Avalanche Summary
Reports from Wednesday suggest small (size 1) wind slabs were reactive on a variety of aspects in the alpine and upper treeline elevations. The slabs were 10 to 20 cm thick, with some failing on a buried surface hoar layer.
Snowpack Summary
Wind and sun have created variable surface conditions, with northeast wind heavily impacting open terrain.
15 to 30 cm of snow sits above a widespread crust. Many areas have reported a weak surface hoar layer above this crust, which could be problematic in areas where wind has formed a slab above the layer.
Snowpack depths decrease rapidly below treeline.
