Observation

Description of Snow, Weather, and Avalanche Conditions:

Went for a short tour up towards donner summit today to make informal and formal obs. We observed S-1 snowfall accompained by moderate W-SW winds. Snow was also observed blowing on ridges near treeline. Fist hard, unconsolidated snow existed on the top 30cm of the snowpack, followed by 4F down to 1F/P (total depth dug 140 cm, right-side up, no layers of concern.) Also we did not see any surface hoar present in this area. (Due to the flat light pictures of blowing snow did not come out well, chose not to post)
