For the past month, I've been trying to sort out Canister requirements on the JMT. My confusion stems from (among other things) the Inyo NF webs site nomenclature, as is mentioned below.
I just received the following e-mail from a Yosemite biologist quoting a Inyo NF ranger. I'm heading out of town, so can't I follow up. But this 3rd hand info starts with "Canisters are not required along the entire JMT."
My take on this is to call Inyo for clarification.
If anyone else is pursuing this, please post your findings.
"Sorry for the delayed response. Below is an explanation of the mandatory canister areas on the Inyo NF. Canisters are not required along the entire JMT. The below information is from an Inyo NF wilderness ranger."

"Information from the Inyo NF:
Food storage requirements are based on where you are camping, noton your entry point. The list of trails where canisters are required is just entry points that begin in a mandatory canister use area. The idea was to alert people to look more closely for how their travel plan may be affected. We are currently revising much of our website, and will try to better clarify this topic.
Some of the confusion comes from the problem we created when we named these two trail head quota designations at Devils Postpile/ Reds Meadow after our Famous feature, the John Muir Trail. Our wilderness management plan and trail name list, use the name John Muir North to denote the section of the John Muir corridor that is just north of Devils Postpile. The John Muir South, does not mean the entire JMT Corridor, just the segment immediately south of Devils Postpile and Reds Meadow.
The canister required maps should always be referred to for the exact boundary of where the higher standard of food storage is required.
Let me give some examples for this area:
1. Group one starting at Devils Postpile and going south on the John Muir to camp at Virginia Lake. Trail name for the purpose of entry quota is JMT South. Canister is required because they are camping within the required area.
2. Group two starting at Devils Postpile and going south on the John Muir to camp their first night at Tully Hole. Trail name for the purpose of entry quota is JMT South. Canister is not required because they did not camp in the canister required area.
3. Group three starting at Laurel Lakes trailhead. The first night camp is at Lake Dorothy, the second night camp is at Lake Virginia. This group is required to fit all their food and refuse in canisters by the second night, at Lake Virginia because they are now within the canister required area.The first night they would have the option to use other methods to secure their food."
