This slide appeared to be triggered by a falling cornice. It broke near the ground and propagated two hundred feet wide. It snapped trees and left a debris pile up to ten feet deep. This avalanche illustrates that large and dangerous avalanches remain possible in the southern Madison Range and mountains near West Yellowstone. Photo: GNFAC
