I assume you're referring to Fig 31. (I was referring to Fig 32) "Spherical" clumps of blue dust would crush just the same. Mars is reeeeally cold a lot of the time and has a bit less gravity. Dust can clump. Again, not a geologist. What's important to me is that they're presenting crossing tracks as evidence of before/after, when it's not. They don't have two images of the same area separated by X days, they have one image of two tracks separated by X days, and are interpreting the crest-clumping as "new". This is a somewhat disingenuous way to present, if I'm reading it right. I'm into sending a robot to grab some, don't get me wrong, but I'm also not privy to all the details to make an intelligent prioritization of the robots' time.
