Snowpack Summary

15 to 25cm of low density recent snow exists at all elevations. This recent snow will form new wind slabs in the alpine when the wind picks up. Underneath this low density snow a variety of surfaces can be found like old hard slab, facets and even bare ground.

In the mid pack it could be possible to find a thin layer of facets between old wind slabs. This layer recently produced sudden results in snowpack tests.

The height of the snowpack is variable. In areas lee of the prevailing wind, depths of up to 170cm can be found. At the lower elevation treeline terrain, snow depths decrease and are estimated at 60-90 cm.
