Quick Answer
It's not safe to attempt a swim in avalanche conditions due to the high risk of being suffocated by avalanche debris, entombed in snow, or disoriented underwater. You may also experience hypothermia or cardiac arrest from the shock. It's crucial to find other evacuation options.
Understanding Avalanche Conditions
Avalanches can create massive walls of snow and debris that are impossible to swim through. The average avalanche can reach speeds of up to 80-90 mph (130-145 km/h) and bury a person under 10-20 feet (3-6 meters) of snow. Even if you manage to survive the initial impact, the force and weight of the avalanche debris can cause asphyxiation or crush injuries.
Evaluating Evacuation Options
When caught in an avalanche, prioritize finding an escape route or signaling for help. If you’re unable to move, remain calm and try to stay afloat by kicking and swimming upwards towards the surface. If this isn’t possible, signal for help by making noise or using any available objects to create a visible signal. Aim to stay above the base of the avalanche, where the snow is less dense and you have a better chance of being detected.
Swimming Techniques in Avalanche Rescue
In the unlikely event that you do find yourself in a situation where swimming through the avalanche is necessary, use the ‘swim-float-swim’ technique. Start by swimming downwards with your hands and feet extended, then float upwards with your arms and legs together. Repeat this process until you break through the surface or find a pocket of air. Remember that this technique is only a last resort, and it’s crucial to prioritize other evacuation options whenever possible.
