Roof avalanches have killed six people in the United States during four of the five last winter seasons. February 2019 was the second snowiest month on record in the Teton Range. An abundance of snow created an extended period when large roof slides were a serious hazard. Roof slides were mentioned on a near daily basis in daily avalanche hazard bulletins from March 17 through April 19. Significant property damage occurred to vehicles and structures during this period.
