157-870: A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains , the Alps , the Himalayas or the Andes . Usually, a river or stream carves out such splits between mountains. Examples of mountain-type canyons are Provo Canyon in Utah or Yosemite Valley in California's Sierra Nevada . Canyons within mountains, or gorges that have an opening on only one side, are called box canyons. Slot canyons are very narrow canyons that often have smooth walls. Steep-sided valleys in

314-585: A European was in the journal of Jacques Legardeur de Saint-Pierre in 1752, where they were called " montagnes de Roche ". Another name given to the place by the Cree is ᐊᓭᓂᐓᒉ Aseniwuche . The Rocky Mountains are the easternmost portion of the expansive North American Cordillera . They are often defined as stretching from the Liard River in British Columbia south to the headwaters of

471-516: A location is dependent on the season, orientation and bearing with respect to the Sun , and the mass of the mountain. As the Sun is the major contributor to the temperature, it is often directly proportional to the received radiation from the Sun with faces receiving more sunlight having a higher heat buildup. In narrow valleys between steep mountain faces, the weather conditions may differ significantly on both

628-523: A mixture of white pine, fir, and spruce that appear as shrub-like krummholz . Finally, rivers and canyons can create a unique forest zone in more arid parts of the mountain range. The Rocky Mountains are an important habitat for a great deal of well-known wildlife, such as wolves , elk , moose , mule and white-tailed deer , pronghorn , mountain goats , bighorn sheep , badgers , black bears , grizzly bears , coyotes , lynxes , cougars , and wolverines . North America's largest herds of elk are in

785-495: A notable increase in the rate of glacier retreat across the region as a result of climate change. The rate of retreat varies across regions depending on the local conditions. Since 1975, a marked increase in the loss of glacial mass from 5–13 Gt/yr to 16–24 Gt/yr has been observed with an estimated 13% overall decrease in glacial coverage in the Himalayas. The resulting climate variations and changes in hydrology could affect

942-893: A similar relationship to tourism promotions by the Great Northern Railway . While settlers filled the valleys and mining towns, conservation and preservation ethics began to take hold. U.S. President Benjamin Harrison established several forest reserves in the Rocky Mountains in 1891–1892. In 1905, U.S. President Theodore Roosevelt extended the Medicine Bow Forest Reserve to include the area now managed as Rocky Mountain National Park . Economic development began to center on mining, forestry , agriculture, and recreation , as well as on

1099-824: Is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau . The range has several peaks exceeding an elevation of 8,000 m (26,000 ft) including Mount Everest , the highest mountain on Earth. The mountain range runs for 2,400 km (1,500 mi) as an arc from west-northwest to east-southeast at the northern end of the Indian subcontinent. The Himalayas occupy an area of 595,000 km (230,000 sq mi) across six countries – Afghanistan , Bhutan , China , India , Nepal , and Pakistan . The sovereignty of

1256-577: Is actually 1 km wider than the Grand Canyon, making it the widest canyon in the world. Some canyons have notable cultural significance. Evidence of archaic humans has been discovered in Africa's Olduvai Gorge . In the southwestern United States, canyons are important archeologically because of the many cliff-dwellings built in such areas, largely by the ancient Pueblo people who were their first inhabitants. The following list contains only

1413-716: Is also the source of major streams of the Ganges river system. The Eastern Himalayas form the eastern most stretch of the range and consist of the states of parts of Tibet in China, Sikkim , Assam , Arunachal Pradesh , parts of other North East Indian states and north West Bengal in India, entirety of Bhutan, mountain regions of central and eastern Nepal, and most of the western lowlands in Nepal. The eastern Himalayas broadly consists of two regions–the western Nepal Himalayas and

1570-518: Is among the highest in the world, at typically around 5,500 m (18,000 ft) while several equatorial mountains such as in New Guinea , the Rwenzoris , and Colombia , have a snow line at 900 m (3,000 ft) lower. As the physical features of mountains are irregular, with broken jagged contours, there can be wide variations in temperature over short distances. The temperature at

1727-479: Is amongst the most affected regions due to climate change . Since the late 20th century, scientists have reported a notable increase in the rate of glacier retreat and changes occurring at a far rapid rate. As per a 2019 assessment, the Himalayan region, which had experienced a temperature rise of 0.1 °C (32.2 °F) per decade was warming at an increased rate of 0.1 °C (32.2 °F) per decade over

1884-492: Is followed by monsoon rains from June to September. The post monsoon season is largely devoid of rain and snow before beginning of cold winters in December-January with intermediate spring before the summer. There are localised wind pressure systems at high altitudes resulting in heavy winds. Due to its high altitude, the range blocks the flow of cold winds from the north into the Indian subcontinent. This causes

2041-603: Is found in the mixed deciduous and conifer forests of the Eastern Himalayas and the Himalayan water shrew are found on the river banks. The forests of the foothills are inhabited by several different primates, including the endangered Gee's golden langur and the Kashmir gray langur , within highly restricted ranges in the east and west of the Himalayas, respectively. The yaks are large domesticated cattle found in

2198-560: Is home to more than a billion people. In 2011, the population in the Himalayan region was estimated to be about 52.8 million with the combined drainage basin of the Himalayan rivers home to nearly 600 million. Of this, 7.96 million (15.1% of the total Himalayan population) live in Eastern Himalayas, 19.22 million in Central Himalayas (36.4%), and 25.59 million reside in Western Himalayas (48.5%). The population of

2355-794: Is in the Rocky Mountains and designates the line at which waters flow either to the Atlantic or Pacific Oceans. Triple Divide Peak (2,440 m or 8,020 ft) in Glacier National Park is so named because water falling on the mountain reaches not only the Atlantic and Pacific but Hudson Bay as well. Farther north in Alberta, the Athabasca and other rivers feed the basin of the Mackenzie River , which has its outlet on

2512-706: Is natural gas that arises from coal, either through bacterial action or through exposure to high temperature. Coalbed methane supplies 7 percent of the natural gas used in the U.S. The largest coalbed methane sources in the Rocky Mountains are in the San Juan Basin in New Mexico and Colorado and the Powder River Basin in Wyoming. These two basins are estimated to contain 38 trillion cubic feet of gas. Coalbed methane can be recovered by dewatering

2669-675: Is occasionally used in the United Kingdom . In South Africa, kloof (in Krantzkloof Nature Reserve ) is used along with canyon (as in Blyde River Canyon ) and gorge (in Oribi Gorge ). Most canyons were formed by a process of long-time erosion from a plateau or table-land level. The cliffs form because harder rock strata that are resistant to erosion and weathering remain exposed on

2826-614: Is one of the youngest mountain ranges on the planet and consists of uplifted sedimentary and metamorphic rock . According to the modern theory of plate tectonics , it was formed as a result of a continental collision and orogeny along the convergent boundary between the India and Eurasian Plates . During the Jurassic period (201 to 145 mya ), the Tethys Ocean formed the southern border of then existent Eurasian landmass. When

2983-599: Is similarly imprecise, especially if one includes mountain canyons, as well as canyons cut through relatively flat plateaus (which have a somewhat well-defined rim elevation). The Yarlung Tsangpo Grand Canyon (or Tsangpo Canyon), along the Yarlung Tsangpo River in Tibet , is regarded by some as the deepest canyon on Earth at 5,500 metres (18,000 ft). It is slightly longer than the Grand Canyon in

3140-598: Is soluble to a certain extent, cave systems form in the rock. When a cave system collapses, a canyon is left, as in the Mendip Hills in Somerset and Yorkshire Dales in Yorkshire , England. A box canyon is a small canyon that is generally shorter and narrower than a river canyon, with steep walls on three sides, allowing access and egress only through the mouth of the canyon. Box canyons were frequently used in

3297-642: Is the Fish River Canyon in Namibia . In August 2013, the discovery of Greenland 's Grand Canyon was reported, based on the analysis of data from Operation IceBridge . It is located under an ice sheet. At 750 kilometres (470 mi) long, it is believed to be the longest canyon in the world. Despite not being quite as deep or long as the Grand Canyon, the Capertee Valley in Australia

Resolution of the territorial and treaty issues, the Oregon dispute , was deferred until a later time. In 1819, Spain ceded their rights north of the 42nd Parallel to

3768-479: The Alberta–British Columbia foothills forests . The status of most species in the Rocky Mountains is unknown, due to incomplete information. European-American settlement of the mountains has adversely impacted native species. Examples of some species that have declined include western toads , greenback cutthroat trout , white sturgeon , white-tailed ptarmigan , trumpeter swan , and bighorn sheep. In

3925-755: The Andaman Sea . The Salween , Mekong , Yangtze , and Yellow Rivers all originate from parts of the Tibetan Plateau, north of the great water divide. These are considered distinct from the Himalayan watershed and are known as circum-Himalayan rivers. The Himalayan region has multiple lakes across various elevations including endorheic freshwater and saline lakes . The geology of the lakes vary across geographies depending on various factors such as altitude, climate, water source, and lithology . Tarns are high altitude mountain lakes situated above 5,500 m (18,000 ft) and are formed primarily by

4082-547: The Apache , Arapaho , Bannock , Blackfoot , Cheyenne , Coeur d'Alene , Kalispel , Crow Nation , Flathead , Shoshone , Sioux , Ute , Kutenai (Ktunaxa in Canada), Sekani , Dunne-za , and others. Paleo-Indians hunted the now-extinct mammoth and ancient bison (an animal 20% larger than modern bison) in the foothills and valleys of the mountains. Like the modern tribes that followed them, Paleo-Indians probably migrated to

4239-567: The Bay of Bengal were also formed as a result of the same tectonic processes that formed the Himalayas. The Indian plate continues to be driven horizontally at the Tibetan Plateau at about 67 mm (2.6 in) per year, forcing it to continue to move upwards. About 20 mm (0.79 in) per year is absorbed by thrusting along the Himalaya southern front , which leads to the Himalayas rising by about 5 mm (0.20 in) per year. This makes

4396-759: The Beaufort Sea of the Arctic Ocean. Human population is not very dense in the Rockies, with an average of four people per square kilometer and few cities with over 50,000 people. However, the human population grew rapidly in the Rocky Mountain states between 1950 and 1990. The forty-year statewide increases in population range from 35% in Montana to about 150% in Utah and Colorado. The populations of several mountain towns and communities have doubled in

4553-709: The Bull Lake Glaciation , which began about 150,000 years ago, and the Pinedale Glaciation , which perhaps remained at full glaciation until 15,000–20,000 years ago. All of these geological processes exposed a complex set of rocks at the surface. For example, volcanic rock from the Paleogene and Neogene periods (66 million – 2.6 million years ago) occurs in the San Juan Mountains and in other areas. Millennia of severe erosion in

4710-608: The Canadian Pacific Railway eventually followed the Kicking Horse and Rogers Passes to the Pacific Ocean. Canadian railway officials also convinced Parliament to set aside vast areas of the Canadian Rockies as Jasper , Banff , Yoho , and Waterton Lakes National Parks , laying the foundation for a tourism industry which thrives to this day. Glacier National Park (MT) was established with

The mountains are spread across more than eight degrees of latitude and hence includes a wide range of climatic zones including sub-tropical , temperate , and semi-arid . The climate in a region is determined by factors such as altitude, latitude, and the impact on monsoon. There are generally five seasons: summer, monsoon, autumn or post-monsoon, winter, and spring. The summer in April-May

6123-483: The Kashmir valley . The higher elevations consist of rock fragements and lithosols with very low humus content. The Himalayas and the Central Asian mountain ranges consist of the third-largest deposit of ice and snow in the world, after the Antarctic and Arctic regions. It is often referred to as the "Third Pole" as it encompasses about 15,000 glaciers, which store about 12,000 km (2,900 cu mi) of fresh water. The South Col and Khumbu Glacier in

6280-399: The Kumaon region. The northern extremes of the Great Himalayas in Kashmir and Ladakh receive only 3–6 in (76–152 mm) of rainfall per year. During the winter season, a high pressure system develops over Central Asia, which results in winds flowing towards the Himalayas. However, due to the presence of less water bodies in the Central Asian region, the moisture content is low. As

The actions are aimed at reducing emissions , increase the usage of renewable energy , and sustainable environmental practices. As the local population increasingly experience the impact of the changes in climate such as variations in temperature and precipitation, and change in vegetation, they are forced to adapt for

7379-405: The Pecos River , a tributary of the Rio Grande , in New Mexico. The Rockies vary in width from 110 to 480 kilometres (70 to 300 miles). The Rocky Mountains contain the highest peaks in central North America. The range's highest peak is Mount Elbert in Colorado at 4,401 metres (14,440 feet) above sea level. Mount Robson in British Columbia, at 3,954 m (12,972 ft), is the highest peak in

7536-510: The Sawtooths in central Idaho. The Great Basin and Columbia River Plateau separate these subranges from distinct ranges further to the west. In Canada, the western edge of the Rockies is formed by the huge Rocky Mountain Trench , which runs the length of British Columbia from its beginning as the Kechika Valley on the south bank of the Liard River , to the middle Lake Koocanusa valley in northwestern Montana. The Canadian Rockies are defined by Canadian geographers as everything south of

Fossils of species such as giraffe , and hippopotamus have been found in the foothills, suggesting the presence of African species some time ago. Large mammals such as Indian elephant , and Indian rhinoceros are confined to the densely forested moist ecosystems in the Eastern and Central Himalayas. Many of

8321-430: The Wyoming Basin transformed intermountain basins into a relatively flat terrain. The Tetons and other north-central ranges contain folded and faulted rocks of Paleozoic and Mesozoic age draped above cores of Proterozoic and Archean igneous and metamorphic rocks ranging in age from 1.2 billion (e.g., Tetons) to more than 3.3 billion years ( Beartooth Mountains ). There are a wide range of environmental factors in

8478-401: The Yarlung Tsangpo River . The Himalayas consists of four parallel mountain ranges: the Sivalik Hills on the south; the Lower Himalayas ; the Great Himalayas , which is the highest and central range; and the Tibetan Himalayas on the north. The range varies in width from 350 km (220 mi) in the north-west to 150 km (93 mi) in the south-east. The Himalayan range is one of

The glaciers joined with the ice stream network in the Karakoram in the west, the Tibetan inland ice in the north, and came to an end below an elevation of 1,000–2,000 m (3,300–6,600 ft) in the south. While the current valley glaciers of the Himalaya reach at most 20–32 km (12–20 mi) in length, several of

8949-527: The seabed of the continental slope are referred to as submarine canyons . Unlike canyons on land, submarine canyons are thought to be formed by turbidity currents and landslides . The word canyon is Spanish in origin ( cañón , pronounced [kaˈɲon] ), with the same meaning. The word canyon is generally used in North America , while the words gorge and ravine (French in origin) are used in Europe and Oceania , though gorge and ravine are also used in some parts of North America. In

While these lakes support a range of ecosystems and local communities, many of them remain poorly studied in terms of their hydrology and biodiversity. Due to its location and size, the Himalayas acts as a climatic barrier which affects the weather conditions of

10205-413: The Himalayan region geologically active and the movement of the Indian plate into the Asian plate makes the region seismically active, leading to earthquakes from time to time. The northern slopes of the Himalayas have a thicker soil cover than the southern slopes due to presence of lesser number of rivers and streams. These soils are loamy and are dark brown in colour, and are covered with forests in

10362-531: The Himalayan region including Bhutan, Nepal, Bangladesh, India, and Pakistan are amongst the most vulnerable countries in the Global South due to climate change. The temperature rise increases the incidence of tropical diseases such as malaria , and dengue further north. The extreme weather events might cause physical harm directly and indirectly due to lack of access and contamination of drinking water , pollution , exposure to chemicals, and destruction of crops, and drought . The climate change also impact

Native American populations were extirpated from most of their historical ranges by disease, warfare, habitat loss (eradication of the bison), and continued assaults on their culture. In 1739, French fur traders Pierre and Paul Mallet, while journeying through the Great Plains, discovered a range of mountains at the headwaters of the Platte River , which local American Indian tribes called

11618-596: The Northern Rockies surrounding Tumbler Ridge, British Columbia . Abandoned mines with their wakes of mine tailings and toxic wastes dot the Rocky Mountain landscape. In one major example, eighty years of zinc mining profoundly polluted the river and bank near Eagle River in north-central Colorado. High concentrations of the metal carried by spring runoff harmed algae , moss , and trout populations. An economic analysis of mining effects at this site revealed declining property values, degraded water quality, and

11775-543: The Pacific Ocean. The Lewis and Clark Expedition (1804–1806) was the first scientific reconnaissance of the Rocky Mountains. Specimens were collected for contemporary botanists, zoologists, and geologists. The expedition was said to have paved the way to (and through) the Rocky Mountains for European-Americans from the East, although Lewis and Clark met at least 11 European-American mountain men during their travels. Mountain men , primarily French, Spanish, and British, roamed

11932-611: The Plains and the Alpine tundra . The Great Plains lie to the east of the Rockies and is characterized by prairie grasses (below roughly 550 m or 1,800 ft). Alpine tundra occurs in regions above the tree-line for the Rocky Mountains, which varies from 3,700 m (12,000 ft) in New Mexico to 760 m (2,500 ft) at the northern end of the Rockies (near the Yukon). The U.S. Geological Survey defines ten forested zones in

12089-959: The Rockies include the La Sal Range along the Utah -Colorado border, the Abajo Mountains and Henry Mountains of Southeastern Utah, the Uinta Range of Utah and Wyoming, and the Teton Range of Wyoming and Idaho. The western edge of the Rockies includes ranges such as the Wasatch near Salt Lake City , the San Juan Mountains of New Mexico and Colorado, the Bitterroots along the Idaho-Montana border, and

12246-464: The Rockies. Zones in more southern, warmer, or drier areas are defined by the presence of pinyon pines / junipers , ponderosa pines , or oaks mixed with pines . In more northern, colder, or wetter areas, zones are defined by Douglas firs , Cascadian species (such as western hemlock ), lodgepole pines / quaking aspens , or firs mixed with spruce . Near tree-line, zones can consist of white pines (such as whitebark pine or bristlecone pine ); or

12403-590: The Rocky Mountains from 1720 to 1800 seeking mineral deposits and furs. The fur-trading North West Company established Rocky Mountain House as a trading post in what is now the Rocky Mountain Foothills of present-day Alberta in 1799, and their business rivals the Hudson's Bay Company established Acton House nearby. These posts served as bases for most European activity in the Canadian Rockies in

12560-603: The Rocky Mountains is one of more rapid change. The Spanish explorer Francisco Vázquez de Coronado —with a group of soldiers and missionaries marched into the Rocky Mountain region from the south in 1540. In 1610, the Spanish founded the city of Santa Fe , the oldest continuous seat of government in the United States, at the foot of the Rockies in present-day New Mexico. The introduction of the horse, metal tools, rifles, new diseases, and different cultures profoundly changed

12717-622: The Rocky Mountains on the Oregon Trail beginning in the 1840s. The Mormons began settling near the Great Salt Lake in 1847. From 1859 to 1864, gold was discovered in Colorado, Idaho, Montana, and British Columbia, sparking several gold rushes bringing thousands of prospectors and miners to explore every mountain and canyon and to create the Rocky Mountains' first major industry. The Idaho gold rush alone produced more gold than

12874-622: The Rocky Mountains. The Rockies range in latitude between the Liard River in British Columbia (at 59° N) and the Rio Grande in New Mexico (at 35° N). Prairie occurs at or below 550 metres (1,800 ft), while the highest peak in the range is Mount Elbert at 4,400 metres (14,440 ft). Precipitation ranges from 250 millimetres (10 in) per year in the southern valleys to 1,500 millimetres (60 in) per year locally in

13031-671: The Sutlej River in the east to the Kali River in the west. The region comprises parts of Sivalik and Great Himalayas. At lower elevations below 2,400 m (7,900 ft), the region has a temperate climate and consists of permanent settlements. At elevations higher than 4,300 m (14,100 ft), permanent snow caps cover the Great Himalayas with the highest peaks being Nanda Devi at 7,817 m (25,646 ft) and Kamet at 7,756 m (25,446 ft). The region

13188-530: The Tethys ocean. The upliftment of the Himalayas occurred gradually and as the Great Himalayas became higher, they became a climatic barrier and blocked the winds, which resulted in lesser precipitation on the upper slopes. The lower slopes continued to be eroded by the rivers, which flowed in the gaps between the mountains and the folded lower Shivalik Hills and the Lesser Himalayas were formed due to

13345-668: The Tibetan Himalayas and the plateau beyond. It also played a role in the formation of Central Asian deserts such as the Taklamakan and Gobi . The monsoon is triggered by the different rates of heating and cooling between the Indian Ocean and Central Asia, which create large differences in the atmospheric pressure prevailing above each. As the Central Asian landmass heats up during the summer compared to

13502-404: The U.S. portion of the mountain range, apex predators such as grizzly bears and wolf packs had been extirpated from their original ranges, but have partially recovered due to conservation measures and reintroduction . Other recovering species include the bald eagle and the peregrine falcon . Since the last great ice age, the Rocky Mountains were home first to indigenous peoples including

13659-743: The United Kingdom and the United States over the next few decades failed to settle upon a compromise boundary and the Oregon Dispute became important in geopolitical diplomacy between the British Empire and the new American Republic. In 1841, James Sinclair , Chief Factor of the Hudson's Bay Company, guided some 200 settlers from the Red River Colony west to bolster settlement around Fort Vancouver in an attempt to retain

13816-560: The United States, though these rights did not include possession and also included obligations to Britain and Russia concerning their claims in the same region. After 1802, fur traders and explorers ushered in the first widespread American presence in the Rockies south of the 49th parallel. The more famous of these include William Henry Ashley , Jim Bridger , Kit Carson , John Colter , Thomas Fitzpatrick , Andrew Henry , and Jedediah Smith . On July 24, 1832, Benjamin Bonneville led

13973-531: The United States, with an average depth of 1,600 metres (5,200 ft) and a volume of 4.17 trillion cubic metres (147 trillion cubic feet), is one of the world's largest canyons. It was among the 28 finalists of the New 7 Wonders of Nature worldwide poll. (Some referred to it as one of the seven natural wonders of the world .) The largest canyon in Europe is Tara River Canyon . The largest canyon in Africa

14130-625: The United States. Others consider the Kali Gandaki Gorge in midwest Nepal to be the deepest canyon, with a 6,400-metre (21,000 ft) difference between the level of the river and the peaks surrounding it. Vying for the deepest canyon in the Americas is the Cotahuasi Canyon and Colca Canyon , in southern Peru. Both have been measured at over 3,500 metres (11,500 ft) deep. The Grand Canyon of northern Arizona in

14287-534: The Western Himalayas. The high altitude mountainous areas are mostly barren or, at the most, sparsely sprinkled with stunted bushes. The Himalayas are home to various medicinal plants such as Abies pindrow used to treat bronchitis , Andrachne cordifolia used for snake bites , and Callicarpa arborea used for skin diseases . Nearly a fifth of the plant species in the Himalayas are used for medicinal purposes. Climate change , illegal deforestation , and introduction of non native species have had an effect on

14444-455: The animal species found in the region are unique and endemic or nearly endemic to the region. Other large animal species found in the Himalayas include Asiatic black bear , clouded leopard , and herbivores such as bharal , Himalayan tahr , takin , Himalayan serow , Himalayan musk deer , and Himalayan goral . Animals found at higher altitudes include brown bear , and the elusive snow leopard , which mainly feed on bharal. The red panda

14601-720: The bend of the Indus River along the Pakistan-Afghanistan border region in the north-west to the Satlej river basin in India in the south-east. Most of the region lies in the Kashmir territory disputed between India and Pakistan with certain portions of the Indian state of Himachal Pradesh . The Indus forms the division between the Western Himalayas and the Karakoram range to the north. The Western Himalayas include

14758-745: The canyon walls, in a process known as frost wedging. Canyon walls are often formed of resistant sandstones or granite . Sometimes large rivers run through canyons as the result of gradual geological uplift. These are called entrenched rivers , because they are unable to easily alter their course. In the United States, the Colorado River in the Southwest and the Snake River in the Northwest are two examples of tectonic uplift . Canyons often form in areas of limestone rock. As limestone

14915-428: The coal bed, and separating the gas from the water; or injecting water to fracture the coal to release the gas (so-called hydraulic fracturing ). Agriculture and forestry are major industries. Agriculture includes dryland and irrigated farming and livestock grazing. Livestock are frequently moved between high-elevation summer pastures and low-elevation winter pastures, a practice known as transhumance . Every year

15072-510: The cold winds from Central Asia , and plays a significant roles in influencing the monsoons . The vast size, varying altitude range, and complex topography of the Himalayas result in a wide range of climates, from humid and subtropical to cold and dry desert conditions. The mountains have profoundly shaped the cultures of South Asia and Tibet . Many Himalayan peaks are considered sacred across various Indian and Tibetan religions such as Hinduism , Buddhism , Jainism , and Bon . Hence,

15229-453: The condensation occurs at higher altitudes in the north, there is more precipitation in the Great Himalayas in the west during the winter rains and the precipitation reduces towards the east. In January, the Kumaon region receives about 3 in (76 mm) of rainfall compared to about 1 in (25 mm) in the Eastern Himalayas. The Himalayan region has a highly sensitive ecosystem and

15386-475: The downwarping of the intermediate lands. Minor streams ran between the faults within the mountains until they joined the major river systems in the plains. Intermediate valleys such as Kashmir and Kathmandu were formed from temporary lakes that were formed during pleistocene , which dried up later. The Himalayan region is made up of five geological zones– the Sub-Himalayan Zone bound by

15543-722: The early 19th century. Among the most notable are the expeditions of David Thompson , who followed the Columbia River to the Pacific Ocean. On his 1811 expedition, he camped at the junction of the Columbia River and the Snake River and erected a pole and notice claiming the area for the United Kingdom and stating the intention of the North West Company to build a fort at the site. By the Anglo-American Convention of 1818 , which established

15700-508: The eastern Assam Himalayas. The Nepal Himalayas forms the centre of the Himalayan curve and extend for 800 km (500 mi) between the Kali and Teesta Rivers . The Great Himalayas in the region form the highest part of the entire Himalayas and consist of many of the eight-thousanders including Everest, Kanchenjunga at 8,586 m (28,169 ft), and Makalu at 8,463 m (27,766 ft). These mountains host large glaciers that form

15857-495: The ecosystem. At higher altitudes, Eastern and Western Himalayan subalpine conifer forests consisting of various conifers occur. Chir pine is the dominant species which occurs at elevations from 800–900 m (2,600–3,000 ft). Other species include Deodar cedar , which grows at altitudes of 1,900–2,700 m (6,200–8,900 ft), blue pine and morinda spruce between 2,200–3,000 m (7,200–9,800 ft). At higher altitudes, alpine shrubs and meadows occur above

16014-544: The edge of the North American Plate boundary, far to the west of the Rocky Mountain region. It was not until 80 Ma that these effects began reaching the Rockies. The current Rocky Mountains arose in the Laramide orogeny from between 80 and 55 Ma. For the Canadian Rockies, the mountain building is analogous to pushing a rug on a hardwood floor: the rug bunches up and forms wrinkles (mountains). In Canada,

16171-510: The first wagon train across the Rocky Mountains by using South Pass in the present State of Wyoming. Similarly, in the wake of Mackenzie's 1793 expedition, fur trading posts were established west of the Northern Rockies in a region of the northern Interior Plateau of British Columbia which came to be known as New Caledonia , beginning with Fort McLeod (today's community of McLeod Lake) and Fort Fraser , but ultimately focused on Stuart Lake Post (today's Fort St. James ). Negotiations between

16328-417: The flora and fauna of the region. Changes might decrease the territory available for local wildlife and reduction in prey for the predators . This puts the animals in conflict with humans as humans might encroach animal territories and the animals might venture into human habitats for search of food, which might exacerbate the economic loss of the local population. The Himalayan nations are signatories of

16485-521: The flora of the range. The increase in temperature has resulted in shifting of various species to higher elevations, and early flowering and fruiting. Many of the animal species are from the tropics, which have adapted to the various conditions across the Himalayan range. Some of the species of the Eastern Himalayas are similar to those found in East and South East Asia , while the animals of

16642-459: The formation of the Tibetan plateau . During miocene (20 mya), the increasing collision between the plates resulted in the top layer of metamorphic rocks getting peeled, which moved southwards to form nappes with trenches in between. As the mountains received rainfall, the waters flowing down the mountains eroded and steepened the southern slopes. The silt deposited by these rivers and streams in

16799-481: The forty years 1972–2012. Jackson, Wyoming , increased 260%, from 1,244 to 4,472 residents, in those forty years. The rocks in the Rocky Mountains were formed before the mountains were raised by tectonic forces. The oldest rock is Precambrian metamorphic rock that forms the core of the North American continent. There is also Precambrian sedimentary argillite , dating back to 1.7 billion years ago. During

16956-456: The last ice age , and give rise to some of the world's major rivers such as the Indus , Ganges , and Tsangpo – Brahmaputra . Their combined drainage basin is home to nearly 600 million people including 52.8 million living in the vicinity of the Himalayas. The region is also home to many endorheic lakes. The Himalayas have a major impact on the climate of the Indian subcontinent. It blocks

17113-599: The last sixty million years, erosion stripped away the high rocks, revealing the ancestral rocks beneath, and forming the current landscape of the Rockies. Periods of glaciation occurred from the Pleistocene Epoch (1.8 million – 70,000 years ago) to the Holocene Epoch (fewer than 11,000 years ago). These ice ages left their mark on the Rockies, forming extensive glacial landforms, such as U-shaped valleys and cirques . Recent glacial episodes included

17270-520: The limestone laid down in the shallow sea. The mountains eroded throughout the late Paleozoic and early Mesozoic , leaving extensive deposits of sedimentary rock . Terranes began colliding with the western edge of North America in the Mississippian (approximately 350 million years ago), causing the Antler orogeny . For 270 million years, the focus of the effects of plate collisions were near

17427-458: The livelihoods of the people in the Himalayas and the plains below. Despite its greater size, the Himalayas does not form a water divide across its span because of the multiple river systems that cut across the range. While the mountains were formed gradually, the rivers concurrently cut across deeper gorges ranging from 1,500–5,000 m (4,900–16,400 ft) in depth and 10–50 km (6.2–31.1 mi) in width. The actual water divide lies to

17584-535: The loss of recreational opportunities. The analysis also revealed that cleanup of the river could yield $ 2.3 million in additional revenue from recreation. In 1983, the former owner of the zinc mine was sued by the Colorado Attorney General for the $ 4.8 million cleanup costs; five years later, ecological recovery was considerable. The Rocky Mountains contain several sedimentary basins that are rich in coalbed methane . Coalbed methane

17741-590: The lower ranges on the southern slopes speak Indo-European languages. The inhabitants of the Western Himalayas include the Kashmiri people , who speak Kashmiri in the Vale of Kashmir and the Gujjar and Gaddi people , who speak Gujari and Gaddi respectively in the lower altitudes of Jammu and Himachal Pradesh in India. The last two are pastoral and nomadic people, who own flocks of cattle and migrate across

17898-468: The lowlands and grassland meadows in the mid altitudes. The composition and texture of the soils in the Himalayas also vary across regions. In the Eastern Himalayas , the wet soils has a high humus content conducive for growing tea . Podzolic soils occur in the eastern range of the Indus basin between the Indus and Shyok Rivers . The Ladakh region is generally dry with saline soil while fertile alluvial soils occur in select river valleys such as

18055-419: The main valley glaciers were 60–112 km (37–70 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 would have been at least 7.0–8.3 °C (12.6–14.9 °F) colder than it is today. Since the late 20th century, scientists have reported

18212-411: The majority of the languages belonging to the first two categories. The Tibetan Himalayas are inhabited by Tibetan people , who speak Tibeto-Burman languages. The Great Himalayas are mostly inhabited by nomadic groups and tribes, with most of the population in Lesser Himalayas , and Shivalik Hills . People towards the Great Himalayas in the north parts mostly speak Tibeto-Burman, while populations in

18369-404: The margins. The mountains act as heat islands and heavier mountains absorb and retain more heat than the surroundings, and therefore influences the amount of heat needed to raise the temperature from the winter minimum to the summer maximum. However, soil temperatures mostly remain the same on both the sides of a mountain at altitudes higher than 4,500 m (14,800 ft). Temperatures in

18526-626: The most notable canyons of the world, grouped by region. Venus has many craters and canyons on its surface. The troughs on the planet are part of a system of canyons that is more than 6,400 km long. [REDACTED] Environment portal Rocky Mountains The Rocky Mountains , also known as the Rockies , are a major mountain range and the largest mountain system in North America . The Rocky Mountains stretch 3,000 miles (4,800 kilometers) in straight-line distance from

18683-425: The mountain range, and they are popular tourist destinations, especially for hiking, camping, mountaineering, fishing, hunting, mountain biking, snowmobiling, skiing, and snowboarding. The name of the mountains is a calque of an Algonquian name, specifically Plains Cree ᐊᓯᓃᐘᒋᐩ asinîwaciy (originally transcribed as-sin-wati ), literally "rocky mountain / alp". The first mention of their present name by

18840-643: The mountain range. After explorations of the range by Europeans, such as Sir Alexander Mackenzie , and Anglo-Americans, such as the Lewis and Clark Expedition , natural resources such as minerals and fur drove the initial economic exploitation of the mountains, although the range itself never experienced a dense population. Most of the highest summits of the Rocky Mountains are in Colorado , with that state having an average elevation in excess of 2,000 metres (6,600 ft). Public parks and forest lands protect much of

18997-450: The normal 300 to 500 kilometres (200 to 300 mi). Scientists hypothesize that the shallow angle of the subducting plate increased the friction and other interactions with the thick continental mass above it. Tremendous thrusts piled sheets of crust on top of each other, building the broad, high Rocky Mountain range. The current southern Rockies were forced upwards through the layers of Pennsylvanian and Permian sedimentary remnants of

19154-586: The north of the Himalayas with rivers flowing down both the sides of the mountains. Some of the major river systems and their drainage system outdate the formation of the mountains itself. The water divide is formed by the Karakoram and Hindu Kush ranges on the west and the Ladakh Range on the east, separating the Indus system from Central Asia. On the east, Kailas and Nyenchen Tanglha Mountains separate

19311-654: The northern peaks. Average January temperatures can range from −7 °C (20 °F) in Prince George, British Columbia, to 6 °C (43 °F) in Trinidad, Colorado . Therefore, there is no single monolithic ecosystem for the entire Rocky Mountain Range. Instead, ecologists divide the Rockies into a number of biotic zones . Each zone is defined by whether it can support trees and the presence of one or more indicator species . Two zones that do not support trees are

19468-617: The northernmost part of Western Canada , to New Mexico in the Southwestern United States . Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia 's Terminal Range south of the Liard River and east of the Trench , or in the northeastern foothills of the Brooks Range / British Mountains that face the Beaufort Sea coasts between

19625-678: The northwest, which extend into Central Asia . Its western anchor Nanga Parbat lies south of the northernmost bend of the Indus river in Pakistan-administered Kashmir and its eastern anchor Namcha Barwa lies to the west of the great eastern bend of the Yarlung Tsangpo River in Tibet Autonomous Region of China . The Himalayas occupies an area of 595,000 km (230,000 sq mi) across six countries – Afghanistan , Bhutan , China, India , Nepal , and Pakistan . The sovereignty of

19782-436: The number of glacial lakes , some of which may be prone to dangerous floods. The region is expected to encounter continued increase in average annual temperature and 81% of the region's permafrost is projected to be lost by the end of the century. The increased warming and melting of snow is projected to accelerate the regional river flows until 2060 after which it would decline due to reduction in ice caps and glacier mass. As

19939-403: The ocean below, the difference in pressure creates a thermal low . The moist air from the ocean is pushed inwards towards the low pressure system causing the monsoon winds. It results in precipitation along the slopes due to the orographic effect as the air rises along the mountains and condenses. The monsoon begins at the end of May in the eastern fringes of the range and moves upwards towards

20096-477: The past half a century. The average warm days and nights had also increased by 1.2 days and 1.7 nights per decade while the average cold days and nights had declined by 0.5 and 1 respectively. This has also prolonged the length of the growing season by 4.25 days per decade. The climate change might results in erratic rainfall, varying temperatures, and natural disasters like landslides , and floods . The increasing glacier melt had been followed by an increase in

20253-547: The plains in fall and winter for bison and to the mountains in spring and summer for fish, deer, elk, roots, and berries. In Colorado, along with the crest of the Continental Divide, rock walls that Native Americans built for driving game date back 5,400–5,800 years. A growing body of scientific evidence indicates that indigenous people had significant effects on mammal populations by hunting and on vegetation patterns through deliberate burning. Recent human history of

20410-603: The precipitation is projected to increase concurrently, the annual river flows would be largely unaffected for the Eastern Himalayan rivers fed by monsoons, but would reduce the flows in the Western Himalayan rivers. Almost a billion people live on either side of the mountain and are prone to impact of the climate change. This includes the people who live in the mountains, who are more vulnerable due to temperature variations and other biota. Countries in

20567-399: The range in the Kashmir region is disputed among India, Pakistan, and China. It is bordered by the Karakoram and Hindu Kush ranges on the northwest, Tibetan Plateau in the north, and by the Indo-Gangetic Plain in the south. Its western anchor Nanga Parbat lies south of the northernmost bend of the Indus river and its eastern anchor Namcha Barwa lies to the west of the great bend of

20724-462: The range in the Kashmir region is disputed amongst India, Pakistan, and China. The range varies in width from 350 km (220 mi) in the north-west to 150 km (93 mi) in the south-east. The range has several peaks exceeding an elevation of 8,000 m (26,000 ft) including Mount Everest , the highest mountain on Earth at 8,848 m (29,029 ft). The Himalayas consist of four parallel mountain ranges from south to north:

20881-980: The region  tropical and subtropical , temperate , coniferous , and grasslands . Tropical and subtropical broadleaf forests are mostly constricted to the high temperature and humid regions in Eastern and Central Himalayas , and pockets of Kashmir in the west. There are about 4,000 species of Angiosperms with major vegetation include Dipterocarpus , and Ceylon ironwood on porous soils at elevations below 2,400 m (7,900 ft) and oak , and Indian horse chestnut on lithosol between 1,100–1,700 m (3,600–5,600 ft). Himalayan subtropical pine forests with Himalayan screw pine trees occur above 4,000 m (13,000 ft) and Alder , and bamboo are found on terrains with higher gradient. Temperate forest occur at altitudes between 1,400–3,400 m (4,600–11,200 ft) while moving from south-east to north-west towards higher latitude. Eastern and Western Himalayan broadleaf forests consisting of sal trees dominate

21038-777: The region. More than 800 species of birds have been recorded with a large number of species restricted to the Eastern Himalayas. Amongst the bird species found include magpies such as black-rumped magpie and blue magpie , titmice , choughs , whistling thrushes , and redstarts . Raptors include bearded vulture , black-eared kite , and Himalayan griffon . Snow partridge and Cornish chough are found at altitudes above 5,700 m (18,700 ft). The Himalayan lakes also serve as breeding grounds for species such as black-necked crane and bar-headed goose . There are multiple species of reptiles including Japalura lizards, blind snakes , and insects such as butterflies . Several fresh water fish such as Glyptothorax are found in

21195-428: The region. As of 2022 , there are 575 protected areas established by the nations in the Himalayan-Hindu Kush region, which account for 40% of the land area and 8.5% of the global protected area. There are also four biodiversity hotspots , 12 ecoregions , 348 key biodiversity areas, and six UNESCO World Heritage Sites in the region. The Himalayan region with the associated Indo-Gangetic Plain and Tibetan plateau

21352-435: The same. The Himalayan region belongs to the Indomalayan realm . The flora and fauna of the Himalayas vary broadly across regions depending on the climate and geology. The Himalayas are home to multiple biodiversity hotspots, and is home to an estimated 35,000+ species of plants and 200+ species of animals. An average of 35 new species have been found every year since 1998. There are four types of vegetation found in

21509-593: The same. This has led to increased awareness on the impact of climate change, and adaptations such as change in crop cycles , introduction of drought resistant crops, and plantation of new trees. This has also led to the construction of more dams , canals , and other water structures, to prevent flooding and aid in agriculture. New plantations on barren lands to prevent landslides, and construction of fire lines made of litter and mud to prevent forest fires have been undertaken. However, lack of funding, awareness, access to technology, and government policy are barriers for

21666-618: The scenic areas of the Rocky Mountains draw millions of tourists. The main language of the Rocky Mountains is English. But there are also linguistic pockets of Spanish and indigenous languages. People from all over the world visit the sites to hike, camp, or engage in mountain sports . In the summer season, examples of tourist attractions are: In the United States: In Canada, the mountain range contains these national parks : Glacier National Park in Montana and Waterton Lakes National Park in Alberta border each other and are collectively known as Waterton-Glacier International Peace Park . In

21823-494: The service industries that support them. Tents and camps became ranches and farms, forts and train stations became towns, and some towns became cities. Economic resources of the Rocky Mountains are varied and abundant. Minerals found in the Rocky Mountains include significant deposits of copper, gold, lead, molybdenum , silver, tungsten , and zinc . The Wyoming Basin and several smaller areas contain significant reserves of coal, natural gas, oil shale , and petroleum. For example,

21980-413: The slopes and the plains below. The effect of Himalayas on the hydroclimate impacts millions in the plains as the variability in monsoon rainfall is the main factor behind wet and dry years. As the Himalayas force the monsoon winds to give up most of the moisture before ascending up, the winds became dry once its reaches the north of the mountains. This results in the dry and windy cold desert climate in

22137-399: The slopes based on seasons. Various ethnic people such as Ladakhi , Balti , and Dard live on the north of the Great Himalayas along the Indus basin in the Kashmir and Ladakh regions spread across India, Pakistan, and China. The Dard speak Dard , which is part of Indo-European languages, while the Balti and Lakadkhi people speak Balti , and Ladakhi , which are part of Tibeto-Burman. In

22294-417: The snow-melt of the glaciers. The lower altitude lakes are replenished by a combination of rains, underground springs, and streams. Large lakes in the Himalayan basin were formed in the holocene period, when water pooled in the faults and the water supply was subsequently cut off. There are more than 4500 high altitude lakes of which about 12 large lakes contribute to more than 75% of the total lake area in

22451-409: The source of various rivers of the Ganges - Brahmaputra river system. The high altitude regions are uninhabitable with few mountain passes inbetween that serve as crossovers with the human settlements in the lower valleys. The Assam Himalaya forms the eastern most sub-section that extends eastward for 720 km (450 mi) from the Indian state of Sikkim through Bhutan and north-east India past

22608-470: The summits of several peaks in the region such as Gangkhar Puensum , Machapuchare , and Kailash have been off-limits to climbers. The name of the range is derived from the Sanskrit word Himālay ( हिमालय ) meaning 'abode of snow'. It is a combination of the words him ( हिम ) meaning 'frost/cold' and ālay ( आलय ) meaning 'dwelling/house'. The name of the range is mentioned as Himavat ( Sanskrit : हिमवत्) in older literature such as

22765-454: The super-continent Gondwana broke up nearly 180 mya, the Indo-Australian plate slowly drifted northwards towards Eurasia for 130-140 million years. The Indian Plate broke up with the Australian Plate about 100 mya. The Tethys ocean constricted as the Indian plate moved gradually upward. As both the plates were made of continental crusts , which were less denser than oceanic crusts , the increased compressive forces resulted in folding of

22922-457: The terranes and subduction are the foot pushing the rug, the ancestral rocks are the rug, and the Canadian Shield in the middle of the continent is the hardwood floor. Further south, an unusual subduction may have caused the growth of the Rocky Mountains in the United States, where the Farallon Plate dove at a shallow angle below the North American Plate . This low angle moved the focus of melting and mountain building much farther inland than

23079-545: The trees. The Eastern Himalayan alpine shrub and meadows extend between 3,200–4,200 m (10,500–13,800 ft) and the Western Himalayan alpine shrub and meadows occur at altitudes of 3,600–4,500 m (11,800–14,800 ft). Major vegetation include Juniperus , Rhododendron on rocky terrain facing the Sun, various flowering plants at high elevations, and mosses , and lichens in humid, shaded areas. Interspersed Grasslands occur at certain regions, with thorns and semi-desert vegetation at low precipitation areas in

23236-415: The tropical zone to extend farther north in South Asia than anywhere else in the world. The temperatures are more pronounced in the Brahmaputra valley in the eastern section as it lies at a lower latitude and due to the latent heat of the forced air from the Bay of Bengal which condenses before moving past the Namcha Barwa , the eastern anchor of the Himalayas. Due to this, the permanent snow line

23393-491: The trough between the Himalayas and the Deccan plateau formed the Indo-Gangetic Plain . About 0.6 mya in the pleistocene period, the Himalayas rose higher and became the highest mountains on Earth. In the northern Great Himalayas , new gneiss and granite formations emerged on crystalline rocks that gave rise to the higher peaks. The summit of Mount Everest is made of unmetamorphosed marine ordovician limestone with fossil trilobites , crinoids , and ostracods from

23550-433: The underlying rock bed. The thrust faults created between the folds resulted in granite and basalt rocks from the Earth's mantle protruding through the crust . During the paleogene period (about 50 mya), the Indian plate collided with the Eurasian plate after it completely closed the Tethys ocean gap. The Indian plate continued to subduct under the Eurasian plate over the next 30 million years that resulted in

23707-456: The valley walls. Canyons are much more common in arid areas than in wet areas because physical weathering has a more localized effect in arid zones. The wind and water from the river combine to erode and cut away less resistant materials such as shales . The freezing and expansion of water also serves to help form canyons. Water seeps into cracks between the rocks and freezes, pushing the rocks apart and eventually causing large chunks to break off

23864-409: The west in June and July. There is heavy precipitation in the east which reduces progressively towards the west as the air becomes drier. Cherrapunji in Eastern Himalayas is one of the wettest places on Earth with an annual precipitation of 428 in (10,900 mm). The average annual rainfall varies from 120 in (3,000 mm) in the Eastern Himalayas to about 120 in (3,000 mm) in

24021-778: The winter, skiing is the main attraction, with dozens of Rocky Mountain ski areas and resorts . The adjacent Columbia Mountains in British Columbia contain major resorts such as Panorama and Kicking Horse , as well as Mount Revelstoke National Park and Glacier National Park. There are numerous provincial parks in the British Columbia Rockies, the largest and most notable being Mount Assiniboine Provincial Park , Mount Robson Provincial Park , Northern Rocky Mountains Provincial Park , Kwadacha Wilderness Provincial Park , Stone Mountain Provincial Park and Muncho Lake Provincial Park . Himalaya The Himalayas , or Himalaya ( / ˌ h ɪ m ə ˈ l eɪ . ə , h ɪ ˈ m ɑː l ə j ə / HIM -ə- LAY -ə, hih- MAH -lə-yə )

24178-430: The world's tallest peaks, including Everest. It is mainly composed of granite rocks. The Tibetan Himalayas (also known as Tethys ) form the northern most sub-range of the Himalayas in Tibet . Longitudinally, the range is broadly divided into three regions– western , central , and eastern . The Western Himalayas form the westernmost section of the range and extend for about 560 km (350 mi) from

24335-461: The youngest mountain ranges on Earth and is made up of uplifted sedimentary and metamorphic rocks. It was formed more than 10 mya due to the subduction of the Indian tectonic plate with the Eurasian Plate along the convergent boundary . Due to the continuous movement of the Indian plate, the Himalayas keep rising every year, making them geologically and seismically active. The mountains consist of large glaciers , which are remnants of

24492-404: Was mentioned as Himmaleh in western literature such as Emily Dickinson 's poetry and Henry David Thoreau 's essays. The Himalayas run as an arc for 2,400 km (1,500 mi) from west-northwest to east-southeast at the northern end of the Indian subcontinent , separating the Indo-Gangetic Plains from the Tibetan Plateau . It is bordered by the Karakoram and Hindu Kush ranges on

24649-476: Was originally used to denote the 320 km (200 mi) stretch from Haridwar to the Beas River . The range is about 16 km (9.9 mi) wide on average and the elevation ranges from 900–1,200 m (3,000–3,900 ft). It rises along the Indo-Gangetic Plain and is often separated from the higher northern sub-ranges by valleys. The eastern portion of the range is called Churia Range in Nepal. The Lower or Lesser Himalaya (also known as Himachal )
