FINDING NATURAL SHELTERS
Using landscape features can help you find shelter more easily
TREE BOUGH ENVIRONMENT: JUNGLE OR FOREST
You can easily shelter under the bough of a tree, especially if it has fallen over naturally, or you can tie down a bough. Bough shelters are good camouflage.
CAVE ENVIRONMENT: ANYWHERE ROCKY
A cave is an ideal shelter as it offers a roof, fairly constant temperature and is secure. However, you need to look out for other occupants, like snakes and bears.
NATURAL HOLLOW ENVIRONMENT: TEMPERATE
A shallow depression in the ground will offer you some shelter from wind. You can also cover it with branches, grass, turf and bark to deflect rain and sunshine.
TREE PIT ENVIRONMENT: ARCTIC
If you see a tree with thick lower branches surrounded in deep snow, you can dig a pit near the trunk to shelter in. Keep it small to retain heat.
