The Brooks Range is home to both black bears and grizzly bears. Black bears primarily inhabit the forested areas of the park, grizzly bears live mainly on the open tundra, but may be encountered in all areas of the park. The bears of the Brooks Range are wild creatures, free to behave as they wish. If annoyed or surprised, these solitary animals can be dangerous to intruders.
Bears are active both day and night and can be found anywhere.
Watch for their tracks and scat. Avoid surprising bears. They may perceive you as a threat if you startle them. Sing, shout, or make other loud noises as you walk to warn bears of your presence. Be especially careful in dense brush, where visibility is low, and along rivers, where bears cannot hear you over the noise of the water.
