Post 2/26 Storm Observations
Several natural storm slab and wind slab avalanches on mostly SE, S, SW aspects 2500′ to 4000′. Most avalanches appear to have failed on new snow/old snow interface. One low elevation (2500′) W aspect slab failed naturally below the Valentines Storm layer on persistent weak layer on crusts.
Avalanche Details
Multiple soft slab natural avalanches D1-D2 observed that went mid-storm 2/26.
Several dry loose avalanches.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Observer Comments
Recent avalanches. Significant snowfall 2/26 1am- 7am = 10"-12" new snow. Temperatues increasing throughout storm resulting in upside down snowpack.
Weather
12" plus new snow recorded at IM 2/26 . Winds G16-32 SSE,S, SSW then switched to N throughout storm.
Snow surface
New wind crusts on many surfaces from varying winds N through SSW during and after storm. Upside down snowpack from 2/26 storm.
