Grizzly bears are emerging from hibernation in the Greater Yellowstone Area, so hikers, skiers and snowshoers are advised to stay in groups of three or more, make noise on the trail and carry bear spray.
Bears begin looking for food soon after they emerge from their dens. They are attracted to elk and bison that have died during the winter.
Updated bear safety information is available on the Yellowstone bear safety website at www.nps.gov/yell/planyourvisit/bearenc.htm. The park also implements seasonal closures to reduce encounters between bears and humans in areas where elk and bison carcasses are common. A listing of these closures can be found at www.nps.gov/yell/parkmgmt/bearclosures.htm.
Yellowstone regulations require visitors to stay 100 yards from black and grizzly bears at all times. Visitors are also reminded to keep food, garbage, barbecue grills and other attractants stored in hard-sided vehicles or bear-proof food storage boxes.
Bear sightings should be reported to the nearest visitor center or ranger station as soon as possible.
