Sources The Charding Nullah originates below the Charding La pass, which is on a large spur that divides the
Sutlej river basin from the
Indus river basin. In this area, the Sutlej river tributaries flow southeast into West Tibet and the Indus river and its tributaries flow northwest, parallel to the Himalayan ranges.
Charding–Nilung Nullah Junction The Charding Nullah flows northeast along a narrow mountain valley. Halfway down the valley it is joined by another nullah from the left, called Nilung (or Nilu/Ninglung). The
Charding–Nilung Nullah Junction (CNNJ, 4900 m), near
Nilding, is recognised by both the Indian and Chinese border troops as a strategic point. Nilung River originates from the
Nilun La, which lies west of
Charding La. In the Indian administered area are the
Lungkar La (5,795 m or 19,012 ft, north of Nilung stream),
Jamlung La (west of Nilung stream) and
Umling La (5,798 m or 19,024 ft, northwest of Nilung stream), all connected by the
BRO Roads from the India side from Chisumle, over these passes and to the left bank of Nilung stream and the left bank of Chardhing Nullah to Demchok. The right bank of Chardhing Nullah is administered by China.
Changthang plateau The entire area surrounding the Charding Nullah is referred to as the
Changthang plateau. It consists of rocky mountain heights of
Ladakh and
Kailas ranges and sandy river valleys which are only good for grazing yaks, sheep and goats (the famous
pashmina goats) reared by Changpa nomads. The Indian-controlled northern side of the nullah is close to
Hanle, the site of the
Hanle Monastery. The Chinese-controlled southern side has the village of
Tashigang (Zhaxigang) which also has a monastery, both having been built by the Ladakhi ruler
Sengge Namgyal (). At the end of
Tibet–Ladakh–Mughal War, the Tibetan troops retreated to Tashigang where they fortified themselves.
Mouth At the bottom of the valley, the Charding Nullah branches into a 2 km-wide delta as it joins the Indus river. During the
British colonial period, there were villages on both the sides of the delta, going by the name "Demchok". The southern village appears to have been the main one, frequently referred to by travelers. == Sino-Indian border dispute ==
