Snowpack Summary
Storm snow overlies 30-40 cm of recent snow that was redistributed by strong southerly winds. At low elevations, storm snow overlies a surface crust from warm temperatures and rain.
A spotty layer of surface hoar can be found down 25-45 cm deep in sheltered terrain features at and below treeline. The distribution of this layer is not well known.
A layer of facets buried at the end of November can be found 100 to 200 cm below the surface. The snowpack depth varies between 150 and 250 cm at treeline.
