The second branch is formed by two main tributaries known as Kargyag river, with its source near the Shingo La (5,091 m) (16,703 ft), and Tsarap river, with its source near the Baralacha-La. These two rivers unite below the village of Purney to form the Lungnak river (also known as the Lingti or Tsarap river). The Lungnak river then flows north-westwards along a narrow gorge towards Zanskar's central valley (known locally as jung-khor), where it unites with the Doda river to form the Zanskar river.
