Observations
Snow was coming down heavier than expected all day given the forecast of tapering showers. Up until about 3500' there was very clear evidence of rain on snow from the previous night. We dug a pit at 4080'. The only visible layer was the 12/21 crust, and we did not get a result with a compression test. The top ~6 inches was much lighter fist-density storm snow, everything else was finger-density and well consolidated. Our biggest concern was deep snow immersion higher up and open creeks/tree bombs lower down as the snow changed to rain. The skiing was knee to thigh deep and very heavy.
