The Columbia and its tributaries are rivers of conflict. Amid pitched battles over the economy, the environment, and breaching dams on the lower Snake River, the salmon that have always quickened these rivers are disappearing. On a warm day in late May, Mike Barenti entered the heart of this conflict when he slid a whitewater kayak into the headwaters of central Idaho's Salmon River and started paddling toward the Pacific Ocean. This account of his two-month, nine-hundred-mile solo journey into the world of the Columbia Basin plunges us into the adventure of navigating these troubled waterways. nbsp; Kayaking Alone is a narrative of man and nature, one-on-one, but also of man and nature writ large. In the stories of the river guides and rangers, biologists and ranchers, American Indians and dam workers he meets along the way, the rich and complicated life of the river emerges in a striking, often painfully clear panorama. Through his journey, the ecology, history, and politics of Pacific salmon unfold in fascinating detail, and with this firsthand knowledge and experience the reader gains a new and personal sense of the nature that unites and divides us.
