Wow Bob, I didn't know you did Denali. Your prolific peak bagging in the Sierra is very impressive, but Denali is another level entirely. I'm in the middle of a climbing history book on Denali right now. The weather is so extreme, that's not even on my bucket list. We seem to have a similar style of not taking breaks, but you would surely leave me in the dust.

My symptoms, described above, started while sleeping above Guitar Lake, after several days above 10,000. I should've realized it was not AMS, but rather dehydration. Bad decision on my part to take Diamox at 2am. Hopefully some one else will benefit from reading about that mistake.
