Snowpack Summary
Surface snow has been extensively wind affected by outflows on Monday followed by strong southwest flow Tuesday.
A shallowly buried crust (around 20 cm deep) extends up to at least 1200 m on all aspects. It appears to be well bonded to surrounding snow, and is beginning to break down. Below this, the mid-pack is generally well-settled and strong in most areas. The basal snowpack consists of weak, sugary facets.
Terrain and Travel

- Keep your guard up at lower elevations. Wind slab formation has been extensive.
- Watch for areas of hard wind slab on alpine features.
- Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
Problems
Wind Slabs
Recent wind direction has been variable so watch for wind loading on a variety of aspects. Likely features to find wind deposited snow include ridge crests and convexities. Whumpfing, cracking, and hollow sounds are all signs of instability that should cause you to back off into lower angle or less wind-loaded terrain.
Aspects: All aspects.
