The incident marked the first fatal bear attack at Wrangell-St. Elias National Park and Preserve.

The hunter – who was on a 10-day moose hunt with a friend – was mauled on September 20, according to the National Park Service. Due to the pending investigation into the incident, the deceased hunter’s identity has yet to be revealed. Both hunters were near the Chisana River drainage in southeast Alaska at the the time of the attack. After the mauling, NPS warned on Tuesday: “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.”

The incident “is the first known bear mauling fatality recorded” in the area since the park was founded in 1980.

The Alaska Department of Fish and Game warns that if hunters encounter bears that do notice them, they should ready their deterrent, stay calm, look big, and don’t run.
