Noticed this avalanche with skiier tracks leading out of it. Nice hard slab. 1-2mm mature facets in the bed surface. Lots of shooting cracks on the skin up disease today. Did not trigger this, nor see it triggered, but a party of 2 leaving the chuting gallery reported that it was not there when they skinned up.
