Is there water between the land and the mountains, hard to tell but it kinda looks like there might be. Could be a ship?
I'm thinking maybe the top of a cell tower but there is no indication of the tower itself, can't see it at all. If it's a ground structure, being that far out it must be huge.
Edit: NM I just saw the coords, no water. Looks like a water treatment plant, so some kind of structure having to do with that, but it's pretty big. Given this looks like a desert wonder if it's some kind of drilling rig to drill for well water?
