Journey deep into the rainforest of southeast Alaska, where life is inseparable from the age-old rhythms of the Chilkat River. Every year, all five species of salmon return to the Chilkat, drawing the world’s largest gathering of bald eagles, insatiable grizzly bears, and fascinated tourists. The salmon also define life for two communities: The ancient Tlingit village of Klukwan and the scrappy commercial fishing town, Haines. Meanwhile, a modern-day gold rush is under way. Some locals are eager for a mining boom, while others fear that the risks to the Chilkat Watershed far outweigh short-term economic benefits.
