Immediate Actions When You See a Brown Bear
Stay calm and do not run. Identify yourself as human by speaking in a calm, firm voice. Move slowly sideways to avoid tripping and to appear less threatening. Keep your group together and give the bear a clear escape route. If the bear is not approaching, back away slowly while watching it. If the bear stands up, it is usually trying to get a better view or smell, not preparing to charge. According to the U.S. Fish and Wildlife Service, most encounters end without conflict if you remain non-threatening and avoid direct eye contact, which can be interpreted as a challenge. Keep your backpack on to protect your back if a strike occurs.
Use bear spray only if the bear is within 30 feet and moving toward you. Bear spray is a pressurized capsaicin-based deterrent that creates a large cloud affecting the bear's eyes, nose, and lungs. The EPA classifies bear spray as a pesticide, and real-world data from studies published in the Journal of Wildlife Management show it is effective in stopping aggressive behavior in over 90 percent of close-range encounters. Brands like Counter Assault and UDAP are widely cited in safety guides. Check the expiration date before your trip, as expired spray may fail to deploy properly.
Bear Behavior and How to Respond
Defensive vs. Predatory Behavior
A defensive bear is protecting food, cubs, or space. Signs include huffing, jaw popping, swatting the ground, and bluff charges. In this case, stand your ground, speak firmly, and use bear spray if the bear closes distance. Do not drop your pack, as it provides protection. A predatory bear moves silently, stalks, and ignores attempts to appear large or loud. This is rare but requires a different response. If a brown bear continues to approach and makes contact, play dead by lying flat on your stomach, clasping your hands behind your neck, and spreading your legs to make it harder to flip you over. Wait until the bear leaves the area before moving.
Grizzly vs. Black Bear Identification
Grizzly bears are a subspecies of brown bear with a pronounced shoulder hump, a concave or "dished" face profile, and long, curved claws. Black bears have a straight face profile, no shoulder hump, and shorter, curved claws. Size alone is not a reliable identifier, as color varies widely among both species. The Interagency Grizzly Bear Committee provides range maps and identification guides used by land managers in the Greater Yellowstone and Northern Continental Divide ecosystems.
Prevention and Preparedness Before Entering Bear Country
Store Food and Scented Items Properly
Use bear-resistant containers or hang food at least 10 feet high and 4 feet from any trunk or pole. Cook and eat at least 100 yards from your sleeping area. Pack out all trash and food scraps. The National Park Service requires bear canisters in many backcountry areas, and some trailheads rent them. Companies like BearVault and Garcia produce containers tested to withstand grizzly attempts to access contents.
Carry and Know How to Use Bear Spray
Carry EPA-registered bear spray with a minimum of 7.9 ounces of spray and a range of at least 20 feet. Practice pulling the safety clip and aim slightly downward to create a wall of spray between you and the bear. The U.S. Fish and Wildlife Service recommends keeping spray accessible on a chest holster or hip belt, not buried in your pack. Check local regulations before flying with bear spray, as the Transportation Security Administration allows bear spray in checked baggage only if the canister is 18 ounces or less and you notify the airline.
