Nepal measures about 880 kilometers (547 mi) along its Himalayan axis by 150 to 250 kilometers across. It has an area of 147,516 km2 (56,956 sq mi).
The Himalayas, or Himalaya, is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the Earth's highest peaks, including the highest, Mount Everest; more than 100 peaks exceeding elevations of 7,200 m (23,600 ft) above sea level lie in the Himalayas.
A canyon, gorge or chasm, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.
Upper Mustang is an upper part of Mustang District, which is located in Nepal. The Upper Mustang was a restricted kingdom until 1992 which makes it one of the most preserved regions in the world, with a majority of the population still speaking traditional Tibetic languages. Tibetan culture has been preserved by the relative isolation of the region from the outside world. Life in Mustang revolves around tourism, animal husbandry and trade.
Dhaulagiri, located in Nepal, is the seventh highest mountain in the world at 8,167 metres (26,795 ft) above sea level, and the highest mountain within the borders of a single country. It was first climbed on 13 May 1960 by a Swiss-Austrian-Nepali expedition. Annapurna I is 34 km (21 mi) east of Dhaulagiri. The Kali Gandaki River flows between the two in the Kaligandaki Gorge, said to be the world's deepest. The town of Pokhara is south of the Annapurnas, an important regional center and the gateway for climbers and trekkers visiting both ranges as well as a tourist destination in its own right.
The Yarlung Tsangpo Grand Canyon, also known as the Yarlung Zangbo Grand Canyon, the Tsangpo Canyon, the Brahmaputra Canyon or the Tsangpo Gorge, is a canyon along the Yarlung Tsangpo River in Tibet Autonomous Region, China. It is the deepest canyon in the world, and at 504.6 kilometres (313.5 mi) is slightly longer than the Grand Canyon in the United States, making it one of the world's largest. The Yarlung Tsangpo originates near Mount Kailash and runs east for about 1,700 kilometres (1,100 mi), draining a northern section of the Himalayas before it enters the gorge just downstream of Pei, Tibet, near the settlement of Zhibe. The canyon has a length of about 240 kilometres (150 mi) as the gorge bends around Mount Namcha Barwa and cuts its way through the eastern Himalayas. Its waters drop from about 2,900 metres (9,500 ft) near Pei to about 1,500 metres (4,900 ft) 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 metres (2,170 ft). The river then enters Arunachal Pradesh and eventually becomes the Brahmaputra.
The Ganges Basin is a major part of the Ganges-Brahmaputra-Meghna (GBM) basin draining 1,999,000 square kilometres in Tibet, Nepal, India and Bangladesh. To the north, the Himalaya or lower parallel ranges beyond form the Ganges-Brahmaputra divide. On the west the Ganges Basin borders the Indus basin and then the Aravalli ridge. Southern limits are the Vindhyas and Chota Nagpur Plateau. On the east the Ganges merges with the Brahmaputra through a complex system of common distributaries into the Bay of Bengal. Its catchment lies in the states of Uttar Pradesh (294,364 km2), Madhya Pradesh (198,962 km2), Bihar (143,961 km2), Rajasthan (112,490 km2), West Bengal (71,485 km2), Haryana (34,341 km2), Himachal Pradesh (4,317 km2), Delhi, Arunachal Pradesh (1,484 km2), the whole of Bangladesh, Nepal and Bhutan. Several tributaries rise inside Tibet before flowing south through Nepal. The basin has a population of more than 500 million, making it the most populated river basin in the world.
The Gandaki River, also known as the Narayani and Gandak, is one of the major rivers in Nepal and a left-bank tributary of the Ganges in India. Its total catchment area amounts to 46,300 km2 (17,900 sq mi), most of it in Nepal. In the Nepal Himalayas, the Gandaki is notable for its deep canyon. The basin also contains three mountains over 8,000 m (26,000 ft), namely Dhaulagiri, Manaslu and Annapurna Massif. Dhaulagiri is the highest point of the Gandaki basin.
Namcha Barwa or Namchabarwa is a mountain peak lying in Tibet in the region of Pemako. The traditional definition of the Himalaya extending from the Indus River to the Brahmaputra would make it the eastern anchor of the entire mountain chain, and it is the highest peak of its own section as well as Earth's easternmost peak over 7,600 metres (24,900 ft). It lies in the Nyingchi Prefecture of Tibet. It is the highest peak in the 180 km long Namcha Barwa Himal range, which is considered the easternmost syntaxis/section of the Himalaya in southeastern Tibet and northeastern India where the Himalaya are said to end, although high ranges actually continue another 300 km to the east.
Mustang District is one of the eleven districts of Gandaki Province and one of seventy-seven districts of Nepal which was a Kingdom of Lo-Manthang that joined the Federation of Nepal in 2008 after abolition of the Shah dynasty. The district covers an area of 3,573 km2 (1,380 sq mi) and in 2011 had a population of 13,452. The headquarters is located at Jomsom. Mustang is the fifth largest district of Nepal in terms of area.
The Yarlung Tsangpo, also called Yarlung Zangbo and Yalu Zangbu River is the upper stream of the Brahmaputra River located in the Tibet Autonomous Region, China. It is the longest river of Tibet and the fifth longest in China. The upper section is also called Dangque Zangbu meaning "Horse River."
The Western Himalayan alpine shrub and meadows is a montane grasslands and shrublands ecoregion of Nepal, India, and Tibet, which lies between the tree line and snow line in the western portion of the Himalaya Range.
Jomsom, also known as Dzongsam, is the centre of Gharapjhong rural municipality in Mustang district and a former independent village development committee situated at an altitude of about 2,700 metres (8,900 ft) in Gandaki Province of western Nepal. The soaring peaks of Dhaulagiri and Nilgiri form a backdrop to the town straddling the Kali Gandaki River, which flows right through the centre of Jomsom. Along the banks of the Kali Gandaki, black fossilised stones called shaligram, considered as an iconic symbol and reminder of the god Vishnu in the Hindu culture, can be found. Such stones are believed to be found only in the Kali Gandaki, and are considered holy by Hindus.
The Eastern Himalayan alpine shrub and meadows is a montane grasslands and shrublands ecoregion of Bhutan, China, India, Myanmar, and Nepal, which lies between the tree line and snow line in the eastern portion of the Himalaya Range.
The Annapurna Circuit is a trek within the mountain ranges of central Nepal. The total length of the route varies between 160–230 km, depending on where motor transportation is used and where the trek is ended. This trek crosses two different river valleys and encircles the Annapurna Massif. The path reaches its highest point at Thorung La pass, reaching the edge of the Tibetan plateau. Most trekkers hike the route anticlockwise, as this way the daily altitude gain is slower, and crossing the high Thorong La pass is easier and safer.
Thakali is a Sino-Tibetan language of Nepal spoken by the Thakali people, mainly in the Myagdi and Mustang Districts. Its dialects have limited mutual intelligibility.
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur
The Bailey–Morshead exploration of the Tsangpo Gorge was an unauthorised expedition by Frederick Bailey and Henry Morshead in 1913 which for the first time established the definite route by which the Tsangpo River reaches the sea from north of Himalaya, through the Tsangpo Gorge.
The Tibet–Nepal salt trade route is an ancient salt trading route running between the Tibetan Plateau and the Middle Hills of Nepal and further on to India. After the annexation of Tibet by China in 1950 and the Sino-Indian War in 1962, patterns of trade changed and the use of the old trading route between India and Tibet dwindled and the salt-carrying caravans became redundant.
Annapurna is a massif in the Himalayas in north-central Nepal that includes one peak over 8,000 metres (26,247 ft), thirteen peaks over 7,000 metres (22,966 ft), and sixteen more over 6,000 metres (19,685 ft). The massif is 55 kilometres (34 mi) long, and is bounded by the Kali Gandaki Gorge on the west, the Marshyangdi River on the north and east, and by the Pokhara Valley on the south. At its western end, the massif encloses a high basin called the Annapurna Sanctuary. The highest peak of the massif, Annapurna I Main, is the 10th highest mountain in the world at 8,091 metres (26,545 ft) above sea level. Maurice Herzog led a French expedition to its summit through the north face in 1950, making it the first eight-thousander to be successfully climbed.
