Avalanche Summary
No recent avalanches have been reported.
Snowpack Summary
Alpine and upper treeline terrain is heavily wind affected, while a hard crust is found below 1800 m. A solid mid-pack sits above some decomposing crust and facet layers near the bottom of the snowpack (100-150 cm deep). Avalanche activity on these layers has been sporadic, mostly triggered by large loads such as wind slab avalanches and cornice falls. These layers should be unreactive under the current conditions, but steep rocky slopes should still be carefully assessed and approached with caution.
Terrain and Travel
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
Problems
Wind Slabs
Although unlikely to trigger, hard wind slabs in the alpine have the potential to propagate widely.
Aspects: North, North East, East, South East, North West.
