using a bear resistant food storage container

Most parks/wilderness areas now require backcountry overnighters to use bear resistant food storage canisters (bear cans) instead of hanging food from trees. This can be because of bears, or some places along the coast especially, raccoons. Where hanging food is allowed,you can waste a lot of time trying to find just the right tree to hang things properly and you risk loosing your food if you do it wrong.

At some designated backcountry camping areas there are big metal bear boxes, but they don’t always have room in them for all the food/toiletries of the the potential users, so backpack sized food storage containers are a wise thing to use for all backcountry travel.

Check in advance of purchasing to see which brands of hard plastic models are okay where you go. Some bear resistant food containers made of Kevlar, fabric and/or fabric aluminum have been invented, but are not allowed at many parks.

Most parks that require them also rent them, some with a fee, many for free.

Note that they call these bear ‘resistant’ containers. It is especially not ‘bear proof’ if it is not closed and latched or latched improperly, or if you are not near it/your food and watchful when you have things out of it.

Everything you eat, including in seemingly strong packaging, such as canned tuna, must be in the container.

All toiletries (lotion, lip products, sunscreen, soap (body and dish soap), insect repellent, deodorant, feminine products, and medications) must be stored in the containers. When you re-pack sunscreen into a small container, please don’t skimp on the amount you pack.

These rules apply 24 hours a day, (except when you are actually using/cooking items) not just overnight. You might think you can leave some of the skin care items out handy in your pack all day, but if you forget and set the pack down while you take a restroom break, for example, various mammals can chew into your pack in seconds and some Ravens know how to get packs open. If all snacks are kept in the containers except when you are actually eating them you won’t forget to check all your pack/pants/shorts/jacket pockets and end up with food in your tent overnight, and your clothes won’t smell of the food. When we dayhike in some bear areas we keep the lunches/toiletries in a bear resistant container for the same reasons.

From The Yosemite Bear Facts (July 13 – July 19, 2003)

“Several bears continue to obtain food from backpackers in the Little Yosemite Valley area, including the Sunrise Creek and Moraine Dome area. One bear has learned to snatch backpacks containing food from unsuspecting hikers who have left their packs on the ground while pumping water or using the restroom. Another bear has learned to intimidate campers, snatching their open bear canisters if they show signs of backing down. It is important for backpackers and hikers to always be aware of their surroundings and to watch for sneaky bears.”

When we travel by canoe/kayak to backountry sites with a designated big metal food storage locker for each site, we always bring at least one of the backpack sized containers so we can have snacks and/or one meal’s worth of food at the beach. Then we can easily lock everything up if a swim or picture taking opportunity presents itself without having to carry everything back to the food storage locker.

Overnight, many locations recommend you keep the containers 100 feet downwind from your campsite sleeping area, and also recommend that you cook at least 100 feet downwind if there is no designated ‘campsite’. Other places they want you to keep your canister(s) within sound of a bear trying overnight to get into it/them, with clean pans stacked on top of it to make noise and wake you up so you can yell at the bear.

If you put some reflective tape/paint on the outside you can spot it more easily with a flashlight (electric torch) overnight and identify whose canister is whose.

If you store it near a slope/near a cliff it may roll away. Stored near a waterway it can end up going downstream when a bear inspects it. (And they will inspect it, and even drool on it.)

Tying a rope around it to make it easier to attach to your backpack also gives the bear a way to grip it with its teeth and walk away with it. An insulating cover can also make it easy for a bear to get away with it.

canister:

The De Anza College Outdoor Club uses Backpackers’ Cache bear resistant container, by Garcia Machine.

It is 8.8″ in diameter by 12″ long, and it fits inside most backpacks.

If packed efficiently (see advice on this below), it holds several days worth of food.

You open it by rotating the two latches with a coin, and pushing down on a button to remove the lid. (Don’t count on keeping track of where the one coin you use is, (and don’t count on not dropping it down between some rocks where you can’t retrieve it), store a spare quarter or two among your gear or sew/tie a washer about the size of a quarter on a cord to your pack.)

As of the info with the first one we bought in 2001 they recommend: “Keep it closed with both latches locked. Be prepared for uninvited guests. Keep it away from excessive heat, don’t use it as a stove stand. Store it away from the sleeping area. Do not attempt to retrieve a it while a bear is actively interested in it. A bear will fight for food. Let the bear paw, chew and kick the canister. He will lose interest in it and leave of his own free will.”

The club does not own enough of these for everyone’s needs on a large trip, but enough that each person or couple can have one in advance of a trip to plan food packing. Then they can rent others in the park. The canisters can be rented at many locations in many parks that require them, such as entrance area information stations and retail stores.

In a big group we keep track of which container is which by putting colored tape or stickers on them. I have one with a sticker that says “Protected By ELECTRONIC Security System.” A Ranger didn’t get the joke, do you think a bear will?

You can fit more food in it if you remove excess packaging and cut out only the instructions and pack them with the food.

Don’t think you will remember how to make a meal without the instructions!

Pack toiletries into smaller containers. Cut a slice of deodorant off the stick and put it in a baggie. Use an almost worn out bar of soap. Squeeze an appropriate amount of toothpaste into a baggie. And again, when you re-pack sunscreen into a small container, please don’t skimp on the amount you pack.

(The photo above from the Grand Teton webpage might seem to imply that you should empty canned tuna into some other container (zip-lock bag?) but think through whether you will be able to protect that wetness from leaking and whether the tuna will stay healthly to eat when opened and not refrigerated.)

Think through each meal. Pre-measure each ingredient. (If you bring a entire huge box of something you will not actually eat all of, you could end up with leftover spoiling food you think you want to bury rather than pack out.)

A meal based on tortillas takes less space than one based on big sandwich rolls. Likewise spaghetti takes less space than macaroni.

Leave instant soup and others in their original envelopes but don’t bring the boxes.

It will be easier to cook less if you decide you want less if you pre-measure instant potatoes into serving-size baggies instead of full-meal-sized portions (and put instructions with them).

If you use pre-made freeze dried meals they often come in inflated packages. For a short trip you might pin-prick them just before packing to let extra air out.

If each person in a large group brings ‘extra’ for everyone else, you carry too much weight, so communicate with each other on that subject.

Double bag at least the powdered items, if not everything, in good-quality plastic bags, not the giveaway ones from your grocer’s produce section.

Pack a complete list of what you brought so you don’t forget anything. Specifically list major ingredients like margarine/butter. The head cook and food packer may have planned two sticks (8 tablespoons) as ingredients in various main dishes and only one/half stick for ‘extra’ so it’s important that other cooks know how much to not use on popcorn.

One exception to the no-boxes-rule could be one for crackers to keep them from crumbling into bits.

Canned tuna in oil gives you more calories for the weight than canned tuna in water.

You might think you can use one less container or bring more stuff if you don’t pack the first night’s meal in the container. But if you arrive quite late and/or just can’t fathom cooking and eating any of your planned dinners, you can be left with more food that fits.

You can have great backpacking meals with no-cook foods. See GORP and hiking snacks

NPS bear tracks: bearlogo: from the Keep Bears Wild program NPS bear tracks:

Incidents of bears obtaining human food in popular wilderness areas often occur at higher rates than elsewhere in parks. Wilderness areas exposures to human food may also cause bears to subsequently search for human food
in developed areas.

Think you can outwit the bears by using some other method or other bear resistant container design than the approved containers? If you try and fail it could mean the bear will keep on trying to get human food and may have to be put to death. Zoos don’t want them and when the park tries to relocate them they mostly come back to where they found easy human food sources, or die trying to.

Some places people are even warned to NOT stop and eat:

a fed bear is a dead bear sign:

You need the containers at high altitude. Bears do not find natural food at high altitude, but having learned to get food from backpackers they now frequently roam there.

Bears are very smart animals. The ‘bear proof’ garbage bins have been redesigned many times by the park service. Bears have been used in circuses around the world because of their brains and gymnastic abilities. In backpacking areas some have been known to keep up the circus tradition by climbing on limbs above a suspended food bag and leaping to snag it with their claws on the way to the ground. Rock climbers report that bears pulled up food bags they hung over sheer rock cliffs. Bears don’t mind water and have swum out to a raft people thought they could hide food on.

At the top of the stairs at the beginning of the portage trail from Leigh Lake to String Lake in Grand Teton park, and at the end of the portage trail as well, there’s a bear box (standard campsite metal footlocker style) with a sign on it reminding people to put all their food in it while they carry their canoe/kayak down the trail instead of leaving food sitting out unprotected.

bear box portage store food here:

On a trip a few years back in Grand Teton the rangers were prohibiting picnics in one popular area because a mom bear was teaching her cub to bluff charge picnickers to scare them away from their food.

Bears can get into locked rooftop car storage pods.

~Rangers do walk through backpack sites to check on things regularly; they can give out hefty fines for improper food storage, waste disposal or fires. They have even made people
without permits or with violations walk back out.

FAQ: Can I use repellents, etc. to keep bears or coyotes or … out of camp?

NO.

A bear may enter your campsite day or night, even in the presence of many people, large dog(s), a big campfire or lots of lights. Running your vehicle engine or generator, playing loud music, trying various ‘repellents’ (mothballs, an open bleach container, dog or cat in-the-garden repellent, etc.) will not work.
