Katmai National Park's popular Fat Bear Week is set to kick off, celebrating its tenth anniversary with engaging events and contests such as the Fat Bear Junior Contest and the main competition to determine the 'fattest bear.' However, the festivities have faced setbacks due to a recent fatal bear fight, causing the bracket reveal to be postponed and the Brooks River Corridor to be closed for safety reasons. Despite these challenges, enthusiasm remains high as participants prepare for this unique wildlife conservation celebration, showcasing Alaska's chubbiest bears.
