Everything about Alaska is larger, tougher, and more extreme than any other state. This breathtaking two-part journey soars over its one-half million square miles of winter wonderland and shows why countless adventurers have come to the 49th State over the centuries in search of gold, silver, mountain-peak views, dog-sledding glory, and more.
