sounds like the 3 people involved are ok with minor injury.

it's good that they are getting this story out. It's correct behavior.

According to the bc skier grape vine, (subject to first hand account) they were in 'steroid bowl' which is a ne face bowl gulley system in at the headwaters of early winters creek (hairpin valley).

Most people know this bowl in that the bottom gulley is the common exit to the birthday tour, after a long skiers left traverse from  pica bowl.

most people do not venture into the bowl area itself due to the large vertical rock walls, that ring the large funnel shaped  bowl, and the aspect and terrain favoring large cornice formation.

i skied this bowl once in powder a long time ago and vowed that i would never enter that bowl again.

there is no where to hide from any thing that wants to come down from above which is why even spead out skiers are at risk from multiple person involvement.

There is good reason why we named this 'steroid bowl'. It is a hazardous mountain area, with a lot of stored potential energy.

the wall and cornice fall often during the winter and can and does trigger the bowl. It's common to see large d3 avys here with large blocks. Big wet d3 and d4's can often be observed here.

 The historical path runs from the top ridge to past the valley creek bottom.

this bowl is on the avy
avoidance list.

Keep in mind that the guide trail at the head of the hair pin valley was also recently reported to have been hit from above.

One thing that i am curious about is who reported this incident to the nwac commercial advertisment service?

The skiers that were involved got the word out to friends, but nwac did not have accurate information last night, so i don't think it was the skiers themselves.


Anyway, sure glad you guys made it out without serious, life threating injury.

So i skied today with one of the guys in that avy (not local but a friend from past skis together). Three guys from out of town and one local  were involved in that slide.

They were just sending the first guy down for the descent when a massive cornice broke loose from above.

They all took a ride in a slide with the guy lowest down the slope getting hit with the most snow as the snow funneled toward the gully from the bowl.

They all stayed near the surface after going under multiple times One air bag was deployed.

The lowest down guy was buried just below the surface and was able to extricate himself.

the slide ran an estimated 1000 vert feet and contained snowmobile sized chunks.

it was reported to me that the well settled snow in the bowl did not trigger.

i'm guessing that the cornice drop cleaned snow off that wall. That's common from many past observation's of those walls.

Sounds like a large volume of
snow.

The following is just an observation and not a factor in the slide that day.

The old codggers have been codggering for years about the skin track up the hairpin valley being placed down near 'early winters creek' as opposed to  further up the run out zone, which is a common trail placement. And guess who we've been codggering.?

the reason is two fold. One, your group is further down the historical path runout zone and two, from the creek,the entirety of these ne wall-bowl-gully features can be OBSERVED as any group winds it's way up  valley (assuming proper light conditions).
