Avalanche Summary
No significant avalanches have been reported in the past few days. If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.
Snowpack Summary
5 to 15 cm of new snow has fallen on wind-pressed surfaces in the alpine and crust on solar aspects around treeline. Soft older snow may be found in shady, wind-sheltered areas. Weaknesses in the mid and lower snowpack are unlikely to produce avalanches under the current conditions. A weak layer of surface hoar/crust/facets buried in early January is now over 1 m deep in most areas, and has not produced avalanche activity for several weeks. The lower snowpack consists of basal facets, particularly in thin snowpack areas.

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.
- Pay attention to isolated alpine features as well as cross-loaded features at treeline.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Problems
Wind Slabs
With only 5 to 15 cm of recent snowfall, if a wind slab problem exists it will be confined to isolated pockets in the alpine.
