Oddity seekers will find a bonanza when they come across a set of round relics squatting in the desert south of Casa Grande. At first glance, they look like abandoned UFOs. Closer inspection reveals they’re manmade, and they’re sort of spooky. They’re a series of domes. Some stand (or squat) alone; others are connected so they resemble a giant caterpillar. All are abandoned and have been severely vandalized, so there are no doors or windows left.
