Big Sky Ski Patrol reported two natural avalanches seen today (12/15) in closed terrain.
From email:
"It looks possible that they released at two different times during the day today.....It looks to be the storm snow, which was sitting on lower-density snow at the old snow interface. That interface likely had a layer of faceted snow on top of the old, crusty snow. " Photo: Big Sky Ski Patrol
