At 6:20 when Ang Dorjee and I stepped out from the South Col, it was a perfect day. There was a gentle breeze but the cold was intense. I was, however, warm in my well-insulated (covered as not to allow heat to go out) climbing gear.We climbed unroped (without taking help of a rope). Ang Dorjee set a steady pace but I had no difficulty keeping up with him. The steep (a sharp slope) frozen slopes were as hard and brittle (easily breakable) as sheets of glass. We had to use the ice-axe and I had to kick really hard to get the front teeth of the crampons (boots with spikes) to bite into the frozen surface. I took every step very deliberately on the dangerous stretches.In less than two hours, we reached the Summit Camp. Ang Dorjee looked back and asked if I was tired. I replied, “No,” to his surprise and delight. He told me that the earlier Summit Party had taken four hours to reach the Summit Camp and added that if we could keep our present * pace, we would be on the Summit by 1:00 p.m.(1) How was Bachendri warm in spite of the intense cold ?(2) How did they start climbing?(3) How had she to use her ice-axe ?(4) Bachendri and Ang Dorjee climbed faster. How can you say so?(5) How would they be able to be on the Summit by 1:00 p.m.?
