b) Pasang Dorchi Sherpa - Two-time Everest summiteer and trekking guide Pasang saw Dale and Tsiring climb the 2nd step at 8600m until both of them reached the top of the step on the early morning of May 15, 2006. Pasang had to turn back from the base of the 2nd step after unloading two of Abenojar's spare oxygen bottles from his backpack because of severe frostbite to all of his toes. The top of the 2nd step to the summit is 148 meters.
