Namcha Barwa Himal

Namcha Barwa Himal, also known as Namjagbarwa syntaxis or Namjagbarwa Group Complex, is the easternmost section of the Himalaya in southeastern Tibet and northeastern India. This section spans 180 km from the headwaters of the Siyom River on the international border NE into Tibet to the canyon of the Yarlung Tsangpo (the Brahmaputra in India), where the Himalaya are said to end, although high ranges (Hengduan Mountains on China–Myanmar border) actually continue another 300 km east.

Major peaks of this section include:


 * Namche Barwa, 7,782 m at 29.62917°N, 95.05583°W, considered easternmost syntaxis of Himalaya


 * Nai Peng, 7,043 m at 29.62°N, 95.05°W, first climbed 1984


 * Sentang Bu, 6,812 m at 29.83°N, 95.01°W, unclimbed


 * Gyala Peri, 7,294 m at 29.81417°N, 94.96833°W, part of Nyenchen Tanglha Shan range, stands about 22 km NNW of Namche Barwa, across the Yarlung Tsangpo but often included in the Namche Barwa Himal range because of proximity.
