This was the last morning for a wash bucket outside of the tent, because now our water source was limited to the stagnant pool at the base of the Mawenzi Tarn. Water was the purpose for our climb, and it became a theme throughout the climb.
Conversation was nearly halted as we made our way across the saddle to our final campsite before summit night. The flat saddle was easy on the feet, but the altitude was starting to really show its presence. A stark reminder of just how dangerous this hike can be, we came across a plane wreckage from a crash in the mid-2000s.
The affects of the altitude were starting to emerge among the climbers. Headaches, loss of appetite, and even more severe effects. Day 4 took us 5.6 miles over the saddle between Mawenzi and Kibo. We increased altitude by about 1,200 ft, and that made a lot of difference. The camp at Kibo Hut was the highest most of the group had ever resided without a plane, it was at 15,419 ft.
