I like your observations and when I saw the picture I thought the same thing.
Maybe Mars is one big permafrost ball that has earth on it due to all the space matter falling on it over the decades?

If my memory is not faulty. Mars gravity is about .38-G or there abouts.
Water, I would think, would be in the atmosphere if it were that close to the surface, and they have have not found any that I know of. they think it may be in the form of ice at the poles.
I had posted that perhaps the sticky soil was from a liquid mineral of some sort, like silica.
But I figure that they will have something on that soon.

Yep..that's the guy. I just know that he's trying to distract me, so his cat can get at my kibble.
Didn't know he had made a Horror Picture, though.
Hey...just noticed we're still here! We 'd better get on-topic soon...or we'll get in trouble again.
Soo....how come Rover doesn't get in trouble for digging holes...just me.

It appears to me the trenching exposed a rock, not unlike the rock ledge lining the crater's edge (visible in the background).
It appears so bright (like talc, or magnesium silicate) because of the abrasive effect of the wheel. And it's soft enough (again, like talc) that, as the wheel climbed out of the trench, it left a trail of powder from the rock.

I know it looks nice and sunny but keep in mind it's way below freezing. -70f on average.

Looks like steering corrections, i.e., go straight, then twitch the traction differential a tad, and go straight in the corrected direction.
This sucker doesn't appear to do curves well. It doesn't appear to do curves, period. Looks like it "turns" by executing a series of straight lines, each at an incremental angle from the other. If it drove in a circle, and you looked at its tracks, you'd see a series of straight lines in the approximate shape of a circle, rather than a continuously curved line.
Why they do it that way is beyond me, but it sure looks like that's how they do it. All I've seen are straight-line tracks, with direction changes marked by an angular break in the tracks, rather than a curved section.

Looks like more of the surface material but compacted so it loses its powdery dark character.
