World's Greatest Single Avalanche
The world's greatest single avalanche disaster occured in Peru in 1962. 8 villages and towns were destroyed in just 7 mintues and more than 3500 lives were lost. The avalanche finally stopped after travelling 10 miles with the pile of snow over 60 feet deep. The victims could hardly move. Many died from the cold, lack of oxygen or injuries. Of all the victims, only about 5% were rescued.
Avalanche Control in Canada
One of the world's largest anti-avalanche programs is operated at Rogers Pass in Canada's Selkirk Mountains. Soldiers use gunfire to release avalanches and protect a 25 mile stretch of road from 160 separate avalanche paths.
