The Shyok River flows through the disputed Ladakh of India and the disputed Northern Areas of Pakistan (Ghangche District), spanning some 550 km (340 mi). It originates from the Rimo Glacier, one of the tongues of Siachen Glacier. The river widens at the confluence with the Nubra River. The alignment of the Shyok river is very unusual, originating from the Rimo glacier, it flows in a southeasternly direction and joining the Pangong range, it takes a northwestern turn, flowing parallel to its previous path. The Shyok flows in a wide valley, suddenly entering a narrow gorge after Chalunka and then joining the Indus at Keris.
