Skurka's 2010 trip took him on a massive loop from the Arctic city of Kotzebue, passing beneath Mt. McKinley, traversing the Brooks Range, and crossing the Yukon Arctic and Arctic National Wildlife Refuge. The trip was humbling, even for Skurka, whose previous adventures in the last decade include the 6,875-mile Great Western Loop trek that won him National Geographic's 2008 Adventurer of the Year honors and the 7,778-mile Sea-to-Sea trek that he completed in 2004, linking five trails in the National Trails System.
While you're in the shop, ask Skurka for tips on gearing up and packing light: He's an expert in getting by on bare minimums and you'll want to be, too, if you're planning on even a fraction of his mileage. His new book Hiking & Backpacking Gear: A Walker's Complete Guide comes out next month.
