I don't think it has depth. It looks like a mound. Mounds can look like craters when viewed from above.
My guess is that this is a dump or the base. When I was in college, my dad moved to Chicago. To the south of Chicago there are these "Garbage
Mountains" next to the expressway. Depending on which direction you fly into Chicago, you sometimes pass over these. They look very similar.
At those sites they plant grass and trees on the older sections. Those wouldn't grow in the desert, so they'd have to put something on top and it
looks like some kind of covering on the lower (older) sections in the OP pics.
One sure way to find out if that's what it is would be to get a night time shot. Pipes have to be stuck into the Garbage Mountains near Chicago to
release the gasses from the trash and decomp and burn it off. They look like torches placed along the mound. If we could see a night shot of the OP's
anomolies, we may be able to see the "torches."
