Wouldn't it sublimate at Martian pressure and tempuratures? Don't know just asking.

I'm just guessing, too. But if the frozen water vapor was physically bound into the soil (e.g., like clay), I would imagine the crust could take on the plastic consistency suggested by the drag-marks of the retracting airbags.

Yes.
