If you find yourself lost in the wilderness in the depths of winter, drop whatever you're doing and begin a shelter immediately. You won't have much sunlight and you don't want to stumble around in the dark. To learn to build one effectively, check out the video below.

This is a great lesson in how to construct one of the most effective winter shelters you could possibly hope for. What makes it so great? That fire reflector, of course!

If you need to rely on a winter shelter and a fire for survival, be sure to spend a little extra time on two things: padding your floor and building your fire reflector. These are the two things that are sure to save your life. But keep an eye on the sun; you're stretched for time in the middle of the winter.

This is an excellent lesson that everyone should be sure to learn. You never know when you'll need it.
