Snowpack Summary
Winds are expected to have created redistributed recent storm totals into deeper slabs on north and east facing terrain features at higher elevations. The upper snowpack is generally faceted. At treeline, expect to find a surface hoar layer buried around 50 cm deep.
The mid-pack is generally unconsolidated. A crust with sugary facets beneath it can be found just above the ground.
The snowpack is still shallow for this time of year. Average snowpack depths at treeline range from 55 to 80 cm.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
