Be on the lookout for isolated pockets of wind slab in the alpine.
The shallow snowpack remains the primary travel hazard with lots of rocks and trees at lower elevations. Allow adequate time for egress and emergencies during these short days.
Pockets of wind slab exist in exposed alpine terrain. These pockets have not been reactive but it may be possible to trigger an avalanche in steep terrain where the snowpack is shallow.
There has not been any recent natural or human triggered avalanche activity reported in the last few days.
Thanks for the MIN reports!
The surface consists of a thin suncrust on steep solar aspects or minor wind effect in exposed alpine areas. Good powder can still be found in protected areas.
A rain crust is down 40-60cm in the snowpack, and exists up to approximately 2200m. The height of snow at treeline is ~120cm, and down at Rogers Pass (1300m) is 45cm.
