A mountain range or hill range is a series of mountains or hills ranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form and alignment that have arisen from the same cause 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 found on many planetary mass objects in the Solar System and are a feature of most terrestrial planets. Mountain ranges are segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not 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, volcanic landforms resulting in 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 along the Pacific Coast, the Aleutian Range, on through Kamchatka, Taiwan, the Philippines, Papua New Guinea, to New Zealand. The Andes is 7,000 kilometres long and is considered the world's longest mountain system; the Alpide belt includes Indonesia and Southeast Asia, through the Himalaya, Caucasus Mountains, Balkan Mountains fold mountain range, the Alps, ends in the Spanish mountains and the Atlas Mountains. The belt includes other European and Asian mountain ranges; the Himalayas contain the highest mountains in the world, including Mount Everest, 8,848 metres high and traverses the border between China and Nepal. Mountain ranges outside these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Great Dividing Range, the Altai Mountains and the Hijaz Mountains. If the definition of a mountain range is stretched to include underwater mountains the Ocean Ridges form the longest continuous mountain system on Earth, with a length of 65,000 kilometres.
The mountain systems of the earth are characterized by a tree structure, where mountain ranges can contain sub-ranges. The sub-range relationship is expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains. Equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, the White Mountains and the Blue Ridge Mountains are children of the Appalachians; the parent-child expression extends to the sub-ranges themselves: the Sandwich Range and the Presidential Range are children of the White Mountains, while the Presidential Range is parent to the Northern Presidential Range and Southern Presidential Range. The position of mountains influences climate, such as snow; when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the leeward side, it warms again and is drier, having been stripped of much of its moisture.
A rain shadow will affect the leeward side of a range. Mountain ranges are subjected to erosional forces which work to tear them down; the basins adjacent to an eroding mountain range are filled with sediments which are buried and turned into sedimentary rock. Erosion 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 of 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 the east; this mass of rock was removed as the range was undergoing uplift. The removal of such a mass from the core of the range most 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, 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 are isolated and formed by processes such as impacts, though there are examples of mountain ranges somewhat similar to those on Earth. Saturn's moon Titan and Pluto, in particular exhibit large mountain ranges in chains composed of ices rather than rock. Examples include the Mithrim Montes and Doom Mons on Titan, Tenzing Montes and Hillary Montes on Pluto; some terrestrial planets other than Earth exhibit rocky mountain ranges, such as Maxwell Montes on Venus taller than any on Earth and Tartarus Montes on Mars, Jupiter's moon Io has mountain ranges formed from tectonic processes including Boösaule Montes, Dorian Montes, Hi'iaka Montes and Euboea Montes.

The Purcell Mountains are a mountain range in southeastern British Columbia, Canada. They are a subrange of the Columbia Mountains, which includes the Selkirk and Cariboo Mountains, they are located on the west side of the Rocky Mountain Trench in the area of the Columbia Valley, on the east side of the valley of Kootenay Lake and the Duncan River. The only large settlement in the mountains is the Panorama Ski Resort and Kicking Horse Resort, though there are small settlements, such as Yahk and Moyie along the Crowsnest Highway, residential rural areas dependent on the cities of Creston and Cranbrook, which are located adjacent to the range; the Purcells are shown on some United States maps as the Percell Mountains, where their southern limit protrudes into the states of Idaho and Montana, abutting Lake Koocanusa, a reservoir on the Kootenai River. American geographic classifications consider the Percells to be part of the Rocky Mountains but in Canada that terminology is reserved for ranges on the east side of the Rocky Mountain Trench.
In the Purcell Mountains, most of the peaks are above 10,000 feet in elevation. The Purcells were formed in the Proterozoic eon, which spans from 2,500 million years ago to about 540 million years ago.

British Columbia is the westernmost province of Canada, located between the Pacific Ocean and the Rocky Mountains. With an estimated population of 5.016 million as of 2018, it is Canada's third-most populous province. The first British settlement in the area was Fort Victoria, established in 1843, which gave rise to the City of Victoria, at first the capital of the separate Colony of Vancouver Island. Subsequently, on the mainland, the Colony of British Columbia was founded by Richard Clement Moody and the Royal Engineers, Columbia Detachment, in response to the Fraser Canyon Gold Rush. Moody was Chief Commissioner of Lands and Works for the Colony and the first Lieutenant Governor of British Columbia: he was hand-picked by the Colonial Office in London to transform British Columbia into the British Empire's "bulwark in the farthest west", "to found a second England on the shores of the Pacific". Moody selected the site for and founded the original capital of British Columbia, New Westminster, established the Cariboo Road and Stanley Park, designed the first version of the Coat of arms of British Columbia.
Port Moody is named after him. In 1866, Vancouver Island became part of the colony of British Columbia, Victoria became the united colony's capital. In 1871, British Columbia became the sixth province of Canada, its Latin motto is Splendor sine occasu. The capital of British Columbia remains Victoria, the fifteenth-largest metropolitan region in Canada, named for Queen Victoria, who ruled during the creation of the original colonies; the largest city is Vancouver, the third-largest metropolitan area in Canada, the largest in Western Canada, the second-largest in the Pacific Northwest. In October 2013, British Columbia had an estimated population of 4,606,371; the province is governed by the British Columbia New Democratic Party, led by John Horgan, in a minority government with the confidence and supply of the Green Party of British Columbia. Horgan became premier as a result of a no-confidence motion on June 29, 2017. British Columbia evolved from British possessions that were established in what is now British Columbia by 1871.
First Nations, the original inhabitants of the land, have a history of at least 10,000 years in the area. Today there are few treaties, the question of Aboriginal Title, long ignored, has become a legal and political question of frequent debate as a result of recent court actions. Notably, the Tsilhqot'in Nation has established Aboriginal title to a portion of their territory, as a result of the 2014 Supreme Court of Canada decision in Tsilhqot'in Nation v British Columbia; the province's name was chosen by Queen Victoria, when the Colony of British Columbia, i.e. "the Mainland", became a British colony in 1858. It refers to the Columbia District, the British name for the territory drained by the Columbia River, in southeastern British Columbia, the namesake of the pre-Oregon Treaty Columbia Department of the Hudson's Bay Company. Queen Victoria chose British Columbia to distinguish what was the British sector of the Columbia District from the United States, which became the Oregon Territory on August 8, 1848, as a result of the treaty.
The Columbia in the name British Columbia is derived from the name of the Columbia Rediviva, an American ship which lent its name to the Columbia River and the wider region. British Columbia is bordered to the west by the Pacific Ocean and the American state of Alaska, to the north by Yukon Territory and the Northwest Territories, to the east by the province of Alberta, to the south by the American states of Washington and Montana; the southern border of British Columbia was established by the 1846 Oregon Treaty, although its history is tied with lands as far south as California. British Columbia's land area is 944,735 square kilometres. British Columbia's rugged coastline stretches for more than 27,000 kilometres, includes deep, mountainous fjords and about 6,000 islands, most of which are uninhabited, it is the only province in Canada. British Columbia's capital is Victoria, located at the southeastern tip of Vancouver Island. Only a narrow strip of Vancouver Island, from Campbell River to Victoria, is populated.
Much of the western part of Vancouver Island and the rest of the coast is covered by temperate rainforest. The province's most populous city is Vancouver, at the confluence of the Fraser River and Georgia Strait, in the mainland's southwest corner. By land area, Abbotsford is the largest city. Vanderhoof is near the geographic centre of the province; the Coast Mountains and the Inside Passage's many inlets provide some of British Columbia's renowned and spectacular scenery, which forms the backdrop and context for a growing outdoor adventure and ecotourism industry. 75% of the province is mountainous. The province's mainland away from the coastal regions is somewhat moderated by the Pacific Ocean. Terrain ranges from dry inland forests and semi-arid valleys, to the range and canyon districts of the Central and Southern Interior, to boreal forest and subarctic prairie in the Northern Interior. High mountain regions both north and south subalpine climate; the Okanagan area, extending from Vernon to Osoyoos at the United States border, is one of several wine and cider-produci
Mount Sir Wilfrid Laurier
Mount Sir Wilfrid Laurier is the highest peak of the Cariboo Mountains in the east-central interior of British Columbia, Canada. The mountain is part of the Premier Range, located just west of Valemount; the name honours the seventh Prime Minister of Canada, Sir Wilfrid Laurier, who died in 1919. Named "Mount Titan" by American mountaineer Allen Carpe, it was renamed in 1929 to honour Canada's Liberal prime minister. Mountain peaks of Canada List of mountain peaks of North America
New York City
The City of New York called either New York City or New York, is the most populous city in the United States. With an estimated 2017 population of 8,622,698 distributed over a land area of about 302.6 square miles, New York is the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 20,320,876 people in its 2017 Metropolitan Statistical Area and 23,876,155 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural and media capital of the world, exerts a significant impact upon commerce, research, education, tourism, art and sports; the city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.
Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of, a separate county of the State of New York. The five boroughs – Brooklyn, Manhattan, The Bronx, Staten Island – were consolidated into a single city in 1898; the city and its metropolitan area constitute the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. New York City is home to more than 3.2 million residents born outside the United States, the largest foreign-born population of any city in the world. In 2017, the New York metropolitan area produced a gross metropolitan product of US$1.73 trillion. If greater New York City were a sovereign state, it would have the 12th highest GDP in the world. New York is home to the highest number of billionaires of any city in the world. New York City traces its origins to a trading post founded by colonists from the Dutch Republic in 1624 on Lower Manhattan.
The city and its surroundings came under English control in 1664 and were renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. New York served as the capital of the United States from 1785 until 1790, it has been the country's largest city since 1790. The Statue of Liberty greeted millions of immigrants as they came to the U. S. by ship in the late 19th and early 20th centuries and is an international symbol of the U. S. and its ideals of liberty and peace. In the 21st century, New York has emerged as a global node of creativity and entrepreneurship, social tolerance, environmental sustainability, as a symbol of freedom and cultural diversity. Many districts and landmarks in New York City are well known, with the city having three of the world's ten most visited tourist attractions in 2013 and receiving a record 62.8 million tourists in 2017. Several sources have ranked New York the most photographed city in the world. Times Square, iconic as the world's "heart" and its "Crossroads", is the brightly illuminated hub of the Broadway Theater District, one of the world's busiest pedestrian intersections, a major center of the world's entertainment industry.
The names of many of the city's landmarks and parks are known around the world. Manhattan's real estate market is among the most expensive in the world. New York is home to the largest ethnic Chinese population outside of Asia, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is the largest single-operator rapid transit system worldwide, with 472 rail stations. Over 120 colleges and universities are located in New York City, including Columbia University, New York University, Rockefeller University, which have been ranked among the top universities in the world. Anchored by Wall Street in the Financial District of Lower Manhattan, New York has been called both the most economically powerful city and the leading financial center of the world, the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. In 1664, the city was named in honor of the Duke of York.
James's older brother, King Charles II, had appointed the Duke proprietor of the former territory of New Netherland, including the city of New Amsterdam, which England had seized from the Dutch. During the Wisconsinan glaciation, 75,000 to 11,000 years ago, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth; the erosive forward movement of the ice contributed to the separation of what is now Long Island and Staten Island. That action left bedrock at a shallow depth, providing a solid foundation for most of Manhattan's skyscrapers. In the precolonial era, the area of present-day New York City was inhabited by Algonquian Native Americans, including the Lenape, whose homeland, known as Lenapehoking, included Staten Island; the first documented visit into New York Harbor by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown. He named it Nouvelle Angoulême. A Spanish expedition led by captain Estêvão Gomes, a Portuguese sailing for Emperor Charles V, arrived in New York Harbor in January 1525 and charted the mouth of the Hudson River, which he named Río de San Antonio.

The Bugaboos are a mountain range in the Purcell Mountains of eastern British Columbia, Canada. The granite spires of the group are a popular mountaineering destination; the Bugaboos are protected within Bugaboo Provincial Park. The Bugaboos are located in the northwestern extreme of the Purcells in the Columbia Mountains, in the south-east of the province; the nearest towns are Golden. They are subdivided into four divisions: the Bugaboo Glacier Peaks, the Eastern and Western Spires; the nearby Vowell and Conrad Groups are considered separate from the Bugaboos. Located in the snow- and rain-heavy "Columbia Wet Belt", this section of the Purcells is subject to heavy erosion and large, active glaciers. Covered in weaker rock, glaciation revealed the granodiorite batholiths which form the group's distinctive spires; the surrounding rock is 600 million to 1 billion years old, while the Bugaboo intrusion dates to 135 million years ago. The igneous intrusion cooled forming the crystalline structure of the hard granite found today.
Named the "Nunataks", the Bugaboo spires were first noted by a surveying expedition in the late 1800s. Mining brought the first Europeans to the region with a small, ill-fated gold rush occurring in 1895 and 1896 near Bugaboo Falls; the area was prospected and staked, but the meager deposits turned out to be pyrite and galena. The name "Bugaboo" originated from this rush. Climbers became interested in the group shortly after. In 1910, an expedition led by Thomas Longstaff and surveyor Arthur Oliver Wheeler entered the area, they were guided by renowned European climber Conrad Kain. Kain would return to the area six years and pioneer many difficult climbing routes; the Austrian climber described his route up Bugaboo Spire as his most difficult Canadian ascent, more challenging than his celebrated route up Mount Robson, the highest peak in the Canadian Rockies. Along with Albert and Bess McCarthy and others, Kain would pioneer first ascents of North Howser and Crescent Spires. Logging in the area resulted in road construction in the 1950s and 60s.
This led to a new influx of climbers. Fred Beckey and Yvon Chouinard established new routes on several spires; the growing popularity of the area led the BC government to establish Bugaboo Glacier Provincial Park and the Bugaboo Alpine Recreation Area in 1969. The Alpine Club of Canada constructed a large hut in 1972 to reduce environmental damage to the fragile alpine meadows below the spires; the Bugaboos have several internationally known rock climbing routes. The Beckey-Chouinard, West Ridge, Northeast Ridge and Surf's Up attract world-class climbers. There are both free routes throughout the group. Climbers and hikers use the 40-person Conrad Kain hut, maintained by the Alpine Club of Canada. Located near Snowpatch Spire, the hut replaced; the Bugaboo Lodge, constructed in 1967, is near the eastern boundary of the park. Heli-skiing and heli-hiking are conducted from the lodge into the park. Ski touring is popular in the group during the winter.

BC Geographical Names
In modern mapping, a topographic map is a type of map characterized by large-scale detail and quantitative representation of relief using contour lines, but using a variety of methods. Traditional definitions require a topographic map to show both man-made features. A topographic survey is published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a line connecting places of equal elevation. Natural Resources Canada provides this description of topographic maps:These maps depict in detail ground relief, forest cover, administrative areas, populated areas, transportation routes and facilities, other man-made features. Other authors define topographic maps by contrasting them with another type of map. However, in the vernacular and day to day world, the representation of relief is popularly held to define the genre, such that small-scale maps showing relief are called "topographic"; the study or discipline of topography is a much broader field of study, which takes into account all natural and man-made features of terrain.
Topographic maps are based on topographical surveys. Performed at large scales, these surveys are called topographical in the old sense of topography, showing a variety of elevations and landforms; this is in contrast to older cadastral surveys, which show property and governmental boundaries. The first multi-sheet topographic map series of an entire country, the Carte géométrique de la France, was completed in 1789; the Great Trigonometric Survey of India, started by the East India Company in 1802 taken over by the British Raj after 1857 was notable as a successful effort on a larger scale and for determining heights of Himalayan peaks from viewpoints over one hundred miles distant. Topographic surveys were prepared by the military to assist in planning for battle and for defensive emplacements; as such, elevation information was of vital importance. As they evolved, topographic map series became a national resource in modern nations in planning infrastructure and resource exploitation. In the United States, the national map-making function, shared by both the Army Corps of Engineers and the Department of the Interior migrated to the newly created United States Geological Survey in 1879, where it has remained since.1913 saw the beginning of the International Map of the World initiative, which set out to map all of Earth's significant land areas at a scale of 1:1 million, on about one thousand sheets, each covering four degrees latitude by six or more degrees longitude.
Excluding borders, each sheet was up to 66 cm wide. Although the project foundered, it left an indexing system that remains in use. By the 1980s, centralized printing of standardized topographic maps began to be superseded by databases of coordinates that could be used on computers by moderately skilled end users to view or print maps with arbitrary contents and scale. For example, the Federal government of the United States' TIGER initiative compiled interlinked databases of federal and local political borders and census enumeration areas, of roadways and water features with support for locating street addresses within street segments. TIGER was used in the 1990 and subsequent decennial censuses. Digital elevation models were compiled from topographic maps and stereographic interpretation of aerial photographs and from satellite photography and radar data. Since all these were government projects funded with taxes and not classified for national security reasons, the datasets were in the public domain and usable without fees or licensing.
TIGER and DEM datasets facilitated Geographic information systems and made the Global Positioning System much more useful by providing context around locations given by the technology as coordinates. Initial applications were professionalized forms such as innovative surveying instruments and agency-level GIS systems tended by experts. By the mid-1990s user-friendly resources such as online mapping in two and three dimensions, integration of GPS with mobile phones and automotive navigation systems appeared; as of 2011, the future of standardized, centrally printed topographical maps is left somewhat in doubt. Topographic maps have multiple uses in the present day: any type of geographic planning or large-scale architecture; the various features shown on the map are represented by conventional symbols. For example, colors can be used to indicate a classification of roads; these signs are explained in the margin of the map, or on a separately published characteristic sheet. Topographic maps are commonly called contour maps or topo maps.
In the United States, where the primary national series is organized by a strict 7.5-minute grid, they are called topo quads or quadrangles. Topographic maps conventionally show land contours, by means of contour lines. Contour lines are curves. In other words, every point on the marked line of 100 m elevation is 100 m above mean sea level; these maps show
