Snowpack Observations

Details

Conditions from 7,000-10,000 ft in the Old Ski Bowl after yesterday's storm:

  • Height of new snow (HN): 2-3 in.
  • Snow surfaces above 9000 ft remain scoured and icy. Strong NW winds blew all the new snow to lower elevations.
  • Wind drifts and small cornice formations 12-18 inches think were found on S-SE-E aspects between 7500 ft and 9000 ft. The amount of drifting in these isolated areas was impressive considering the amount of new snow received. Cornices broke easily with the weight of a person (see video).
  • Isolated, small and inconsequential windslabs 2-4 inches thick and 1 finger (1F) hard were found in the same elevation band and on similar aspects.
