Avalanche Summary

No recent avalanches have been reported, although observations are limited right now. If you see anything while out in the field, please consider sharing that information with us and fellow recreationists via the Mountain Information Network (MIN).

Snowpack Summary

Strong Chinook winds and steady snowfall will continue to form wind slabs in open terrain this week, especially on the Alberta side of the continental divide

There is wide variation in snowpack depths across terrain and throughout the region. In general, 50 to 100 cm of snow may be found in terrain depressions in the alpine, while very little snow exists on exposed terrain features. There is little or no snow below treeline.

There may be a crust near the middle of the snowpack, which could act as a sliding layer for the snow above it. The remainder of the snowpack has been reported to be relatively strong in deeper snowpack areas and weak and soft in shallow snowpack areas.
