The Indus River Valley was formed by the main channel of the Indus River as it flows across Ladakh. The source of the Indus River is in the Tibetan plateau of western China in the vicinity of Lake Mansarovar near the Mount Kailash. The river runs a course through the Ladakh district of Jammu and Kashmir and then enters Pakistan. The Ladakh valley is surrounded by the Ladakh Range in the north and the Zanskar Range in the south.
