They started climbing upstream of the Saukdara river and continued climbing along the Greater Saukdara Glacier towards the Krilenko Pass at 5820 m. On September 25, 1928 they started climbing from the saddle along the NE Ridge and at 15.30 they made the first ascent of Lenin Peak at an altitude of 7127 m.
