Generally good ski quality. Heavier snow than past few days. Multiple avalanches reported N & AS. Snow increased throughout the day; however, winds remained lighter than recent days and wind loading was mostly confined to high elevation ridgetops. Multiple N avalanches observed, D1-D1.5 on E-NE aspects. There was 1 incident of a collapse at 9500' NE with no avalanche produced. There was cracking and small pockets releasing in steep terrain (35*+) and on convex rolls at mid elevation, 7500'-8500' E-NE. Multiple skier triggered avalanches reported; ASc-R1-D1 8500' ENE, ASu-R1-D1.5 9000' E.
