your safety in grizzly bear territory

This is information for people traveling with the De Anza Outdoor Club about safety in areas frequented by grizzly bears. It is not everything you should know and it can’t be updated as fast or as well as park service information, so please consult park webpages and use the links in this page to go to park videos.

Bear attacks and other animal attacks are not common,
but there are no guarantees of your safety.

Wild animals try to stay away from people. They become aggressive if:

    they are protecting their cubs/fawns, etc.

    you surprise them

    the bear has become used to people and food rewards from people

    your dog provokes them

    you try to get close to them for a photo, pose near them for a photo, pose your child near them for a photo, try to run by them, pet them, tease them, feed them, throw rocks/stones at them, etc.

    people surround them, even if they stay the minimum 100 yards away. Always leave the bear or other wild animal an escape route.

    you see a bear, get nervous and run. Running can elicit an attack from a non-aggressive bear. A scream or sudden movement may trigger an attack. Never imitate bear sounds or make a high-pitched squeal.

    you somehow are not careful enough and a bear gets your food — and — you try to get it back.

    people fly drones around/over them, endangering themselves and others. Use of drones is illegal in National Parks. Please try to get the vehicle license number (and if possible make, model and color) / campsite number of anyone using a drone and report them to Rangers. If you have cell phone coverage, call park dispatch. The phone number for dispatch is usually in the park newspaper you receive when you enter the park. (When people fly drones around forest fires, the helicopters with firefighters and tankers with sprays to put out the fire can’t fly!)

About selfies: “The popularity of smart phone photography with its limited zoom capacity and social media sharing of selfies might explain why visitors disregard park regulations and approach wildlife more closely than when traditional camera technology was used.” is from a CDC Morbidity and Mortality Weekly Report (MMWR)

https://www.cdc.gov/mmwr/volumes/65/wr/mm6511a5.htm

Each trip member should be certain to

read current info when they enter any park we travel to

consult with rangers before hikes and bike rides

talk loudly, sing, shout, clap hands or otherwise make noise on the trail (‘bear bells’ do not work)

“When hiking, periodically yell “Hey bear!” to alert bears to your presence, especially when walking through dense vegetation/blind spots, traveling upwind, near loud streams, or on windy days. Avoid thick brush whenever possible.”
bears hear about as well as humans, so be sure to yell loudly when hiking on windy days, or near running water

never hike, run or bike alone It is best to do in groups of minimum three and trail running is discouraged as you can come too fast up on a bear. Trail running with ear buds is even more dangerous.

don’t hike at dawn, dusk, or at night “Avoid hiking at dawn, dusk, or at night: during summer, that’s when grizzly bears are most active.”

don’t expect bears to see you first “bears hibernate for approximately five months each year and have only seven months of active time to obtain all of their nutritional needs. A bear that’s feeding may not see you as quickly as you would think. Pay attention, and see the bear before it sees you…and before you surprise it.”

stay on maintained trails “Research in Yellowstone has shown that people are more likely to be attacked by a bear when hiking off-trail.”

stay away from dead animals as bears may attack to defend their food

store food properly according to current methods.

watch for, read and obey warning signs

a fed bear is a dead bear sign:

be alert “See the bear before you surprise it. Watch for fresh tracks, scat, and feeding sites (signs of digging, rolled rocks, torn up logs, ripped open ant hills).”

never approach a bear (stay at least 100 yards from bears)

do not run from a bear

NPS sign closed bear danger: NEVER ignore trail closures.

sign says warning due to bear danger area beyond this sign CLOSED to all travel

sign says trail closed bear in area, behind the sign, bears are seen

can says bear sprayTrip cost for each each Grand Teton National Park trip member includes part of the cost of bear spray, which is required for everyone to carry. Each trip member is required to attend a ranger program on safe bear spray use and watch an online video and read about bear spray before they go hiking, biking, kayaking or even walking away from developed areas. The ranger programs are offered every day at at least one Grand Teton National Park visitor center.

https://www.nps.gov/yell/learn/nature/bearspray.htm

https://www.nps.gov/yell/learn/nature/bearreact.htm

and the Yellowstone bear spray video is linked to or is at that page.

Bear spray can make a thick, wide fog:

ranger spraying bear spray

In a dozen years of club trips no one has had to use (spray) any bear spray.

says bear spray is not a deterrent, not a repellent, do not spray on clothes or on humans
Do not spray bear spray on your tent, clothes, etc. Glacier Park warns: “It” (bear spray) “is not intended to act as a repellent. Pre-sprayed objects may actually attract bears.” . . .
And yes, there was a woman in Yellowstone National Park who required (and got) medical help when she doused herself with bear spray.

Yellowstone park warns:

“Bear spray can explode if it reaches 120 degrees Fahrenheit. Don’t store it in the passenger compartment or near any heat sources.”

“Personal defense, jogger defense, law enforcement or military defense sprays may not contain the correct ingredients, or have the proper delivery system, to stop a charging bear.”

“Under no circumstances should bear spray create a false sense of security or serve as a substitute for standard safety precautions in bear county.”

Before the trip we usually have people put on their fully-loaded-for-a-long-hike large day pack / backpack, and put a can of bear spray either in a outside pocket or on a harness, and decide which kind they will want to carry.
two people with bear spray harnesses around their chests

Bear spray should be in easy reach, not hanging from the back side of your day pack or backpack,
but it does not need to be out and hand carried.

Grand Teton park would like you to watch this Backcountry Travel video before you go backpacking.
https://www.nps.gov/grte/learn/photosmultimedia/parkvid.htm

In the video there is a section on bear spray with this:

keep bear spray immediately accessible

that shows a can of bear spray tucked in the waistband of a backpack. But we advise people to consider that if they forget it is there and take their pack off quickly, for example to get at their camera for that great picture, the can could fall to the ground and even roll down a cliff side.
A can in a harness would be immediately accessible and more secure.

poster says Be prepared for bear encounters, protect bears and people

Park rules say do not approach wildlife, stay 100 yards from bears or wolves and 25 yards from other wildlife including nesting birds.

Keep the animal’s line of travel or escape route clear and move away if wildlife approaches you.

How far away is 100 yards? Picture the length of a football field without the end zones.

25 yards? picture four car lengths or six kayak lengths, or the width of an Olympic-sized pool like ours at the college.

If you have an accidental, surprise or inadvertent closer encounter with wildlife you must remove yourself to those distances, including while driving on a road.

NPS drawing of a human and various animals showing how far away we need to stay from wild animals

row of buses depicting distance to stay away from animals

Grand Canyon National Park rangers say: “Follow the rule of thumb: if you can cover the entire wild animal with your thumb you’re at a safe distance. This distance is usually 25 yards from most wildlife and 100 yards from large wildlife . . . If you are close enough to take a selfie with an animal, you are too close. ”

Parks Canada warns, along with keeping a proper distance from animals :

“If you spot the following defensive warning signals, pull back even more or leave the area:

Bears make a ‘woofing’ noise, growl and snap their jaws;
Bull elk and moose put their heads down and paw at the ground;
Cow elk flatten their ears, stare directly at you and raise their rump hair.

If you cause an animal to move, you are too close.”

This NPS photo came with this warning:
when a moose is stressed it will lay its ears back along its head and its hackles will rise.”

• Denali National park warns: “Moose are not predatory, and they will not try to eat you. Instead, they try to trample a perceived threat.”

Grizzlies are no longer rare in the Grand Tetons and can be found anywhere in the park. In Yellowstone there are 280 to 610 of them. You are more likely in Yellowstone to be hurt by a bison than a grizzly. Read before a bison charges below.

We will probably not see any grizzlies on our trips, but we should be careful nevertheless. They run faster than you. (Bears can run over 30 miles per hour, or 44 feet per second, seven times faster than the fastest human.) Grand Tetons biking has details about rare fatal encounters between bikers and grizzlies.

Rules for people at bear jams in Grand Teton park changed in 2011, after grizzly 610 twice charged people while they were standing on their car roof. Read about safety at wildlife jams

This webpage can’t be kept completely updated. Read the current Grand Teton park newspaper at:

https://www.nps.gov/grte/learn/news/newspaper.htm

or if they still are not posting it online, request a copy by mail or read a copy you can get when you enter the park.

The Grand Teton park newspaper said in summer of 2010/11/12/13/14/15/16/17 (summer 2013 and 2017 they removed some of the text, but the main points were still the same):

(And some of the park webpages had this same advice in 2020.)

Make Noise in Bear Country

Grizzly and black bears live in the park and parkway. Some of the most popular trails travel through prime bear habitat. Bears will usually move out of the way if they hear people approaching, so make noise. Don’t surprise bears! Calling out and clapping your hands at regular intervals are the best ways to make your presence known. Bear bells are not sufficient. Be particularly careful when vegetation or terrain limits line of sight. The use or portable audio devices is strongly discouraged…

Hike in groups

If possible, hike in groups of three or more people. Typically, larger groups of people make more noise and appear more formidable to bears. Keep your group together and make sure your children close at all times. Avoid hiking when bears are active, especially early in the morning, late in the day or when it is dark. Trail running is strongly discouraged; you may startle a bear.

Never Approach a Bear

2013/15/16:

All bears are wild and dangerous. Each bear will react differently and their behavior cannot be predicted.

2010/11/12:

Individual bears have their own personal space requirements that vary depending on their mood. Each bear will react differently and their behavior cannot be predicted. All bears are wild and dangerous and should be respected equally.

2016, 2017: Never leave your backpack unattended!

Never allow a bear to get human food.

If approached by a bear while eating, put food away and retreat to a safe distance.

The park newspaper said in summer of 2011/12/13/14/15/16/17: (Again, in 2017 they removed some of the text, but the main points are still the same.)

If You Encounter a Bear

Do not run; bears can easily outrun you. Running may cause an otherwise non-aggressive bear to attack.

If the bear is unaware of you or if the bear is aware of you but has not acted aggressively, slowly back away.

Do not drop your pack! This teaches bears how to obtain human food often resulting in the death of a bear.

Do not climb trees. All black bears, all grizzly cubs and some adult grizzlies can climb trees.

If a Bear Approaches or Charges You

Do not run! Most bear attacks result from surprise encounters when the bear is defending their young or defending a food source, such as a carcass. Some bears will bluff their way out of a situation by charging, then veering off or stopping abruptly. Bear experts generally recommend standing still until the bear stops and then slowly backing away.

If a bear attacks, lie on the ground completely flat on your stomach. Spread your legs slightly and clasp your hands over the back of your neck. Do not move until you are certain the bear has left the area.

In rare cases, bears have attacked at night or after stalking people. These are predatory attacks and the bear views you as food. If you are attacked at night or if you feel you have been stalked and attacked as prey, fight back. Do whatever it takes to let the bear know you are not easy prey.

If You Carry Bear Spray

Park visitor centers can demonstrate proper use of bear spray and recycle it. Come visit for more information.

Besides the above info in the park newspaper, a 2012 – 2019, (2020 webpage) also said:

Make sure you are carrying EPA approved Bear Spray as your bear deterrent, don’t depend on personal defense products to stop a charging bear.

Make sure the canister is immediately available, not in your pack.

Leave the safety clip on the trigger unless you are ready to spray an aggressive bear. The spray may accidentally discharge otherwise.

Consider the use of bear spray when affected by wind, rain, cold temperatures and age.

Follow the manufacturer’s instructions, know how to use the spray, and be aware of its limitations, including the expiration date

If you use the spray to stop a bear, leave the area immediately.

Bear spray is NOT a repellant! Do not spray it on people, tents or backpacks.

Do NOT store your bear spray in a vehicle. It may explode.

Under no circumstances should bear spray create a false sense of security or serve as a substitute for standard safety precautions in bear county.

NPS chart depicting bear -cause injuries and fatalities in Yellowstone National park

“Bear-Caused Human Fatalities
During the 145-year (1872-2015) history of Yellowstone National Park, eight people have been killed by bears in the park.
More people in the park have died from drowning, burns (after falling into thermal pools), and suicide than have been killed by bears.
To put it in perspective, the probability of being killed by a bear in the park (8 incidents) is only slightly higher than the probability of
being killed by a falling tree (6 incidents),
in an avalanche (6 incidents),
or being struck and killed by lightning (5 incidents).”

What do Grizzly bears sound like? Griz vocalizations (“Grizzly bears sometimes vocalize when agitated or nervous. These sounds of huffing, jaw-popping (heard at :35 and :57 seconds in), and low growls are warnings that you’re too close.”) :

https://www.nps.gov/yell/learn/photosmultimedia/grizzlyvocalizations.htm

two bears facing each other in a river

The NPS notes with the photo above were: “The position of a bear’s ears often indicates its level of stress. The bear on the left lowered his ears against his skull when the larger and more dominant bear on the right approached. This was likely a sign of defensiveness. Note that the more dominant bear’s ears are still upright. Bears will lower their ears when they react defensively around people too. . .

. . . Look and Listen for Signs of Stress: Vocalizations like woofing, huffing, and jaw popping are almost always indications of stress. If you hear a bear vocalizing then the bear is most likely warning you. The position of a bear’s ears also communicates information. Ears that are pointed forward usually indicate a sense of curiosity or dominance. Ears that are flattened back on a bear’s head is indicative of stress and/or defensiveness.”

______________________________________________

Denali Park answers the question: Can grizzly bears climb trees?

“Young grizzlies can climb trees as effectively as black bears, but adult grizzly bears have more difficulty. Most grizzlies can climb a tree if it has ladder-like branches, but their weight and claw structure prevents them from climbing as efficiently as black bears. Three of the 23 documented bear-induced human injuries in Denali involved grizzlies pulling humans out of trees so don’t try to climb a tree to avoid any bear.”

NPS standing grizzly:

When a bear stands in the movies it is often growling and about to charge, but this is not usual behavior.

Bears are nearsighted. When a real bear in the wilds stands, it often is trying to better smell what it thinks it sees, or see what it thinks it smells.

Food and Bears

Proper food and garbage storage is important to the safety and well-being of both bears and humans. Leaving food where bears can get it is not only illegal, but extremely dangerous for both bears and people. Bears are always searching for food and have an acute sense of smell. If you leave food out unattended, you are inviting a bear to your camp. A bear that eats human food or garbage – even once – may become conditioned to human food and garbage, or reliant on this easy source of food. These bears often become increasingly aggressive and may damage property, threaten, injure, even kill people in their attempts to obtain food. If a bear becomes conditioned to human food and garbage, it will likely have to be destroyed to protect human safety.

From the park newspaper, 2019:

“Keep a Clean Camp

Improperly stored or unattended food will be confiscated and you may be fined.

Treat odorous products such as soap, toothpaste, fuel products, suntan lotion, candles, and bug repellent in the same manner as food.

Food storage regulations in the Tetons and Yellowstone (and Glacier) are not as stringent as those we are used to in Yosemite, but do include the use of bear-proof lockers in campsites and trailheads.

Food, garbage, and all items used for storing, preparing, or eating food must be properly stored whenever they are not being transported, prepared or eaten, both day and night. (This includes trash and recyclables; water bottles; stoves and grills; dishes, utensils and washbasins; pet food and bowls.)

Check the material given you when you enter the park or ask a Ranger for the most current rules on food storage.

Most Outdoor Club regular travelers to Yosemite would be more likely to follow the Yosemite rules of no food, toiletries or food-like items in cars even if the parks in grizzly bear areas say that it is still okay to store items hidden in a closed, locked vehicle with windows rolled up. We don’t want to be the model when the first Grand Teton grizzly or black bear figures out how to open car doors like Yosemite black bears have done for years and years. See bears for details, including things that don’t smell like food but look like a food container to a bear who sees it through your vehicle window.

Glacier National Park also noted, in the section on if you surprise a bear, “Use peripheral vision. Bears may interpret direct eye contact as threatening.”

Please, no trail running in Grand Teton National park: “Trail running is strongly discouraged; you may startle a bear.” Glacier National Park: “Trail running is discouraged as there have been an increasing number of injuries and fatalities due to runners surprising bears at close range.”

Don’t bike or jog/run by yourself, it is safer to bike in groups since there are very large, potentially dangerous and unpredictable animals potentially everywhere.

Data suggest that rates of sudden encounters with bears are much higher among cyclists than hikers.Grand Tetons biking includes statistics about cyclist encounters with grizzly bears.

Most animal attacks are caused by people getting too close to these WILD animals, see also the bears, elk, moose or bison section of: fatal, near fatal or close call incidents/accidents in camping, backpacking, climbing and mountaineering

You don’t need to be afraid if you are lucky enough to hear wolves howling or see wolves. In Rocky Mountain Natural History, by Daniel Mathews, we read: “wolves don’t hurt people. I’m not saying never ever not even once, but it’s so rare, we could have fun listing housepets and house hold objects that pose more danger. Um, pit bulls, bobby pins…”

NPS photo of a bison by Dan Ng: bison looking towards the photographer sign danger do not approach wildlife: Yellowstone warning sign do not approach bison: NPS photo Chevy after collision with a bison: NPS photo Chevy with front end damage after collision with a bison.

From a Yellowstone study:

“apparently unusual actions or warning activities by bison just before they charged. Bison ‘false-charged’ in only one case, stamped feet in one case, and snorted in another case. In two cases, the bison shook its head before charging. Rolling on the ground (wallowing) immediately preceded two charges. In three cases, bison butted trees just before they charged toward humans. Tail-raising is commonly considered a sign that bison are agitated. We found that snorting, head shaking, foot-stomping, tree-thrashing, or wallowing may also be warning signals that a bison is about to charge.”

“Despite their size and seemingly slow moving habits, bison are surprisingly agile and can be quick to react.”

(Bison can run three times faster than humans can sprint. Bison can spin around faster than a horse. Don’t count on a bison giving warning. Stay a minimum 75 feet (or more) away from all large animals so you won’t contribute to further studies.)

In this photo of a bison about to cross a road, note the size of the bison in comparison to the people and their cars. (Bison are 10-12 feet long, 5-6 feet tall at the shoulder, males weigh up to 2,000 pounds – about the same weight as a Scion XB or Volkswagen Beetle.) If the bison decided to change his direction of travel, or move quickly, people could have been injured. Children trying to stand/hide behind an open car door could be caught between the door and the vehicle if the bison moved quickly and charged the door.

Mountain Lion

The NPS warns: “While mountain lions generally prefer to avoid people, aggressive behavior can be caused by a number of factors including: a mother protecting kittens, a juvenile cat learning what is and is not prey, an older, injured, or ill cat who is stressed for food and approaching non-typical targets in desperation, or a curious cat whose ambush instincts are triggered by human behavior” (such as running).

Yosemite National Park says: “Watch children closely and never let them run ahead or lag behind on the trail. Talk to children about lions and teach them what to do if they meet one. Never approach a mountain lion. Don’t run, but hold your ground or back away slowly. Face the lion and stand upright. Do all you can to appear larger. Grab a stick. Raise your arms. If you have small children with you, pick them up. If the lion behaves aggressively, wave your arms, shout and throw objects at it. The goal is to convince it that you are not prey and may be dangerous yourself. If attacked, fight back!”
