Wilderness Navigation Handbook

Relying heavily on graphics, this authoritative text covers more wilderness navigation topics than any other book on the market. It provides detailed technical descriptions of navigation tools — maps, charts, compass, altimeter, GPS, and sextant — and step-by-step procedures on how use these tools individually and in combination with each other. Factors that cause tools and techniques to fail are discussed.
 
One full chapter dwells into the complexities and limitations of celestial navigation, while another chapter describes natural navigation techniques — if you aren't carrying any navigation tools, don't give up hope.
 
The last two chapters deal exclusively with practical navigation. The last chapter, which is quite entertaining, describes real life scenarios, some of which the author has vividly experienced.
