Avalanche: Alexander Basin

First skier triggered 1st slide unintentionally. Slide broke above skier mid-slope and washed around him due to very soft nature of slab. First skier skied to bottom of the path and waited in a safe spot. Second skier skied down slope, uncertain if first skier had triggered a slide (visibility was nil) but was aware that 1st skier was in a safe spot. Second skier got to about mid-slope and stopped, noticing a crown. While stopping at the crown a secondary slide was initiated above the 1st slide. Again very soft slab that washed around second skier. Remaining skiers stopped above crown and confirmed that the weak layer was facets below a rime crust. Debris deep enough to bury a person- size 2. Of note- although there was intense wind loading at the ridge, there was no wind loading at present or previous mid-slope where slide was triggered.
