>>544958My Side of the Mountain FTW. Favorite book of all time.
Also:
Into the Wild (of course)
The Tracker - Tom Brown Jr. Follows the author's intense spiritual and skillful journey to become the world's best tracker and among the best survivalists.
The Search - Tom Brown Jr. A continuation of the former.
The Crossing - Cormac McCarthy. A teenage cowboy's grueling adventure into the Animas mountains of northern Mexico to track and a kill a strangely intelligent wolf. Shit goes far beyond that only a fourth of the way in. A slow, unforgiving, introspective book.
Stickeen - John Muir. Novelette following a fictional adventure Muir has on an expedition to the coasts of Alaska, where he and an introverted young mutt go on an adventure together to a glacier and form a strong bond.
The Last of a Breed - Louis L'Amour. A half-native American fighter pilot goes down and is captured in Soviet Siberia. The book follows his months' long escape to the US, as well as the story of the Soviet commander trying to hunt him down to earn a spot in the Moscow government.
Coyote - Wyatt Widmer. One I found on Amazon as an e-book. Follows the coming-of-age through nature and adventure of a hyper-independent teenager who thinks too much for his own good. He gets into bad situations and some really cool ones.
Then of course, there's Walden, My First Summer in the Sierra, and the other Transcendentalist writings (except by Emerson. Fuck that guy.)
