The Rogers Pass accident is the deadliest avalanche accident in Canada and a defining moment in the nearby town of Revelstoke. On day six, slides destroyed buildings in Wellington, Washington, on the west side of Stevens Pass, killing 98 people. The event remains the deadliest avalanche in North American history A worst-case avalanche scenario is most likely to occur in the Western Cordillera, resulting from a single large-scale weather pattern, where a cold period resulting in the development of a weak layer in the snowpack is followed by a series of major mid-winter storms. Emergency preparedness for avalanches is most advanced in western Canada Avalanches can occur anywhere in the world where there is snowfall buildup at a particular angle. The Alpine countries of France, Austria, Switzerland and Italy have the greatest number of avalanches and loss of life annually.

7. Myth: The East's Comparatively Minute Snowpack Makes Avalanches Less Deadly. The East Coast may not have the dense snowpack of the west, but we do have an abundance of trees and rocks. While asphyxia is the primary cause of death of avalanche victims, trauma accounts for about a quarter of avalanche fatalities. 8 Avalanches may be triggered on many slopes even if only light loads are applied. On some slopes, medium or even fairly large spontaneous avalanches may occur. 4 - High: On most steep slopes the snow is not very stable. Avalanches are likely to be triggered on many slopes even if only light loads are applied Avalanches will often fracture directly at or just below the roll. Concave slopes, where the slope gradually flattens as it descends, are generally safer, as are planar slopes, which are slopes that maintain an even angle. But if a slope is steep enough, avalanches can occur regardless of the slope's shape Approximately 1,200 kilometres of provincial roads are prone to the danger of avalanches in 60 hazardous areas, including Kootenay Pass, Bear Pass, the Trans Canada Highway near Revelstoke, Allison Pass, the Fraser Canyon, the Coquihalla, Duffey Lake Road and Highway 16 between Terrace and Prince Rupert
