Avalanche Summary

No recent avalanches have been reported, however a few small wind slab avalanches have been observed in neighbouring parts of the North Rockies over the past few days.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

In the alpine, up to 15 cm of recent snow sits above a variety of old snow surfaces including wind-scoured snow and faceted snow. At treeline and below, the recent snow sits on a widespread crust.

The snowpack is shallow and faceted with multiple crusts. Pockets of deeper snow may be found near ridges, gully features, and established avalanche paths. Average snowpack depths at treeline average between 40 and 80 cm.
