Amazon Link: Wilderness Navigation
The National Outdoor Leadership School is a group that teaches college-aged kids outdoor skills. If you recall, I reviewed their Wilderness First AId Book. This is the second book of theirs I've read.
Again, this book is geared toward the hobby hiker or backpacker, and not anyone involved in anything remotely tactical. This is evidenced by it's insistence on staying on the trail to keep from getting lost, which is the last thing we would do.
