You mean the snapshot With what looks like a broken-beak shaped support flange with the circular milled channel? Looks a bit like a chunk of shrapnel? (I assume we are looking at Mars and not some Hawaiian lava field or a Death Valley golf course?)
I liked the distance images that look like there is something standing and hovering just out of camera range, like a mirage on a hot summer road! I would think about for an explanation but its late and time to sleep!
Good night!
