Eight hours of foot travel yesterday and a descent of 3,000' resulted in avoiding the normal altitude feelings of fatigue, headaches and exhaustion (sounds like fun ) were not the case this morning. We are still at over 14,000' here at Dingboche and crazy to feel like we are gathering strength for the climb ahead. The difference between 17,000' and 14,000' is dramatic in the way you feel at rest and at work. Its back up hill in the Imja Khola Valley to our last tea house in Chukung before tent time on Island Peak. RMI Guide Mark Tucker
