I am going to be doing the Teton Crest Trail the first Week of September this year and am curious as to what weather to plan for? I will be camping between 9,000 and 9,500ft. Should I expect temps around freezing at night and 70* in the daytime? I am trying to figure out what to bring for my sleeping system.
I spent a week in the Winds last year about that time camping about 10,000ft but it was unseasonably warm and only got below freezing one day.
