Timothy Treadwell

Anniversaries are being marked of the death of Timothy Treadwell, the American bear enthusiast who lived among grizzlies in Alaska's Katmai National Park for over a decade. On this day in 2003, Treadwell and his girlfriend Amie Huguenard were killed and partially eaten by a grizzly at their camp. The case remains one of the most discussed human-wildlife encounters, drawing debate over whether living unprotected among wild bears was ever sustainable.
