Just look at the tree (it is the same one from different directions, North, West and South) and guess the wind direction.
Yes, it is from the South, all the moisture froze on the trees, building up long ice and snow needles. Now you can see that the prevailing winds are coming from south or southeast and that is actually the direction where we are getting decent precipitation from.
Have a close look at these snow needles:
I just came back from "Veslefjell Rundt", which has not been cut this season, so it took me awhile to fight my way around in the "sour cream condition". Muen behind me.
