In October we bushwhacked over  to the structure we’d seen from the trail in September. We were able to confirmed that it is certainly a human made structure. Who made it and when is still an open question. It was built in an area that has more grasses than most of the desert nearby. my guess is that it is a shepherd’s corral dating from 1900 +/- 30 years. But I am speculating. I shared the photos and the location with the Phoenix City Archeologist and I’m hoping to get her much more informed opinion in the next few months.
