Snowpack Summary

Snowpack continues to settle due to Diurnal conditions. Scoured from previous winds. Old hard slabs exists in the alpine and open tree line. More confidence in the southern snowpack. Cornices remain an overhead hazard,

The mornings can provide good travel on the melt freeze crust. By early afternoon the crust will start to break down.
