Fat Bear Week 2024 has officially returned, and the salmon of Brooks River are swimming for their lives. This annual celebration at Katmai National Park in Alaska pits the park's brown bears against each other in a single-elimination tournament to crown the fattest bear. Starting September 22 and running through September 29, the event invites the public to vote online for the bear that has packed on the most pounds before winter hibernation.
What is Fat Bear Week?
Fat Bear Week began in 2014 as Fat Bear Tuesday, a humble Facebook bracket that quickly went viral. Now in its 12th year, it has become a global phenomenon, drawing over 1.7 million votes from more than 100 countries last year. The tournament showcases the impressive weight gain of Katmai's brown bears as they feast on spawning salmon in the Brooks River. It's a celebration of nature's preparation for winter and a way for people worldwide to connect with this remote Alaskan wilderness.
How Does the Tournament Work?
The bracket features 12 bears, each paired in head-to-head matchups. Voters compare before-and-after photos—one from early summer and one from fall—and choose the bear they believe has been most successful at packing on fat. The bear with the most votes advances to the next round until a champion is crowned. This year's bracket was released on Friday, giving enthusiasts the weekend to study the competitors.
Meet the 2024 Competitors
This year's lineup includes a mix of seasoned veterans and newcomers. Notably, there are more cubs at Brooks Camp than have been seen in a long time, according to park superintendent Mark Sturm. "A new generation of fat bears is taking shape, and they're off to a strong start," he said. Defending champion Bear 32, nicknamed "Chunk," is back to defend his title, but he faces stiff competition from other hefty hopefuls like Bear 480, known as "Otis," a four-time champion.
| Bear | Nickname | Notable Fact |
|---|---|---|
| 32 | Chunk | 2023 Champion |
| 480 | Otis | 4-time Champion |
| 747 | Colbert | Large male, fan favorite |
| 128 | Grazer | Productive mother |
Why Fat Bear Week Matters
Beyond the fun and competition, Fat Bear Week highlights the importance of healthy ecosystems. The bears' success depends on a robust salmon run, which in turn indicates a thriving river system. Katmai National Park protects over 4 million acres of wilderness, providing a sanctuary for these bears and countless other species. The event also fosters a sense of community among wildlife lovers, many of whom may never visit Alaska in person.
