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).
The Himalayas, or Himalaya ; Sanskrit: IPA: [ɦɪmɐːləjɐː], himá and ā-laya, are a mountain range in South and East Asia separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has many of Earth's highest peaks, including the highest, Mount Everest, at the border between Nepal and China. 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 is 6,961 m (22,838 ft) tall.
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 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 Yarlung Tsangpo Grand Canyon, also known as the Yarlung Zangbo Grand Canyon, the Tsangpo Canyon, the Brahmaputra Canyon or the Tsangpo Gorge (simplified Chinese: 雅鲁藏布大峡谷; traditional Chinese: 雅魯藏布大峽谷; pinyin: Yǎlǔzàngbù Dàxiágǔ', 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 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, 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 as the gorge bends around Mount Namcha Barwa and cuts its way through the eastern Himalayan range. Its waters drop from about 2,900 metres near Pei to about 1,500 metres 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. The river then enters Arunachal Pradesh and eventually becomes the Brahmaputra.
The Sivalik 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, spanning across the northern parts of the Indian subcontinent. It is 10–50 km (6.2–31.1 mi) wide with an average elevation 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). Sivalik literally means 'tresses of Shiva’. Sivalik region is home to the Soanian archaeological culture.
The Dooars or Duars are the alluvial floodplains in eastern-northeastern India that lie south of the outer foothills of the Himalayas and north of the Brahmaputra River basin. This region is about 30 km (19 mi) wide and stretches over about 350 km (220 mi) from the Teesta River in West Bengal to the Dhansiri River in Assam. The region forms the gateway to Bhutan. It is part of the Terai-Duar savanna and grasslands ecoregion.
Namcha Barwa or Namchabarwa is a mountain peak in the Assam Himalaya that lies in Tibet in the historical 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.
Mangde Chhu or Tongsa river flows in central Bhutan traversing roughly north-south. The river rises in Wangdue Phodrang district, near Gangkhar Puensum, Bhutan's highest peak at 7,546 metres (24,757 ft). Bhutan's main east-west highway crosses the Mangde Chhu about 8 kilometres (5 mi) west of Trongsa. South of Trongsa, the river drains the eastern slopes of the Black Mountains (Bhutan), and forms the eastern boundaries of Black Mountain National Park and Royal Manas National Park. Another highway follows the river south from Trongsa to Shemgang. The highway leaves the river at Tingtinbi, and eventually reaches the Indian border at Gelegphug. South of Tingtinbi, the Mangde is joined by the Bumthang River from the east, and is known as the Tongasa. Shortly before entering India in Assam, the Manas River flows into the river from the east, and the river exits Bhutan near Manas.
Gyala Peri is a 7,294-metre (23,930 ft) peak just beyond the eastern end of the Himalayas at the entrance to Tsangpo gorge. It is part of Nyenchen Tanglha Shan, although it is sometimes included in Namcha Barwa Himal of the Himalayas.
Mêdog, or Metok, or Motuo County, also known as Pemako, is a county as well as a traditional region of the prefecture-level city of Nyingchi in the Tibet Autonomous Region of the People's Republic of China (PRC). Pemako is considered famous as the Nyingma master Dudjom Rinpoche's birthplace, and as a prophesied refuge for Tibetan Buddhists by Padmasambhava.
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 Manas River is a transboundary river in the Himalayan foothills between southern Bhutan and India. It is named after Manasa, the serpent god in Hindu mythology. It is the largest river system of Bhutan, among its four major river systems; the other three are Amo Chu or Torsa river, Wong Chu or Raidak, Puna Tshang Chu or Sankosh. It is met by three other major streams before it again debouches into India in western Assam. The total length of the river is 400 kilometres (250 mi), flows through Tibet, China for 24 km (15 mi), flows in Bhutan for 272 kilometres (169 mi) and then flows through Assam for 104 kilometres (65 mi) before it joins the mighty Brahmaputra River at Jogighopa. Another major tributary of the Manas, the Aie River joins it in Assam at Bangpari.
Royal Manas National Park is Bhutan's oldest national park, and the Royal government considers it the "conservation showpiece of the Kingdom" and a "genetic depository" for valuable plants. It has an area of 1,057 square kilometres (408 sq mi) and covers eastern Sarpang District, the western half of Zhemgang District, and western Pemagatshel District.
Namcha Barwa Himal, also known as Namjagbarwa syntaxis or Namjagbarwa Group Complex, is the easternmost section of the Himalaya in southeastern Tibet and northeastern India. This section spans 180 km from the headwaters of the Siyom River on the international border NE into Tibet to the canyon of the Yarlung Tsangpo, where the Himalaya are said to end, although high ranges actually continue another 300 km east.
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 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 Himalayan states are a group of countries straddling the Himalayan mountain range in Asia. The area is divided between the Western Himalaya and the Eastern Himalaya. Two sovereign states, Nepal and Bhutan, are located almost entirely within the mountain range. The range also covers southern Tibet, the Himalayan region of North and Northeast India, Sikkim, northern Pakistan, and eastern Afghanistan. Northern Myanmar is sometimes also included.
