The Mackenzie Mountains are a mountain range forming part of the Yukon-Northwest Territories boundary between the Liard and Peel rivers. The range is named in honour of Canada's second prime minister, Alexander Mackenzie, as well as the explorer. Nahanni National Park Reserve and Nááts'ihch'oh National Park Reserve are in the Mackenzie Mountains; the mining town of Tungsten, site of the Cantung Mine is in the Mackenzie Mountains. Only two roads lead into the Mackenzie Mountains, both in Yukon: the Nahanni Range Road leading to the townsite of Tungsten and the Canol Road leading to the Macmillan Pass; the highest mountain in this range is Keele Peak at 2,972 m. The second highest mountain is Mount Nirvana, it is, at 2,773 m, the highest mountain in the Northwest Territories. The Silurian fish family Archipelepididae has been described from specimens found in the Mackenzie Mountains.

A normal route or normal way is the most used route for ascending and descending a mountain peak. It is the simplest route. In the Alps, routes are classed in the following ways, based on their waymarking and upkeep: Footpaths Hiking trails Mountain trails Alpine routes Climbing routes and High Alpine routes in combined rock and ice terrain, graded by difficultySometimes the normal route is not the easiest ascent to the summit, but just the one, most used. There may be technically easier variations; this is the case on the Watzmannfrau, the Hochkalter and Mount Everest. There may be many reasons these easier options are less well-used: the simplest route is less well known than the normal route; the technically easiest route is more arduous than another and is therefore used on the descent. The technically easiest route carries a much higher risk of e.g. rockfalls or avalanche and is therefore avoided in favour of a more difficult route. The technically easier route requires a complicated or long approach march, or all access may be banned via one country.
The term tourist route may sometimes be applied by those wishing to suggest that other routes up a mountain are somehow more "worthy". This belittling of the "normal route" therefore maintains a distinction between those perceiving themselves as serious mountaineers who disparage the incursion of tourist climbers into their domain
A summit is a point on a surface, higher in elevation than all points adjacent to it. The topographic terms acme, apex and zenith are synonymous; the term top is used only for a mountain peak, located at some distance from the nearest point of higher elevation. For example, a big massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are considered subsummits of the higher peak, are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may refer to the highest point along a line, trail, or route; the highest summit in the world is Everest with height of 8844.43 m above sea level. The first official ascent was made by Sir Edmund Hillary, they reached the mountain`s peak in 1953. Whether a highest point is classified as a summit, a sub peak or a separate mountain is subjective; the UIAA definition of a peak is.
Otherwise, it's a subpeak. In many parts of the western United States, the term summit refers to the highest point along a road, highway, or railroad. For example, the highest point along Interstate 80 in California is referred to as Donner Summit and the highest point on Interstate 5 is Siskiyou Mountain Summit. A summit climbing differs from the common mountaineering. Summit expedition requires: 1+ year of training, a good physical shape, a special gear. Although a huge part of climber’s stuff can be left and taken at the base camps or given to porters, there is a long list of personal equipment. In addition to common mountaineers’ gear, Summit climbers need to take Diamox and bottles of oxygen. There are special requirements for crampons, ice axe, rappel device, etc. Geoid Hill – Landform that extends above the surrounding terrain Nadir Summit accordance Peak finder Summit Climbing Gear List
The Northwest Territories is a federal territory of Canada. At a land area of 1,144,000 km2 and a 2016 census population of 41,786, it is the second-largest and the most populous of the three territories in Northern Canada, its estimated population as of 2018 is 44,445. Yellowknife became the territorial capital in 1967, following recommendations by the Carrothers Commission; the Northwest Territories, a portion of the old North-Western Territory, entered the Canadian Confederation on July 15, 1870, but the current borders were formed on April 1, 1999, when the territory was subdivided to create Nunavut to the east, via the Nunavut Act and the Nunavut Land Claims Agreement. While Nunavut is Arctic tundra, the Northwest Territories has a warmer climate and is both boreal forest, tundra, its most northern regions form part of the Canadian Arctic Archipelago; the Northwest Territories is bordered by Canada's two other territories, Nunavut to the east and Yukon to the west, by the provinces of British Columbia and Saskatchewan to the south.
The name is descriptive, adopted by the British government during the colonial era to indicate where it lay in relation to Rupert's Land. It is shortened from North-Western Territory. In Inuktitut, the Northwest Territories are referred to as ᓄᓇᑦᓯᐊᖅ, "beautiful land."There was some discussion of changing the name of the Northwest Territories after the splitting off of Nunavut to a term from an Aboriginal language. One proposal was "Denendeh", among others. One of the most popular proposals for a new name – one to name the territory "Bob" – began as a prank, but for a while it was at or near the top in the public-opinion polls. In the end, a poll conducted prior to division showed that strong support remained to keep the name "Northwest Territories"; this name arguably became more appropriate following division than it had been when the territories extended far into Canada's north-central and northeastern areas. Located in northern Canada, the territory borders Canada's two other territories, Yukon to the west and Nunavut to the east, three provinces: British Columbia to the southwest, Alberta and Saskatchewan to the south.
It meets Manitoba at a quadripoint to the extreme southeast, though surveys have not been completed. It has a land area of 1,183,085 km2. Geographical features include Great Bear Lake, the largest lake within Canada, Great Slave Lake, the deepest body of water in North America at 614 m, as well as the Mackenzie River and the canyons of the Nahanni National Park Reserve, a national park and UNESCO World Heritage Site. Territorial islands in the Canadian Arctic Archipelago include Banks Island, Borden Island, Prince Patrick Island, parts of Victoria Island and Melville Island, its highest point is Mount Nirvana near the border with Yukon at an elevation of 2,773 m. The Northwest Territories extends for more than 1,300,000 km2 and has a large climate variant from south to north; the southern part of the territory has a subarctic climate, while the islands and northern coast have a polar climate. Summers in the north are short and cool, with daytime highs of 14-17 Celsius, lows of 1-5 Celsius. Winters are long and harsh, daytime highs in the mid −20 °C and lows around −40 °C.
Extremes are common with summer highs in the south reaching 36 °C and lows reaching into the negatives. In winter in the south, it is not uncommon for the temperatures to reach −40 °C, but they can reach the low teens during the day. In the north, temperatures can reach highs of 30 °C, lows can reach into the low negatives. In winter in the north it is not uncommon for the temperatures to reach −50 °C but they can reach the single digits during the day. Thunderstorms are not rare in the south. In the north they are rare, but do occur. Tornadoes are rare but have happened with the most notable one happening just outside Yellowknife that destroyed a communications tower; the Territory has a dry climate due to the mountains in the west. About half of the territory is above the tree line. There are not many trees in the north islands; the present-day territory came under government authority in July 1870, after the Hudson's Bay Company transferred Rupert's Land and the North-Western Territory to the British Crown, which subsequently transferred them to Canada, giving it the name the North-west Territories.
This immense region comprised all of today's Canada except that, encompassed within the early signers of Canadian Confederation, that is, British Columbia, early forms of present-day Ontario and Quebec, the Maritimes, the Labrador coast, the Arctic Islands, except the southern half of Baffin Island. The first residential school opened in 1867 in Fort Resolution, followed by several others in regions across the territory, thus contributing to the Northwest Territories reaching the highest percentage of students in residential schools of any area in Canada. After the 1870 transfer, some of the North-west Territories was whittled away; the province of Manitoba was created on July 15, 1870, at first a small square area around Winnipeg
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.

Mountain peaks of Canada
This article comprises three sortable tables of major mountain peaks of Canada. The summit of a mountain or hill may be measured in three principal ways: The topographic elevation of a summit measures the height of the summit above a geodetic sea level; the first table below ranks the 100 highest major summits of Canada by elevation. The topographic prominence of a summit is a measure of how high the summit rises above its surroundings; the second table below ranks the 50 most prominent summits of Canada. The topographic isolation of a summit measures how far the summit lies from its nearest point of equal elevation; the third table below ranks the 50 most isolated major summits of Canada. Of the 100 highest major summits of Canada, five peaks exceed 5000 metres elevation, 19 peaks exceed 4000 metres, 67 peaks exceed 3000 metres, all 100 peaks equal or exceed 2706 metres elevation. Of these 100 peaks, 61 are located in British Columbia, 28 in Yukon, 13 in Alberta, one in the Northwest Territories.
Five of these peaks lie on the international border between Yukon and Alaska, four lie on the international border between British Columbia and Alaska, three lie on the border between British Columbia and Alberta, one lies on the border between British Columbia and Yukon. Of the 50 most prominent summits of Canada, only Mount Logan exceeds 4000 metres of topographic prominence, five peaks exceed 3000 metres, 41 peaks exceed 2000 metres, all 50 peaks equal or exceed 1866 metres of topographic prominence. All of these peaks are ultra-prominent summits. Of these 50 peaks, 34 are located in British Columbia, nine in Yukon, six in Nunavut, three in Alberta. Three of these peaks lie on the international border between Yukon and Alaska, one lies on the international border between British Columbia and Alaska, two lie on the border between British Columbia and Alberta, two lie on the border between British Columbia and Yukon. Of the 50 most isolated major summits of Canada, 12 peaks exceed 500 kilometres of topographic isolation, 31 peaks exceed 200 kilometres, all 50 peaks exceed 100 kilometres of topographic isolation.
Of these 50 peaks, 17 are located in British Columbia, 13 in Nunavut, seven in Yukon, four in Newfoundland and Labrador, four in Quebec, three in the Northwest Territories, two in Alberta, one each in Nova Scotia and New Brunswick. Two of these peaks lie on the international border between British Columbia and Alaska, two lie on the border between British Columbia and Alberta.

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
