Why is an avalanche dangerous?

Avalanche facts Safe avalanches may be triggered in dangerous snow packs. Avalanches can travel up to 90 km/h. After one hour, only one in three victims buried in an avalanche is found alive. The most common causes of death are suffocation, wounds and hypothermia.

How can we prevent avalanches and landslides?

Prepare for landslides by following proper land-use procedures – avoid building near steep slopes, close to mountain edges, near drainage ways or along natural erosion valleys. Become familiar with the land around you. Learn whether debris flows have occurred in your area by contacting local officials.

How do you test for an avalanche danger?

Dig a pit 5 feet deep or to the ground (whichever comes first) on an open slope after probing to see if there is any old avalanche debris, rocks or brush in the way. Make the face of the pit smooth with your shovel. Use a glove to brush the surface of this wall to see if there are visible layers.
