With all my partners being caught up in work and only one day of good weather I decided to solo the route in one push from the valley. Shortly after starting at 1am just above Grindelwald, the cloudless sky would light up nearly every minute. Lightning in the far, already. The weather was supposed to deteriorate only after noon! Reaching the Guggi hut with first light I have the pleasure to enjoy the sunrise over the surrounding stunning peaks, Eiger, Mönch, and Jungfrau. All to myself. The last climb of the route must have been at least a weak ago. The climbing is great and enjoyable. But, the weather changes. Clouds move in and out. The final snow slope takes the last bits out of me. Spending the previous week at the sea, acclimatizing to literally 0m altitude, my lungs are working hard at now nearly 4000m. On the summit ridge I have to walk even slower because I can hardly differentiate the ground from the sky. Complete whiteout. Upon reaching the summit, the clouds break away and I am once more greeted with stunning views of the Bernese Oberland. What a great summit!
The way down is straight forward. The good track of the normal route down to the Aletsch glacier quickly takes me back to the Jungfraujoch where civilization catches up to me. Hundreds of people enjoying the high altitude mountain environment.
