The death of a grizzly bear in Grand Teton National Park on Thanksgiving Day of 2012 has triggered calls for ending the park's annual elk hunt. A hunting party shot the grizzly after the hunters said the bear charged them. Park Superintendent Mary Gibson Scott calls the bear's death a travesty. It's the first hunting-related grizzly death in the park. But Scott says her agency, the National Park Service, can't just end the hunt. Rebecca Huntington has more.
