Night of the Grizzlies is a book, published in 1969, by author Jack Olsen, which details events of August 13, 1967,[1] when two young women were separately attacked in Glacier National Park, Montana by grizzly bears. Both women, Julie Helgeson, 19, of Albert Lea, Minnesota and Michele Koons, 19, of San Diego, California died of their injuries.[2] Olsen's book investigates the potential causes of the incidents[3], in an area where no grizzly attacks had previously been recorded.[4]
An unrelated but similarly named movie had been released in April 1966 before the above-referenced attacks.
