This has a real grab. On the night of August 12, 1967, after over half a century of peaceful coexistence with man, two grizzlies, some twenty miles apart, went berserk and killed two nineteen-year-old girls in Glacier Park. The book takes you right through the summer's events in which stupidity was compounded by carelessness in a combination of circumstances that made, as the author points out, the tragedy inevitable. For example, an immense, scrawny bear was allowed to raise havoc among campers for at least three months while the complaints that poured into the Park Rangers' office were ignored or forgotten. Meanwhile a chalet manager was making nice profits by illegally feeding a pack of bears as a tourist attraction. . . this close to an outdoor camping site where one victim would eventually be found. The events are very carefully constructed--the author has done a thorough job of interviewing and it's the kind of horror story you can't put down.
