Tibet has some of the world's tallest mountains, with several of them making the top ten list. Mount Everest, located on the border with Nepal, is, at 8,848 metres (29,029 ft), the highest mountain on earth. Several major rivers have their source in the Tibetan Plateau (mostly in present-day Qinghai Province). These include the Yangtze, Yellow River, Indus River, Mekong, Ganges, Salween and the Yarlung Tsangpo River (Brahmaputra River). The Yarlung Tsangpo Grand Canyon, along the Yarlung Tsangpo River, is among the deepest and longest canyons in the world.
The Indus and Brahmaputra rivers originate from a lake (Tib: Tso Mapham) in Western Tibet, near Mount Kailash. The mountain is a holy pilgrimage site for both Hindus and Tibetans. The Hindus consider the mountain to be the abode of Lord Shiva. The Tibetan name for Mt. Kailash is Khang Rinpoche. Tibet has numerous high-altitude lakes referred to in Tibetan as tso or co. These include Qinghai Lake, Lake Manasarovar, Namtso, Pangong Tso, Yamdrok Lake, Siling Co, Lhamo La-tso, Lumajangdong Co, Lake Puma Yumco, Lake Paiku, Como Chamling, Lake Rakshastal, Dagze Co and Dong Co. The Qinghai Lake (Koko Nor) is the largest lake in the People's Republic of China.
The atmosphere is severely dry nine months of the year, and average annual snowfall is only 18 inches (46 cm), due to the rain shadow effect. Western passes receive small amounts of fresh snow each year but remain traversible all year round. Low temperatures are prevalent throughout these western regions, where bleak desolation is unrelieved by any vegetation bigger than a low bush, and where wind sweeps unchecked across vast expanses of arid plain. The Indian monsoon exerts some influence on eastern Tibet. Northern Tibet is subject to high temperatures in the summer and intense cold in the winter.
Cultural Tibet consists of several regions. These include Amdo (A mdo) in the northeast, which is administratively part of the provinces of Qinghai, Gansu and Sichuan. Kham (Khams) in the southeast encompasses parts of western Sichuan, northern Yunnan, southern Qinghai and the eastern part of the Tibet Autonomous Region. Ü-Tsang (dBus gTsang) (Ü in the center, Tsang in the center-west, and Ngari (mNga' ris) in the far west) covered the central and western portion of Tibet Autonomous Region.
Tibetan cultural influences extend to the neighboring states of Bhutan, Nepal, regions of India such as Sikkim, Ladakh, Lahaul, and Spiti, Northern Pakistan baltistan or Balti-yul in addition to designated Tibetan autonomous areas in adjacent Chinese provinces.
