Mt. Kailash is a mountain in western Tibet. It lies near the source of some of the longest rivers in Asia: the Indus River, the Sutlej River (a major tributary of the Indus River), the Brahmaputra River, and the Karnali River (a tributary of the Ganges River). It is considered a sacred place in four religions: Bön, Buddhism, Hinduism and Jainism.
