Ongoing westerly wind has heavily impacted the snowpack . Westerly slopes are scoured and isolated wind slabs could exist on leeward aspects in the alpine and treeline. These slabs could overlie facets. The wind affect is most extensive on the east side of the Continental Divide.
At treeline and below a layer of facets over a crust, from early December, can be found down 40 to 70 cm.
The lower snowpack is generally well-settled.
Treeline snowpack depth varies significantly across the region, from 50 to 200 cm.
