Avalanche Activity

Snowdrift accumulations on east-facing slopes

Avalanche danger above the treeline is moderate. Avalanche prone locations occur on N/NE facing slopes more than anywhere else. Fresh snowdrift accumulations have been generated, can be triggered even by the weight of one single person. Special caution is urged at entry points into gullies and bowls (shallow to deep snow).

Snowpack Structure

The huge amounts of snowdrifted masses from the last few days have been able to settle. More deeply embedded inside the snowpack are layers of faceted crystals and melt-freeze crusts which weaken the entire snowpack. On steep south-facing slopes a melt-freeze crust has formed. Fresh snowdrifts from NW winds lie deposited on east-facing slopes atop surface hoar.
