Steve:
I already carry the gravity filter which contains a 3 liter dirty bag and 3 liter clean bag. I also carry an emergency sealed water bottle (about 1/4 liter). I also carry a 0.5 liter water bottle with powerade. So just filling my clean bag & water bottle with 3.0 liters of water at the last tarn before switch backs should do it. Depending on how I feel about the back pack weight at the trail crest, I may leave some stuff in a cloth bag (like my kitchen, extra clothing, med bag, bear-proof container, water filter etc) covered with my backpack rain cover at the trail crest.
Again thanks for the water needs advice. I should be fine with dry snacks and cold coffee on the summit.
