Alaska's Katmai National Park to Host 11th Annual Fat Bear Week Celebrating the Bulkiest Brown Bears

Alaska’s Katmai National Park to Host 11th Annual Fat Bear Week Celebrating the Bulkiest Brown Bears

Katmai National Park, Alaska – The applauded showdown of Alaskan bears, known as Fat Bear Week, is returning for its 11th annual event this September at Katmai National Park. Running from September 23 to 30, this unique competition celebrates the transformative journey of the park’s brown bears as they pack on pounds preparing for winter hibernation.

Though the showdown has no prize for the winner, it has cultivated a passionate community of fans who actively vote online to crown the bulkiest, chunkiest bruin. The event will livestream the fierce competition among a dozen hefty bears, showcasing nature’s remarkable spectacle.

The Fierce Battle for the Title of Heaviest Bear

Every year, Alaskan brown bears at Katmai ramp up their weight gain, reaching weights up to 1,200 pounds by November. These massive creatures accumulate roughly four pounds daily during the pre-hibernation season, fueled largely by the abundant sockeye salmon in the Brooks River. Here, eight strategically placed cameras, including an underwater salmon camera, capture the bears’ activity without disrupting their natural behaviors.

Voting takes place online with open windows daily from noon to 9 p.m., allowing fans worldwide to weigh in. The observational nature of the event means scientists estimate each bear’s weight without disturbing their diets or habitat, maintaining the contest’s wild authenticity.

“From tubby titans to gargantuan gluttons, get ready to cheer for the heftiest bears in Katmai National Park and Preserve’s Brooks River!” said park officials in a social media announcement.

The History and Evolution of Fat Bear Week

Fat Bear Week was created in 2014 by Mike Fitz, a retired ranger of Katmai National Park. Initially planned as a one-day event, it quickly blossomed into a weeklong celebration, gaining increasing popularity and even inspiring the creation of Fat Bear Junior, a cub-focused contest held from September 18 to 19 this year.

The 2024 bracket announcement faced a delay caused by a fatal altercation between a scheduled participant and another bear – an unusual but stark reminder of the wild setting of the event.

Last year’s champion was the massive bear known as Grazer 128, who was notably also caring for a cub during the competition, overpowering contender “32 Chunk” decisively.
