Snow Profile Comments
Thin layer of sugary facets (from Oct) near ground with recent storm totals. The Crown was 2.5 ft deep.
Comments
A North facing aspect with an exposed ridge into tight pines (200 ft), to a small opening (100 ft section where the slide occurred), to 2nd small patch of pines (Google maps shows it perfectly). The upper exposed section had a fair amount of whoomping but the snow-pack in the pines was much more stable. The slide broke right as the first skier left the first set of pines and entered the clearing. The fracture was about 100 ft wide and ran about an equal distance where it was stopped by the second set of pines. It was about 2.5 ft deep and ripped everything right to the ground.
