To me, Friend,
They look very much like old, discontinued central pivot sprinkling systems.
However, the concentric circles are too many and too close together for that, imho.
Yet, their size and placement near each other also looks like that.
Quite puzzling. Please U2U me if you ever get a definitive answer.
Blessings,
That's what I was thinking.....
But they're spirals, not concentric circles.
Also, I can't see them setting up sprinkler systems in those locations.
I've been doing some reading on desert / watercourse reclamation (riveting stuff). I think Chadwickus might be right, but I can't find an exact match to the spirals.
Then again, Wycliffe's "only" 400k's from there, so it could be a UFO landing ground
