    This is a complex problem. The spacial variability and potential consequences of triggering a large avalanche on this layer makes it extremely difficult to gain confidence in the snowpack. Consider this before entering large features.

Snowpack Summary

Today's extreme winds have created wind slab (Soft to hard) tree line and above. Most fetches are stripped. This overlies a weakening mid-pack comprised of varied facet forms. This provides some questionable bridging over the basal facets and DH.

HS average at TL: ~145cm

Avalanche Summary

A road patrol down Ice fields parkway today noted a few Size 1 loose dry avalanches out of steep rocky terrain.

A Sz 2 wind slab avalanche was also observed off Mt Hardisty NW alpine face
