Snowpack Discussion
Up to 35 cm of moist storm snow overlays well developed surface hoar, faceted snow, and sun-crusts on steep south aspects. Previous strong SW winds have formed windslabs in alpine and tree-line locations. The mid and lower pack is generally weak and faceted. Snow depths range from 40-60 cm at tree-line and up to 90 cm in deeper alpine locations.
Avalanche Activity
Numerous natural avalanches up to size 2 were reported on Tuesday running as storm slabs and deep persistent slabs at all elevations. Widespread whoomphing and cracking was reported in areas not steep enough to avalanche.
