There have been some amazing debris pix from Curiosity ... that NASA seems completely uncurious about. Like the thing that resembles a water pump, with pipe sticking out of it, or the helmet shaped very much like a human head/face, or the child-sized shoe.
That one puzzles the heck out of me.
Looks like a "gun barrel" sticking out of a turret to me, when I first saw it.
Just ain't nothing natural about the "pipe" section.
NASA probably sent the rover away from it as fast as possible, LOL.
