“Razing Appalachia,” a disturbing chronicle of the controversy over “mountaintop-removal mining” in the southern West Virginia town of Blair. Filmmaker Sasha Waters filmed in 1998, when Arch Coal Inc. of St. Louis proposed this type of mining for its Dal-Tex facility near Blair. A go-ahead would mean that affected residents would have to leave their homes in bucolic Pigeonroost Hollow; denial would mean layoffs for some 400 miners. No one Waters interviews on either side is prepared to give an inch. Blair, she says sadly, is “a town at war with itself over coal.”
