I stumbled across this thing a couple years ago when looking into taking a trip to eastern Oregon. Some coworkers had mentioned the sand dunes outside of the small town of Christmas Valley, and the near by "Lost Forest" sounded pretty interesting.

When I went to look it up on Google Earth, I noticed this;

No tags on Google Earth or Maps to give a clue to what it was.

Turns out it is an over-the-horizon radar system. And that is just the transmitter.
