I recommend Universal Shade from Dr. Shade. Can be worn with any baseball style hat and removed when you do not need it.( I have it on in the Avatar)
Dirty Girl Gaiters: I wear low cut footwear and these gaiters are the only ones I have ever tried that do not ride up, and they stay on. There is no cord under the foot. A small piece of velcro on the heel of your shoe holds them on. The velcro comes with the gaiter ($15, free shipping!) The same strip of velcro lasted the entire hike.
I wore the same Eco Mesh long-sleeved shirt from RailRiders everyday. Never overheated, provided UPF 30+ sun protection, dries fast and I wore it as an extra layer when it was chilly in the evenings.
There is good reason you need Ti-Calderone cones for wood fires. Fire will melt the other kind!
The best stakes were the skewer variety in those areas where the ground was hard pack. 9" Carbon Fiber stakes from Titanium Goat broke.
I was amazed at how long gas from canisters lasted. I used the ti-snowpeak stove and alternated between a large and small canister. For four days I cooked for two, for two days I boiled drinking water. Both canisters had fuel in them at the end of my hike (14 days)
The only water treatment option at the Reds Meadows store was iodine tablets. They did not have flat batteries or batteries for Steri-Pens. I did find AA batteries in the hiker box at MTR. They sell the batteries there, but the nice lady behind the counter told me to look in the Hiker Box first!
After Reds Meadows there was zero Verizon Cell Phone reception until Whitney Portal.
Mid-August. No mosquitos.
I used a 20 degree bag, SMD Wild Oasis Shelter and homemade bivy. I was glad to have each. The bivy acted as a ground cover as well as added warmth.
Somewhere along the trail, I realized since water was so plentiful, I did not have to carry any. I just treated a liter with the steri-pen and drank it on the spot before moving on. Since I have had kidney stones, I am sensitive about dehydration which causes them. I stayed hydrated. To save time in the evenings I treated three liters with chemicals and left it over night, so i would have water ready for morning.
An easy route home from Lone Pine: CREST bus to Lancaster and Amtrak. Amtrak to LA Station, express bus from LA train depot to LAX. (CREST bus does not run everyday) You can also link with Amtrak points north, Bakersfield, Fresno, San Francisco. Or, CREST north up 395 to Reno.
