説明
No one expects tragedy when out for sport or fun. But unstable snow is a huge danger. The power of snow can snuff out life. An avalanche can come with no warning. Riding snow in the mountains means risking your life. An avalanche can race at 200 miles an hour or more. It can crash with 50 tons of force per square yard. Not all avalanches are large. Not all are fast-moving. But whatever the speed, it's too fast for anyone in the way. Avalanches are White Death.
