Lichen it or not

We took advantage of the relatively low avalanche hazard to ski a steeper north facing alpine line at Grizzly Den. Recent strong wind has hit the area hard, and while the ski quality wasnt that great up there due to the wind effect, you couldnt beat the views on a sunny day. There was still powder to be found in sheltered trees on shady slopes. The sun from today created a thin sun crust on south and west facing slopes. We also noticed some new surface hoar growing up high in isolated spots, hopefully that gets blasted away by wind before it gets buried amd becomes a new weak layer!
