Observations
-At 7250’ noted HS of 200cm at a 210 degree aspect. Skies OVC, S-1, winds light below ridge lines, moderate gusts on ridgetops. No surface snow being transported.
-Hasty pits on ascent consistently sheared on buried crust 35-37cm below surface. Snow from 20230304-05 was forming a 4F hard slab above this layer. Most aspects receiving direct solar rays had a 1F hard layer approximately 4cm thick just below the surface. New snow over night/early AM left about 1cm on top of this sun layer.
-FC were found on the underside of this sun crust layer and failed on steep rollovers creating dinner plate size fractures on descents.
