Comments: 

Several slides intentionally triggered today using ski cuts. All slides were on upper elevation northerly facing slopes that harbored weak faceted snow. Depth varied, with maximum depth around 2'. Slabs were both hard and soft.  One slide sympathetically triggered adjacent slopes. These slides were entraining a decent amount of snow, and were large enough to injure or bury a person. Very dangerous conditions exist, particularly upper elevation northerly facing slopes.Photos below show two of the slides and one of the faceted snow in the weak layer that failed.
