Turning back at 8500 Meter

Our way up was very cold and windy. But nevertheless I was fit and had no problems with the thin air. At an altitude of 8500 meters I double-checked the mice. I found them in a in a very bad condition and was afraid they won’t survive the cold. With a heavy heart I decided to turn back – 300 meters of altitude difference below the summit. I went down to camp 2, where we analyzed the mice and ensured the results.
