...tire tracks?
[Just kidding! Wish I could post a smiley face].

BUT!!! Maybe it's the hospital meds, but I almost freaked out
when I saw what looks like...footprints...on the righthand side of the 8.0Mb color
image. I know that's a ludicrious hypothesis...But, hey! I can blame the hospital meds.
WORSE! The rocks! They're blue! And there appears to be what looks
like a couple of long narrow yellowish-white [pieces of what?] scattered among the rocks.
Are they?....

Tubular crystals that resemble pieces of bone?...Nah!

Fragments of ancient martian coral?...Nah!

Pale-yellow, narrow linear sand-crests? Yes! That's more likely.
But...could it be?....

Cheers.
