Two generations have passed since the publication of Wilma Dykeman’s landmark environmental history, The French Broad. In Through the Mountains: The French Broad River and Time, John Ross updates that seminal book with groundbreaking new research. More than the story of a single river, Through the Mountains covers the entire watershed from its headwaters in North Carolina’s Blue Ridge and the Great Smoky Mountains to its mouth in Knoxville, Tennessee.The French Broad watershed has faced new perils and seen new discoveries since 1955, when The French Broad was published. Geologists have learned that the Great Smoky Mountains are not among the world’s oldest as previously thought; climatologists and archaeologists have traced the dramatic effects of global warming and cooling on the flora, fauna, and human habitation in the watershed; and historians have deepened our understanding of enslaved peoples once thought not to be a part of the watershed’s history. Even further, this book documents how the French Broad and its tributaries were abused by industrialists, and how citizens fought to mitigate the pollution. Through the Mountains also takes readers to notable historic places: the hidden mound just inside the gate of Biltmore where Native Americans celebrated the solstices; the once-secret radio telescope site above Rosman where NASA eavesdropped on Russian satellites; and the tiny hamlet of Gatlinburg where Phi Beta Phi opened its school for mountain women in 1912. Wilma Dykeman once asked what the river had meant to the people who lived along it. In the close of Through the Mountains, Ross reframes that question: For 14,000 years the French Broad and its tributaries have nurtured human habitation. What must we start doing now to ensure it will continue to nourish future generations? Answering this question requires a knowledge of the French Broad’s history, an understanding of its contemporary importance, and a concern for the watershed’s sustainable future. Through the Mountains fulfills these three criteria, and, in many ways, presents the larger story of America’s freshwater habitats through the incredible history of the French Broad.
