Black Diamonds charts the escalating drama in Appalachia over the alarming increase in large mountaintop coal mines. These mammoth operations have covered 1200 miles of headwater streams with mining waste; demolished thousands of acres of hardwood forest; and flattened hundred of Appalachian mountain peaks. Citizen testimony and visual documentation interwoven with the perspectives of government officials, activists, and scientists create a riveting portrait of an American region fighting for its life--caught between the grinding wheels of the national appetite for cheap energy and an enduring sense of Appalachian culture, pride, and natural beauty.
