The north face of Cedar Mountain avalanched full depth sometime on Jan 1 or morning of January 2. This slope is called "Dirty Bowl" and it appears an impact crater (rockfall, cornice fall) may have triggered the slide. Photo: Big Sky Ski Patrol

This big natural avalanche on the East aspect of Emigrant Pk is outside our forecast area, but reminds us that snow is unstable in our surrounding areas. It likely ran Saturday or Sunday from a wind loaded NE aspect below the summit into low angle terrain, at least 2500' vertical total. It completely crossed a previous group's skin track and ski tracks. Photo: J. Curry

This slide was triggered with explosive by Big Sky ski patrol on 12/30. It broke on old, weak snow over the Thanksgiving crust 3-4' deep. Heavy snow and wind loading pushed deeper instabilities to a breaking point in isolated areas. Photo: BSSP
