The Yarlung Tsangpo is a major river in Tibet, known as the upper stream of the Brahmaputra River. It originates from the Angsi Glacier in the Himalayas and flows through the Yarlung Valley, which is significant in Tibetan culture and history. As it travels southeast, the Yarlung Tsangpo carves through deep gorges and stunning landscapes, eventually entering India and Bangladesh. The river is crucial for irrigation and supports diverse ecosystems, making it vital for the communities that depend on its waters.
