Observations

While skinning up Snow shed face, skiers above us triggered a D1.5 wet loose avalanche. We were near where the slide ended, and chose to turn around. Lots of fairly large tree bombs were also dropping in the woods next to the face. We also observed other signs of wet loose activity on the same aspect + slope.
