Quick Answer
If a snow cave begins to collapse, immediately exit the cave through the entrance, not through any other openings that may be blocked by falling snow, and move to a safe location.
Assessing the Situation
When a snow cave starts to collapse, time is of the essence. Quickly assess the situation to determine the extent of the damage. Look for signs of structural failure, such as cracks in the walls or ceiling, and listen for the sound of shifting snow. This will give you an idea of how much time you have to react.
Exiting the Cave
Once you’ve assessed the situation, it’s time to exit the cave. Move quickly and calmly to the entrance, avoiding any areas where the snow is loose or unstable. If the entrance is blocked, look for alternative exits, but be cautious not to create new openings that could make the situation worse. As you exit, be prepared for a possible snow avalanche, and move to a safe location, such as a nearby ridge or a snowbank, where you can assess your next move.
Finding a New Shelter
After exiting the cave, you’ll need to find a new shelter. Look for a location with a stable snowpack, such as a slope with a consistent angle, and a surface that’s not too steep or too flat. Use your knowledge of snow characteristics to determine the best location. For example, a north-facing slope will be more stable than a south-facing slope, and a slope with a consistent angle will be more stable than one with a steep or flat surface. Once you’ve found a suitable location, use your snow anchors and ropes to secure your new shelter and keep yourself safe.
