Wind slabs may exist on all aspects and elevations due to variable strong winds over the past few days.
Assess your lines for wind slab before committing.
Wind slabs have formed over old, hard snow and faceted surfaces, and are unlikely to bond well
With variable winds, slabs may be found on all aspects. However, the largest and most reactive slabs are expected on north and east facing slopes
Recent reports have been limited to size 1 wind slabs.
Observations in this region are limited. Please post any photos or observations to the MIN if you head out.
Up to 30 cm of recent storm snow has been variably distributed, with wind loading and scouring could be found on any aspect. This snow overlies old wind pressed snow and facets.
A mid-February crust or facet layer may be found 20–60 cm below the surface, and appears more prominent around Haines Pass.
The late January crust is buried 50–100 cm deep below 1350 m. Surface hoar may persist above this layer on sheltered north- to east-facing aspects. This layer is more pronounced on the inland areas of White Pass.
Facets or depth hoar exist at the base of the snowpack and may be a concern in the inland side of the region where the snowpack is shallower.
