Moderate
Avalanche Summary
Storm slabs were reactive earlier in the week, with numerous natural, human- and remote-triggered avalanches up to size 2. On Wednesday, avalanche activity became more specific to wind-loaded features, with several naturals up to size 2.5 on north to east aspects in the alpine and upper treeline elevations.
Snowpack Summary
30-50 cm of recent snow sits over a layer of facets formed during the early January cold snap. At upper elevations, the recent snow has seen some redistribution by wind. At lower elevations, a thin crust or moist snow may be found at the surface.
Old layers of surface hoar and crusts in the mid snowpack appear to be healing. The mid and lower snowpack is generally strong and well bonded.

Terrain and Travel Advice
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- Caution around convexities or sharp changes in terrain.
Problems
Wind Slabs
Recent snow has been most reactive in wind-loaded terrain features such as below ridge crests and roll-overs.
