Arctic health: Wilderness survival


Snow Igloo


– In Arctic conditions you need warmth or protection from wind and snow, preferably both. The wind chill factor makes the cold experienced much colder

Moderate zone: Skin exposure for 1 hour
Severe zone: Skin exposure for 1 minute
Extreme zone: Skin exposure for 1 second

– Don’t build the shelter in ditches. Water tends to accumulate there and it is frequently colder in the dips ands throughs. The shelter should preferably be near water

Snow Shelter
Note the snowwall that you don’t tread on your roof, ventilation holes, the lowest layer traps cold
Sleep one layer higher

-Don’t build the shelter on exposed, windy ridges

Emergency survival
Note feet in ruck sack
Material cloths packed in armpits
Back to the wind

-Snow can trap heat generated by the body but when the body touches snow, it draws heat out

Snow shelter, made with a covering sail

– Building of snow shelters, snow caves, snow domes (qyinzhees) and igloos are an essential survival skill

Snow Igloo: note that the door is surface height. Consider making the door sub-surface height
