These ranges run north to south through southwest China, a geological anomaly created by the Indian subcontinent's collision with the Eurasian Plate, their ridges and gorges carved by the Yangtze, Mekong, and Salween as these rivers drain the eastern Tibetan Plateau. Stretching approximately 900 kilometers from 33 degrees north to 25 degrees north, the Hengduan connect the southeast Tibetan Plateau with the Yunnan-Guizhou Plateau, forming a wall that separates the lowlands of northern Myanmar from the Sichuan Basin. Their highest point, Mount Gongga, rises to 7,556 meters, the tallest peak east of the Himalayas.
