In the same area as my " Tube Repair After Avalanche On Mars" video, from another perspective, are visible many "Dune Mover Machines" under the supervision of a camouflaged "Control Tower". Some "scientists" claim that these are shadows and pools of melting water. I disagree. Take a close look at the different configurations . Different machines performing assigned tasks. Some are like snow throwers and others resemble round discs. Notice the tracks each machine makes. There are also sets of three similar machines working in tandem on different dunes.

The top part of the scarp, to the left of the images, is still covered with bright (white) carbon dioxide frost which is disappearing from the polar regions as spring progresses.
