76-543: According to Ken Gwertz's article "Landscape Alchemist," George Hargreaves' interest in Landscape Architecture was partially due to a summer trip that he went on when he was 18 years old. During the trip to the Rocky Mountains , George Hargreaves climbed Flat Top Mountain where he experienced a life changing scene. Hargreaves describes the sense, "It wasn't just the mountains or the trees or any of

152-585: 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

228-547: A master's degree in Landscape Architecture. In 1983, Hargreaves Associates , now Hargreaves Jones, was founded. George and Hargreaves Associates have worked on many well known designs over the years. George Hargreaves is an important part of every design. Hargreaves Jones (previously Hargreaves Associates) is a professional consulting firm composed of landscape architects and planners with offices in San Francisco, California, and Cambridge, Massachusetts. The work includes

304-523: 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

380-893: 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

456-623: A tenured professor and continued teaching there for over twenty years. He was the chair for the Department of Landscape Architecture from 1996 through 2003. Prior to resigning from his position at Harvard to focus on his practice, he was the Peter Louis Hornbeck Professor in Practice of Landscape Architecture and taught advanced and theoretical design classes and core studios. An important piece of his academic work

532-843: A variety of rock types . Most geologically young mountain ranges on the Earth's land surface are associated with either the Pacific Ring of Fire or the Alpide belt . The Pacific Ring of Fire includes the Andes of South America, extends through the North American Cordillera , the Aleutian Range , on through Kamchatka Peninsula , Japan , Taiwan , the Philippines , Papua New Guinea , to New Zealand . The Andes

608-525: A wide range of urban design, waterfronts, public parks, academic, corporate, institutional, and residential planning and design projects. According to Hargreaves, "Convention is easy to slip into, to keep making the same pictures. What I try to find are those magic moments of clarity when you hear what the site is whispering to you." Landscape Alchemist In the Introduction of the 2009 publication on his practice, Landscape Alchemy , Hargreaves cites that

684-722: Is 7,000 kilometres (4,350 mi) long and is often considered the world's longest mountain system. The Alpide belt stretches 15,000 km across southern Eurasia , from Java in Maritime Southeast Asia to the Iberian Peninsula in Western Europe , including the ranges of the Himalayas , Karakoram , Hindu Kush , Alborz , Caucasus , and the Alps . The Himalayas contain the highest mountains in

760-432: Is a continuing search for the way to conceptually enter the site and create bones where there are none”, and that while each Hargreaves project integrates sustainability, phenomena and process, site histories, adjacencies and overlays, “none should operate singularly - they all interact on the same site as we strive to put bones in our projects that will give them life for decades or centuries to come”. At his presentation to

836-476: Is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny . Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics . Mountain ranges are also found on many planetary mass objects in

912-474: Is at work while the mountains are being uplifted until the mountains are reduced to low hills and plains. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example. As the uplift was occurring some 10,000 feet (3,000 m) of mostly Mesozoic sedimentary strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to

988-531: Is drier, having been stripped of much of its moisture. Often, a rain shadow will affect the leeward side of a range. As a consequence, large mountain ranges, such as the Andes, compartmentalize continents into distinct climate regions . Mountain ranges are constantly subjected to erosional forces which work to tear them down. The basins adjacent to an eroding mountain range are then filled with sediments that are buried and turned into sedimentary rock . Erosion

1064-794: 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

1140-706: 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

1216-498: Is the book he co-wrote with Julia Czerniak . The book is Large Parks . Large Parks is compilation of eight essays on large urban parks. These essays talk about the complexity of the parks and how they are a part of society. Large Parks is only the latest in a long line of publications that he has written and was awarded the J. B. Jackson Book Prize by the Foundation for Landscape Studies for having contributed significantly to

1292-668: The 49th parallel north as the international boundary west from Lake of the Woods to the "Stony Mountains"; the UK and the US agreed to what has since been described as "joint occupancy" of lands further west to the Pacific Ocean. 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

1368-479: 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

1444-547: 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

1520-810: 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

1596-709: 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

1672-608: 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

1748-902: The Canadian Rockies . The eastern edge of the Rockies rises dramatically above the Interior Plains of central North America, including the Sangre de Cristo Mountains of New Mexico and Colorado , the Front Range of Colorado, the Wind River Range and Big Horn Mountains of Wyoming , the Absaroka - Beartooth ranges and Rocky Mountain Front of Montana and the Clark Range of Alberta . Central ranges of

1824-507: The Climax mine, near Leadville, Colorado , was the largest producer of molybdenum in the world. Molybdenum is used in heat-resistant steel in such things as cars and planes. The Climax mine employed over 3,000 workers. The Coeur d'Alene mine of northern Idaho produces silver, lead, and zinc. Canada's largest coal mines are near Fernie, British Columbia and Sparwood , British Columbia; additional coal mines exist near Hinton, Alberta , and in

1900-769: The Columbia District for Britain. The party crossed the Rockies into the Columbia Valley , a region of the Rocky Mountain Trench near present-day Radium Hot Springs , British Columbia, then traveled south. Despite such efforts, in 1846, Britain ceded all claim to Columbia District lands south of the 49th parallel to the United States; as resolution to the Oregon boundary dispute by the Oregon Treaty . Thousands passed through

1976-513: 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

2052-676: The Liard River and east of the Rocky Mountain Trench , and do not extend into Yukon , Northwest Territories or central British Columbia . They are divided into three main groups: the Muskwa Ranges , Hart Ranges (collectively called the Northern Rockies ) and Continental Ranges . Other more northerly mountain ranges of the eastern Canadian Cordillera continue beyond the Liard River valley, including

2128-515: The North American plate . The angle of subduction was shallow, resulting in a broad belt of mountains running down western North America. Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks and valleys. At the end of the last ice age , humans began inhabiting the mountain range. After explorations of the range by Europeans, such as Sir Alexander Mackenzie , and Anglo-Americans, such as

2204-473: The Ocean Ridge forms the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi). The position of mountain ranges influences climate, such as rain or snow. When air masses move up and over mountains, the air cools, producing orographic precipitation (rain or snow). As the air descends on the leeward side, it warms again (following the adiabatic lapse rate ) and

2280-644: The Paleozoic , western North America lay underneath a shallow sea, which deposited many kilometers of limestone and dolomite . In the southern Rockies, near present-day Colorado, these ancestral rocks were disturbed by mountain building approximately 300 Ma , during the Pennsylvanian . This mountain-building produced the Ancestral Rocky Mountains. They consisted largely of Precambrian metamorphic rock forced upward through layers of

2356-645: 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

2432-536: The Rio Grande rift and north of the Sandia–Manzano Mountain Range . Being the easternmost portion of the North American Cordillera , the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada , which both lie farther to its west. The Rockies formed 55 million to 80 million years ago during the Laramide orogeny , in which a number of plates began sliding underneath

2508-682: 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

2584-818: The Selwyn , Mackenzie and Richardson Mountains in Yukon as well as the British Mountains / Brooks Range in Alaska , but those are not officially recognized as part of the Rockies by the Geological Survey of Canada , although the Geological Society of America definition does consider them parts of the Rocky Mountains system as the "Arctic Rockies". The Continental Divide of the Americas

2660-459: The Solar System and are likely a feature of most terrestrial planets . Mountain ranges are usually segmented by highlands or mountain passes and valleys . Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology . They may be a mix of different orogenic expressions and terranes , for example thrust sheets , uplifted blocks , fold mountains, and volcanic landforms resulting in

2736-430: 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

2812-535: The "Rockies", becoming the first Europeans to report on this uncharted mountain range. Sir Alexander Mackenzie (1764 – March 11, 1820) became the first European to cross the Rocky Mountains in 1793. He found the upper reaches of the Fraser River and reached the Pacific coast of what is now Canada on July 20 of that year, completing the first recorded transcontinental crossing of North America north of Mexico. He arrived at Bella Coola, British Columbia , where he first reached saltwater at South Bentinck Arm, an inlet of

2888-467: The Ancestral Rocky Mountains. Such sedimentary remnants were often tilted at steep angles along the flanks of the modern range; they are now visible in many places throughout the Rockies, and are shown along the Dakota Hogback , an early Cretaceous sandstone formation running along the eastern flank of the modern Rockies. Just after the Laramide orogeny, the Rockies were like Tibet : a high plateau, probably 6,000 metres (20,000 ft) above sea level. In

2964-427: The California and Alaska gold rushes combined and was important in the financing of the Union Army during the American Civil War . The transcontinental railroad was completed in 1869, and Yellowstone National Park was established as the world's first national park in 1872. Meanwhile, a transcontinental railroad in Canada was originally promised in 1871. Though political complications pushed its completion to 1885,

3040-614: The Forum for Urban Design Spring Conference 2009: the 21st Century Park & Contemporary City held at the Modern Museum of Art, Hargreaves emphasized that "distressed sites, whether abandoned, polluted, neglected, or all three, are the dross from which 21st Century dreams are woven". George Hargreaves started his academic career shortly after he started Hargreaves Associates. He first taught at universities such as Cal Poly , University of Illinois Champaign , and University of Virginia Charlottesville . In 1986, George began to teach at Harvard University Graduate School of Design where he became

3116-430: The Native American cultures. 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

3192-529: 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

3268-492: 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

3344-454: 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

3420-423: 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

3496-464: 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

3572-410: 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

3648-485: 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

3724-442: 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

3800-436: 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

3876-404: 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

Its southernmost point is near the Albuquerque area adjacent to

4028-433: 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

4104-501: 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

4180-428: 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

4256-451: 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

4332-485: The east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive,

4408-417: 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,

4484-582: The firm seldom encounters project sites that are a greenfield or “natural” but are more likely to be brownfields, often flat, devoid of any significant vegetation or other natural features, yet close to city centers. Mostly late 20th century and early 21st century sites, they differ greatly from the majority of the sites for the great parks realized from the 17th to early 20th century that had much more obvious character where glacial terrain with remnant countryside provided what Hargreaves likes to call “good bones”. Additionally, he points out that “our design strategies

4560-510: 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 ).

When I got back home I tried to explain this to my uncle...and he said, 'Have you ever thought about going into landscape architecture?'" In 1973, George Hargreaves attended the School of Environment and Design at the University of Georgia . Four years later, he graduated second in his class, magna cum laude, with a Bachelor of Landscape Architecture . Soon after getting his bachelor's degree, George went to Harvard University Graduate School of Design . He graduated with distinction and received

4788-469: 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

4864-406: 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

4940-456: 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

5016-425: 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

5092-450: 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

5168-484: 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

5244-478: 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

5320-516: The rate of erosion drops because there are fewer abrasive particles in the water and fewer landslides. Mountains on other planets and natural satellites of the Solar System, including the Moon , are often isolated and formed mainly by processes such as impacts, though there are examples of mountain ranges (or "Montes") somewhat similar to those on Earth. Saturn 's moon Titan and Pluto , in particular, exhibit large mountain ranges in chains composed mainly of ices rather than rock. Examples include

5396-618: 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

5472-494: 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,

5548-655: 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
