This week's cold temperatures coupled with the shortest daylight hours of the year can make any sort of incident (even broken equipment) an epic. If you decide to brave the cold temps make sure you are prepared for the conditions; bring lots of warm layers and a headlamp.
Summary

Avalanche Summary
No avalanches have been reported in this area recently. If you venture into the backcountry, please submit a MIN report, as it helps to strengthen our data gathering.
Snowpack Summary
Snowpack depths at upper elevations are around 80-100 cm.
Surface: 5 -10 cm of new snow buries previously hard wind-pressed surfaces in the alpine and faceting surfaces in sheltered areas.
Upper-pack: 30 cm of light snow continues to facet with cold temperatures. In exposed areas, you will find a series of old wind slabs and crusts on steep solar slopes.
Mid/lower-pack: Buried 50-70 cm deep, a layer of surface hoar, crust, and faceted crystals. Observations are limited in this region but this layer has produced numerous large avalanches in the neighboring regions. Below this layer, the snowpack is generally weak and faceted.

Terrain and Travel Advice
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Use ridges or ribs to avoid areas of wind loaded snow.
Problems
Wind Slabs
Recent winds have pressed surfaces and scoured the alpine. Watch for pockets of isolated windslab that are reactive to human triggering. Seek out wind-sheltered terrain where you can avoid wind slabs and find great riding.
