 Comments: We observed many size 2 natural avalanches that failed in the Jan11/12 storm snow. We observed one size 3 natural avalanche that failed on the Thanksgiving "turkey sandwhich" layer (the s-word is overused these days). The starting zone was east-facing, 8600', 36 degrees. It was approximately 75 meters wide and the crown was over a meter in some areas. It ran about 600', nearly full path. The pics are of this slide. Of note, the east side of Copper was nuked by winds sometime between Dec 10 and 15. The areas we saw today that we remembered being nuked by wind and had slides in the storm snow did not step down to the Thanksgiving layer. The area where the size 3 was observed tends to be more protected
