The previous night had been unusually warm, despite the dew that covered our shelter, bivy sacks, and sleeping bags. Despite this, I hadn't slept well: the previous night's dinner--barbecue beef wraps--hadn't sat well with me, and I woke up with a distinct lack of appetite and energy. The consensus was that I had been hit by altitude sickness (with some food-related illness the runner-up diagnosis)--despite the modest elevation and the fact that I'd spent several nights over the past week or so in Tuolumne Meadows. Symptoms aside, I should have been well acclimated. I skipped most of breakfast, and I barely had enough energy to help break camp, preferring to lay down and rest whenever possible.
Fortunately, the first part of this day's leg was downhill, and I reached Rush Creek without too much difficulty. The clouds had stayed with us all night, and a light overcast was present as we hiked towards Thousand Island Pass and beyond. I had to rest several times while climbing this minor pass, and I contemplated that if I didn't improve, there was no way I could climb the real passes along the JMT.
I did finally make it to the top of Thousand Island Pass, where I rested and attempted to eat a bit more. A prepared an electrolyte drink for me, which seemed to help a bit with my (lack of) appetite.
After resting for awhile, I continued down to Thousand Island Lake. Despite the clouds, the sun was quite strong, and I sought out a small tree for shade to rest under once near the lake's outlet.
The others in the group decided to take advantage of the sun and warm water and announced that they were going skinny-dipping in the lake. Despite my protestations "sick, not dead", I felt closer to the latter than the former and chose to rest some more.
We discussed dropping to a lower altitude--the correct recourse if in fact I had altitude sickness--but other than lethargy, I wasn't feeling that bad. (In fact, I was probably hiking about as well as the "average" hiker in this area, based on my comparative pace.) I didn't have a headache or nausea, and I was able to eat--a bit.
The original plan was to include four Sierra High Route segments on our JMT trip--the first would have started at Thousand Island Lake and went around its head, over to Garnet's head, then over Whitebark Pass--we would convene for camp somewhere along Shadow Creek. My illness took this segment out of consideration--but there was still a chance that we could do the Ediza-Iceberg-Cecile-Minaret Lake
We left Thousand Island Lake and headed towards Garnet Lake--and perhaps beyond.
By the time we were at Garnet, I was in fact feeling much better. We had decided to not camp where the trail first hits the lake (at the "terraces"

For the next several hours we watched from underneath our shelter as heavy rain fell on us and the lake. A few times we had to divert water from flowing under our shelter--the sand we were camped on had become saturated with rain. Thunder echoed around us, and a few strikes were only a mile or two away. Still feeling drained, I slept on and off during most of this storm. We had a direct view of Whitebark Pass, which in retrospect would not have been a good place to have been this afternoon.
We were able to contact the H party via radio; they had camped at the "terraces", all three of them crammed into their Fly Creek UL2, a tent I consider a comfortable one-person shelter. At least they were warm and dry.
Just as the sun was ready to disappear behind the Ritter Range, the rain let up, and we had a few moments of filtered light.
We were able to enjoy dinner "outside", and after the sun set we slept warm and dry. It had been a short day, but between my condition and the weather, I don't think we could have pushed much further, and on previous trips we knew that Garnet was by far the best camping until well past Reds Meadow, which we would easily be able to make by mid-afternoon the next day, even if we took the JMT instead of dropping at Garnet or Shadow to the River Trail. The first segment of the High Route was off the table, but we had three more planned.
