Snowpack Summary
Recent snowfall has brought 25 to 40 cm of fresh snow in localized areas. The southwest wind has redistributed this new snow, forming deeper deposits on leeward slopes at higher elevations.
Below the new snow, a thick melt-freeze crust exists below approximately 1500 m.
The mid and lower snowpack is generally well-settled and stable.
Snow depths at treeline range from 120 to 180 cm.

Terrain and Travel Advice
- Keep your guard up as storm slabs may remain sensitive to human triggering.
- Seek out sheltered terrain where new snow hasn't been affected by wind.
- Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
