You can reduce your chances of being caught in an avalanche during winter mountain hikes by keeping the following tips in mind.
You can reduce your chances of being caught in an avalanche during winter mountain hikes by keeping the following tips in mind.

Avoid hiking immediately after a storm. Most avalanches occur at the time of or shortly after a heavy snowfall.
Avoid slopes with pitches greater than 25 degrees.
If you must traverse a steep slope, cross at the highest point possible, one person at a time.
Stay on the windward side of gently sloping ridges. The snow is usually thinner there.
Avoid treeless slopes and gullies. The absence of trees may reflect that previous avalanches have occurred in the area.
Watch for cracks or small slabs that have sheared off.
Listen for hollow or thumping noises as you walk.
Use a collapsible shovel to dig frequent snow pits. As you check the structure of the snowpack, be on the lookout for weak layers.
In 1970, an avalanche in Peru killed nearly 20,000 people.
