(JACKSON, WY) – Grand Teton National Park is revising its rules for its annual fall elk hunt. Areas where grizzly bear encounters have been reported will be closed. The park will also limit the amount of ammunition that hunters can carry in order to better encourage hunters to make well-placed shots. They say wounded elk attract grizzly bears, which could lead to more encounters between grizzlies and humans. An elk hunter was mauled in the park in 2011, and hunters shot and killed a charging grizzly in the park last fall.
