Falling tree triggered avalanche

Eric Knoff investigates an avalanche in Lionhead on a wind-loaded slope that was likely triggered when the tree behind him fell from the epic winds. The avalanche was small (1.5' deep, 75' wide, 100' vertical) and failed on a layer of facets on top of an ice crust. Photo: GNFAC
