Snowpack Summary
New snow and wind will likely build reactive wind slabs throughout the day. These slabs will be largest and most reactive on north aspects.
In the mid pack, down around 50 to 70cm, 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.
