First you'll need to find water. Water flows downhill, encourages vegetation, and collects in natural caches, be they ponds, lakes, rivers, springs, rock depressions, or even leaves. Unfortunately, most fresh water sources are not pure enough to drink from (as they used to be), so you'll need to know how to purify water under most situations. Use any of these methods to collect clean, purified water:
With a calm center, over half the struggle is over. As I mentioned earlier, the most common physical reason that people die in wilderness survival situations is exposure to the elements. A person can die from exposure in as little as three hours. You must learn how to stay warm when it is cold, how to stay cool when it is hot, and how to stay dry when it is wet. Enter the wilderness survival shelter. It can take many forms, with a classic one being the debris hut. The debris hut is a small, one person shelter that is basically a simple structure that cocoons a person in leaves, grasses, boughs, or other natural debris to keep them insulated. It is built to shed water. Just imagine a primitive tent and sleeping bag all in one.
Preperably a real snow cave, a quinzhee or a slope cave would be chosen, but those shelters are time consuming and requires some experience to do right, and in som areas like in the forest, it can be impossible due to snow depth, or to find a bank with enough drifted snow. Shelters like that are more useful above the tree-line were there are more snow and less vegitation.
If it’s the middle of winter and all available building supplies are frozen or buried under snow, remember that snow will have the same insulating effect as a stick-built shelter.
