Nyenchen Tanglha[2][3] or Nyainqêntanglha (Tibetan: གཉན་ཆེན་ཐང་ལྷ་, Wylie: Gnyan-chen-thang-lha; Chinese: 念青唐古拉山, Pinyin: Niànqīng Tánggǔlā Shān) is a 700km long mountain range located in the Tibet Autonomous Region (China), at an average latitude of 30°30'N and a longitude between 90°E and 97°E. Together with the Gangdise (Gangtise) range located further west, it forms the Transhimalaya (or Gangdise-Nyenchen Tanglha range), which runs parallel to the main Himalayan range north of the Yarlung Tsangpo river. The range is divided into two main parts: the West and East Nyenchen Tanglha, with a division at the 5432m high Tro La pass near Lhari.
