The first ascent of Saltoro Kangri was in July 1962, by a joint Japanese-Pakistani expedition led by T. Shidei. This piggyback expedition put A. Saito, Y. Takamura and Pakistani climber R.A. Bashir on top on July 24, following the S.E. ridge route. This peak was climbed by an Indian Army expedition led by Colonel Narendra Kumar in 1981. US maps of the area and many world atlases starting in the 1960s showed the Line of Control between Pakistani and Indian territory running from the last defined point in the 1949 Karachi Agreement, NJ9842, east-northeast to the Karakoram Pass, thus putting the whole of Saltoro Kangri and the entire Siachen Glacier in Pakistan. However, the Simla Agreement defined the Line of Control no further than point NJ9842 other than with the phrase thence north to the glaciers. The Himalayan Index lists only one more ascent of the mountain, in 1981, and no other attempts.
