Fat Bear Week- an annual celebration of success. All bears are winners but only one true champion will emerge. Held over the course of seven days and concluding on the Fat Bear Tuesday, people chose which bear to crown in this March-Madness style bracket where bears are pitted against each other for your vote.

Why fat matters

From its humble beginnings as Fat Bear Tuesday in 2014 to nearly 800,000 votes cast last year in 2021, celebrating fat bears and Katmai's healthy ecosystem has since become a tradition. For bears, fat equals survival. Each winter, bears enter the den where they will not eat or drink until they emerge in spring. During this time, they may lose up to one-third of their body weight as they rely solely on their fat reserves. Survival depends on eating a year's worth of food in six months.

At Katmai, bears are drawn to the large number of salmon readily available from roughly late June through September. Salmon have long since been the lifeblood of the area, supporting Katmai's people, bears and other animals. Fat bears exemplify the richness of this area, a wild region that is home to more brown bears than people and the largest, healthiest runs of sockeye salmon left on the planet.

How it works

Rangers create a March-Madness style bracket pitting individual bears against each other. The public then votes to see who will advance each round. Voting takes place over several days on www.fatbearweek.org. People may vote using any criteria they see fit. In the end, one bear will reign supreme.

2022 Fat Bear Week

This year, Fat Bear Week starts on October 5 and concludes on Fat Bear Tuesday, October 11. In addition to voting during this week-long tournament, there will be a series of online chats on explore.org featuring Mike Fitz, explore.org's resident naturalist, and rangers from Katmai. These chats focus on both the individual bears and Katmai's healthy ecosystem. Throughout the season, you can also tune in to the explore.org bear cams, which offer unprecedented access to the lives of the bears of Brooks River. There are also special live events on a variety of topics hosted weekly throughout the season.
