The exciting high points of this story of Alaska since the American acquisition are brought vividly to life: the gold rush either over the forbidding Chilkoot Pass or up the Yukon to Dawson, Canada, then later to the Golden Beaches of Nome; the tremendous growth and exploitation of the salmon industry; the discovery of oil and its social and economic consequences; the difficult construction over permafrost of the Alcan Highway, making possible the defense of teh territory in World War II.
