Avalanche Summary
On Saturday ski cutting produced wind slab avalanches up to size 1. Details on these avalanches are limited.
On Thursday several natural wind slab avalanches up to size 2 were observed in the region as well as natural wind slab avalanches up to size 3 in the neighboring Waterton region.
Snowpack Summary
Wind slab can be found on north and east aspects in the treeline and alpine. Some south and west aspects in the alpine are scoured. A crust exists on or near the surface on solar aspects in the alpine and down up to 30cm below 2000m on all aspects.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
Problems
Wind Slabs
Wind slab can be found in exposed treeline and alpine terrain. Sensitivity to triggering could be greater where wind slab overlies a crust.
Aspects: North, North East, East, South East, North West.
