What it takes to win 'Fat Bear Week'

Every autumn, Katmai National Park and Preserve in Alaska hosts 'Fat Bear Week', an annual tournament celebrating the success of the bears at the park’s Brooks River.

This year’s newcomer, 806 Jr, is a chubby brown bear cub, which “has the fastest growth rate of any age class of bear,” said Mike Fitz, a former park ranger at Katmai National Park who founded the competition in 2014.
