Avalanche Summary
Recent reports of avalanche activity have been limited to small (size 1) loose snow avalanches in steep, alpine features that face the sun.
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
Dry, powder snow remains on shaded (northerly) slopes. Moist snow or thin crusts exist on solar slopes and all aspects below ~1700 m.
The mid-snowpack is generally well-settled.
The lower snowpack includes a layer of weak sugary crystals near the ground. This layer has not produced recent avalanche activity in this area, but professionals continue to monitor for signs of it becoming active.

Terrain and Travel Advice
- Pay attention to isolated alpine features as well as cross-loaded features at treeline.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
Problems
Wind Slabs
Dry, soft snow persists at high elevations on shaded slopes. Moderate southwest wind in the alpine has the potential to form reactive windslabs in leeward terrain.
Use extra caution below ridgecrests and in cross-loaded features. Watch for signs of instability like shooting cracks.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
