We are group of 10 friends hiking Mt Whitney (day hike) on Sep 18th 2017. We are excited and nervous as days are chugging along and September is nearing. I have some questions.
1) How is the weather during day time in September?
2) Will there be lot of snow on switchbacks in September (given this year around, there was significant amount of snow)?
3) We are group of 10. We plan to start the hike by 12:30am. Does it seem reasonable time to start? We are estimating 1mile per hr, so it would take 11-12hrs to reach summit. Is this good estimate, over estimate?
4) We are arriving in Lone Pine on Sep15th. What is the good place to get acclimatized and does 4-5hr stay help?
