First pic, nothing happening. I can see it now:
Workers: Oh hey, look, someone's taking pictures! (runs outside, starts the belts, and puts a little dirt on). Hardly a pile at the bottom. Worker takes a bucket and dumps some processed dirt over a gated fence (huh! what's up with that?), just to show that something's happening.
I dunno man, it all looks fishy to me. ;)
