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
The Alaska Highway was constructed during World War II for the purpose of connecting the contiguous United States to Alaska across Canada. It begins at the junction with several Canadian highways in Dawson Creek, British Columbia, runs to Delta Junction, via Whitehorse, Yukon. Completed in 1942 at a length of 1,700 miles, as of 2012 it is 1,387 mi long; the difference in distance is due to constant reconstruction of the highway, which has rerouted and straightened out numerous sections. The highway was opened to the public in 1948. Legendary over many decades for being a rough, challenging drive, the highway is now paved over its entire length, its component highways are British Columbia Highway 97, Yukon Highway 1 and Alaska Route 2. An informal system of historic mileposts developed over the years to denote major stopping points, it is at this point that the Alaska Highway meets the Richardson Highway, which continues 96 mi to the city of Fairbanks. This is regarded, though unofficially, as the northern portion of the Alaska Highway, with Fairbanks at Historic Milepost 1520.
Mileposts on this stretch of highway are measured from Valdez, rather than the Alaska Highway. The Alaska Highway is popularly considered part of the Pan-American Highway, which extends south to Argentina. Proposals for a highway to Alaska originated in the 1920s. Thomas MacDonald, director of the U. S. Bureau of Public Roads, dreamed of an international highway spanning the United States and Canada. In order to promote the highway, Slim Williams traveled the proposed route by dogsled. Since much of the route would pass through Canada, support from the Canadian government was crucial. However, the Canadian government perceived no value in putting up the required funds to build the road, since the only part of Canada that would benefit was not more than a few thousand people in Yukon. In 1929 the British Columbia government proposed a highway to Alaska to encourage economic development and tourism. American President Herbert Hoover appointed a board with American and three Canadian members to evaluate the idea.
Its 1931 report supported the idea for economic reasons, but both American and Canadian members recognized that a highway would benefit the American military in Alaska. In 1933, the joint commission proposed the U. S. government contribute $2 million of the capital cost, with the $12 million balance borne by the Canadian and BC governments. The Great Depression and the Canadian government's lack of support caused the project to not proceed; when the United States approached Canada again in February 1936, the Canadian government refused to commit to spending money on a road connecting the United States. The Canadians worried about the military implications, fearing that in a war between Japan and North America, the United States would use the road to prevent Canadian neutrality. During a June 1936 visit to Canada, President Franklin D. Roosevelt told Prime Minister W. L. M. King that a highway to Alaska through Canada could be important in reinforcing the American territory during a foreign crisis.
Roosevelt became the first American to publicly discuss the military benefits of a highway in an August speech in Chautauqua, New York. He again mentioned the idea during King's visit to Washington in March 1937, suggesting that a $30 million highway would be helpful as part of a larger defense against Japan that included, the Americans hoped, a larger Canadian military presence on the Pacific coast. Roosevelt remained a supporter of the highway, telling Cordell Hull in August 1937 that he wanted a road built as soon as possible. By 1938, Duff Pattullo, the BC premier, favored a route through Prince George; the U. S. offered either a $15 million interest-free loan. The attack on Pearl Harbor and beginning of the Pacific Theater in World War II, coupled with Japanese threats to the west coast of North America and the Aleutian Islands, changed the priorities for both nations. On February 6, 1942, the construction of the Alaska Highway was approved by the United States Army and the project received the authorization from the U.
S. Congress and Roosevelt to proceed five days later. Canada agreed to allow construction as long as the United States bore the full cost, that the road and other facilities in Canada be turned over to Canadian authority after the war ended, it proved unimportant for the military because 99 percent of the supplies to Alaska during the war were sent by sea from San Francisco and Prince Rupert. The Americans preferred Route A, which starting at Prince George, went northwest to Hazelton, along the Stikine River, by Atlin and Tabish Lakes, from Whitehorse, Yukon to Fairbanks, Alaska via the Tanana Valley. However, the route was vulnerable to possible enemy attack from the sea, experienced steep grades, heavy snowfall and there were no airbases along the way; the Canadians favored Route B starting at Prince George, but followed the Rocky Mountain Trench up the valleys of the Parsnip and Finlay Rivers to Finlay Forks and Sifton Pass north to Frances Lake and the Pelly River in the Yukon. From there it went to Dawson City and down the Yukon Valley to connect the Richardson Highway to Fairbanks.
The advantages of this inland route was the safe distance from enemy planes, 209 miles shorter with lower elevations enabling lower construction and maintenance costs. The disadvantages were the bypassing of respective airbases, Whitehorse, the principal town in the Yukon. Optional variations in the southern p
Denali National Park and Preserve
Denali National Park and Preserve is an American national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres, larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, glaciers and bare rock at the highest elevations; the longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, snowmobiling; the park received 594,660 recreational visitors in 2018. Human habitation in the Denali Region extends to more than 11,000 years before the present, with documented sites just outside park boundaries dated to more than 8,000 years before present; however few archaeological sites have been documented within the park boundaries, owing to the region's high elevation, with harsh winter conditions and scarce resources compared to lower elevations in the area.
The oldest site within park boundaries is the Teklanika River site, dated to about 7130 BC. More than 84 archaeological sites have been documented within the park; the sites are characterized as hunting camps rather than settlements, provide little cultural context. The presence of Athabaskan peoples in the region is dated to 1,500 - 1,000 years before present on linguistic and archaeological evidence, while researchers have proposed that Athabaskans may have inhabited the area for thousands of years before then; the principal groups in the park area in the last 500 years include the Koyukon and Dena'ina people. Other prehistoric finds include Mesozoic fossils from the Denali Region. Studies of fossil plants from the same formation indicate the area was wet, with marshes and ponds throughout the region. In 1906, conservationist Charles Alexander Sheldon conceived the idea of preserving the Denali region as a national park, he presented the plan to his co-members of the Crockett Club. They decided that the political climate at the time was unfavorable for congressional action, that the best hope of success rested on the approval and support from the Alaskans themselves.
Sheldon wrote, "The first step was to secure the approval and cooperation of the delegate who represented Alaska in Congress."In October 1915, Sheldon took up the matter with Dr. E. W. Nelson of the Biological Survey at Washington, D. C. and with George Bird Grinnell, with a purpose to introduce a suitable bill in the coming session of Congress. The matter was taken to the Game Committee of the Boone and Crockett Club and, after a full discussion, it received the committee's full endorsement. On December 3, 1915, the plan was presented to Alaska's delegate, James Wickersham, who after some deliberation gave his approval; the plan went to the Executive Committee of the Boone and Crockett Club and, on December 15, 1915, it was unanimously accepted. The plan was thereupon endorsed by the Club and presented to Stephen Mather, Assistant Secretary of the Interior in Washington, D. C. who approved it. The bill was introduced in April, 1916, by Delegate Wickersham in the House and by Senator Key Pittman of Nevada in the Senate.
Much lobbying took place over the following year, on February 19, 1917, the bill passed. On February 26, 1917, 11 years from its conception, the bill was signed in legislation by the President of the United States, Woodrow Wilson, thereby creating Mount McKinley National Park. A portion of Denali, excluding the summit, was included the original park boundary. On Thanksgiving Day in 1921, the Mount McKinley Park Hotel opened. In July 1923, President Warren Harding stopped at the hotel, on a tour of the length of the Alaska Railroad, during which he drove a golden spike signaling its completion at Nenana; the hotel was the first thing. The flat-roofed, two-story log building featured exposed balconies, glass windows, electric lights. Inside were two dozen guest rooms, a shop, lunch counter and storeroom. By the 1930s, there were reports of lice, dirty linen, drafty rooms, marginal food, which led to the hotel's closing. In 1947, the park boundaries expanded to include the area of the railroad. After being abandoned for many years, the hotel was destroyed in 1950 by a fire.
There was no road access to the park entrance until 1957. Now with a highway connection to Anchorage and Fairbanks, park attendance expanded: there were 5,000 visitors in 1956 and 25,000 visitors by 1958; the park was designated an international biosphere reserve in 1976. A separate Denali National Monument was proclaimed by President Jimmy Carter on December 1, 1978; the name of Mount McKinley National Park was subject to local criticism from the beginning of the park. The word Denali means "the high one" in the native Athabaskan language and refers to the mountain itself; the mountain was named after newly elected US president William McKinley in 1897 by local prospector William A. Dickey; the United States government formally adopted the name Mount McKinley after President Wilson signed the bill creating Mount McKinley National Park into effect in 1917. In 1980, Mount McKinley National Park was combined with Denali National Monument, the Alaska National Interest Lands Conservation Act named the combined unit the Denali National Park and Preserve.
At that time the Alaska state Board of Geographic Names changed
Binomial nomenclature called binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomen, binominal name or a scientific name; the first part of the name – the generic name – identifies the genus to which the species belongs, while the second part – the specific name or specific epithet – identifies the species within the genus. For example, humans belong within this genus to the species Homo sapiens. Tyrannosaurus rex is the most known binomial; the formal introduction of this system of naming species is credited to Carl Linnaeus beginning with his work Species Plantarum in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book Pinax theatri botanici many names of genera that were adopted by Linnaeus; the application of binomial nomenclature is now governed by various internationally agreed codes of rules, of which the two most important are the International Code of Zoological Nomenclature for animals and the International Code of Nomenclature for algae and plants.
Although the general principles underlying binomial nomenclature are common to these two codes, there are some differences, both in the terminology they use and in their precise rules. In modern usage, the first letter of the first part of the name, the genus, is always capitalized in writing, while that of the second part is not when derived from a proper noun such as the name of a person or place. Both parts are italicized when a binomial name occurs in normal text, thus the binomial name of the annual phlox is now written as Phlox drummondii. In scientific works, the authority for a binomial name is given, at least when it is first mentioned, the date of publication may be specified. In zoology "Patella vulgata Linnaeus, 1758"; the name "Linnaeus" tells the reader who it was that first published a description and name for this species of limpet. "Passer domesticus". The original name given by Linnaeus was Fringilla domestica; the ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, although nomenclatorial catalogs include such information.
In botany "Amaranthus retroflexus L." – "L." is the standard abbreviation used in botany for "Linnaeus". "Hyacinthoides italica Rothm. – Linnaeus first named this bluebell species Scilla italica. The name is composed of two word-forming elements: "bi", a Latin prefix for two, "-nomial", relating to a term or terms; the word "binomium" was used in Medieval Latin to mean a two-term expression in mathematics. Prior to the adoption of the modern binomial system of naming species, a scientific name consisted of a generic name combined with a specific name, from one to several words long. Together they formed a system of polynomial nomenclature; these names had two separate functions. First, to designate or label the species, second, to be a diagnosis or description. In a simple genus, containing only two species, it was easy to tell them apart with a one-word genus and a one-word specific name; such "polynomial names" may sometimes look like binomials, but are different. For example, Gerard's herbal describes various kinds of spiderwort: "The first is called Phalangium ramosum, Branched Spiderwort.
The other... is aptly termed Phalangium Ephemerum Virginianum, Soon-Fading Spiderwort of Virginia". The Latin phrases are short descriptions, rather than identifying labels; the Bauhins, in particular Caspar Bauhin, took some important steps towards the binomial system, by pruning the Latin descriptions, in many cases to two words. The adoption by biologists of a system of binomial nomenclature is due to Swedish botanist and physician Carl von Linné, more known by his Latinized name Carl Linnaeus, it was in his 1753 Species Plantarum that he first began using a one-word "trivial name" together with a generic name in a system of binomial nomenclature. This trivial name is what is now known as specific name; the Bauhins' genus names were retained in many of these, but the descriptive part was reduced to a single word. Linnaeus's trivial names introduced an important new idea, namely that the function of a name could be to give a species a unique label; this meant. Thus Gerard's Phalangium ephemerum virginianum became Tradescantia virgi
Eutheria is one of two mammalian clades with extant members that diverged in the Early Cretaceous or the Late Jurassic. Except for the Virginia opossum, from North America, a metatherian, all post-Miocene mammals indigenous to Europe, Africa and North America north of Mexico are eutherians. Extant eutherians, their last common ancestor, all extinct descendants of that ancestor are members of Placentalia. Eutherians are distinguished from noneutherians by various phenotypic traits of the feet, ankles and teeth. All extant eutherians lack epipubic bones; this allows for expansion of the abdomen during pregnancy. The oldest-known eutherian species is Juramaia sinensis, dated at 161 million years ago from the Jurassic in China. Eutheria was named in 1872 by Theodore Gill. Distinguishing features are: an enlarged malleolus at the bottom of the tibia, the larger of the two shin bones the joint between the first metatarsal bone and the entocuneiform bone in the foot is offset farther back than the joint between the second metatarsal and middle cuneiform bones—in metatherians these joints are level with each other various features of jaws and teeth Eutheria contains several extinct genera as well as larger groups, many with complicated taxonomic histories still not understood.
Members of the Adapisoriculidae and Leptictida have been placed within the out-dated placental group Insectivora, while Zhelestids have been considered primitive ungulates. However, more recent studies have suggested these enigmatic taxa represent stem group eutherians, more basal to Placentalia; the weakly favoured cladogram favours Boreoeuthearia as a basal Eutherian clade as sister to the Atlantogenata
North America is a continent within the Northern Hemisphere and all within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, to the southeast by South America and the Caribbean Sea. North America covers an area of about 24,709,000 square kilometers, about 16.5% of the earth's land area and about 4.8% of its total surface. North America is the third largest continent by area, following Asia and Africa, the fourth by population after Asia and Europe. In 2013, its population was estimated at nearly 579 million people in 23 independent states, or about 7.5% of the world's population, if nearby islands are included. North America was reached by its first human populations during the last glacial period, via crossing the Bering land bridge 40,000 to 17,000 years ago; the so-called Paleo-Indian period is taken to have lasted until about 10,000 years ago. The Classic stage spans the 6th to 13th centuries.
The Pre-Columbian era ended in 1492, the transatlantic migrations—the arrival of European settlers during the Age of Discovery and the Early Modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, African slaves and their descendants. Owing to the European colonization of the Americas, most North Americans speak English, Spanish or French, their culture reflects Western traditions; the Americas are accepted as having been named after the Italian explorer Amerigo Vespucci by the German cartographers Martin Waldseemüller and Matthias Ringmann. Vespucci, who explored South America between 1497 and 1502, was the first European to suggest that the Americas were not the East Indies, but a different landmass unknown by Europeans. In 1507, Waldseemüller produced a world map, in which he placed the word "America" on the continent of South America, in the middle of what is today Brazil, he explained the rationale for the name in the accompanying book Cosmographiae Introductio:... ab Americo inventore... quasi Americi terram sive Americam.
For Waldseemüller, no one should object to the naming of the land after its discoverer. He used the Latinized version of Vespucci's name, but in its feminine form "America", following the examples of "Europa", "Asia" and "Africa". Other mapmakers extended the name America to the northern continent, In 1538, Gerard Mercator used America on his map of the world for all the Western Hemisphere; some argue that because the convention is to use the surname for naming discoveries, the derivation from "Amerigo Vespucci" could be put in question. In 1874, Thomas Belt proposed a derivation from the Amerrique mountains of Central America. Marcou corresponded with Augustus Le Plongeon, who wrote: "The name AMERICA or AMERRIQUE in the Mayan language means, a country of perpetually strong wind, or the Land of the Wind, and... the can mean... a spirit that breathes, life itself." The United Nations formally recognizes "North America" as comprising three areas: Northern America, Central America, The Caribbean.
This has been formally defined by the UN Statistics Division. The term North America maintains various definitions in accordance with context. In Canadian English, North America refers to the land mass as a whole consisting of Mexico, the United States, Canada, although it is ambiguous which other countries are included, is defined by context. In the United States of America, usage of the term may refer only to Canada and the US, sometimes includes Greenland and Mexico, as well as offshore islands. In France, Portugal, Romania and the countries of Latin America, the cognates of North America designate a subcontinent of the Americas comprising Canada, the United States, Mexico, Greenland, Saint Pierre et Miquelon, Bermuda. North America has been referred to by other names. Spanish North America was referred to as Northern America, this was the first official name given to Mexico. Geographically the North American continent has many subregions; these include cultural and geographic regions. Economic regions included those formed by trade blocs, such as the North American Trade Agreement bloc and Central American Trade Agreement.
Linguistically and culturally, the continent could be divided into Latin America. Anglo-America includes most of Northern America and Caribbean islands with English-speaking populations; the southern North American continent is composed of two regions. These are the Caribbean; the north of the continent maintains recognized regions as well. In contrast to the common definition of "North America", which encompasses the whole continent, the term "North America" is sometimes used to refer only to Mexico, the United States, Greenland; the term Northern America refers to the northern-most countries and territories of North America: the United States, Bermuda, St. Pierre and Miquelon and Greenland. Although the term does not refer to a unifie
The coyote, Canis latrans, is a canine native to North America. It is smaller than its close relative, the gray wolf, smaller than the related eastern wolf and red wolf, it fills much of the same ecological niche as the golden jackal does in Eurasia, though it is larger and more predatory, is sometimes called the American jackal by zoologists. The coyote is listed as least concern by the International Union for Conservation of Nature due to its wide distribution and abundance throughout North America, southwards through Mexico, into Central America; the species is able to adapt to and expand into environments modified by humans. It is enlarging its range, with coyotes moving into urban areas in the Eastern U. S. and was sighted in eastern Panama for the first time in 2013. As of 2005, 19 coyote subspecies are recognized; the average male weighs the average female 7 to 18 kg. Their fur color is predominantly light gray and red or fulvous interspersed with black and white, though it varies somewhat with geography.
It is flexible in social organization, living either in a family unit or in loosely knit packs of unrelated individuals. It has a varied diet consisting of animal meat, including deer, hares, birds, amphibians and invertebrates, though it may eat fruits and vegetables on occasion, its characteristic vocalization is a howl made by solitary individuals. Humans are the coyote's greatest threat, followed by gray wolves. In spite of this, coyotes sometimes mate with gray, eastern, or red wolves, producing "coywolf" hybrids. In the northeastern United States and eastern Canada, the eastern coyote is the result of various historical and recent matings with various types of wolves. Genetic studies show that most North American wolves contain some level of coyote DNA; the coyote is a prominent character in Native American folklore in the Southwestern United States and Mexico depicted as a trickster that alternately assumes the form of an actual coyote or a man. As with other trickster figures, the coyote uses deception and humor to rebel against social conventions.
The animal was respected in Mesoamerican cosmology as a symbol of military might. After the European colonization of the Americas, it was reviled in Anglo-American culture as a cowardly and untrustworthy animal. Unlike wolves, which have undergone an improvement of their public image, attitudes towards the coyote remain negative. Coyote males average 8 to 20 kg in weight, while females average 7 to 18 kg, though size varies geographically. Northern subspecies, which average 18 kg, tend to grow larger than the southern subspecies of Mexico, which average 11.5 kg. Body length ranges on average from 1.0 to 1.35 m, tail length 40 cm, with females being shorter in both body length and height. The largest coyote on record was a male killed near Afton, Wyoming, on November 19, 1937, which measured 1.5 m from nose to tail, weighed 34 kg. Scent glands are a bluish-black color; the color and texture of the coyote's fur varies somewhat geographically. The hair's predominant color is light gray and red or fulvous, interspersed around the body with black and white.
Coyotes living at high elevations tend to have more black and gray shades than their desert-dwelling counterparts, which are more fulvous or whitish-gray. The coyote's fur consists of soft underfur and long, coarse guard hairs; the fur of northern subspecies is longer and denser than in southern forms, with the fur of some Mexican and Central American forms being hispid. Adult coyotes have a sable coat color, dark neonatal coat color, bushy tail with an active supracaudal gland, a white facial mask. Albinism is rare in coyotes; the coyote is smaller than the gray wolf, but has longer ears and a larger braincase, as well as a thinner frame and muzzle. The scent glands are the same color, its fur color variation is much less varied than that of a wolf. The coyote carries its tail downwards when running or walking, rather than horizontally as the wolf does. Coyote tracks can be distinguished from those of dogs by less rounded shape. Unlike dogs, the upper canines of coyotes extend past the mental foramina.
At the time of the European colonization of the Americas, coyotes were confined to open plains and arid regions of the western half of the continent. In early post-Columbian historical records, distinguishing between coyotes and wolves is difficult. One record from 1750 in Kaskaskia, written by a local priest, noted that the "wolves" encountered there were smaller and less daring than European wolves. Another account from the early 1800s in Edwards County mentioned wolves howling at night, though these were coyotes; this species was encountered several times during the Lewis and Clark Expedition, though it was well known to European traders on the upper Missouri. Lewis, writing on 5 May 1805, in northeastern Montana, described the coyote in these terms: The small woolf or burrowing dog of the prairies are the inhabitants invariably of the open plains.
