Snowpack Summary
At treeline and above 10 to 20 cm of recent snow sits above a widespread crust and may show a poor bond. Below the crust is a layer of moist snow. The new snow tapers with elevation loss but the surface crust continues to exist below treeline. This crust should provide a bridge over any previous layers of concern deeper in the snowpack.

Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Avoid areas where the snow feels stiff and/or slabby.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Problems
Storm Slabs
In any alpine areas where a crust at or near the surface does not exist, reactive storm and wind slabs may persist.
