Incas trail. Peru
Date: Sept, 1999
Distance: 50 km.
Details: backpacking.
Dana at 13700 feets. I felt a bit light head, and nauseous.
Group related after lunch on day 2. We were tired after the first pass.
After lunch, we descend the valley, camped there for the second night at 12500 fts.
I had trouble to breath that night. Probably lack of oxigen.
