Fat Bear Week is an annual online event held by Katmai National Park and Preserve to celebrate the successful preparation of brown bears for winter hibernation. During the event, people vote for the bear that gained the most weight by eating salmon in the park. The purpose is to educate the public about bear behavior, wildlife conservation, and the importance of healthy ecosystems while engaging people in a fun and interactive way. It also raises awareness about protecting natural habitats and the role bears play in Alaska’s environment.
