The Yarlung Tsangpo Glacier, also known as the Siang Glacier or the Brahmaputra Glacier, is located in the eastern district of Mustang in Nepal. It is the largest non-polar glacier in the world, measuring about 15 miles (24 kilometers) long and 1.2 miles (2 kilometers) wide.
The glacier is part of the Yarlung Tsangpo River basin, which is one of the largest river systems in Asia. The river originates from the glacier and flows eastward through Tibet, China, and eventually enters India, where it is known as the Brahmaputra River. In Nepal, the river is known as the Karnali River.
The Yarlung Tsangpo Glacier is an important source of freshwater for the region, providing water for irrigation, drinking, and other uses. However, like many other glaciers around the world, the Yarlung Tsangpo Glacier is rapidly retreating due to climate change. This has significant ecological impacts, as the loss of the glacier can lead to changes in the river flow, affect the aquatic ecosystem, and impact the livelihoods of the local communities who depend on the river for their survival.
