Arizona is pretty well-known for being home to ruins and ghost towns. Review any “Things to do in Arizona” list and you will find plenty of recommendations for abandoned places to roam and explore. But what about those places that are off limits, the ones with the large “No Trespassing” signs spread out every fifty feet down a barbed wire fence? Today, we’re going to look at one such place: the domes at Casa Grande.
A quick search for the place on Google maps elicits a view of what appears to be a broken caterpillar resting in pieces along a series of small washes. A round head sits next to pieces of a thorax and abdomen strewn behind it, as well as ghosted outlines for where other parts could have or, in this case, should have sat.
As with any strange, long abandoned area, assumptions and rumors abound for possible origins of the structures. Everyone has their own story, ranging from alleged hauntings to the perfect site for cult happenings to smuggling and trafficking activity. In truth, though, the domes have a much more humble story.
