Snowpack Observations

We went on an exploratory tour in Lundy Canyon today. Starting at the dam and heading SE up the moraines to a higher elevation low angle open area. Below 8400′ there was about 40 cm of new snow from the last storm just barely covering bushes and rocks. Not much pre-storm snow underneath. Once on top of the moraine, the cover became better. The old snow from November is faceted and unconsolidated. It is filling in the spaces around the bushes. The old pre- storm snow surface provides an about 5 cm 4F hardness lid over these bottomless facets and bushes. New snow from the most recent storms accumulated to between 20 – 60 cm deep. The winds yesterday scoured ridges and deposited the snow in depressions and bowls. Skiing quality was surprisingly good and the wind rippled snow surface was mostly soft and creamy to ski in. We heard many Whumpfs on our way up the low angle terrain and saw a few isolated shooting cracks around our skin track in the new, wind deposited snow.
The structure of the snowpack is definitely weak and if we get more snow on top of this faceted and bushy base we could see more avalanches.
