This question is prompted by the replies to Questions about specifics of black bear encounter with mother and yearling cub. That question was about an encounter over 30 years ago, before the era of portable bear canisters, or at least before they were routinely used. And it was a 14 day trip, and there is no way we could have carried enough canisters for a 14 day trip. Maybe some of you supermen could have! So...the current question.
From my point of view, this question is theoretical, because we aren't going on any more 14 day backpacking trips without assistance from a packer. But I am curious.
How can food be properly stored against black bears on a long (say 14 day) backpacking trip at least partly in black bear country? Assume no campsites with established bear boxes beyond the first and last days. Assume no brown bears.
Can you really carry enough bear canisters? If so, tell me how! Do you rely on trees (bear-bagging)? Or what?
In the Sierra, with black bears, we have dug into snow banks to store food where there were no good bear-bagging trees available. This has never failed, and in several cases we know there were bears around (pawprints, neighboring campsite being ripped off, notorious bear traffic.)
