Snowpack Summary

Approximately 10 cm of new snow sits on a mix of sugary faceted snow, and hard wind affected snow. The new snow is likely being formed into wind slabs by strong westerly winds. The total snowpack depth is between 50-100 cm in the alpine, and tapers rapidly at lower elevations. Two crusts have been reported in the middle of the snowpack. There is uncertainty as to how well the snow is bonding to these crusts.

Problems
