The Himalayas, or Himalaya ( /, / ; Sanskrit: IPA: [ɦɪmɐːləjɐː] , himá "snow", ā-laya "dwelling", "abode" ), are a mountain range in Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the highest, Mount Everest. Over 100 peaks exceeding 7,200 m (23,600 ft) in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is 6,961 m (22,838 ft) tall.
The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China.The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas. The Himalayas have profoundly shaped the cultures of South Asia and Tibet; many Himalayan peaks are sacred in Hinduism and Buddhism.
Lifted by the subduction of the Indian tectonic plate under the Eurasian Plate, the Himalayan mountain range runs west-northwest to east-southeast in an arc 2,400 km (1,500 mi) long. Its western anchor, Nanga Parbat, lies just south of the northernmost bend of the Indus river. Its eastern anchor, Namcha Barwa, lies immediately west of the great bend of the Yarlung Tsangpo River. The range varies in width from 350 km (220 mi) in the west to 150 km (93 mi) in the east.
The name of the range hails from the Sanskrit Himālaya ( हिमालय 'abode of the snow'), from himá ( हिम 'snow') and ā-laya ( आलय 'receptacle, dwelling'). They are now known as "the Himalaya Mountains", usually shortened to "the Himalayas". Following the etymology some writers refer to it as the Himalaya. This was also previously transcribed as Himmaleh, as in Emily Dickinson's poetry and Henry David Thoreau's essays.
The mountains are known as the Himālaya in Nepali and Hindi (both written हिमालय), Himāl (हिमाल) in Kumaoni, the Himalaya (ཧི་མ་ལ་ཡ་) or 'The Land of Snow' (གངས་ཅན་ལྗོངས་) in Tibetan, the Himāliya Mountain Range (سلسلہ کوہ ہمالیہ) in Urdu, the Himaloy Parvatmala (হিমালয় পর্বতমালা) in Bengali and the Ximalaya Mountain Range (simplified Chinese :喜马拉雅山脉 ; traditional Chinese :喜馬拉雅山脉 ; pinyin :Xǐmǎlāyǎ Shānmài) in Chinese.
The name of the range is sometimes also given as Himavan in older writings.
The Himalayas consist of parallel mountain ranges: the Sivalik Hills on the south; the Lower Himalayan Range; the Great Himalayas, which is the highest and central range; and the Tibetan Himalayas on the north.The Karakoram are generally considered separate from the Himalayas.
In the middle of the great curve of the Himalayan mountains lie the 8,000 m (26,000 ft) peaks of Dhaulagiri and Annapurna in Nepal, separated by the Kali Gandaki Gorge. The gorge splits the Himalayas into Western and Eastern sections both ecologically and orographically – the pass at the head of the Kali Gandaki the Kora La is the lowest point on the ridgeline between Everest and K2 (the highest peak of the Karakoram range). To the east of Annapurna are the 8,000 m (5.0 mi) peaks of Manaslu and across the border in Tibet, Shishapangma. To the south of these lies Kathmandu, the capital of Nepal and the largest city in the Himalayas. East of the Kathmandu Valley lies the valley of the Bhote/Sun Kosi river which rises in Tibet and provides the main overland route between Nepal and China – the Araniko Highway/China National Highway 318. Further east is the Mahalangur Himal with four of the world's six highest mountains, including the highest: Cho Oyu, Everest, Lhotse and Makalu. The Khumbu region, popular for trekking, is found here on the south-western approaches to Everest. The Arun river drains the northern slopes of these mountains, before turning south and flowing to the range to the east of Makalu.
In the far east of Nepal, the Himalayas rise to the Kangchenjunga massif on the border with India, the third highest mountain in the world, the most easterly 8,000 m (26,000 ft) summit and the highest point of India. The eastern side of Kangchenjunga is in the Indian state of Sikkim. Formerly an independent Kingdom, it lies on the main route from India to Lhasa, Tibet, which passes over the Nathu La pass into Tibet. East of Sikkim lies the ancient Buddhist Kingdom of Bhutan. The highest mountain in Bhutan is Gangkhar Puensum, which is also a strong candidate for the highest unclimbed mountain in the world. The Himalayas here are becoming increasingly rugged with heavily forested steep valleys. The Himalayas continue, turning slightly northeast, through the Indian State of Arunachal Pradesh as well as Tibet, before reaching their easterly conclusion in the peak of Namche Barwa, situated in Tibet inside the great bend of the Yarlang Tsangpo river. On the other side of the Tsangpo, to the east, are the Kangri Garpo mountains. The high mountains to the north of the Tsangpo including Gyala Peri, however, are also sometimes included in the Himalayas.
Going west from Dhaulagiri, Western Nepal is somewhat remote and lacks major high mountains, but is home to Rara Lake, the largest lake in Nepal. The Karnali River rises in Tibet but cuts through the centre of the region. Further west, the border with India follows the Sarda River and provides a trade route into China, where on the Tibetan plateau lies the high peak of Gurla Mandhata. Just across Lake Manasarovar from this lies the sacred Mount Kailash in the Kailash Ranges, which stands close to the source of the four main rivers of Himalayas and is revered in Hinduism, Buddhism, Sufism, Jainism, and Bonpo. In the newly created Indian state of Uttarkhand, the Himalayas rise again as the Kumaon Himalayaswith the high peaks of Nanda Devi and Kamet. The state is also home to the important pilgrimage destinations of Chaar Dhaam, with Gangotri, the source of the holy river Ganges, Yamunotri, the source of the river Yamuna, and the temples at Badrinath and Kedarnath. Kumaon Himalayas is regionally divided into 2- Kumaon hills in Kumaon division and Garhwal hills in Garhwal division.
The next Himalayan Indian state, Himachal Pradesh, is noted for its hill stations, particularly Shimla, the summer capital of the British Raj, and Dharmasala, the centre of the Tibetan community and government in exile in India. This area marks the start of the Punjab Himalaya and the Sutlej river, the most easterly of the five tributaries of the Indus, cuts through the range here. Further west, the Himalayas form most of the southern portion of Jammu and Kashmir and Ladakh, which are disputed between India and Pakistan but administered by India. The twin peaks of Nun Kun are the only mountains over 7,000 m (4.3 mi) in this part of the Himalayas. Beyond lies the renowned Kashmir Valley and the town and lakes of Srinagar. Finally, the Himalayas reach their western end in the dramatic 8000 m peak of Nanga Parbat, which rises over 8,000 m (26,000 ft) above the Indus valley and is the most westerly of the 8000 m summits. The western end terminates at a magnificent point near Nanga Parbat where the Himalayas intersect with the Karakoram and Hindu Kush ranges, in the disputed Pakistani-administered territory of Gilgit-Baltistan. Some portion of the Himalayas, such as the Kaghan valley, Margalla hills and Galyat tract, extend into the Pakistani provinces of Khyber Pakhtunkhwa and Punjab.
The Himalayan range is one of the youngest mountain ranges on the planet and consists mostly of uplifted sedimentary and metamorphic rock. According to the modern theory of plate tectonics, its formation is a result of a continental collision or orogeny along the convergent boundary (Main Himalayan Thrust) between the Indo-Australian Plate and the Eurasian Plate. The Arakan Yoma highlands in Myanmar and the Andaman and Nicobar Islands in the Bay of Bengal were also formed as a result of this collision.
During the Upper Cretaceous, about 70 million years ago, the north-moving Indo-Australian Plate (which has subsequently broken into the Indian Plate and the Australian Plate ) was moving at about 15 cm (5.9 in) per year. About 50 million years ago this fast-moving Indo-Australian Plate had completely closed the Tethys Ocean, the existence of which has been determined by sedimentary rocks settled on the ocean floor and the volcanoes that fringed its edges. Since both plates were composed of low density continental crust, they were thrust faulted and folded into mountain ranges rather than subducting into the mantle along an oceanic trench. An often-cited fact used to illustrate this process is that the summit of Mount Everest is made of marine limestone from this ancient ocean.
Today, the Indian plate continues to be driven horizontally at the Tibetan Plateau, which forces the plateau to continue to move upwards. mm per year, and over the next 10 million years it will travel about 1,500 km (930 mi) into Asia. About 20 mm per year of the India-Asia convergence is absorbed by thrusting along the Himalaya southern front. This leads to the Himalayas rising by about 5 mm per year, making them geologically active. The movement of the Indian plate into the Asian plate also makes this region seismically active, leading to earthquakes from time to time.The Indian plate is still moving at 67
During the last ice age, there was a connected ice stream of glaciers between Kangchenjunga in the east and Nanga Parbat in the west. 1,000–2,000 m (3,300–6,600 ft). While the current valley glaciers of the Himalaya reach at most 20 to 32 km (12 to 20 mi) in length, several of the main valley glaciers were 60 to 112 km (37 to 70 mi) long during the ice age. The glacier snowline (the altitude where accumulation and ablation of a glacier are balanced) was about 1,400–1,660 m (4,590–5,450 ft) lower than it is today. Thus, the climate was at least 7.0 to 8.3 °C (12.6 to 14.9 °F) colder than it is today.In the west, the glaciers joined with the ice stream network in the Karakoram, and in the north, they joined with the former Tibetan inland ice. To the south, outflow glaciers came to an end below an elevation of
Despite their scale, the Himalayas do not form a major watershed, and a number of rivers cut through the range, particularly in the eastern part of the range. As a result, the main ridge of the Himalayas is not clearly defined, and mountain passes are not as significant for traversing the range as with other mountain ranges. The rivers of the Himalayas drain into two large river systems:
The northern slopes of Gyala Peri and the peaks beyond the Tsangpo, sometimes included in the Himalayas, drain into the Irrawaddy River, which originates in eastern Tibet and flows south through Myanmar to drain into the Andaman Sea. The Salween, Mekong, Yangtze and Yellow River all originate from parts of the Tibetan Plateau that are geologically distinct from the Himalaya mountains and are therefore not considered true Himalayan rivers. Some geologists refer to all the rivers collectively as the circum-Himalayan rivers.
The great ranges of central Asia, including the Himalayas, contain the third-largest deposit of ice and snow in the world, after Antarctica and the Arctic. 12,000 km3 (2,900 cu mi) of fresh water. Its glaciers include the Gangotri and Yamunotri (Uttarakhand) and Khumbu glaciers (Mount Everest region), Langtang glacier (Langtang region) and Zemu (Sikkim).The Himalayan range encompasses about 15,000 glaciers, which store about
Owing to the mountains' latitude near the Tropic of Cancer, the permanent snow line is among the highest in the world at typically around 5,500 m (18,000 ft). In contrast, equatorial mountains in New Guinea, the Rwenzoris and Colombia have a snow line some 900 m (2,950 ft) lower. The higher regions of the Himalayas are snowbound throughout the year, in spite of their proximity to the tropics, and they form the sources of several large perennial rivers.
In recent years, scientists have monitored a notable increase in the rate of glacier retreat across the region as a result of climate change.For example, glacial lakes have been forming rapidly on the surface of debris-covered glaciers in the Bhutan Himalaya during the last few decades. Although the effect of this will not be known for many years, it potentially could mean disaster for the hundreds of millions of people who rely on the glaciers to feed the rivers during the dry seasons. The global climate change will affect the water resources and livelihoods of the Greater Himalayan region.
The Himalayan region is dotted with hundreds of lakes. 700 km2 (270 sq mi).Pangong Tso, which is spread across the border between India and China, at far western end of Tibet, is among the largest with surface areas of
South of the main range, the lakes are smaller. Tilicho Lake in Nepal in the Annapurna massif is one of the highest lakes in the world. Other notable lakes include Rara Lake in western Nepal, She-Phoksundo Lake in the Shey Phoksundo National Park of Nepal, Gurudongmar Lake, in North Sikkim, Gokyo Lakes in Solukhumbu district of Nepal and Lake Tsongmo, near the Indo-China border in Sikkim.
Some of the lakes present a danger of a glacial lake outburst flood. The Tsho Rolpa glacier lake in the Rowaling Valley, in the Dolakha District of Nepal, is rated as the most dangerous. The lake, which is located at an altitude of 4,580 m (15,030 ft) has grown considerably over the last 50 years due to glacial melting. The mountain lakes are known to geographers as tarns if they are caused by glacial activity. Tarns are found mostly in the upper reaches of the Himalaya, above 5,500 m (18,000 ft).
Temperate Himalayan wetlands provide important habitat and layover sites for migratory birds. Many mid and low altitude lakes remain poorly studied in terms of their hydrology and biodiversity, like Khecheopalri in the Sikkim Eastern Himalayas.
The vast size, huge altitude range, and complex topography of the Himalayas mean they experience a wide range of climates, from humid subtropical in the foothills to cold and dry desert conditions on the Tibetan side of the range. For much of the Himalayas – that on the south side of the high mountains, except in the furthest west, the most characteristic feature of the climate is the monsoon. Heavy rain arrives on the southwest monsoon in June and persists until September. The monsoon can seriously impact transport and cause major landslides. It restricts tourism – the trekking and mountaineering season is limited to either before the monsoon in April/May or after the monsoon in October/November (autumn). In Nepal and Sikkim, there are often considered to be five seasons: summer, monsoon, autumn, (or post-monsoon), winter, and spring.
Using the Köppen climate classification, the lower elevations of the Himalayas, reaching in mid-elevations in central Nepal (including the Kathmandu valley), are classified as Cwa, Humid subtropical climate with dry winters. Higher up, most of the Himalayas have a subtropical highland climate (Cwb).
In the furthest west of the Himalayas, in the west of the Kashmir valley and the Indus valley, the South Asian monsoon is no longer a dominant factor and most precipitation falls in the spring. Srinagar receives around 723 mm (28 in) around half the rainfall of locations such as Shimla and Kathmandu, with the wettest months being March and April.
The northern side of the Himalayas, also known as the Tibetan Himalaya, is dry, cold and generally, wind swept particularly in the west where it has a cold desert climate. The vegetation is sparse and stunted and the winters are severely cold. Most of the precipitation in the region is in the form of snow during the late winter and spring months.
Local impacts on climate are significant throughout the Himalayas. Temperatures fall by 0.2 to 1.2 °C for every 100 m (330 ft) rise in altitude. This gives rise to a variety of climates from a nearly tropical climate in the foothills, to tundra and permanent snow and ice at higher elevations. Local climate is also affected by the topography: The leeward side of the mountains receive less rain while the well exposed slopes get heavy rainfall and the rain shadow of large mountains can be significant, for example leading to near desert conditions in the Upper Mustang which is sheltered from the monsoon rains by the Annapurna and Dhaulagiri massifs and has annual precipitation of around 300 mm (12 in), while Pokhara on the southern side of the massifs has substantial rainfall (3,900 mm or 150 in a year). Thus although annual precipitation is generally higher in east than the west, local variations are often more important.
The Himalayas have a profound effect on the climate of the Indian subcontinent and the Tibetan Plateau. They prevent frigid, dry winds from blowing south into the subcontinent, which keeps South Asia much warmer than corresponding temperate regions in the other continents. It also forms a barrier for the monsoon winds, keeping them from traveling northwards, and causing heavy rainfall in the Terai region. The Himalayas are also believed to play an important part in the formation of Central Asian deserts, such as the Taklamakan and Gobi.
An acceleration of ice loss across the Himalayas over the past 40 years has been proven with satellite photos. °C target would be reached, the Himalaya glaciers would expectedly lose one third of their surfaces.Even if the ambitious 1.5
The flora and fauna of the Himalayas vary 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 altitude, rainfall, and soil conditions combined with the very high snow line supports a variety of distinct plant and animal communities.The extremes of high altitude (low atmospheric pressure) combined with extreme cold favor extremophile organisms.
At high altitudes, the elusive and previously endangered snow leopard is the main predator. Its prey includes members of the goat family grazing on the alpine pastures and living on the rocky terrain, notably the endemic bharal or Himalayan blue sheep. The Himalayan musk deer is also found at high altitudes. Hunted for its musk, it is now rare and endangered. Other endemic or near-endemic herbivores include the Himalayan tahr, the takin, the Himalayan serow, and the Himalayan goral. The critically endangered Himalayan subspecies of the brown bear is found sporadically across the range as is the Asian black bear. In the mountainous mixed deciduous and conifer forests of the eastern Himalayas, Red panda feed in the dense understories of bamboo. Lower down the forests of the foothills are inhabited by several different primates, including the endangered Gee's golden langur and the Kashmir gray langur, with highly restricted ranges in the east and west of the Himalayas respectively.
The unique floral and faunal wealth of the Himalayas is undergoing structural and compositional changes due to climate change. Hydrangea hirta is an example of floral species that can be found in this area. The increase in temperature is shifting various species to higher elevations. The oak forest is being invaded by pine forests in the Garhwal Himalayan region. There are reports of early flowering and fruiting in some tree species, especially rhododendron, apple and box myrtle . The highest known tree species in the Himalayas is Juniperus tibetica located at 4,900 m (16,080 ft) in Southeastern Tibet.
There are many cultural aspects of the Himalayas. In Jainism, Mount Ashtapad in Himalayas is a sacred place where the first Jain Tirthankara, Rishabhdeva attained moksha. It is believed that after Rishabhdeva attained nirvana , his son, Emperor Bharata Chakravartin, had constructed three stupas and twenty four shrines of the 24 Tirthankaras with their idols studded with precious stones over there and named it Sinhnishdha.For the Hindus, the Himalayas are personified as Himavath, the father of the goddess Parvati. The Himalayas is also considered to be the father of the river Ganges. Two of the most sacred places of pilgrimage for the Hindus is the temple complex in Pashupatinath and Muktinath, also known as Saligrama because of the presence of the sacred black rocks called saligrams.
The Buddhists also lay a great deal of importance on the Himalayas. Paro Taktsang is the holy place where Buddhism started in Bhutan.The Muktinath is also a place of pilgrimage for the Tibetan Buddhists. They believe that the trees in the poplar grove came from the walking sticks of eighty-four ancient Indian Buddhist magicians or mahasiddhas. They consider the saligrams to be representatives of the Tibetan serpent deity known as Gawo Jagpa. The Himalayan people's diversity shows in many different ways. It shows through their architecture, their languages, and dialects, their beliefs and rituals, as well as their clothing. The shapes and materials of the people's homes reflect their practical needs and beliefs. Another example of the diversity amongst the Himalayan peoples is that handwoven textiles display colors and patterns unique to their ethnic backgrounds. Finally, some people place great importance on jewelry. The Rai and Limbu women wear big gold earrings and nose rings to show their wealth through their jewelry. Several places in the Himalayas are of religious significance in Hinduism, Buddhism, Jainism and Sikhism. A notable example of a religious site is Paro Taktsang, where Padmasambhava is said to have founded Buddhism in Bhutan.
In Hinduism, the Himalayas have been personified as the king of all Mountain – "Giriraj Himavat", father of Ganga and Parvati (form of Adi Shakti Durga).
A number of Vajrayana Buddhist sites are situated in the Himalayas, in Tibet, Bhutan and in the Indian regions of Ladakh, Sikkim, Arunachal Pradesh, Spiti and Darjeeling. There were over 6,000 monasteries in Tibet, including the residence of the Dalai Lama.Bhutan, Sikkim and Ladakh are also dotted with numerous monasteries.
The Himalayas are home to a diversity of medicinal resources. Plants from the forests have been used for millennia to treat conditions ranging from simple coughs to snake bites.Different parts of the plants – root, flower, stem, leaves, and bark – are used as remedies for different ailments. For example, a bark extract from an abies pindrow tree is used to treat coughs and bronchitis. Leaf and stem paste from an arachne cordifolia is used for wounds and as an antidote for snake bites. The bark of a callicarpa arborea is used for skin ailments. Nearly a fifth of the gymnosperms, angiosperms and pteridophytes in the Himalayas are found to have medicinal properties, and more are likely to be discovered.
Most of the population in some Asian and African countries depend on medicinal plants rather than prescriptions and such.Since so many people use medicinal plants as their only source of healing in the Himalayas, the plants are an important source of income. This contributes to economic and modern industrial development both inside and outside the region. The only problem is that locals are rapidly clearing the forests on the Himalayas for wood, often illegally.
India is situated north of the equator between 8°4' north to 37°6' north latitude and 68°7' east to 97°25' east longitude. It is the seventh-largest country in the world, with a total area of 3,287,263 square kilometres (1,269,219 sq mi). India measures 3,214 km (1,997 mi) from north to south and 2,933 km (1,822 mi) from east to west. It has a land frontier of 15,200 km (9,445 mi) and a coastline of 7,516.6 km (4,671 mi).
Kangchenjunga, also spelled Kanchenjunga, is the third highest mountain in the world. It rises with an elevation of 8,586 m (28,169 ft) in a section of the Himalayas called Kangchenjunga Himal delimited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River. It lies between India and Nepal, with three of the five peaks, namely Main, Central and South, directly on the border, and the peaks West and Kangbachen in Nepal's Taplejung District.
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 Kingdom of Bhutan is a sovereign nation, located towards the eastern extreme of the Himalayas mountain range. It is fairly evenly sandwiched between the sovereign territory of two nations: first, the People's Republic of China on the north and northwest. There are approximately 477 kilometres of border with that nation's Tibet Autonomous Region. The second nation is the Republic of India on the south, southwest, and east; there are approximately 659 kilometres with the states of Arunachal Pradesh, Assam, West Bengal, and Sikkim, in clockwise order from the kingdom. Bhutan's total borders amount to 1,139 kilometres. The Republic of Nepal to the west, the People's Republic of Bangladesh to the south, and the Union of Myanmar to the southeast are other close neighbours; the former two are separated by only very small stretches of Indian territory.
The Karakoram is a mountain range spanning the borders of China, India, and Pakistan, with the northwest extremity of the range extending to Afghanistan and Tajikistan; its highest 15 mountains are all based in Pakistan. It begins in the Wakhan Corridor (Afghanistan) in the west, encompasses the majority of Gilgit-Baltistan, and extends into Ladakh and Aksai Chin. It is the second highest mountain range in the world and part of the complex of ranges including the Pamir Mountains, the Hindu Kush and the Himalayan Mountains. The Karakoram has eighteen summits over 7,500 m (24,600 ft) height, with four of them exceeding 8,000 m (26,000 ft): K2, the second highest peak in the world at 8,611 m (28,251 ft), Gasherbrum I, Broad Peak and Gasherbrum II.
The geography of Tibet consists of the high mountains, lakes and rivers lying between Central, East and South Asia. Traditionally, Western sources have regarded Tibet as being in Central Asia, though today's maps show a trend toward considering all of modern China, including Tibet, to be part of East Asia. Tibet is often called "the roof of the world," comprising tablelands averaging over 4,950 metres above the sea with peaks at 6,000 to 7,500 m, including Mount Everest, on the border with Nepal.
The Tibetan Plateau, also known as the Qinghai–Tibet Plateau or the Qing–Zang Plateau or as the Himalayan Plateau in India, is a vast elevated plateau in Central Asia and East Asia, covering most of the Tibet Autonomous Region, most of Qinghai, Northwestern Yunnan, Western half of Sichuan, Southern Gansu provinces in Western China, the Indian regions of Ladakh and Lahaul and Spiti as well as Bhutan. It stretches approximately 1,000 kilometres (620 mi) north to south and 2,500 kilometres (1,600 mi) east to west. It is the world's highest and largest plateau above sea level, with an area of 2,500,000 square kilometres (970,000 sq mi). With an average elevation exceeding 4,500 metres (14,800 ft) and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is often referred to as "the Roof of the World".
Rolwāling Valley , knows as a (Gaurishankar) rural municipality, is a section of the Himalayas in east-central Nepal along the Tibet border. Rolwaling Himal includes Melungtse 7181m and Melungtse II 7023m inside Tibet and Gaurishankar 7134m on the Nepal border with some 50 additional peaks over 6000m, all extending from the Nangpa La pass where the Mahalangur section begins, southwest to the Tamakosi River. The Labuche Himal section rises beyond the Tamakosi to the northwest. Rolwaling Himal is bounded on the south by the Rolwaling Valley which contain several small sherpa villages Tasi Nam, Simigau and Beding under rolwaling valley, Tasi Nam is the largest town of the area. Five to six days are required to reach Namche Bazaar after Tasilapcha pass. Visitors can trek to Everest base camp by crossing Tasilapcha or fly from Kathmandu to Lukla.
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 east.
The Great Himalayas or Greater Himalayas or Himadri is the highest mountain range of the Himalayan Range. The world's highest peak, Mount Everest, as well as other "near−highest" peaks, such as Kangchenjunga, Lhotse, and Nanga Parbat, are part of the Greater Himalayas range. The total west to east extension of the Great Himalayas is 2400 km and their average elevation is 6000 m (20000 ft.).
The Nyenchen Tanglha Mountains are a 700-kilometre (430 mi) long mountain range, and subrange of the Transhimalaya System, located in the Tibet region and the Tibet Autonomous Region of China.
The Arun River is a trans-boundary river and is part of the Kosi or Sapt Koshi river system in Nepal. It originates in Tibet Autonomous Region of the People's Republic of China where it is called the Phung Chu or Bum-chu.
The Eastern Himalayas extend from eastern Nepal across Northeast India, Bhutan, the Tibet Autonomous Region to Yunnan in China and northern Myanmar. The climate of this region is influenced by the monsoon of South Asia from June to September. It is a biodiversity hotspot, with notable biocultural diversity.
The Great Himalaya Trail is a route across the Himalayas from east to west. The original concept of the trail was to establish a single long distance trekking trail from the east end to the west end of Nepal that includes a total of roughly 1,700 kilometres (1,100 mi) of path. There is a proposed trail of more than 4,500 kilometres (2,800 mi) stretching the length of the Greater Himalaya range from Nanga Parbat in Pakistan to Namche Barwa in Tibet thus passing through, India, Nepal, Bhutan and Tibet. Although an actual continuous route is currently only a concept, if completed it would be the longest and highest alpine hiking track in the world.
Noijin Kangsang is the highest peak of Lhagoi Kangri mountain range in the Tibet Autonomous Region in China. It lies between the Yarlung Tsangpo River, Yamdrok Lake and the Himalayas mountain range.
The mountains of Bhutan are some of the most prominent natural geographic features of the kingdom. Located on the southern end of the Eastern Himalaya, Bhutan has one of the most rugged mountain terrains in the world, whose elevations range from 160 metres (520 ft) to more than 7,000 metres (23,000 ft) above sea level, in some cases within distances of less than 100 kilometres (62 mi) of each other. Bhutan's highest peak, at 7,570 metres (24,840 ft) above sea level, is north-central Gangkhar Puensum, close to the border with China; the third highest peak, Jomolhari, overlooking the Chumbi Valley in the west, is 7,314 metres (23,996 ft) above sea level; nineteen other peaks exceed 7,000 metres (23,000 ft). Weather is extreme in the mountains: the high peaks have perpetual snow, and the lesser mountains and hewn gorges have high winds all year round, making them barren brown wind tunnels in summer, and frozen wastelands in winter. The blizzards generated in the north each winter often drift southward into the central highlands.
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
High-Mountain Asia (HMA) is a high-elevation geographic region in Asia that includes numerous cordillera and highland systems around the Tibetan Plateau, encompassing regions of East, Southeast, Central and South Asia. The region was orogenically formed by the continental collision of the Indian Plate into the Eurasian Plate.
Kangri Karpo, also spelt Gangri Garbo, is a mountain range in eastern Tibet, located primarily in Nyingchi Prefecture as well as a portion of Qamdo Prefecture in the Tibet Autonomous Region, China. The mountain range lies to the east of the Himalayas and to the west of the Hengduan Mountains. The mountains are geographically a southern extension of the eastern Transhimalayas.
