"The Yukon river is 2,000 miles long, the longest stretch of free-flowing river in the United States. In this riveting examination of one of the last wild places on earth, Adam Weymouth canoes along the river's length, from Canada's Yukon Territory, through Alaska, to the Bering Sea. The result is a book that shows how even the most remote wilderness is affected by the same forces reshaping the rest of the planet."--Dust jacket.
