That is the most profound concept I've ever heard.

No...the hash marks I am refering to appear to be 6-8ft apart.

My take is not permafrost, but compacted fines. When run over talcum powder clumps and shines.

Sure looks to me like Mars isn't very big. That horizon is really curved.

Great, now the eco-geeks will start crying about ruining the ecology of this now spoiled wilderness.

OK, so it's winter here in Wisconsin, lots of blowing snow . .and wherever you see a windbreak, you see snow collecting on the other side (farmers fence, snowbank, etc.). Wouldn't the small crater that Opportunity is in have the same thing ? Wouldn't the lighter windblown particle decelerate over the crater and collect in patterns that look like a snow drift ?
Your observation about the white stuff being partially picked up by the right wheel and carried out is, I think, right on. It would appear that we have a change in the color of the sand (from the "red" windblown stuff to the native white layer under it) that would be an underlying layer of thicker, more tightly compacted (think snowpack) layer.
Interestingly, MSG and ME have snapped some amazing activity of blowing sand on the planet, some pictures I've seen make it look like a niagra falls of sand instead of water. The weather and the sand may yet prove to be the most amazing part of this exploration.

OK, what's the white stuff in the tracks? Clearly, they've scraped off some of the chocolate surface and exposed the nougat:

Why the trench? Did the Rover make it? Yes, they had it sit in place and spin one of its wheels.
To: BenLurkin
I hadn't noticed.
I was too awe struck by your wisdom.

I caught a tidbit on radio something about the largest diamond in history having been found.
Maybe it was found on Mars.:-)

Riiiight, I remember working on a film lot once, they had a girl who came around regularly, her name was "The Snow Queen".
They have snow on mars?

Looks like it may have run over a nest of the endangered Snowy Plover...

"It cost an awful lot of our money so this toy can dig a hole." Think of the millions we could have saved by just sending a DitchWitch trencher up there!

Re:
Look at the tracks. Every few feet there is a hashmark. What are those? The rover wheels have no "axle" in the classic sense of an automobile.
Each of the rover wheels are attached to their "drive train" on the tread side, inside the wheel. Thus, their fasteners leave marks in the sand as the rover wheel turns.
Note that in the above picture, the guy is holding the wheel up in his left hand, over his left shoulder . . it's as big as a human head.
