Great idea to use date feature on Google Earth to work out when things changed. What did the full radio wave reflector look like do you think, and what was it used for. It is not at the top of a hill, in fact in a depression. Could it have been a radar reflector for aircraft. Looking at Google Earth again, I am not sure the image now is different from the 2009 image in size and shape, but maybe could have been clad in metal. Was looking for similar images on Google image search for radio reflectors, and did not find a similar image.

I think it might have something to do with airports? There is a small plane airport about 5 miles away, but this is definitely not on the runway flighpath, never see planes overhead at this location.

Here is a good link to the photo I hope https://plus.google.com/photos/112552996997489320741/albums/5836417808740942433?authkey=CP26hfb7nNDSxQE

I can't see your link either without signing up... However from the coordinates and Google Earth and the orientation of the sides in that view, I'd be speculating that it might be a microwave passive repeater or deflector installation. No power required, but like an optical prism they bend the signal and resend it in a different direction. This is useful where direct line of sight transmissions aren't possible and power is not available. Classic use would be through a valley or around a hill or tall building where they could not use that site. That is just a guess, but depending on the size might be such. I just re read and since this is concrete, it might not be the whole thing, but might have been the Base for one in the past or near future. Anyway the idea is possible. I'll keep thinking about it and watching. Natural stone surfaces can reflect radio for sure, but I'm not sure about microwaves.

Found this object which apparently was not there a couple of years ago. In Oro Valley, AZ, close to Honeybee Canyon on State Trust Land in the middle of the desert. No other constructions nearby. It is a concrete triangle about 5 ft high, technically a triangular prism. Totally smooth on all sides and top, no holes for mounting anything. Lat 32 28.606N, Lon. 110 58.039W. Does anybody know what this might be? Here is the picture https://plus.google.com/photos/112552996997489320741/albums/5836417808740942433

Also found one of these 0.6 mile from the decommissioned Titan missile site in Catalina, AZ (now a church) Marking is 18C. It is on a hilltop on bluffs close to Big Wash.
