FACETS (human factors checklist by Ian McCammon) and ALP TRUTh (
avalanche risk checklist by Ian McCammon)
In the interests of helping us learn, will each of you (Lee, Richard, Phil) answer the FACETS & ALP TRUTh checklist questions with Yes or No (if appropriate feel free to add additional text to your Yes or No answers)? Also, what would you do differently?
a) FACETS (human factors checklist by Ian McCammon)
Was your decision making influenced by:
F: Familiarity (Yes or No)
Yes
A: Acceptance (Yes or No)
No
C: Commitment/Consistency (Yes or No)
No, I think that is quite apparent from my write up
E: Expert halo (Yes or No)
I still don't get the question here. Would I have second thoughts if I was able to ski that run, had I had a second ski, but was worried what a dominant partner would think. If that's what your getting at then absolutely not.
T: Tracks/Scarcity (Yes or No)
No, we had basically an entire north american mountain to ourselves (i would imagine fissile is prob around 1500 acres of skiing), so was i worried that i wasn't going to get fresh tracks no.
S: Social Facilitation (Yes or No)[COLOR="Red"Again, don't really understand the question here. We picked a safe route to the summit, backed off a few runs, and skied one run before the slide safely. If any of us would have had any doubts, I don't think we are the type of group to hold back those thoughs.[/COLOR]
b) ALP TRUTh (
avalanche risk checklist by Ian McCammon)
Did you observe:
A: Avalanches (Yes or No)
I don't get it again. Did I observe avalanches on the way. No, if we did we probably wouldn't have skied. Did we see big slides the day before, no. That probably would have influenced our decision making. Did I observe my buddies in an avalanche, yes, but that is after the fact so thats like saying hindsight is 20.20.
L: Loading (Yes or No)
We knew areas were loaded as they typically are in the coasts. In my experience that has been manageable. I wouldn't say a Yes answer to this would stop me from skiing any runs differently.
P: Path (Yes or No)
Everything in Whistler is above alpine with cornices and big bowls. So like it or not we are always in start paths or run outs. Would this change my decision making, absolutely not.
T: Terrain Trap (Yes or No)
Yes, there are is a terrain trap were the slide happened. However as I mentioned earlier, I would say over 50% of the terrain we ski in bounds at W/B has terrain traps. So unless I consciously decide not to ski any of these in bounds, then it's going to be really difficult for me to stop skiing them out of bounds as well.
R: Rating (Yes or No)
I can't say with certainty but I believe it was moderate that day.
U: Unstable Snow (Yes or No)
Had we noticed any until that slide, no. We had sluff on our first run, but we were expecting that.
Th: Thaw Instability (Yes or No)
No.
Conclusion. I would say based on this survey we would be at a a 3 or 4 rating. .
c) What would you do differently?
I've thought about this one quite a bit. I think I would bring a Sat Phone. I think I would bring some pain killers in case something like this happened again. But ultimately no I wouldn't change anything.
Also any plans for additional
avalanche education (Canadian
Avalanche Skills Training (AST) Level 1, Canadian AST Level 2, reread specific books or articles, regularly read magazines like The
Avalanche Review and/or
Avalanche.ca Journal, review the online
avalanche course from the Canadian
Avalanche Association
www.avalanche.ca/cac/training/overview, etc.);
I would like to do a Level 1 and I would like to take a wilderness survival course. When I will be able to take these with work is beyond me.
additional medical training (Basic Wilderness First Aid, Advanced Wilderness First Aid, Wilderness First Responder, Wilderness EMT, Wilderness Practitioner, Outdoor Emergency Care Technician, etc.);
and/or additional equipment (satellite phone, VHF radio, helmet, avalung,
avalanche air bag, specific medical / other survival items, etc.)?

F: Familiarity
“Don’t worry. I was here yesterday.” People take more risks in terrain they’re familiar with. Don’t let familiarity fool you. Conditions change minute-to-minute, so treat all terrain like it’s the first time you’ve seen it. An
avalanche does not care that you are a local.
A: Acceptance
Consciously or unconsciously, we try to win over approval from our friends and peers. Pushing on because you don’t want to sound like a worrywart, not speaking up because you don’t want to go against the grain, even though things don’t feel right—these are examples of Acceptance.
C: Commitment/Consistency
“I’m gonna ski that line/reach the summit even if it kills me.” It might. When we have an overwhelming commitment to a goal or belief, we tend to block out our better judgment and focus on the things that will help us achieve our goal. We mistakenly simplify our decisions by only choosing to believe only what supports with our commitment and ignoring new information that is inconsistent. No
avalanche cares about your preferences.
E: Expert halo
The person who takes the lead might not always know best. Sometimes the expert is just the person who knows the route or has the strongest personality. “Oh, he’s been here before and has a lot more experience than I do. It’s probably fine.” Be mindful of these thoughts, and speak up if you’re having them. Chances are someone else in the group is having them, too. As Andre Roch said "The
avalanche does not know that you are an expert".
T: Tracks/Scarcity
Everyone loves fresh tracks. When there are multiple parties out to poach a limited number of lines, we tend to take more risks. We want that snow for ourselves. Pay attention to that desire, but don’t give in to it when things are sketchy. Also: existing tracks give a false sense of security. Just because someone skied it doesn’t mean it’s safe.
S: Social Facilitation
This is the herding instinct or groupthink. We like to go with the flow when we’re with groups. It’s easier to step into a dicey traverse when three others have gone before you. Speaking up is one of the hardest things to do. Remember to always assess the situation as if you were traveling alone—even when you’re in a group of “experts.” Selectively be the devil's advocate to avoid groupthink and to stimulate discussion.
ALP TRUTh (
avalanche risk checklist by Ian McCammon). An alternate mnemonic closer to the order likely to be encountered on a tour is Crazy Ava’s Unstable Patter Traps Local Thugs (Considerable, Avalanches, Unstable snow, Path, Traps, Loading, Thaw). Obvious Clues Method p.8-9
http://www.avalanche.org/~aaap/archi...25_2_LoRes.pdf http://backcountrybeacon.com/2010/02...th-and-facets/
A: Avalanches
Are there signs of
avalanche activity in the area within the last 48 hours?
L: Loading
Was there loading by snow, wind or rain in the area within the last 48 hours?
P: Path
Are you in an
avalanche path or starting zone?
T: Terrain Trap
Are there gullies, trees or cliffs that would increase the consequences of being caught?
R: Rating
Is the danger rating considerable or higher?
U: Unstable Snow
Are there signs of unstable snow, such as whumpfing, cracking or hollow sounds?
Th: Thaw Instability
Has there been recent significant melting of the snow surface by sun, rain or warm air?
Total yes answers. 0-2 normal caution, 3-4 extra caution, 5-7 not recommended.
