Our main objective was to make the first ascent of Dih Sar 6,207m by the east ridge. Our plan involved crossing Joshi Pass 5,423m to reach base camp in the Dih Dur Valley. Unfortunately, Tim got altitude sickness approaching the pass and he returned to Shimshal village to recover. Meanwhile porters carried some climbing gear, a tent and some supplies up to Joshi Pass so Tim and I could operate from there if he returned. We would either go down to Dih Sar base camp to attempt Dih Sar or climb peaks above the pass. While Tim walked back to Shimshal village with the porters, I went up to the pass alone. The next day I climbed along a ridge north of the pass. This was the south ridge of Shar Izat Peak 5,930m, which had been climbed previously by a different route. I crossed two tops on the ridge which was easy (Facile grade) but corniced, and after 1.5 kms reached a third top, the highest at 5,696m (GPS). According to Janusz Mayer, who led a 2022 attempt on Dih Sar, these tops are probably unclimbed. They are marked as 25,26 and unmarked on the Jerzy Wala map. My high point had little prominence as beyond it the ridge dropped a short distance to a col before rising up towards a top marked 29 and then the summit of Shar Izat Peak. The ground ahead looked trickier for solo climbing, so I returned to my tent at the pass. The next morning, I learned by Inreach that Tim was not coming back up, so we arranged porters for our return to Shimshal village, ending the expedition.
