Driven by his calling to explore the Arctic wilderness, Dave Metz packed up his two beloved airedale dogs, a sled, 50 pounds of food and set out on a 600-mile adventure across the Gates of Alaska national park, one of the least travelled regions in the world. More people have landed on the moon than have completed the four-month journey Metx made across the inhospitable terrain. Crossing the Gates of Alaska is Metz's candid and stunning firsthand account of his astonishing physical, mental and spiritual feat.
