Snow Characteristics Comments
Snow best described as variable below summits on northern aspects, with areas of loose settled powder present, areas of denser wind-affected snow, wind-scoured areas, and areas of wind slab. Surface inch or two on southeast aspects beginning to corn up. New settled dense snow is pretty shallow on west aspects atop the extremely bonded and dense old snow. The deep snow we have been observing during this storm in eastern areas of the range this week is not evident in the western section we explored today. This could be related to lake-effect as much as the strong winds that affected the western side of the Bear Rivers (see Logan Peak weather station data).

Wind Loading
Red Flags Comments
A pocket of wind slab noted immediately below ridge on north aspect. Wind slab formation appeared to be maybe 8 inches deep, however, this pocket was isolated to a single chute, with adjacent chutes showing no evidence of wind slab formation. Wind direction was so variable during recent storm that wind-loading was not apparent below ridges and no new cornice formation of any significance was noted.
