    Expect find fresh wind slabs on south and west facing terrain features. Older more stubborn wind slabs will be buried by new snow, they exist on a variety of aspects and may still react to human triggers.

Snowpack Summary

Up to 30 cm of storm snow can be found, affected by moderate to strong north/east winds at higher elevations. New snow sits over wind affected surfaces at higher elevations.

A melt freeze crust from mid January may sit just below the surface in exposed areas and around 30 cm deep in sheltered terrain, found up to 2100 m.

The mid snowpack continues to settle and is well consolidated. Facets exist near the base of the snowpack. Total snowpack depth ranges between 90 to 125 cm.

Confidence
