Grizzly bears are emerging from hibernation in the greater Yellowstone area, so hikers, skiers and snowshoers should stay in groups of three of more, make noise on the trail, and carry bear spray. Bear spray is a good last line of defense, if kept handy and used according to directions, when a bear is approaching within 30 to 60 feet.
The first confirmed report of grizzly bear activity in Yellowstone National Park was February 22. Wolf biologists observed a large grizzly bear in the Nez Perce drainage.
