Snowpack Summary

The top 30cm remains unconsolidated except where exposed to wind where soft slabs 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.

Avalanche Summary

Field day to Parkers Ridge area. Several loose dry up to size 2 were noted out of steep, rocky solar terrain. The visibility was good and nothing else was observed.
