Comments
Widespread avalanche cycle during storm. 7 - 12" of new snow fell on top of 3-6" of old faceted snow from Oct and Nov. Strong westerly winds transported additional load from west face of Cascade onto slopes, likely triggering all of the slides. List of visible avalanches: Bunnell's Middle Bowl and gunners right bowl. Big Bowl's 1, 2, 3, 4, 5, and 6. All slides were SS-N-D2/D3-I at or above 9800' on NE - E - SE faces with depths ranging from 7" - 15" deep and 150' - 2500' wide, and running 400' - 1800' vertical. Bed surfaces are exposing patches of ground, rock, and grass.
