glad all are ok. good luck with the recovery.
an initial thought i had when looking at the picts was that it seemed odd to see the crownline at the crest of the ridge. i would have expected to see it a bit lower down, where loading would presumably typically occur..... as a caveat, i don't know the terrain at all and haven't read the snow analysis in the cac report yet.... |

Given the winds on the day and the relatively moderate angle of the upper slope, it isn't surprising that the slab started right from ridgetop. In this area it was a matter of crossloading and pencil-density slabs were forming early in the outflow very near ridgetops. Things got more complex as the storm centre shifted around, but that initial foundation would have provided the weak layer...
Again, Lee, it sounds like the brain dump went fairly well. You've noted a great many important points.
Glad again that it turned into a learning experience rather than something more serious...  |

yeah rebob - i want some good to come from this. And a lot of my friends have said that if anything it shook them up from complacency.
As for me, I'm going to try to ski this weekend - groomers though. And going to try to keep the learning process going but without such direct first hand involvement |

Lee... glad you made it out fine.
I'm still new to the BC travel thing in steeper terrain and trying to understand: What exactly was the path you were taking and what was your reasoning for taking it? Did you have a reason other than familiarity that that particular path was safe? Just trying to understand the thought processes and a little bit more of the heuristics side of things.
Thanks.

The path I was taking is marked in the TGR thread as "Intended Path" - there should be a lot of photos there. It's an alternate line to contouring around and undernearth the ridgeline. It's a way to squeeze out some additional powder turns in moderate angled slopes |

My brother and I went up Whistler that day and when taking the Peak to Peak I looked over to Overlord and could see the wind howling.As well I noticed the cross loading on slopes.When did a run down to Decker Lake the usual ski tracks on Decker, but I couldn't believe when I saw two skiers doing GS turns down the finger chutes.That considerable rating is always a sketchy one.
Years ago I kicked out a slab skiing down Summit chute,luckily only went for a small ride.It's always testes out there.You just don't know when something can rip out.Glad everyone was alright |

Ok I got it. It just got a little confusing with the crossposting and all the photos everywhere. I just missed the part in the TGR thread where you did the play-by-play.
Yeah freaky stuff. It's like you made all the right decisions but were unlucky. Just stating the obvious but it just shows that nothing's foolproof out there. Thanks again.
