Wilderness Survival Shelter Basics
By Jason Knight
Understanding how to create effective wilderness survival shelters is one of the most important outdoor skills. From keeping you protected from the elements to providing a place to rest, wilderness shelters serve a key role in survival situations. Not only do they provide for physical needs, but also help create a sense of home in the wilderness. Though each season and environment presents its own challenges, there are several universal principles for creating effective wilderness survival shelters:
Location
The most important aspect of making wilderness shelters is choosing a good location. A good location is one that 1) provides easy access to ample building materials such as dead sticks, leaves, and grasses; and is 2) away from major hazards such falling branches, pooling water, and insect nests. You also want a location that has a large enough flat area to allow you to lie down and sleep comfortably.
Size
A common mistake when building wilderness survival shelters is to build them too large. Not only does it take more materials, effort, and time to construct, but often ends up being cold due to the amount of space on the inside. Effective wilderness shelters are often small on the inside - just large enough to fit your body to conserve body heat.
Structure
All shelters need to be constructed with safety in mind. Large strong branches can provide the initial framework for many types of survival shelters. Typically, branches used for framework should be strong enough to easily support the weight of an adult. This is especially important for lean-to and debris hut style shelters.
Insulation and Cover
Whether you are in a hot and sunny environment or a cold and wet forest, insulation and cover is important to keep you protected from the outside elements. Leaves, grasses, small sticks, ferns, and pine needles are types of debris that can be used for insulation. Be sure to layer large amounts of debris on your shelter. Also, don’t forget to use debris to create a thick mattress on the inside of your shelter to insulate you from the cold ground. Bark or soil can be added on the top and sides of your shelter to create a barrier from cold wind and rain.
Heat Source
In cool and cold environments the primary shelter concern is staying warm to avoid hypothermia. With wilderness survival shelters, there are typically two choices for a heat source: your own body heat or heat from a fire. Wilderness shelters that rely on your own body heat as the primary heat source (such as a debris hut), need to be small on the inside and have lots of extra insulating debris (imagine your mummy sleeping bag with ten times as much insulation). If you plan to use a fire on the inside of your shelter as a heat source, carefully plan how it will be tended all night, be sure to collect a full night’s worth of firewood before dark, and be extra careful not to burn down your shelter!
Types of Shelters
The type of shelter you choose depends on many factors including what materials are available, environmental conditions, choice of heat source, and whether it will be a personal or group shelter. A great personal shelter heated by your own body heat is a debris hut.
