Deeper pockets of wind-transported snow can be found at higher elevations as storm snow continues to settle. Seek areas where the terrain is broken up into smaller features.
A thin snowpack has yet to cover early-season hazards.

Snowpack Summary
During Tuesday's storm, approximately 40 cm of light snow fell Tuesday evening. Although it has been relatively calm since the storm, the storm brought with it winds and has left alpine and treeline areas with pockets of heavily deposited snow. At higher elevations, the new snow and new wind slabs cover previous wind-affected snow. In more sheltered areas it buried a 2 to 5 mm surface hoar layer which is now buried. Further down in the snowpack there are reports of a melt-freeze crust. These layers
At around 1000 m the snowpack is reach depths between 70 cm. Lower treeline and below treeline elevation are still below the threshold for avalanches.
