Avalanche Details
From what I was told later, this avalanche was skier triggered. Propagated just below the ridge line and ran to the valley floor. Soft fast running snow. As seen in the video I'm standing in the valley floor. My group of 4 (2 skiers, 2 splitboarders) pushed the skin track back an additional nob from where numerous groups were farming the sunny west face. Dropping in first I expected snow to move at some point. Which it did, 80% down my line. 6-8" deep, propagated to about 50 feet wide. Second skier from our party kicked of a similar slab 2 turns into his line that ran about 100 feet. Before our 3rd member dropped in the ridge to our lookers left started to sliding and propagating......
Our other 2 companions then rode down without incident.

Observer Comments
Numberous crowns from weekend slides. All activity as of late appears to be human triggered.
Weather
Some wind effect. Mostly clear skies, -12c. Ridge top and valley wind.
Snow surface
Settling dry pow, slightly wind churned. Touchy light footed, waiting to hit the gas peddle type riding.
