    does anyone have a theory as to why the ice is so clean,does it defrost and refreeze?

    We think, very early in spring CO2 ice goes via annealing transformation and turns into slab ice - very transparent form of ice (if you ever saw images of frozen Baykal lake where you can see several meters down - something like that). It takes only a little heat to do this and the result is that one can see the surface below. But I think, the top of this slab is still "peppered" by dust, so I would not call it really clean-clean.
