Snowpack Summary
Localized winds have created isolated wind slabs on exposed alpine features. 10 cm of unconsolidated snow is found in sheltered areas. Below this is 30 to 50 cm of settling snow. Below 1500 m elevation a previously moist surface is now dense and refrozen.
The mid and lower snowpack is generally well-settled and stable.
Snow depths at treeline range from 140 to 220 cm.

- Carefully evaluate steep lines for wind slabs.
Avalanche Problems
Loose Dry
Unconsolidated snow that has been protected from the wind is likely to sluff in steep terrain features. Use good group management techniques to avoid being caught out by sluff and avoid terrain traps, especially cliffs.
