I dont know the detail of what happened here, but quite a few years ago I got caught out at the bottom of this route. We had been slow at the top due to poor visibility and it was late afternoon on a warm day when we got to the lower slopes, there were shallow wet snow slides going off all around us, I have never been so scared, seeing the ground move made me feel sick.
Skiers left there are a few small cliffs and steep gullies that even a modest slide could push you over.
A sad series of accidents.
