Comments

The weak layer/bed surface was fairly subtle. Only one level of hardness difference between the weak layer and bed surface and slab. Cracking around ridgeline wind drifts. No collapsing found. The two slides were, obviously wind loaded. South side wind effected snow extended 300 to 400' below ridge line. For the new snow, that was not wind effected, no significant layering could be found.
