Snowpack Observations

Details

  • Height of storm total since 03/13: 60cm above 7000ft
  • No avalanches or signs of instability
  • The new snow is right-side-up and well bonded to itself and the old snow surface
  • Minor wind loading and small wind lips observed above treeline on S-SE-E aspects
  • No wind slabs observed
  • Roller balls on steep south aspects below treeline in the afternoon
  • Dry snow surfaces above 7500ft with 20cm of ski penetration
  • Height of snow ranged from 120-200cm between 7000-9200ft
  • Ski quality was good. Brief periods of sun caused snow surfaces to become moist below 7500ft on south facing aspects in the afternoon
  • Compression tests resulted in non-planar breaks within the top 60cm of the snowpack. Extended column tests resulted in no fracture (ECTX x2)

  • Issued by Nick Meyers - Shasta-Trinity National Forest

LOW danger and normal caution is advised for today.  If and when we see wind speeds increase on Mount Shasta,  fresh snow remains available for wind transport. Leeward slopes above treeline could see active wind loading and the avalanche danger will rise on those slopes. Triggering a wind slab is unlikely at the moment, but pay attention for changing conditions should winds pick up over the next couple days.

 

 

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

We dug 2 pits at 6700' and 7000' on the west aspects we skied. There was around 20" of new snow from the past 3 days. High winds were recorded 3 or 4 days ago. An extendened column test resulted in no fracture (ECTX).
