The New Largest Canyon in the World 
---The Great Canyon of Yarlung Tsangpo River (Tibet)--- |
We all fallen in love with the Grand Canyon of Colorado River - depth 2,682m (8,799 ft), length 440 km. It was one of the 7 Natural Wonders of the world.However since 1994, we learned from the American Geography Committee and Guinness Book of World Records that the crown of the "world's largest canyon" went to the Great Canyon of Yarlung Tsangpo (Brahmaputra) River in Himalayas (Tibet).  Its depth reaches 5,382m (17,657 ft) and it has a total length of 496.3km.
However very little information about this new Queen of Canyons is available to the world.Because very few people have reached that remote region in Tibet. (some regions are forbidden for the foreigners to access). What is the features of this mysterious new Queen of the world's canyons? Is she beautiful? attractive? or is she dangerous with bad temper?
To satisfy the curiosity of world public, we piled the major facts here.

| Himalayas & Tibet Plateau - the miracle ofPlate-Tectonic Force:
The collision of India into Asia some 50 million years ago caused the Eurasian Plate to crumple up and override the Indian Plate. It pushed up the Himalayas and the Tibetan Plateau to their present heights. The Himalayas, towering as high as Mt. Everest's 8,850 m (29,035 ft) elevation, forming the highest mountain range in the world. Moreover, the neighboring Tibetan Plateau,at an average elevation of about 4,600 m (15,091 ft), is higher than all the peaks in the Alps except for Mt. Blanc and Monte Rosa, and is well above the summits of most mountains in the United States. |

Where is the Yarlung Tsangpo River and the Largest Canyon of the world?
The largest canyon of the world is located at the South end of the Himalayas range in Tibet.
Originating inmiddle Himalayas,  countless tiny drops from the 5,590 meters high Jima Yangzong Glacier source come down and converge into the river. It keeps flowing eastward and getting bigger and bigger as the Nyang Chu, Kyi Chu, Yarlung, Ni Yang and other streams join in. The  Yarlung Tsangpo River, known as the Brahmaputra river in India, the Siang or Dihang in Arunachal Pradesh and the Jammu in Bangladesh, is one of the largest rivers of the world.
The 2,057 km traverse of Yarlung Tsangpo River on the world's roof, with an average altitude of >3,000 meters, is the highest rive in the world. Then it drops down to the Indoa plain, after 918 km in India and 337 km in Bangladesh, ended into the Bay of Bengal |       |

| Two High Peaks, Two Big Bends at the Two ends of theHimalayas range - the frontier of the plate-tectonic force:
The red line in the left figure shows the collide border of Eurasian continent and India sub-continents. It is interesting that there are two big bends of rivers formed at the east and the west ends of the Himalayas range. The Yarlung Tsangpo River made a U turn when it reached the highest peak of east Himalayas - the Mt. Namcha Barwa(7,782m). The Indus River made a U turn  when it reached the high peak of west Himalayas - the Mt. Nanga Parbat (8,125m).
These high peaks and deep valleys were formed along the  narrow frontier zones between the Eurasian and India sub-continent where the results of plate-tectonic forces are most evident. The geological characters of this region is extremely rich, complex and unique. This rock (leftlast photo) came from the core (about 40 km depth) of |Earth. Its red component can be used to make red diamond. |
