Katmai National Park and Preserve in Alaska kicked off its annual Fat bear Week, with eight corpulent bears competing to pack on the pounds and earn the public's favor.

Alaska's Fat Bear Week is underway after one bear's death delayed the contest. The contestants in the 10th Fat Bear Week at Katmai National Park and Preserve were introduced on Tuesday, a day later than expected after a female bear known as Bear 402 was killed by a male bear during a fight on Monday.

Let the chunk-off begin. Voting starts Wednesday in the annual Fat Bear Week contest at Alaska’s Katmai National Park and Preserve, with viewers picking their favorite among a dozen brown bears fattened up to survive the winter.
