Avalanche Location:
We rode a line down to the beaver pond (so more east aspect). Then we skinned up towards Kona and notice[d] on the steeper slopes some shooting cracks on the switchbacks. On our second run I ended up catching some air off a pillow and when I landed on the convex slope below it propagated. Luckily I was able to ride immediately off the soft slab and get above a tree. We then took the more mellow slope down Kona ridge to the canyon road and walked back to the resort.
