Snowpack Observations

Details

HS 150cm and 15-20cm HN.  Small column tests and hand shears resulted in failures with easy force (x2) and failures on isolation (x2) on a density break within the storm snow 15cm down from the snow surface.  Winds from the S, SE, E, NE were observed throughout the day and snowpack loading was most obvious on westerly aspects with drifts measured 30-60cm. Freezing rain in the afternoon capped the snow surface with a 4F hard zipper crust.  No avalanches, shooting cracks, or collapses were observed.
