Staying alive in the wild include emergency shelter building. The Debris Hut is an example of a survival shelter that can be built without saw or ax. All you need is an abundance of debris at hand. Make sure the spot you choose for your debris hut is plentiful in leaf litter. The lack of leaf debris will make this shelter useless in wet and wintry conditions. Emergency survival shelter training will prepare you.
Some shelters can be built with no tools. These are important survival skills to learn.
During freezing conditions when enough snow is available the snow cave will save your life. Especially if you need shelter above timberline. On the ridge of a mountain for example. The best way to dig a snow cave is with a snow shovel. But, if you don't have a snow shovel, you can use snowshoes, tent poles, or your hands to dig.
Emergency survival shelters
For shelters to be effective, you need to have plenty of needed material on hand. As an example, lean-to shelters use copious amounts of firewood to heat the whole front of the Lean too. A good rule of thumb is to estimate the amount firewood you will use, then double or triple that amount.
Shelters built-in low areas along rivers and streams will flood. Standing dead trees, stinging insects, and poisonous plants all pose a risk to the unwary. So, a good shelter in a poor location is still a poor shelter. Survival skills teach you this. Shadow Wolves
