A Night on Everest I arrived at Camp 4 around 11:00 a.m. after a 6:00 a.m. start from Camp 3. I was still processing the one dead body that I had seen just off the main route above the Yellow Band four hours earlier. How long had they been there? Who was that? I wanted answers then, but I was just trying to keep moving at over 25,000 ft. I was climbing with an 18 lb. bottle of oxygen with a three liter per minute flow rate. I was more worried about leaving for the summit after what I had just seen. We crossed the Geneva Spur at around 10:00 a.m. and made our way to the South Col and Camp 4. Climbers were descending from the first of the two good summit days of the 2019 season. It was May 22. It was partly cloudy and windy. Half of my IMG (International Mountain Guides) group had already summited and were either descending or resting at Camp 4 while my group was just getting into Camp 4. I wanted to hear about the climb and what had happened, but those descending from the summit were either crashed and asleep or not back down from the summit. I was also exhausted and happy to crawl into my temporary tent and unstuff my sleeping bag and sleeping pad. While I was resting, Chris arrived and joined me in the tent. We could hear talking on the nearby radios that our Sherpa and guides shared. On the radio we could hear one of our team asking for help. She was on the Balcony, about half way down from the summit, and she was not feeling well. She was told to get something to eat and drink and then continue down. We had no idea that she had symptoms of pulmonary edema on the Hillary Step. Chris and I were on oxygen at one liter per minute while inside our tent. The idea of pulmonary edema scared me. 16 JA NUA RY/F E B R UA RY 2020 | P EN N S YLVA N IA D EN TA L J O U R N A L Summit The Hillary Step 29,029 ft. as only one mountaineer can ascend at a time.
