Looking closer now, I think it's not a shed, but a roof over a concrete floor. The west/front side is definitely open. There's some metalwork out in the open, and signs of some of the gear on the west side of the slab. Looks like they were moving something heavy, and it got bogged/punched through the cracker dust to the limestone underneath. Twice....
Of course I could be wrong, and it might just be a BBQ area for the MinRes guys....
