Caribou have been on the landscape for more than 400,000 years. For roughly the past 12,000 years, they have been hunted by humans — first the paleo-Indians, now the First Nations’ cultures along with many other Alaskans.

Bear attacks are rare in the park, but this incident shows that bear country travel always entails risk.
