GRAND TETON NATIONAL PARK, Wyo. (AP) — Bears are out of hibernation at Grand Teton National Park and officials say both residents and park visitors should be alert for them.

Staff workers at Grand Teton recently received reports of a group of bears just east of the park's headquarters campus in Moose.

Typically about half of male bears are out of their dens by mid-March and females with their yearlings emerge shortly after that.

Park visitors should make noise and travel in groups of three or more. They should carry bear spray and know how to use it and always maintain at least a 100-yard distance from bears..
