Here’s some guidance for surviving in cold and deep snow:
Shelter:
- Find Existing Shelter: Look for natural formations like caves, overhangs, or fallen trees that can offer some protection from wind and snow.
- Build a Snow Shelter: If you have time and energy, you can build a snow cave, quinzhee (a mound of compacted snow hollowed out), or a snow trench.
- Snow Cave: Dig into a deep snowdrift, creating a small entrance and a larger chamber inside. Ensure proper ventilation to avoid carbon monoxide poisoning.
- Quinzee: Pile up loose snow and let it settle for a few hours. Then, hollow out a space inside.
- Snow Trench: Dig a trench in the snow deep enough to sit or lie down in. Build a windbreak on the open side with snow blocks or debris.

Fire:
- Fire is Crucial: Building a fire will provide warmth and allow you to melt snow for water.
- Gather Dry Tinder: Look for dry leaves, bark, twigs, or anything that will catch a spark easily.
- Use Fire Starter Tools: If you have a lighter, matches, or a fire steel, use them carefully and conserve fuel.
Staying Warm:
- Stay Dry: Wet clothes lose heat much faster. Change into dry clothes if possible, or improvise insulation with dry leaves or grass.
- Layering: Multiple thin layers trap more heat than one thick layer.
- Body Heat: Huddle with yourself or others to share body heat.
- Improvise Insulation: Stuff your clothes with leaves, grass, or anything that can provide extra insulation.
Hydration:
- Melt Snow for Water: Use a fire, pot, or metal container to melt snow for drinking water. Be sure to boil it for at least a minute to kill bacteria.
- Hydration is Key: Even in cold weather, dehydration is a risk. Make sure to consume melted snow or water regularly.
Signaling for Help:
- Fire: If you have a fire, build a large, smokey signal fire.
- Mirror: Use a signal mirror to reflect sunlight towards potential rescuers.
- SOS Signal: Use branches or rocks to create a large SOS symbol on the ground.
Remember:
- Ration Energy: Don’t exert yourself unnecessarily. Focus on conserving energy for essential tasks.
- Travel During Daylight: Traveling in the dark increases the risk of getting lost or injured.
- Stay Put as a Last Resort: If you can’t find shelter or build a fire, stay put and conserve energy. Wait for rescue, but be prepared to signal for help.
