Avalanche Summary
Recent avalanche reports are limited to small, loose dry avalanches in steep, shaded terrain.
On Sunday in the Mt. Cain backcountry, there were reports of whumpfs and a large avalanche around treeline.
If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network)
Snowpack Summary
60 to 100+ cm of recent snow is faceting with cold temperatures, and getting softer from the surface down. This recent snow overlies a crust on all but high north aspects. At upper elevations, the recent snow has been redistributed by wind.
Below the crust, the snowpack is generally settled and strong.
Below treeline areas have now received enough snow to produce avalanches. Watch for "early season" type hazards such as shallowly buried stumps, rocks and creeks.

Terrain and Travel Advice
- Watch for areas of hard wind slab on alpine features.
- Be carefull around freshly wind loaded features.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Problems
Wind Slabs
Wind deposited snow from the recent storm may avalanche under the weight of a human. Cold temperatures have been keeping the surface snow loose, so anywhere that the wind starts to blow, touchy new wind slabs could form.
Aspects: All aspects.
