Kosmos gyala peri
Gyala Peri (Chinese: 加拉白垒, Pinyin: Jiālābáilěi) is a peak just beyond the eastern end of the Himalayas at the entrance to Tsangpo gorge. It is part of Nyenchen Tanglha Shan, although it is sometimes included in Namcha Barwa Himal of the Himalayas.
Gyala Peri lies just north of the Great Bend of the Yarlung Tsangpo River, the main river of southeastern Tibet, which becomes the Brahmaputra in India. It is 22 km NNW of the higher Namcha Barwa.
Gyala Peri has great vertical relief above the Tsangpo gorge and is the highest peak of the Nyenchen Tanglha Shan.
The first ascent of Gyala Peri was in 1986, by a Japanese expedition, via the South Ridge. The group spent about one and one-half months on the mountain. The U.K. Alpine Club's Himalayan Index lists no other ascents.
