Comments
I triggered this avalanche remotely from over 100 feet away while traveling on skis on a safe low angled ridgeline. I was walking along looking at north facing terrain when the slope made a loud "whoomp" and collapsed causing the avalanche. It was about 3 feet deep, 150 feet wide and ran about 150 feet.
The collapsing was the weak sugar snow near the ground from October. It is not uncommon to trigger avalanches from a distance when a "persistent weak layer" of sugary faceted snow is present in the snowpack.
