Christmas Eve with the Teddy Bear Trees

We a suspicion of triggering something near the ridge as we saw cracking while skinning up/around the ridge. The first skier triggered a wind-slab on rolling 40degree feature - just off the ridge - which quickly propagated and swept all the storm snow (15cm) 100m below. The skier was able to easily exit safely after trigger. We also heard multiple large sounding naturals from higher up.
