    Hi you found your self a dark one, makes it tricky to see what's what. The basic rule of thumb is that if you can see any direction then fan, if it's not clear that there's been a wind then blotch. Fans tend to have a characteristic shape, thin at the end where the dust vents through the ice and fatter down wind. Blotches are formed when there is no wind and the dust just settles around the vent. There's more detail here http://planetfour.org/#/about
