The Himalayan arc extends about 2400 km from Nanga Parbat (8,138 m) by the Indus River in northern Pakistan eastward to Namche Barwa (7,756 m) by the gorge of the Tsangpo-Brahmaputra in eastern Tibet (Le Fort 1996). About 800 km of this extent is in Nepal; the remainder includes Bhutan and parts of Pakistan, India, and China.
