Chunk, a 1,200-pound brown bear, has won the popular Fat Bear Week contest in Alaska's Katmai National Park. Despite a broken jaw, Chunk beat out Bear 856 in the finals. The annual online competition drew over 1.5 million votes this year, highlighting a record salmon run that allowed bears to fatten up for hibernation. The event informs the public about brown bears and their need to store fat for winter.
