The annual Fat Bear Week competition, hosted by Katmai National Park in Alaska, is set to return for its 13th year from September 22 to 29. This popular online event allows fans to vote for the brown bear that has gained the most weight in preparation for winter hibernation.
Participants can compare photos of the bears taken in early and late summer to determine which ursine has packed on the most pounds. Last year's competition saw a significant turnout, with over 1.7 million votes cast from more than 100 countries to crown the champion.
