Set up camp in a fixed order: storage system first, then the three zones that storage decision forces on you, then the geometry of the hang or the placement of the container, and only then the small items — toothpaste, wrappers, the fleece you cooked in. Reverse that order and you are deciding how to store food at nine at night, in the dark, with more food than the canister holds and a tree you never actually looked at.
I have done it backward. It happened in a granite basin below a pass, in the last gray light, with a rope in one hand and nineteen pounds of food in the other. The branch looked fine from the trail. It looked fine while the bag was still on the ground. It stopped looking fine the moment the bag went up, because a bag on a rope hangs exactly as far below the branch as the rope is long, and there was nothing left to adjust. Stand where I stood for a minute and the lesson is physical: everything you needed to decide had already been decided hours earlier, at the trailhead.
Start with the container, because it decides your menu
The Interagency Grizzly Bear Committee runs a container testing program. A live bear is given a fixed window to work on the container, and the container has to still be closed when the window ends. Products that pass go on a published list. That is a checkable specification, and it is worth more than every adjective printed on the packaging.
It is also narrower than it sounds. Certification covers the shell and the closure against a bear that is actively trying. It does not mean bear-proof. There is no bear-proof. There is only how long the thing holds up and whether the bear loses interest first. A certified container left unlatched, or one with a chewed strap, is a bag.
The other thing the label won't tell you is usable volume. The number on the side is an exterior envelope. The inside is a cylinder with a rounded floor, a shoulder that tapers, and a lid assembly that eats two or three inches of height. A container sold as holding a week of food holds a week of food for a person with a modest appetite and very dense food. I measure mine by packing it, at home, on the kitchen floor, with the actual trip menu. If day one doesn't fit, the advertised number is irrelevant. I also tape the opening tool to the lid, because at 6 a.m. you will otherwise be prying at a certified closure with a rock and a spoon handle.
There is a real trade here. A tall, narrow canister gives you the most interior volume per pound, but it only rides well in a pack with a tall main compartment, and it sits high and awkward. A shorter, flatter one packs better and costs you weight per liter. Neither is wrong; they just push your packing plan in different directions. Pick the one that fits your menu and your pack, then accept the consequence: if the container holds four days and the trip is nine, the container is not your storage plan. You either plan a resupply or a cache, or you hang — and hanging means camping somewhere with hangable trees, which rules out the basin above tree line where I learned this. That is a decision made at the kitchen table, not at dusk.
The three zones are a direction, not a triangle drawn on paper
Sleep, cook, store. The hundred-yard separation you hear quoted is not a magic number; it exists so that a bear getting into one thing does not, in the same motion, arrive at another. In practice, terrain compresses it. The only flat spot is often far closer to the only good tree than you'd like. When that happens, I stop pretending I have three zones and admit I have a squeezed camp, then compensate: nothing with a smell inside the tent, the cook zone kept narrow and low, and the food moved as far along the drainage as the ground allows.
Direction matters as much as distance. Cold air drains downhill overnight, and scent rides it. If the ground tilts and water runs one way, that is roughly the path your dinner's smell is taking. Put storage downslope and off to the side of that line, not between the sleeping area and the direction a bear would naturally travel.
One more thing about the cook zone: it is defined by what you did there, not by where the stove sat. It includes the rock you ate on, the log where you set the pot lid, the patch of dirt with the spilled oil. All of it is a smell source for the next several hours.
The clothes you cooked in are part of the food
Steam gets into fleece. It gets into a beanie and the cuffs of a rain shell and the gloves you used to handle the pot. Your nose stopped registering it about twenty minutes after dinner. A bear's didn't. I change out of the cooking layer before I get into the sleeping layer and stow the cooking clothes with the food, every night, no exceptions for cold ones.
A hang is a geometry problem, not a knot problem
Read the tree before you commit to it. Live, healthy, no dead limbs overhead. A branch at least fifteen feet off the ground that extends at least six feet out from the trunk, thick enough to hold the load without folding, thin enough that a bear can't comfortably climb out along it — wrist-thick at the attachment point is the working rule. A limb that droops slightly at the tip is better than one that rises, because a bear on the branch is then working downhill. Pass on anything with a fork where a cord can wedge, and pass on a tree whose branch sits directly over the trunk, because a bear can climb up and reach out.
Here is why the simple over-the-branch hang fails so often. The cord goes over the limb, the bag ties to one end, and the other end ties to the trunk. To reach the trunk, that tail has to be long, so the bag hangs the length of the tail below the branch. A branch at fifteen feet puts your food at eight or nine. A bear standing on its hind legs reaches that without stretching.
The PCT method is a fix for exactly that. One continuous line over the branch. You attach the bag, then tie a toggle stick into the line at the point where the line reaches the trunk at a comfortable height. Raise the bag until it sits a foot or two under the limb, and the toggle jams against the branch and holds it there. Tie the tail off to the trunk wherever you like — the bag's height is now set by the toggle at the branch, not by the length of your rope. Pull the tail and the toggle releases.
Two details make it work: the cord has to be low-stretch and smooth, because a springy line lets the bag sag back down, and the toggle has to be fat enough that it can't ride over the limb. A hang is not a container. It is a delay, and it only earns that delay if the geometry is right and the tree is real.
Everything that smells goes with the food
Toothpaste. Sunscreen. Lip balm. Bug spray. Hand sanitizer. Gum. Every wrapper, including the one you've been carrying in a hip belt pocket since lunch. Trash, all of it, including the tea bag and the coffee grounds. The empty can. The fuel canister and the stove go to the cook zone at minimum, because the pot on top of them is a smell source even when the fuel isn't.
Your pack is the part people get wrong. Cook in the cook zone, then leave the pack there and carry only what you're sleeping in to the tent. The food bag comes out of the pack and goes into the container or up the line.
Plan the volume before you leave the house
Lay the whole trip's food on the floor and pack it. Dry, dense food buys you days you'd otherwise spend hanging. The first day is always the bulkiest because nothing has been opened yet, so pack for day one, not day five. Then add a buffer day, because the trip that ends early is the one where you eat the most. If you can't make it fit with the buffer, change the menu or change the storage system — those are the only two levers you actually control, and both are much easier to pull in a kitchen than in a headlamp beam.
The order I run at dusk
- Pick the three zones while there is still light, and name them out loud to whoever is with me, so nobody wanders.
- Set the container or the hang before cooking, never after. The bag goes up empty if it has to; the line is already over the limb.
- Cook and eat in the cook zone. Everything stays there.
- Seal and store the food, the trash, and the scented items together.
- Wipe the pot and stow it in the cook zone.
- Change out of the cooking layer and put it with the food.
- Take the pack to the cook zone, take only the sleeping kit to the tent.
None of this makes a bear do anything. It only removes you as the reason the bear came over in the first place. That is the whole job — and it is a sequence, not a product.
