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 Tibet; 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 .
18-691: The mountains of Bhutan define its three main geographic zones: the Great Himalaya , the Lower Himalayan Range (or Inner Himalaya), and the Sub-Himalayan Range . The snowcapped Great Himalaya in the north ranges from about 5,500 metres (18,000 ft) to peaks of over 7,500 metres (24,600 ft) above sea level, extending along the Bhutan-Tibet border. The northern region consists of an arc of glaciated mountain peaks with an arctic climate at
36-598: A major peak stands over Thrumshing La. To the east runs another lesser spur of mountains separating Lhuentse and Trashiyangse Valleys . To the east of the Manas River system, the Tawang Range (also called Kollong) forms the eastern boundary of Bhutan. The Tawang Range originates in Tibet , to the northeast of Arunachal Pradesh . Great Himalaya The Great Himalayas (also known as Greater Himalayas or Himadri )

Lunana Gewog Lunana Gewog is a gewog (village block) of Gasa District , Bhutan . The village Lunana is the administrative center of Lunana Gewog. The gewog lies almost entirely within protected areas, mostly in Jigme Dorji National Park , though eastern sections are part of Wangchuck Centennial Park . Lunana contains many of Bhutan's glaciers . In addition to
72-661: Is divided by another southward spur, the Donga Range, whose valleys tend to be steeper ravines. Unlike the Great Himalaya, there are no glaciers in the Inner Himalayan ranges, though some summits and upper slopes are covered with moraines . The Black Mountains , lie to the east of the Sankosh River . Midway between Punakha and Trongsa , they separate western Bhutan from the ethnolinguistically diverse central regions and
90-534: Is one of the four parallel sub-ranges of the Himalayas . It is the highest in altitude and extends for about 2,300 km (1,400 mi) from northern Pakistan to the Indian state of Arunachal Pradesh , passing through China , Nepal , and Bhutan . The sub-range has an average elevation of 6,100 m (20,000 ft) and contains many of the world’s tallest peaks including the eight-thousanders and Mount Everest ,
108-559: The Black Mountains in central Bhutan, which form a watershed between two major river systems, the punatsangchhu ( Sankosh River ) and the Drangme Chhu . Central valleys are separated from the east by the Donga Range. The more isolated mountain valleys protect several tiny, distinct cultural and linguistic groups . Bhutan controls several strategic Himalayan mountain passes including routes between Tibet and Assam . These routes, being
126-620: The Lakha , Nyenkha , and 'Olekha languages, representing distantly related Tibetan and East Bodish language groups. Between Trongsa and Jakar runs another mountain range, crossed by Yuto La pass (also called Yotong La). Continuing east, there is another ridge between Jakar and the Kuri Chhu valley, crossed by Ura La pass in Ura Gewog at 3,600 metres (11,800 ft). The steep Donga Range separates Bumthang and Lhuentse Districts and forms
144-785: The Great Himalaya, such as Mount Jitchu Drake , lie squarely within Gasa. The Great Himalaya contains most of the glaciers of Bhutan . This region contains the vast majority of Bhutan's 677 glaciers and 2,674 glacial lakes and subsidiary lakes, out of which 25 pose a risk of GLOFs . The vast number of glaciers in Bhutan are classed as "valley" and "mountain glaciers," although significant numbers of "ice apron," and "niche glacier" types also exist. Some glacial lakes, such as Thorthormi Lake in Lunana Gewog , are not single bodies of water but collections supraglacial ponds. The Lower Himalayan Ranges , also called
162-562: The Himalaya by its rivers , fed by glacial melt and monsoon rains. Much of the Bhutanese population is concentrated in valleys and lowlands, separated by the rugged southward spurs of the Inner Himalaya. Despite modernization and development of transport in Bhutan , including a national highway system, travel from one valley to the next remains difficult. Western valleys are bound to the east by
180-772: The Inner Himalaya, are southward spurs of the Great Himalaya , dominating the midsection of Bhutan. The Dongkya Range forms the trijunction of the Bhutan - Sikkim - Tibet border, separating Sikkim from the Chumbi Valley The Black Mountains in central Bhutan form a watershed between two major river systems, the Mo Chhu and the Drangme Chhu. Peaks in the Black Mountains range between 1,500 metres (4,900 ft) and 2,700 metres (8,900 ft) above sea level. Eastern Bhutan
198-515: The bulk of Gasa District ; northernmost Wangdue Phodrang District ; and northern Bumthang and Lhuentse Districts . The highest point in Bhutan is Gangkhar Puensum , which has the distinction of being the highest unclimbed mountain in the world, at 7,570 metres (24,840 ft). Some massive summits such as Gangkhar Puensum, Kula Kangri , and Tongshanjiabu lie in territory disputed among Bhutan and China . According to Bhutanese claims, these giants should be part of Gasa District . Other peaks of

Pele La pass at 3,350 metres (10,990 ft) is historically and modernly the most important pass in the Black Mountains. The isolation of populations in the Black Mountain area has produced great linguistic and ethnic diversity: it is the home of
234-477: The economic and cultural heart of the kingdom, including most of its dzongs . These mountainous areas are contrasted with the hilly Sub-Himalaya, with elevations of up to 1,500 metres (4,900 ft), and the lower Duars . Many lower mountain ranges are composed of coarse granite sandstone, while rocks at the highest elevations consist of gneiss among upheaved strata of mica and talcose slate. Many ranges are abundant in limestone. Bhutan's valleys are carved into
252-500: The highest elevations. Watered by snow-fed rivers, alpine valleys in this region provide pasturage for livestock tended by a sparse population of migratory shepherds. Spur-like mountain ranges of the Lower Himalaya, between 1,500 metres (4,900 ft) and 5,500 metres (18,000 ft), run northwest to southeast in western Bhutan, and northeast to southwest in eastern Bhutan. These mountains, and especially their western valleys, make up

The closure of the Tibetan border following the Chinese invasion of Tibet brought changes to neighboring areas, as refugees from Tibet arrived with their yaks , which they sold off at low prices. However, because there were no direct routes into Lunana from Tibet, yaks were brought into Lunana from Laya and Sephu in Wangdue Phodrang District . Taxes on horses and yaks, which had been
306-669: The only way into the kingdom, along with centuries-old policies of isolationism , have gained Bhutan the nickname "Mountain Fortress of the Gods." Although the British established a protectorate over Bhutan and occupied its lowlands, the mountainous interior has never been successfully invaded. The mountains of Great Himalaya dominate the north of Bhutan, where peaks can easily reach 7,000 metres (23,000 ft). The tallest peaks range, from west to east, along northern Haa , Paro and Thimphu Districts ;
324-572: The watershed between the Raidāk and Manas River systems. Northeastern portions of the Donga are known as Kurtoe (modern Kurtoe Gewog , historical Kurtoed Province ). Thrumshing La pass, also called Donga Pass, provides the only road access across the Donga Range at 3,787 metres (12,425 ft). The steep Rodang La further north provides non-motor communication, and several southerly passes including Thebong La are used by herders. At 20,965 feet (6,390 m),
