For men who carve out their existence through sheer perseverance, conquering winter’s wrath has become second nature. But the challenge grows greater with each passing year as conditions on the frontier become more unpredictable and the modern world grows larger, more connected and more disconnected from our primitive roots. More people than ever are plugging in and tuning out the natural world, making it harder than ever to live the life of a Mountain Man. But even as the specter of progress bears down on these veterans of the wild, a new crop of challengers are rising to join the fight and preserve the ancient ways of the mountains against all odds. In Alaska, North Carolina, Montana and Arkansas, both the experienced hands and the new blood must push themselves to the limit to survive the coming winter and to defend the endangered spirit of freedom as the lure of urban life closes in around them.
