This is the best book that I have ever read on survival. It tells eveything from how to build lean to's to log cabins to igloos. Also it tells how to build traps to catch animals and fish which is a must if lost in the woods. As well it tells every way imaginable to navigate and tell what your long and lat. are. It tells plants that youcan and cannot eat, how to clean your water, how to make bread, bows and arrows, bolas, survival strategies for the weather, and much much more. I would reconmen this book to any one who loves camping hunting hiking or any one who is interested in these sort of things
