All available maps and atlases (including a detailed delineation of the Siachen Muztagh's limits on the 1990 Swiss Foundation for Alpine Research Karakoram Sheet 2 map) define the range as between the Shaksgam River on the north, the Urdok Glacier on the northwest, the Siachen Glacier on the southwest, the Teram Shehr and South Rimo Glaciers and Indira Col on the south, and the uppermost Yarkand River on the east.
