Quick Answer
SWIMING OUT OF AN AVALANCHE BURIAL IS RARELY POSSIBLE DUE TO THE LOW TEMPERATURES, PRESSURE, AND TURBULENCE THAT MAKE IT EXTREMELY DIFFICULT TO BREATH AND MOVE. --- Understanding Avalanche Burial
Avalanche burial can occur in as little as 10 seconds, with snow depths ranging from 1-30 meters. In such an environment, the air is colder than 0°C (32°F) and oxygen levels are significantly lower due to the weight of the snow.
Swimming in Snow
Even if you attempt to swim out, the snow acts like a dense, heavy liquid that can cause you to sink. The cold also causes your body to lose heat rapidly, leading to hypothermia.
Techniques for Escape
If you find yourself buried, your best chance of escape involves using the “breathing technique” or “air pocket” method. This involves exhaling slowly, which can create a small air pocket above your head. You must then use your legs to move upwards, creating a new air pocket, until you reach a point where you can exhale and inhale normally.
