Bob I called the Eastern Sierra Visitor Center and asked them about the bear canister. They told me via Mountaineers route it's not necessary only via main trail is it required. Also if you look at the forest service website https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb5419381.jpg
the mountaineers route falls out of the designated area
So your saying that it is still necessary via Mountaineers route.
