. The combined river flows in the same valley and in the same direction as Gar Tsangpo. Thus by physical geography, Gar Tsangpo is the "Indus River". The Tibetans however regard Sênggê Zangbo as the main Indus River, and treat Gar Tsangpo as a tributary.

Course

The sources of Gartang are on the southwestern slopes of the
Kailas Range (Gangdise Shan). From there, the river flows northwest in the Gar Valley, the tectonic valley between the Kailas Range and the
Ladakh Range. The slope of the valley is extremely gentle, only about 2 metres per kilometre.
After a distance of , the Gartang joins
Sengge Zangbo (Shiquan He), which originates on the northern slopes of
Mount Kailas and flows in a wide arc towards the Gar Valley. The point of confluence is near the town of
Tashigang (Zhaxigang). After the confluence, the combined river, regarded as the
Indus River

, flows in the same direction as Gartang. For this reason, western explorers have traditionally regarded Gartang as the main source of the Indus River. However, the Tibetans regard Sengge Zangbo as the main Indus River and the Gartang as its tributary.
The Gartang river drains an area of 6,060 km2.
History
Two well-known villages cum encampments,
Gar Yarsa and
Gar Gunsa, lie along the course of the Gartang, separated by . The two locations together have been called "Gartok" and served as the administrative headquarters of
Ngari (West Tibet) during the
Ganden Phodrang administration of Tibet. The Lhasa-appointed administrator, called Garpön, used to stay at Gar Yarsa during the summemr months, and at Gar Gunsa during the winter. After the
Chinese annexation of Tibet in 1950, the headquarters of Ngari was moved to a new town of
Shiquanhe on the Sengge Zangbo river.
