Those images are impressive,being able to see some sort of movement on the surface.
Though i thought Sublimation is when carbon dioxide skips the liquid state and freezes to form what is commonly referred to as dry ice (no?).So when it melts it doesn't turn into liquid but turns straight into a gas(right?)
It would be awesome if it was H
2O causing the erosion.
