    You are more likely to trigger this layer below treeline where the upper snowpack is more consistently shallow and weak. You still need to be cautious in shallow areas above treeline.

Weather Forecast

Continued cold temperatures and some increased cloud cover into the evening. Forecasted temperatures averaging near -15 for the Icefields area. 

Snowpack Summary

The clear skies and light winds have created surface hoar from sz 1-4mm at all elevations. An overall shallow snowpack sits on 10-20cm of basal facets. Previous wind slabs provide bridging strength to the snowpack above treeline and into the alpine. Extensive scouring in the high alpine.

Avalanche Summary

No new avalanches observed.
