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

The closet community to the park is Copper Center, which is about 200 miles northeast of Anchorage. 

The park is 13.2 million acres which the park's webpage says is the size of Switzerland, Yellowstone National Park and Yosemite National Park combined.
