Avalanche Summary
Wind slabs and storm slabs were reactive to skier traffic on Saturday, generally producing small avalanches.
See here for an example.Snowpack Summary
Strong north to east wind redistributed the 40 cm of recent storm snow, which has created wind slabs in lee and cross-loaded terrain features. This snow overlies wind-affected surfaces in the high alpine and a thick melt-freeze crust at and below treeline.In the south of the region, the remainder of the snowpack is well-settled.Around Bear Pass and in the north of the region, you may find two or three weak layers of feathery surface hoar crystals between 50 and 100 cm deep. These weak layers are likely most prominent in sheltered and shaded terrain. Also in the north of the region, the base of the snowpack may be composed of weak and sugary faceted snow.
