It appears to be about a 25 mile lollipop loop with about 7500 ft elevation gain that I am thinking of doing in two days / one night in beginning to mid-October. The reason why I am considering October is because of fall colors plus it seems that thunderstorm season is over. This will be my first time in Colorado. A few questions…
1)Am I being too aggressive doing it in two days? To compare, I just did 60 miles from South Lake to Onion Valley which included 12,500 ft elevation gain in 4 days. Also, I should be 7lbs lighter in Colorado (total 22lbs) though the average elevation/altitude will be higher.
2)Will water be plentiful?
3)What kind of temperature ranges should I expect so I can bring the right sleeping bag and jacket?
4)I would be flying in and taking a chance on weather. Previous or forecasted snow buildup on the trail would cause me to cancel. Based on my timeframe am I taking too much of a chance on a $200 ticket? Worst comes to worst I can cancel or pick a lower elevation trail.
5)I believe bear cans are not required, however, what do people do to protect food from little critters? I do not plan on any side trips so my food/backpack will always be with me. Would something like the Ursack/OPSAK combo be sufficient? I have always used a bearvault before which I would be happy to leave at home.
6)Any special gear considerations above and beyond a standard JMT hike?
