An interesting video I found regarding a Mars mining dig with robots? Below is the description that explaines the video:
Ancient Mars mining equipment frozen in a picture of Cape St. Mary's area of the Victoria Crater rim.
It also appears smaller beings may be under and beside boulders. Quite dead, frozen, even petrified, yet protected some what from the sandstorms in the crater.
A white creature (center) appears bug shaped, a dog shaped outline on a rock could be a reptilian, one other on a rock looks more like a frozen Grey alien slave biodroid that may have been cloned for labor?
The mining magnetic claw bulldozer(top right), the (bottom left) auger drill/pipe joint, plus the one big Mech Robot suit (center right) stand out the best. My pencil sketches of these items are also in this slide show.
