this was a situation where they did everything right.
friggin' butt-sliders ... they ruin the trail for everyone
glad they're alright ... lucky !
I might not go that far, as they did not recognize the isolated pocket of avy instability until it was too late. Lucky indeed.
Nice analysis by Jeff Lane and fellow USFS snow rangers.
I've been trying to decide if I'm agreeing with Giggy or Dr Daisypodidae. Maybe other avy-savvy folks can offer input on my thoughts.
First, I don't think you can just rule out travelling up any gully with pockets of new surface on a springtime, low avalanche rating day -- but maybe I'm wrong in this. The climbers probably could have seen the new snow before they reached it, but not necessarily have known how deep it was or how well bonded.
At this point would the "no mistakes" course of action be: turn around? move off to the side away from new surface (what if you can't easily avoid it)? Unless there was a protected spot, I don't know how you're going to assess bonding. And if I reached the base of the slab and found what they found, I'd have done what they started doing... getting out of the way.
Am I missing some other consideration in thinking about this?
And, I agree that there was no way that snow rangers on the floor of the ravine could have predicted a small area of unbonded slab in one gully, hence their "low" avy forecast.
