How we verify bear canister rules

Every verdict on this site is one of six statuses. Each comes from one official rule, a model list or standard, and a date we checked it.

The six statuses

Legal

The canister meets the area's named list or written standard, based on the official source we cite.

What we do

  1. We read the land manager's own page, then record the rule in plain words, the date we read it, the date the page says it was updated, and the link.
  2. We record which model list or standard the area uses. Some areas name their own list, some follow the IGBC certification, some say only "hard-sided".
  3. We match each canister to that list or standard, and set one of the six statuses. Where the name on a list does not match a product exactly, the status is VERIFY or LIKELY_LEGAL, not LEGAL.
  4. We flag anything that weakens the answer: an order that ends soon, a source page with an old or missing date, or a rule we could only partly confirm.

Rule types

LIST SIBBG
This area accepts only containers that appear on a named list (the SIBBG-derived list as published by NPS). A canister missing from the list is not accepted, even if another agency or lab has certified it.
LIST OLYMPIC
Olympic National Park keeps its own list of Approved Food Storage Containers. Only containers on that list are permitted; IGBC certification alone does not qualify a model.
IGBC
This area accepts containers certified by the Interagency Grizzly Bear Committee (IGBC). Check the IGBC certified products list, not the brand's marketing, to see whether a model qualifies.
IGBC HARD
This area accepts IGBC-certified hard-sided containers. Soft-sided bags do not qualify here, even when they carry IGBC certification.
IGBC PLUS NAMED
This park accepts IGBC-approved containers and also names a few additional canisters directly (Garcia, Wild Ideas and Purple Mountain). Its page is old, so confirm before relying on either list.
GENERIC HARD
The written rule asks for a hard-sided, solid or non-pliable container but names no approved list. A commercially made hard canister that is on a recognised list should meet the standard; a soft bag does not.
GENERIC BEARPROOF
The written rule asks for a bear-resistant container (or similar wording) but names no approved list. Hard canisters on a recognised list are the safest reading; the agency has the final say.
NONE
We found no canister listing requirement for this area. Hanging, lockers or poles may be the expected methods, and a canister is generally a permitted option.
VERIFY
We have not confirmed this rule from official text.

What we cannot tell you

We are not rangers, and we do not write the rules. A written rule may not match what a ranger enforces that day. A model can be sold under a new name, or recertified, after we checked. Use our answer to plan and to know what to ask, then confirm with the land manager. Our editorial policy explains how we handle corrections.
