More detailed information about the avalanche: 

My two partners and I skinned up to the top of the Skook Chutes and dropped into one of them around 12:30 pm.   We witnessed snow being blown up and out of the chute before dropping in, but it was likely that the slope was being cross-loaded as well.  The first skier dropped in and triggered a slide that was about 8-12" deep on top of the rain crust from Friday night.  He skied out of the moving snow and let it flush down the path; the three of us then skied mostly on the bed surface for the entirety of the chute.  This slide seemed to have a considerable amount of energy and propogated out on both the right and left sides of the skier.
