Osmaston surveyed the Sanctuary's northern glacier while Shipton explored the Changabang glacier. While Osmaston turned to the southern glacier, Shipton descended the Rishi Ganga gorge, made a failed attempt on Dunagiri, crossed the Bagini Pass and descended the Bagini glacier to the north. Returning to Joshimath he took up a phototheodolite and went south to survey the Rinti glacier and the saddle between Trisul and Nanda Ghunti.
