Notably less storm snow deposited/remaining in Huntington Ravine. Avalanche path development resembles pre-storm conditions.
Naturally triggered, suspected to have occurred yesterday or last night (1/11-1/12). Visually observed from Hermit Lake. Crown width approximately 300’, height approximately 12”.
looks like a recent slide, maybe a day or two old.
Pit Location was around 3500′. Results were ECT N. The layer of concern was a thin layer of small facets (4finger-Fist hardness) resting on the Christmas freezing rain crust. The snow pack, about 24″ deep, above this facet layer was right side up . . .
Naturally triggered avalanche occurring likely Wednesday evening, January 9 or possibly January 10. Looking up the gully, start zone obscured by blowing snow. Debris heavily wind affected. It appears that the avalanche ran from above the Christmas . . .
Signs of widespread avalanche activity some of which was large, following snow and wind during the past few days. Observed wind scoured debris in the following locations:
Lobster Claw – D2
Floor (from Headwall) D4
Left Gully D2
Empress . . .
4000” due east aspect, test slope next to the patrol shack. I ski cut the slope with shooting cracks and a big slump. The stanch wall broke and developed. But the slope stop before it enter gliding motion.
Surface of the snowpack consists of old melt-freeze crusts, older wind slab and wind slab that formed yesterday from 5″ of snow combined with high wind.
Naturally triggered avalanche, suspected occurrence late Sunday 1/6 or early today. Crown partially refilled by wind loaded snow, debris heavily wind affected. As seen in the picture, a line just below the ice and above the prominent crown line may . . .
Varying hardness (1F-4F) new wind slab, relatively smooth and consistent except in upper portions of terrain where scouring occurred. With incoming snow and wind, it’s worth noting this widespread smooth and firm nature as a potential avalanche bed . . .
