Covering vast distances in time and space, Yukon: The Last Frontier begins with the early Russian fur trade on the Aleutian Islands and closes with what Melody Webb calls "the technological frontier." Colorful and impeccably researched, her history of the Yukon Basin of Canada and Alaska shows how much and how little has changed there in the last two centuries. Successive waves of traders, trappers, miners, explorers, soldiers, missionaries, settlers, steamboat pilots, road builders, and aviators have come to the Yukon, bringing economic and social changes, but the immense land "remains virtually untouched by permanent intrusions." ø
