Isolated pockets of wind slabs may linger in steep terrain in the alpine.
Wind slabs may linger on shaded aspects in steep, alpine terrain. Assess for slabs prior to entering high-consequence terrain.
Riders triggered small loose and wind slab avalanches on Friday in steep northerly alpine terrain. Looking forward, it may remain possible for humans to trigger similar avalanches in steep features.
Northerly alpine slopes hold 10 to 20 cm of settled storm snow that overlies a hard melt-freeze crust. Isolated wind slabs may linger in steep northerly alpine terrain. All other aspects and everywhere below treeline have a hard surface crust.
The remainder of the upper snowpack is a mix of hard snow and crusts. The lower snowpack contains old weak layers that are currently dormant.
