I have a 4 day trip planned from Cottonwood Lakes to Whitney Portal with some friends. Originally we were going to go in early September. I have a friend who wants to join us but can't go until later. I've only been out there in August and early September. What is weather typically like late September/beginning of October? I'm sure it depends on the year somewhat. I'd like to avoid snow shoes, crampons, axe, etc and I'm trying to figure out how late I can plan the trip and still be somewhat sure that I won't need to bring winter gear along.
