Avalanche Summary
Wind slabs were reactive to skier traffic on the weekend, generally producing small avalanches.
See here for an example. Snowpack Summary
Strong northeast winds have redistributed up to 40 cm of recent storm snow, creating 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, there is a weak layer of feathery surface hoar crystals about 50 cm deep. This weak layer is likely most prominent in sheltered and shaded areas. Also in the north, a few weak layers may still exist within the middle and lower half of the snowpack. These include another layer of surface hoar around 70 to 100 cm deep and a weak layer of sugary faceted snow around 200 cm deep.
