We’ve just arrived in C4 at 7475 m, officially death zone and I feel more dead than alive. We climbed 1250 m up and descended 530 m to get here and some very steep stretches. Technically not difficult at all, but some very long. Also a couple of really sneaky steep ice stretches at the end of the snow walls which take your final breath. Hardly ever been gasping so much. Luckily Pemba has given up the idea to skip C4. It would be absolutely idiot to continue, if only for the fierce winds There are probably good reasons for selecting the spot of C4, but it is an extremely windy spot. The wind was a very serious factor in any case today. At many stretches it blew the tracks away instantaneously making it a lot more difficult to get up in knee-deep snow. Slowly other teams are flocking in, glad we have pulled up our small tent so fast as it shields from the wind. Pemba already makes me coffee. Considering sleeping with my down-suit on tonight as it is freaking cold. My water bottle was frozen in my backpack… We plan to start our summit push around 1 or 2 h, depending on the conditions. There is quite a bit of moon light (full moon a week ago) so hopefully not to many clouds.
