What kills you in an avalanche?

People die because their carbon dioxide builds up in the snow around their mouth and they quickly die from carbon dioxide poisoning. Statistics show that 93 percent of avalanche victims can be recovered alive if they are dug out within the first 15 minutes, but then the numbers drop catastrophically.

What was the biggest avalanche ever recorded?

Why are there so many avalanches in Colorado?

Colorado gets so many avalanches for two reasons. First, it is a very windy state and it moves the snow around which creates more avalanches. Also the state's sunny winter weather melts snow during dry periods. This melted snow often becomes part of the unstable layers of slippery snow that can easily slide.

His work showed 56% of victims without a balloon pack survived, while 83% with a pack made it out alive.

Breathing under snow, e.g. while buried by a snow avalanche, is possible in the presence of an air pocket, but limited in time as hypoxia and hypercapnia rapidly develop.

What is it like to be buried in an avalanche?

People buried beneath avalanches often can't expand their chests to breathe as snow packs into their ears, nose, mouth and eyes, according to Greene. “If they can breathe, they're quickly inhaling the carbon dioxide that they're exhaling, and that's what kills them,” he said.
