The Himalayan range has many of the Earth's highest peaks, including the highest, Mount Everest. The Himalayas include over fifty mountains exceeding 7,200 m (23,600 ft) in elevation, including ten of the fourteen 8,000-metre peaks. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is 6,961 m (22,838 ft) tall.
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 Indus river. Its eastern anchor, Namcha Barwa, is just west of the great bend of the Yarlung Tsangpo River (upper stream of the Brahmaputra River). The Himalayan range is bordered on the northwest by the Karakoram and the Hindu Kush ranges. To the north, the chain is separated from the Tibetan Plateau by a 50–60 km (31–37 mi) wide tectonic valley called the Indus-Tsangpo Suture. Towards the south the arc of the Himalaya is ringed by the very low Indo-Gangetic Plain. The range varies in width from 350 km (220 mi) in the west (Pakistan) to 150 km (93 mi) in the east (Arunachal Pradesh). The Himalayas are distinct from the other great ranges of central Asia, although sometimes the term 'Himalaya' (or 'Greater Himalaya') is loosely used to include the Karakoram and some of the other ranges.
The Himalayas are inhabited by 52.7 million people, and are spread across five countries: Nepal, India, Bhutan, China and Pakistan. Some of the world's major rivers — the Indus, the Ganges and the Tsangpo-Brahmaputra — rise in the Himalayas, and their combined drainage basin is home to roughly 600 million people. The Himalayas have a profound effect on the climate of the region, helping to keep the monsoon rains on the Indian plain and limiting rainfall on the Tibetan plateau. The Himalayas have profoundly shaped the cultures of the Indian subcontinent; many Himalayan peaks are sacred in Hinduism and Buddhism.

The general location of the Himalayas mountain range (this map has the Hindu Kush in the Himalaya, not normally regarded as part of the core Himalayas).
The name of the range derives from the Sanskrit Himā-laya (हिमालय, "Abode of Snow"), from himá (हिम, "snow") and ā-laya (आलय, "receptacle, dwelling"). They are now known as the "Himalaya Mountains", usually shortened to the "Himalayas". Formerly, they were described in the singular as the Himalaya. This was also previously transcribed 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), the Himalaya (ཧི་མ་ལ་ཡ་) or 'The Land of Snow' (གངས་ཅན་ལྗོངས་) in Tibetan, the Hamaleh Mountain Range (Urdu: سلسلہ کوہ ہمالیہ) in Urdu and the Ximalaya Mountain Range (Chinese: 喜馬拉雅山脈; pinyin: Xǐmǎlāyǎ Shānmài) in Chinese.
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. 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 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 through the range to the east of Makalu.
In the far east of Nepal, the Himalayas rise to the Kanchenjunga 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 Kanchenjunga 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 also 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 center 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, 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 Garhwal Himalayas with the high peaks of Nanda Devi and Kamet. The state is also an important pilgrimage destination, with the source of the Ganges at Gangotri and the Yamuna at Yamunotri, and the temples at Badrinath and Kedarnath.
The next Himalayan Indian state, Himachal Pradesh, it is noted for its hill stations, particularly Shimla, the summer capital of the British Raj, and Dharmasala, the centre of the Tibetan community 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 the Indian State of Jammu & Kashmir. 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 renown Kashmir Valley and the town and lakes of Srinagar. Finally, the Himalayas cross the Line of Control into Pakistan and reach their western end in the dramatic 8000 m peak of Nanga Parbat, which rises over 7,000 m (23,000 ft) above the Indus valley and is the most westerly of the 8000 m summits.
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 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. The Indian plate is still moving at 67 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.
During the last ice age, there was a connected ice stream of glaciers between Kangchenjunga in the east and Nanga Parbat in the west. 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 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.
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. The Himalayan range encompasses about 15,000 glaciers, which store about 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).
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 global 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 Himalayan region is dotted with hundreds of lakes. Most of the larger lakes are on the northern side of the main range. The most famous is the sacred freshwater Lake Manasarovar, near to Mount Kailas with an area of 410 km2 (160 sq mi) and an altitude of 4,590 m (15,060 ft). It drains into the nearby Lake Rakshastal with an area of 250 km2 (97 sq mi) and slightly lower at 4,575 m (15,010 ft). Pangong Tso, which is spread across the border between India and China, at far western end of Tibet, and Yamdrok Tso, located in south central Tibet, are among the largest with surface areas of 700 km2 (270 sq mi), and 638 km2 (246 sq mi), respectively. Lake Puma Yumco is one of the highest of the larger lakes at an elevation of 5,030 m (16,500 ft).
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).
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, dry desert conditions on the Tibetan side of the range. For much of 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 south-west 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 late winter and spring months.
Local impacts on climate are significant throughout the Himalayas. Temperatures fall by 6.5 °C (11.7 °F) for every 1,000 m (3,300 ft) rise in altitude. This gives rise to a variety of climates from nearly tropical in the foothills to tundra and permanent snow and ice. 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.
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 altitude. 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.
The Himalayan population belongs to four distinct cultural groups, who throughout history have systematically penetrated the isolated indigenous Himalayan population. Those migrating cultures – Hindu (Indian), Buddhist (Tibetan), Islamic (Afghanistan–Iranian) and Animist (Burmese and southeast Asian) – have created here their own individual and unique place. Their current arrangement, though with a few exceptions, is linked to specific geographical regions, and the relative altitude at which they occur.
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 mountains of 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 the 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 a great importance on jewellery. The Rai and Limbu women wear big gold earrings and nose rings to show their wealth through their jewellery.
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. Padmasambhava is also worshipped as the patron saint of Sikkim. There are also Muslim and Hindhu Shaivite Kashmiri Pandit in the area of Kashmir.
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 Tibetan Muslims have their own mosques in Lhasa and Shigatse.
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. This means that the number of medicinal plants is declining and that some of them might become rarer or, in some cases, go extinct.
Although locals are clearing out portions of the forests in the Himalayas, there is still a large amount of greenery ranging from the tropical forests to the Alpine forests. These forests provide wood for fuel and other raw materials for use by industries. There are also many pastures for animals to graze upon. The many varieties of animals that live in these mountains do so based on the elevation. For example, elephants and rhinoceros live in the lower elevations of the Himalayas, also called the Terai region. Also, found in these mountains are the Kashmiri stag, black bears, musk deer, langur, and snow leopards. The Tibetan yak are also found on these mountains and are often used by the people for transportation. However, the populations of many of these animals and still others are declining and are on the verge of going extinct.
The Himalayas are also a source of many minerals and precious stones. Amongst the tertiary rocks, are vast potentials of mineral oil. There is coal located in Kashmir, and precious stones located in the Himalayas. There is also gold, silver, copper, zinc, and many other such minerals and metals located in at least 100 different places in these mountains.
Annapurna (Sanskrit, Nepali, Newar: अन्नपूर्णा) is a massif in the Himalayas in north-central Nepal that includes one peak over 8,000 metres (26,000 ft), thirteen peaks over 7,000 metres (23,000 ft), and sixteen more over 6,000 metres (20,000 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 Pokhara Valley on the south. At the western end the massif encloses a high basin called the Annapurna Sanctuary. Annapurna I Main is the tenth highest mountain in the world at 8,091 metres (26,545 ft) above sea level, and was the first of the Eight-thousanders to be climbed.
The entire massif and surrounding area are protected within the 7,629 square kilometres (2,946 sq mi) Annapurna Conservation Area, the first and largest conservation area in Nepal. The Annapurna Conservation Area is home to several world-class treks, including Annapurna Sanctuary and Annapurna Circuit.
Historically, the Annapurna peaks are among the world's most dangerous mountains to climb, although in more recent history, using only figures from 1990 and after, Kangchenjunga has a higher fatality rate. By March 2012, there had been 191 summit ascents of Annapurna I Main, and 61 climbing fatalities on the mountain. This fatality-to-summit ratio (32%) is the highest of any of the eight-thousanders. In particular, the ascent via the south face is considered, by some, the most difficult of all climbs. In October 2014, at least 43 people were killed as a result of snowstorms and avalanches on and around Annapurna, in Nepal's worst ever trekking disaster.Annapurna is a female Sanskrit name that literally means "(She who is) Replete with food", but is normally translated as Goddess of the Harvests. According to Devdutt Pattanaik, Annapoorna devi is "... the universal and timeless kitchen-goddess ... the mother who feeds. Without her there is starvation, a universal fear: This makes Annapurna a universal goddess ... Her most popular shrine is located in Varanasi, on the banks of the Ganges River." Her association with the giving of food (wealth) led her in time to be transformed into Lakshmi, the Goddess of Wealth.Bharal
The bharal (Pseudois nayaur), also called the Himalayan blue sheep or naur, is a caprid found in the high Himalayas of India, Nepal, Bhutan, Tibet, Myanmar and Pakistan. Its native names include bharal, barhal, bharar and bharut in Hindi, na or sna in Ladakh, nabo in Spitian, naur in Nepali and na or gnao in Bhutan.
The bharal was also the focus of George Schaller's and Peter Matthiessen's expedition to Nepal in 1973. Their personal experiences are well documented by Matthiessen in his book, The Snow Leopard. The bharal is a major food of the snow leopard.Brahmaputra River
The Brahmaputra () is one of the major rivers of Asia, a trans-boundary river which flows through China, India and Bangladesh. As such, it is known by various names in the region: Assamese: লুইত luit [luɪt], ব্ৰহ্মপুত্ৰ নৈ Brohmoputro noi, ব্ৰহ্মপুত্ৰ নদ (the tatsama 'নদ' nod, masculine form of the tatsama 'নদী' nodi "river") Brohmoputro [bɹɔɦmɔputɹɔ]; Sanskrit: ब्रह्मपुत्र, IAST: Brahmaputra; Tibetan: ཡར་ཀླུངས་གཙང་པོ་, Wylie: yar klung gtsang po Yarlung Tsangpo; simplified Chinese: 布拉马普特拉河; traditional Chinese: 布拉馬普特拉河; pinyin: Bùlāmǎpǔtèlā Hé. It is also called Tsangpo-Brahmaputra (when referring to the whole river including the stretch within Tibet). The Manas River, which runs through Bhutan, joins it at Jogighopa, in India. It is the ninth largest river in the world by discharge, and the 15th longest.
With its origin in the Manasarovar Lake region, located on the northern side of the Himalayas in Burang County of Tibet as the Yarlung Tsangpo River, it flows across southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh (India). It flows southwest through the Assam Valley as Brahmaputra and south through Bangladesh as the Jamuna (not to be mistaken with Yamuna of India). In the vast Ganges Delta, it merges with the Padma, the popular name of the river Ganges in Bangladesh, and finally the Meghna and from here it is known as Meghna before emptying into the Bay of Bengal.About 2,899.9 km (1,801.9 mi) long, the Brahmaputra is an important river for irrigation and transportation. The average depth of the river is 38 m (124 ft) and maximum depth is 120 m (380 ft). The river is prone to catastrophic flooding in the spring when Himalayas snow melts. The average discharge of the river is about 19,800 m3/s (700,000 cu ft/s), and floods can reach over 100,000 m3/s (3,500,000 cu ft/s). It is a classic example of a braided river and is highly susceptible to channel migration and avulsion. It is also one of the few rivers in the world that exhibit a tidal bore. It is navigable for most of its length.
The river drains the Himalaya east of the Indo-Nepal border, south-central portion of the Tibetan plateau above the Ganga basin, south-eastern portion of Tibet, the Patkai-Bum hills, the northern slopes of the Meghalaya hills, the Assam plains, and the northern portion of Bangladesh. The basin, especially south of Tibet, is characterized by high levels of rainfall. Kangchenjunga (8,586 m) is the only peak above 8,000 m, hence is the highest point within the Brahmaputra basin.
The Brahmaputra's upper course was long unknown, and its identity with the Yarlung Tsangpo was only established by exploration in 1884–86. This river is often called the Tsangpo-Brahmaputra river.
The lower reaches are sacred to Hindus. While most rivers on the Indian subcontinent have female names, this river has a rare male name, as it means "son of Brahma" in Sanskrit (putra means "son").Cedrus
Cedrus (common English name cedar) is a genus of coniferous trees in the plant family Pinaceae (subfamily Abietoideae). They are native to the mountains of the western Himalayas and the Mediterranean region, occurring at altitudes of 1,500–3,200 m in the Himalayas and 1,000–2,200 m in the Mediterranean.Climate of India
The Climate of India comprises a wide range of weather conditions across a vast geographic scale and varied topography, making generalisations difficult. Based on the Köppen system, India hosts six major climatic subtypes, ranging from arid desert in the west, alpine tundra and glaciers in the north, and humid tropical regions supporting rainforests in the southwest and the island territories. Many regions have starkly different microclimates. The country's meteorological department follows the international standard of four climatological seasons with some local adjustments: winter (December, January and February), summer (March, April and May), a monsoon rainy season (June to September), and a post-monsoon period (October to November).
India's geography and geology are climatically pivotal: the Thar Desert in the northwest and the Himalayas in the north work in tandem to effect a culturally and economically important monsoonal regime. As Earth's highest and most massive mountain range, the Himalayas bar the influx of frigid katabatic winds from the icy Tibetan Plateau and northerly Central Asia. Most of North India is thus kept warm or is only mildly chilly or cold during winter; the same thermal dam keeps most regions in India hot in summer.
Though the Tropic of Cancer—the boundary between the tropics and subtropics—passes through the middle of India, the bulk of the country can be regarded as climatically tropical. As in much of the tropics, monsoonal and other weather patterns in India can be wildly unstable: epochal droughts, floods, cyclones, and other natural disasters are sporadic, but have displaced or ended millions of human lives. There is one scientific opinion which states that in South Asia such climatic events are likely to change in unpredictability, frequency, and severity. Ongoing and future vegetative changes and current sea level rises and the attendant inundation of India's low-lying coastal areas are other impacts, current or predicted, that are attributable to global warming.Digital Himalaya
The Digital Himalaya is a project that was founded in December 2000 by Alan Macfarlane and Mark Turin. The main purpose of the project is to preserve old digital materials near the Himalayas, such as photographs, recordings, and journals, and make those resources available over the internet and on DVD.Eastern Himalaya
The Eastern Himalayas extend from eastern Nepal across northeastern 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 widely considered a biodiversity hotspot, with notable biocultural diversity.Eight-thousander
The International Mountaineering and Climbing Federation or UIAA recognise eight-thousanders as the 14 mountains that are more than 8,000 metres (26,247 ft) in height above sea level, and are considered to be sufficiently independent from neighbouring peaks. However, there is no precise definition of the criteria used to assess independence and since 2012, the UIAA has been involved in a process to consider whether the list should be expanded to 20 mountains. All eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits are in the death zone.
The first person to summit all 14 eight-thousanders was Italian Reinhold Messner in 1986, who completed the feat without the aid of supplementary oxygen. In 2010, Spaniard Edurne Pasaban became the first woman to summit all 14 eight-thousanders, but with the aid of supplementary oxygen; in 2011 Austrian Gerlinde Kaltenbrunner became the first woman to summit all 14 eight-thousanders without the aid of supplementary oxygen. From 1950–1964, all eight-thousanders were summited. As of February 2019, K2 remains the only eight-thousander not summited in a Winter ascent.Geography of India
India lies on the Indian Plate, the northern portion of the Indo-Australian Plate, whose continental crust forms the Indian subcontinent. The country is situated north of the equator between 8°04' to 37°06' north latitude and 68°07' 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).On the south, India projects into and is bounded by the Indian Ocean—in particular, by the Arabian Sea on the west, the Lakshadweep Sea to the southwest, the Bay of Bengal on the east, and the Indian Ocean proper to the South . The Palk Strait and Gulf of Mannar separate India from Sri Lanka to its immediate southeast, and the Maldives are some 125 kilometres (78 mi) to the south of India's Lakshadweep Islands across the Eight Degree Channel. India's Andaman and Nicobar Islands, some 1,200 kilometres (750 mi) southeast of the mainland, share maritime borders with Myanmar, Thailand and Indonesia. Kanyakumari at 8°4′41″N and 77°55′230″E is the southernmost tip of the Indian mainland, while the southernmost point in India is Indira Point on Great Nicobar Island. The northernmost point which is under Indian administration is Indira Col, Siachen Glacier. India's territorial waters extend into the sea to a distance of 12 nautical miles (13.8 mi; 22.2 km) from the coast baseline.The northern frontiers of India are defined largely by the Himalayan mountain range, where the country borders China, Bhutan, and Nepal. Its western border with Pakistan lies in the Karakoram range, Punjab Plains, the Thar Desert and the Rann of Kutch salt marshes. In the far northeast, the Chin Hills and Kachin Hills, deeply forested mountainous regions, separate India from Burma. On the east, its border with Bangladesh is largely defined by the Khasi Hills and Mizo Hills, and the watershed region of the Indo-Gangetic Plain.The Ganga is the longest river originating in India. The Ganga–Brahmaputra system occupies most of northern, central, and eastern India, while the Deccan Plateau occupies most of southern India. K2, in the Indian state of Jammu and Kashmir, is the highest point in India at 8,611 m (28,251 ft) and the world's 2nd highest peak. Climate across India ranges from equatorial in the far south, to alpine and tundra in the upper reaches of the Himalayas. the geographic view of India is pretty expository and vivid in the terms of area, mountains and relief.Indian subcontinent
The Indian subcontinent is a southern region and peninsula of Asia, mostly situated on the Indian Plate and projecting southwards into the Indian Ocean from the Himalayas. Geologically, the Indian subcontinent is related to the land mass that rifted from Gondwana and merged with the Eurasian plate nearly 55 million years ago. Geographically, it is the peninsular region in south-central Asia delineated by the Himalayas in the north, the Hindu Kush in the west, and the Arakanese in the east. Politically, the Indian subcontinent includes Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka.Sometimes, the geographical term 'Indian subcontinent' is used interchangeably with 'South Asia', although that last term is used typically as a political term and is also used to include Afghanistan. Which countries should be included in either of these remains the subject of debate.Kangchenjunga
Kangchenjunga, also spelled Kanchenjunga, is the third highest mountain in the world. It lies between Nepal and Sikkim, India, with three of the five peaks (Main, Central and South) directly on the border, and the remaining two (West and Kangbachen) in Nepal's Taplejung District. 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.Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations based on various readings and measurements made by the Great Trigonometrical Survey of India in 1849 came to the conclusion that Mount Everest, known as Peak XV at the time, was the highest. Allowing for further verification of all calculations, it was officially announced in 1856 that Kangchenjunga is the third highest mountain in the world.Kangchenjunga was first climbed on 25 May 1955 by Joe Brown and George Band, who were part of a British expedition. They stopped short of the summit in accordance with the promise given to the Chogyal that the top of the mountain would remain intact. Every climber or climbing group that has reached the summit has followed this tradition. Other members of this expedition included John Angelo Jackson and Tom Mackinon.Karakoram
The Karakoram or Karakorum is a large mountain range spanning the borders of Pakistan, India, and China, with the northwest extremity of the range extending to Afghanistan and Tajikistan. It begins in the Wakhan Corridor (Afghanistan) in the west and encompasses the majority of Gilgit–Baltistan (Pakistan) and extends into Ladakh (India), and the disputed Aksai Chin region controlled by China. 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 eight 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 range is about 500 km (311 mi) in length, and is the most heavily glaciated part of the world outside the polar regions. The Siachen Glacier at 76 kilometres (47 mi) and the Biafo Glacier at 63 kilometres (39 mi) rank as the world's second and third longest glaciers outside the polar regions.The Karakoram is bounded on the east by the Aksai Chin plateau, on the northeast by the edge of the Tibetan Plateau, and on the north by the river valleys of the Yarkand and Karakash rivers beyond which lie the Kunlun Mountains. At the northwest corner are the Pamir Mountains. The southern boundary of the Karakoram is formed, west to east, by the Gilgit, Indus, and Shyok rivers, which separate the range from the northwestern end of the Himalaya range proper. These rivers flow northwest before making an abrupt turn southwestward towards the plains of Pakistan. Roughly in the middle of the Karakoram range is the Karakoram Pass, which was part of a historic trade route between Ladakh and Yarkand but now inactive.
The Tashkurghan National Nature Reserve and the Pamir Wetlands National Nature Reserve in the Karalorun and Pamir mountains have been nominated for inclusion in UNESCO in 2010 by the National Commission of the People's Republic of China for UNESCO and has tentatively been added to the list.Karoh Peak
Karoh Peak is a 1,467-metre (4,813 ft) tall mountain peak in the Sivalik Hills range of greater Himalayas range located near Morni Hills area of Panchkula district, Haryana, India. It is highest point in the state of HaryanaList of glaciers of India
Himalayan region of India is home of some of the most notable glaciers in the world. This is a list of the notable glaciers in India. Most glaciers lie in the states of Sikkim, Jammu and Kashmir, Himachal Pradesh and Uttarakhand.
Few glaciers are also found in Arunachal Pradesh.List of mountains in Nepal
Nepal contains part of the Himalayas, the highest mountain range in the world. Eight of the fourteen eight-thousanders are located in the country, either in whole or shared across a border with China or India. Nepal has the highest mountain in the world, Mount Everest.Nanga Parbat
Nanga Parbat (Urdu: نانگا پربت [naːŋɡaː pərbət̪]), locally known as Diamer (دیامر), is the ninth highest mountain in the world at 8,126 metres (26,660 ft) above sea level. Located in the Diamer District of Pakistan’s Gilgit Baltistan region, Nanga Parbat is the western anchor of the Himalayas. The name Nanga Parbat is derived from the Sanskrit words nagna and parvata which together mean "Naked Mountain". The mountain is locally known by its Tibetan name Diamer or Deo Mir, meaning "huge mountain".Nanga Parbat is one of the eight-thousanders. An immense, dramatic peak rising far above its surrounding terrain, Nanga Parbat is also a notoriously difficult climb. Numerous mountaineering deaths in the mid and early-20th century lent it the nickname "Killer Mountain.”Pir Panjal Range
The Pir Panjal Range (Kashmiri: Pīr Pantsāl Range) is a group of mountains in the Inner Himalayan region, running from east-southeast (ESE) to west-northwest (WNW) across the Indian states of Himachal Pradesh and Jammu and Kashmir where the average elevation varies from 1,400 m (4,600 ft) to 4,100 m (13,500 ft). The Himalayas show a gradual elevation towards the Dhauldhar and Pir Panjal ranges. Pir Panjal is the largest range of the lower Himalayas. Near the bank of the Sutlej river, it dissociates itself from the Himalayas and forms a divide between the rivers Beas and Ravi on one side and the Chenab on the other. The renowned Galyat mountains are also located in this range.Sivalik Hills
The Sivalik Hills, also known as Churia Hills, are a mountain range of the outer Himalayas that stretches from the Indus River about 2,400 km (1,500 mi) eastwards close to the Brahmaputra River. It is 10–50 km (6.2–31.1 mi) wide with an average altitude of 1,500–2,000 m (4,900–6,600 ft). Between the Teesta and Raidāk Rivers in Assam is a gap of about 90 km (56 mi). In some Sanskrit texts, the region is called Manak Parbat. Sivalik literally means 'tresses of Shiva’.The Abominable Snowman (film)
The Abominable Snowman (US title: The Abominable Snowman of the Himalayas) is a 1957 British fantasy-horror film, scripted by Nigel Kneale and based on Kneale's BBC teleplay, "The Creature". It was produced by Hammer Film Productions and directed by Val Guest. The plot follows the exploits of a British scientist (Peter Cushing) who joins an American expedition led by glory-seeker (Forrest Tucker) to search the Himalayas for the legendary Yeti. Maureen Connell, Richard Wattis and Arnold Marle appear in supporting roles.
