Location: Floor of Tuckerman Ravine

Strong west winds and blowing snow continued throughout the afternoon under clear skies. The snow transported by these winds is creating slabs of 1 finger hardness and varying thickness in steep east-facing terrain. These slabs are smooth, hollow, and for the most part unconnected across the terrain. The majority of the slabs are stubborn to triggering but in many areas the snowpack structure is strong over weak with facets near the base. Right and Left Gullies seemed to ski well for those braving the winds. Right Gully has been slow to fill-in but shows promise with continued northwest winds. There was not evidence of natural or human triggered avalanches today. The overall snow surface is an irregular mix of soft, 1-3 foot deep slabs of wind blown snow, wind scalloped depressions, and firmly pressed windboard. The Lower Headwall is still mostly unskiable with open water sections and exposed ice bulges.
