In April 2001, a U.S. government wildlife trapper named Carter Niemeyer choppered into the mountains of central Idaho to slaughter a pack of wolves whose alpha female was famed for her whiteness. He hung from the open door of the craft with a semiautomatic shotgun, the helicopter racing over the treetops. Then, in a clearing, Niemeyer caught a glimpse of her platinum fur. Among wolf lovers in Idaho, she was called Alabaster, and she was considered a marvel—most wolves are brown or black or gray. People all over the world had praised Alabaster, had written about her, had longed to see her in the flesh. Livestock ranchers in central Idaho, whose sheep and cows graze in wolf country, felt otherwise. They claimed Alabaster and her pack—known as the Whitehawks—threatened the survival of their herds, which in turn threatened the rural economy of the high country. She had to be exterminated.
