General Comments

Upper skiers left side of crown, triggered remotely from along the ridge line. Very sensitive, and propagated further than I expected. We only had one small collapse along the ridge before this released.

General Comments 2

Slide propegated about 300' to the right. Arrows are right flank. With the shallow pack, even a short ride would have taken a person across rocks or into trees.

General Comments 3

Heavily wind loaded part of the crown. The upper part of slab was 1 finger to pencil hardness. Slab thickness rapidly decreased down slope.

General Comments 4

The slide released just below the rime crust that was deposited Sunday, Nov 14.
