Avalanche Summary

No new avalanches were observed.

Snowpack Summary

This last storm has left us with 10-25cm of snow, more towards the East of the Park. The alpine has variable distribution of snow from 60-150cm of depth due to several wind events over the last couple of weeks. The alpine has a lot of good skiing in sheltered areas. Some alpine areas have extensive wind slabs (producing easy to moderate sheers) with the reverse loading from the recent easterly storm. This recent storm snow sits on previous hard wind slabs that are "drum" like sounding. The snow coverage below tree line is still slim, thus making travel challenging.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
