The Big Three of Survival
For hunters who get lost in the woods, the big three of survival are shelter, fire and signal. Water and food are important, but not as important as these top three needs. Let's review each right now.
This will protect a hunter from the elements. Natural shelters can be rock overhangs or thick evergreen trees (e.g., balsam fir). A man-made shelter can be as simple as a garbage bag, poncho or space blanket, or more elaborate, such as a debris hut or a lean-to. Depending on the shelter you build, make sure it is clearly marked with blaze orange or a color not normally found in the woods. To mark a shelter you can, use blaze orange flagging tape, a blaze orange vest or some article of clothing that is brightly colored. Rescuers will see the color and check out the site.
During the winter months materials to construct a shelter can be hard to find, therefore using the snow around you to build a shelter can protect you from the elements. Either using a snow drift, or piling snow into a large pile, a snow shelter can be constructed to help you survive if lost in the woods. Make sure to clearly mark your location with blaze orange flagging tape so that rescuers can easily spot your location.
