    This layer is likely out of the ski triggerable range, however could be initiated as a part of a step down avalanche.

Avalanche Summary

Several large avalanches were observed from last weeks wind event, some failing to persistent layers. No new avalanches observed in the last 72 hours.

Snowpack Summary

Small wind slabs forming in the alpine with strong SW winds. Below 2000m a new crust exists from last weeks warms temps. The Dec 23 melt freeze crust and facets are down 40-100 cm. An early season basal crust complex exists in most places in the alpine and at treeline. Significantly less snow in the eastern areas of the park. Snowpack depths between 30 - 170 cm.
