The Yarlung Tsangpo Grand Canyon is regarded by some as the deepest canyon in the world

The Yarlung Tsangpo Grand Canyon or Yarlung Zangbo Grand Canyon or simply the Tsangpo Canyon or Tsangpo Gorge, along the Yarlung Tsangpo River in Tibet, China, is regarded by some as the deepest canyon in the world, and is slightly longer than the Grand Canyon in the United States, making it one of the world's largest. The Yarlung Tsangpo (Tibetan name for the upper course of the Brahmaputra) originates near Mount Kailash and runs east for about 1700 km, draining a northern section of the Himalayas before it enters the gorge near downstream of Pei, Tibet near the settlement of Zhibe. The canyon has a length of about 150 miles (240 km) as the gorge bends around Mount Namcha Barwa (7782 m) and cuts its way through the eastern Himalayan range. Its waters drop from about 2,900 m near Pei to about 1,500 m at the end of the Upper Gorge where the Po Tsangpo River enters. The river continues through the Lower Gorge to the Indian border at an elevation of 660 m. The river then enters Arunachal Pradesh and eventually becomes the Brahmaputra.

 

The Yarlung Zangbo Grand Canyon is the highest green land on earth. Green mountains have snow-covered peaks poking through the clouds. Visitors come to see the area's mountain belts, unusual plants and animals, and mysterious cultures. The Yarlung area is home to many living species. Preliminary statistics show that there are over 3,768 varieties of plants, 680 varieties of large fungi, 232 species of birds 31 species of amphibians, 2,000 kinds of insects and over 230 rust fungi.
The Yarlung Zangbo Grand Canyon stretches 496-kilometers long and averages over 5,000 meters deep. It measures 21-kilometer wide and even at the narrowest part it has a depth of 5,138-meters. It is the deepest, narrowest and longest canyon of the world as compared to the other grand canyons in the world; Furthermore, the natural landscape is also unmatchable in the world.

The abundant rainfall and the geomorphology of high mountains and deep gorges in this area have helped to form lots of glaciers, snow-slides and waterfalls, lakes and springs that, together with the roaring river, make up the attractive and fanciful natural sights.

A varied and changeable climate makes the canyon a place of different landscapes. Areas lower than 1,100 meters above sea level and with annual mean temperature of 16? to 18? have tropical rainforests and a variety of crops, including thermophilous crops and tropical and subtropical trees. Between 1100 meters and 2,400 meters above sea level with an average mean temperature of 11? to 16?, there are evergreen and broad-leafed trees. Between 2,400 meters and 3,800 meters with annual mean temperature of 2? to 11?, there are conifer forests, winter crops and timber production. At 3,800 meters above sea level, the climate is cold and moist and there are large mountain meadows and good-quality highland pastures in the summer.
