Nice pictures from Trail Camp and the meditating marmot. I don't think you did wrong with the sleeping bag. It's better to be too warm than too cold, especially when you're backpacking and unsure 100% what the weather will be like. I had the same issues in the Palisades this past week; sweating my butt off in the tent and had to unzip the bag and use it as a blanket. I use Diamox too, but not on this trip. I still got a headache on the sixth day when I pushed it too hard. It was fine as long as I kept a steady pace.
