Wind slabs have developed as the wind continues to transport low-density snow. Seek sheltered areas where the snow has not been wind-affected.

Early season hazards continue to pose a threat and are lurking just below the surface.

Avalanche Summary

A few small loose dry avalanches have been reported in the region. These have mostly been in the alpine and treeline elevations. If you head into the backcountry consider submitting a MIN report.

Snowpack Summary

At around 1750 m the snowpack sits at 110 to 170 cm. The top layer of light snow ranges between 20 to 80 cm with greater amounts towards the west. This new snow is sitting on a melt-freeze crust. Further down into the snowpack, 80 to 90 cm, there is a series of crust layers. The bond between these layers and the snow beneath them has been weak to moderate in strength. Near the ground, the snow is not bonding well due to early-season cold temperatures and shallow snow.

Terrain features still lurk below the surface. Below treeline and even into treeline elevations are still at below the threshold for avalanches.
