The bear canister rule...and I will paraphrase, any container manufactured to keep food safe from bears. An Ursack meet that criteria. If you search the Inyo website you will find the exact wording or a link to another government website that will send to you to another government website that will send you back to the Inyo. This why Mt. Whitney can be so frustrating.
I've always attempted a warm meal. The thoughts of not having something hot is anathema to me.
I have used rain pants at Mt. Whitney for wind protection twice in seven summit trips.
