Where is the deepest river?

Yarlung Zangbo Grand Canyon, the deepest and longest river canyon in the world. The peaks and valleys are close at hand, and the strong terrain contrast of nearly 10,000 meters constitutes the first magnificent landscape in the world. The Yarlung Zangbo River is the highest river in the world, with an average elevation of over 3,000 meters. Its downstream surrounds the highest peak at the eastern end of the Himalayas, forming a peculiar horseshoe-shaped bend, cutting a huge canyon 504 kilometers long on the Qinghai-Tibet Plateau. The average depth of the canyon is 2268 meters, and the deepest part is 6009 meters. It is undoubtedly the largest canyon in the world. The Colorado Grand Canyon in the United States and the Colca Grand Canyon in Peru were once ranked as the highest in the world, but neither of them can be compared with the Yarlung Zangbo Grand Canyon.
