The Indus rises from the springs of Sin Khabab glacier about 100 km. north of Mansarovar in Tibet. It traverses 250 km. in Tibet before entering Kashmir.
It traverses Kashmir diagonally for a distance of 650 km. remaining confined within a narrow gorge, 10 km. wide on an average. Before entering Pakistan, the Indus takes a sharp southerly turn, cutting the Ladakh range through the world’s deepest gorge, 5,200 m. deep near Bunji.
