General Comments

Remotely triggered a nice soft slab from around 50' away and on a ridge-top. I can't say we were surprised after triggering numerous shooting cracks, some from a distance.... Sensitive conditions, and the avalanche ran further and faster than I might have expected...

The entrance of Hunter's Cave shows the productive snowfalls from November and December in an overhanging stack of obvious layers........
