| Route Notes | BC near Mingbo C2 on SW Rridge. South face too dangerous from big rocks falling so went to SW Ridge for entire climb of normal route. No problems on climb: 2 did not summit because one was sick and other not capable enough climber. 6 members left before climbing finished because their climbing had finished. Joos summited a second time because his friend Marugg had been silently sick earlier and now wanted to go to the top. Last 4 members at BC left it 20 Oct. |
