COPPER CENTER, Alaska (AP) — A hunter has been killed by a grizzly bear in Alaska’s Wrangell-St. Elias National Park and Preserve.

It’s the first-known grizzly attack death in the nation’s largest national park.

Park officials said in a statement that the hunter was killed Sunday while on a 10-day moose hunt with a friend.

It is the first deadly encounter with a grizzly bear since the park was established 40 years ago.

The closest community to the park is Copper Center, about 200 miles northeast of Anchorage. The park is over 13 million acres, or roughly the size of Switzerland, Yellowstone National Park and Yosemite National Park combined.
