A UFO believer saw this in the Arizona desert on Google Earth, and proposes that it might be a crashed UFO. The tiny white circle on the upper right of the object was added by the computer program used to view the photo. Here are the results of my investigation.
The object is at the upper left. At the lower right, the white truck and a black truck seem to be at a tent camp on the current Google Earth Image.
If one follows the road out toward civilization, one comes to what appears to be a ranch gate and houses and corrals. Also, there is this round object, apparently a water tank about 20 feet tall, going by the shadow, and of the same size and appearance of the object. Have we solved the mystery?
