Over the last five winters, avalanches killed an average of 29 people per winter. Almost all are recreating. The typical avalanche victim in the US is male, between the ages of 25 and 40, and skilled at their sport. Most victims die from asphyxia, while one quarter to one third of victims die from trauma. The Colorado Avalanche Information Center is the central archive for avalanche accidents in the United States (link below).
