the photo. Here's a closer look...

Can't tell what it is? Here's a ground level view...

Still confused? It should be obvious by now. Clearly, this is four sections of enormous concrete pipe arrayed in an X-pattern...

It's the sort of thing you see every day when wandering around in the desert. That's Ron inside. I'm standing on a raised marker at the crossing of the X-pattern in the pic below.

These pipes are not light; it took some effort to get them out here and "properly aligned". So...why would someone do this? Ask Nancy Holt.
