Observation Date: 01/01/2012
Route/Location:
Wahoo Pass above Mud Lake
Weather:
Clear, sunny, temps in 20s, no wind
Wind:
No wind loadingThe addition of weight on top of a snowpack, usually from precipitation, wind drifting, or a person.The added weight of wind drifted snow. visible
New Snow: 12+”
Snow DensityThe mass of snow per unit volume, but often expressed as a percent water content. New fallen powder has a low densityThe mass of snow per unit volume, but often expressed as a percent water content. New fallen powder has a low density (3-10%), while heavy or wet snow is more dense (10-20%). (3-10%), while heavy or wet snow is more dense (10-20%).: Low
Avalanche Activity:
No visible cracking, whommping, or signs of instability.

Total snow depth 220cm with two buried layers 120cm and 200cm.
Other Comments:
StabilityThe chance that an avalanche will not occur, relative to a given trigger (usually the weight of a human). much better than expected but skied low angle meadows to be sure.
