That's certainly a good one, as though looking kind of "old railway
sleeper" artificial. (? apparently Mars once had trees to make rail
ties?)

Seems they ran directly over the top of it, so it's not such a large
rail sleeper/tie as you'd think.

However, small Mars folks shouldn't have needed much bigger than
quarter-scale.

btw, is it polite enough policy to ask, how old are the frames within
this composite image?
