General Snowpack Structure: 
  • Snowpack consists of several meters of recent storm snow on top of old snow from Oct/Nov. Those old layers are now so deep it is difficult to get any force down to them.
  • Strong winds at all elevations produce wind-affected surfaces even in sheltered areas. 
Weather Events: 
  • Strong SW winds with clear weather through 12/21.
  • Another large multi-day storm started during the night on 12/21 with a mix of rain and snow. Snow levels fluctuated between 7000 and 8000 ft. Gale force SW winds accompanied the storm.
