Winter in the North American wilderness cannot be conquered. At best, it is endured. And only by those who will fight tooth and nail for the privilege of survival. Winter after bone-chilling winter, the Mountain Men have relied on ingenuity, tenacity and determination to weather the worst that the elements could bring to bear. But this season, that cold-forged mettle will be tested like never before.
