As of so many times before qmantoo, you have sharp vision for suspicious items.
These photos show without a doubt-3D building, viewpoint ca. 90-120 feet above the subject matter.
It is strange what the Rovers are versatile in this regard here on earth is not easy to take pictures from this angle. Yellow arrows highlight the details supporting statement (3D form)
This is an interesting one as I suspect they might be taking down a structure.
These 4 photos are taken 8 minutes apart. The first two, then the second two.
The two above (left and right) are just to show that there is a small rock present.
now for the ones taken 8 minutes later
the two above (left and right) show that the pale things that look like pipes or a bridge are not artifacts. The small rock does not appear to be there - unless you can point it out for me. Again I might be making assumptions...
