Obvious signs of instability
|Recent Avalanches?||No||Collapsing (Whumphing)?||Yes||Cracking (Shooting cracks)?||Yes|
Small, shallow, collapses, shooting cracks <10' long, on 35*, E, 3500' on old, soft, weak, wind slab over rounding BSH, over MF crust, down 5-10cm,
Sky=Few 10am>Scattered>Broken S-1, light flurries, 2pm
Temp -7.7*C at 3700'
1/2"-3" new snow over MF crust
Most of the crust I skied on today was supportable. Unsupportable, breakable crust exists in specific locations
LOW COVERAGE, HS 2-29" @ 3000´-3706', East to South Facing
A generally shallow snowpack with dust sitting on crust over a sandwich of crusts and facets, sitting on weak, basal facets (2.0mm rounding)
Specific areas of isolated, small, old, soft wind slab sitting on rounding BSH 4.0mm, reactive to skiers weight, cracks <10', 5-10cm deep over crust. Some isolated, small, wind slab cracking deeper, down 15cm on faceted layer under crusts.
