At a huge national park that is the same size as Yellowstone National Park, Yosemite National Park, and Switzerland combined, a grizzly bear mauled and killed a hunter on an Alaskan hunting trip, in a first-of-its-kind attack at the park.

The mauling took place on Sept. 20 in the Wrangell-St. Elias National Park and Preserve, a 13.2-million-acre area located in southeast Alaska, while the hunter was on a 10-day moose hunt with a friend at the time of the mauling. 

The exact injuries suffered by the deceased were not disclosed, however, we do know that no one else was injured in the attack. The identity of the mauled hunter is being withheld pending investigation. 

“Visitors are encouraged to be Bear Aware when traveling in the backcountry and take precautions such as carrying bear spray and using Bear Resistant Food Containers,” said NPS in a statement following the incident. 

The park was established 40 years ago in 1980, according to the United States National Park Service.
