This new report on the death of Richard White in Denali National Park in August 2012 shows some of the chilling photos he shot in the final moments of his life (1:58). White, a 49-year-old scientist from San Diego, California, was an experienced hiker who had been to Denali before. He had sat through the mandatory bear safety course given to everyone who gets a backcountry hiking permit, but ignored it's most basic lesson - he had been filming the bear for nearly 8 minutes before it noticed him, and was only 40 yards away when it charged. The bear was later shot by park rangers. This was the first bear mauling fatality in the park's history.
