Comments
Triggered avalanche remotely from ridge line. Several hundred yards earlier we collapsed a similar slope and saw cracking (crown, flanks and would-be stauchwall) of a piece of snow that didn't quite slide.
Noticed another soft slab avalanche on Lackawaxen (east facing off Clayton peak).
also collapsing in lower elevation (8,800') north, and even in upper elevation south.
facets on all aspects, under friable crust on southwest.
