Snowpack Summary
The top 30cm remains unconsolidated except where exposed to wind and soft slabs may have been formed. The snow depth is variable at all elevations. There is a crust/facet layer distributed through the region in the mid-pack with mixed reactivity and a weak basal facet/depth hoar layer at the base of the pack.
