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
The Tlingit are indigenous peoples of the Pacific Northwest Coast of North America. Their language is the Tlingit language, in which the name means "People of the Tides"; the Russian name Koloshi or the related German name Koulischen may be encountered referring to the people in older historical literature, such as Shelikhov's 1796 map of Russian America. The Tlingit have a matrilineal kinship system, with children considered born into the mother's clan, property and hereditary roles passing through the mother's line, their culture and society developed in the temperate rainforest of the southeast Alaska coast and the Alexander Archipelago. The Tlingit maintained a complex hunter-gatherer culture based on semi-sedentary management of fisheries. An inland group, known as the Inland Tlingit, inhabits the far northwestern part of the province of British Columbia and the southern Yukon Territory in Canada; the greatest territory occupied by the Tlingit extended from the Portland Canal along the present border between Alaska and British Columbia, north to the coast just southeast of the Copper River delta in Alaska.
The Tlingit occupied all of the Alexander Archipelago, except the southernmost end of Prince of Wales Island and its surroundings, where the Kaigani Haida moved just before the first encounters with European explorers. The Coastal Tlingit tribes controlled. Inland, the Tlingit occupied areas along the major rivers that pierce the Coast Mountains and Saint Elias Mountains and flow into the Pacific, including the Alsek, Chilkat and Stikine rivers. With regular travel up these rivers, the Tlingit developed extensive trade networks with Athabascan tribes of the interior, intermarried with them. From this regular travel and trade, a few large populations of Tlingit settled around Atlin and Tagish Lakes, whose headwaters flow from areas near the headwaters of the Taku River. Delineating the modern territory of the Tlingit is complicated because they are spread across the border between the United States and Canada, they lack designated reservations, other complex legal and political concerns make the situation confusing, there is a high level of mobility among the population.
They overlap in territory with various Athabascan peoples, such as the Tahltan and Tagish. In Canada, the modern communities of Atlin, British Columbia, Teslin and Carcross, Yukon have reserves and are the representative Interior Tlingit populations; the territory occupied by the modern Tlingit people in Alaska is not restricted to particular reservations, unlike most tribes in the lower contiguous 48 states. This is the result of the Alaska Native Claims Settlement Act, which established regional corporations throughout Alaska with complex portfolios of land ownership rather than bounded reservations administered by tribal governments; the corporation in the Tlingit region is Sealaska Corporation, which serves the Tlingit as well as the Haida and Tsimshian in Alaska. Tlingit people as a whole participate in the commercial economy of Alaska; as a consequence, they live in American nuclear family households with private ownership of housing and land. Many possess land allotments from Sealaska or from earlier distributions predating ANCSA.
Despite the legal and political complexities, the territory occupied by the Tlingit can be reasonably designated as their modern homeland. Tlingit people today consider the land from around Yakutat south through the Alaskan Panhandle, including the lakes in the Canadian interior, as being Lingít Aaní, the Land of the Tlingit; the extant Tlingit territory can be divided into four major sections, paralleling ecological and cultural divisions: The Southern Tlingit occupy the region south of Frederick Sound, live in the northernmost reaches of the Western Red cedar forest. Northern Tinglit live north of Frederick Sound to Cape Spencer, including Glacier Bay and the Lynn Canal; the Inland Tlingit live along large interior lakes and the drainage of the Taku River as well as in the southern Yukon, subsist in a manner similar to their Athabascan neighbors in the mixed spruce taiga. The Gulf Coast Tlingit live along a narrow strip of coastline backed by steep mountains and extensive glaciers, north of Cape Spencer, along the coast of the Gulf of Alaska to Controller Bay and Kayak Island.
Their territory can be battered by Pacific storms. The trade and cultural interactions between each of these Tlingit groups and their disparate neighbors, the differences in food harvest practices, dialectical differences in language contribute to these identifications; these academic classifications are supported by similar self-identification among the Tlingit. The Tlingit culture is multifaceted and complex, a characteristic of Northwest Pacific Coast people with access to exploited rich resources. In Tlingit culture a heavy emphasis is placed upon family and kinship, on a rich tradition of oratory. Wealth and economic power are important indicators of rank, but so is generosity and proper behavior, all signs of "good breeding" and ties to aristocracy. Art and spirituality are incorporated in nearly all areas of Tlingit culture, with even
The City and Borough of Juneau known as Juneau, is the capital city of Alaska. It is a unified municipality on Gastineau Channel in the Alaskan panhandle, it is the second largest city in the United States by area. Juneau has been the capital of Alaska since 1906, when the government of what was the District of Alaska was moved from Sitka as dictated by the U. S. Congress in 1900; the municipality unified on July 1, 1970, when the city of Juneau merged with the city of Douglas and the surrounding Greater Juneau Borough to form the current municipality, larger by area than both Rhode Island and Delaware. Downtown Juneau is nestled across the channel from Douglas Island; as of the 2010 census, the City and Borough had a population of 31,276. In 2014, the population estimate from the United States Census Bureau was 32,406, making it the second most populous city in Alaska after Anchorage. Fairbanks, however, is the state's second most populous metropolitan area, with 100,000 residents. Juneau's daily population can increase by 6,000 people from visiting cruise ships between the months of May and September.
The city is named after a gold prospector from Quebec, Joe Juneau, though the place was for a time called Rockwell and Harrisburg. The Tlingit name of the town is Dzántik'i Héeni, Auke Bay just north of Juneau proper is called Áak'w in Tlingit; the Taku River, just south of Juneau, was named after the cold t'aakh wind, which blows down from the mountains. Juneau is unusual among U. S. capitals in that there are no roads connecting the city to the rest of Alaska or to the rest of North America. The absence of a road network is due to the rugged terrain surrounding the city; this in turn makes Juneau a de facto island city in terms of transportation, since all goods coming in and out must go by plane or boat, in spite of the city being on the Alaskan mainland. Downtown Juneau sits at sea level, with tides averaging 16 feet, below steep mountains about 3,500 feet to 4,000 feet high. Atop these mountains is the Juneau Icefield, a large ice mass from which about 30 glaciers flow; the Mendenhall glacier has been retreating.
The Alaska State Capitol in downtown Juneau was built as the Federal and Territorial Building in 1931. Prior to statehood, it housed the federal courthouse and a post office, it housed the territorial legislature and many other territorial offices, including that of the governor. Today, Juneau remains the home of the state legislature and the offices of the governor and lieutenant governor; some other executive branch offices have moved elsewhere in the state. Recent discussion has been focused between relocating the seat of state government outside Juneau and building a new capitol building in Juneau. Long before European settlement in the Americas, the Gastineau Channel was a favorite fishing ground for the Auke and Taku tribes, who had inhabited the surrounding area for thousands of years; the A'akw Kwáan had a burying ground here. In the 21st century it is known as Indian Point, they annually harvested herring during the spawning season, celebrated this bounty. Since the late 20th century, the A'akw Kwáan, together with the Sealaska Heritage Institute, have resisted European-American development of Indian Point, including proposals by the National Park Service and the National Oceanic and Atmospheric Administration.
They consider it sacred territory, both because of the burying ground and the importance of the point in their traditions of gathering sustenance from the sea. They continue to gather clams, gumboots and sea urchins here, as well as tree bark for medicinal uses; the city and state supported Sealaska Heritage Institute in documenting the 78-acre site, in August 2016 it was listed on the National Register of Historic Places. "It is the first traditional cultural property in Southeast Alaska to be placed on the register."Descendants of these indigenous cultures include the Tlingit people. Native cultures have rich artistic traditions expressed in carving, orating and dancing. Juneau has become a major social center for the Tlingit and Tsimshian of Southeast Alaska. Although the Russians had a colony in the Alaska territory from 1784 to 1867, they did not settle in Juneau, they conducted extensive fur trading with Alaskan Natives of the Aleutian Islands and Kodiak. Some ships explored this area, but did not record it.
The first European to see the Juneau area is recorded as Joseph Whidbey, master of the Discovery during George Vancouver’s 1791–95 expedition. He and his party explored the region in July–August 1794. Early in August he viewed the length of Gastineau Channel from the south, noting a small island in mid-channel, he recorded seeing the channel again, this time from the west. He said. After the California gold rush, miners migrated up the Pacific Coast and explored the West, seeking other gold deposits. In 1880, Sitka mining engineer George Pilz offered a reward to any local chief in Alaska who could lead him to gold-bearing ore. Chief Kowee arrived with some ore, several prospectors were sent to in
The Great Depression was a severe worldwide economic depression that took place during the 1930s, beginning in the United States. The timing of the Great Depression varied across nations, it was the longest and most widespread depression of the 20th century. In the 21st century, the Great Depression is used as an example of how intensely the world's economy can decline; the Great Depression started in the United States after a major fall in stock prices that began around September 4, 1929, became worldwide news with the stock market crash of October 29, 1929. Between 1929 and 1932, worldwide gross domestic product fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession; some economies started to recover by the mid-1930s. However, in many countries the negative effects of the Great Depression lasted until the beginning of World War II; the Great Depression had devastating effects in countries both poor. Personal income, tax revenue and prices dropped, while international trade plunged by more than 50%.
Unemployment in the U. S. rose to 25% and in some countries rose as high as 33%. Cities around the world were hit hard those dependent on heavy industry. Construction was halted in many countries. Farming communities and rural areas suffered as crop prices fell by about 60%. Facing plummeting demand with few alternative sources of jobs, areas dependent on primary sector industries such as mining and logging suffered the most. Economic historians attribute the start of the Great Depression to the sudden devastating collapse of U. S. stock market prices on October 29, 1929, known as Black Tuesday. However, some dispute this conclusion and see the stock crash as a symptom, rather than a cause, of the Great Depression. After the Wall Street Crash of 1929 optimism persisted for some time. John D. Rockefeller said "These are days. In the 93 years of my life, depressions have gone. Prosperity has always returned and will again." The stock market turned upward in early 1930. This was still 30% below the peak of September 1929.
Together and business spent more in the first half of 1930 than in the corresponding period of the previous year. On the other hand, many of whom had suffered severe losses in the stock market the previous year, cut back their expenditures by 10%. In addition, beginning in the mid-1930s, a severe drought ravaged the agricultural heartland of the U. S. By mid-1930, interest rates had dropped to low levels, but expected deflation and the continuing reluctance of people to borrow meant that consumer spending and investment were depressed. By May 1930, automobile sales had declined to below the levels of 1928. Prices in general began to decline, although wages held steady in 1930. A deflationary spiral started in 1931. Farmers faced a worse outlook. At its peak, the Great Depression saw nearly 10% of all Great Plains farms change hands despite federal assistance; the decline in the U. S. economy was the factor. Frantic attempts to shore up the economies of individual nations through protectionist policies, such as the 1930 U.
S. Smoot–Hawley Tariff Act and retaliatory tariffs in other countries, exacerbated the collapse in global trade. By 1933, the economic decline had pushed world trade to one-third of its level just four years earlier. Change in economic indicators 1929–32 The two classical competing theories of the Great Depression are the Keynesian and the monetarist explanation. There are various heterodox theories that downplay or reject the explanations of the Keynesians and monetarists; the consensus among demand-driven theories is that a large-scale loss of confidence led to a sudden reduction in consumption and investment spending. Once panic and deflation set in, many people believed they could avoid further losses by keeping clear of the markets. Holding money became profitable as prices dropped lower and a given amount of money bought more goods, exacerbating the drop in demand. Monetarists believe that the Great Depression started as an ordinary recession, but the shrinking of the money supply exacerbated the economic situation, causing a recession to descend into the Great Depression.
Economists and economic historians are evenly split as to whether the traditional monetary explanation that monetary forces were the primary cause of the Great Depression is right, or the traditional Keynesian explanation that a fall in autonomous spending investment, is the primary explanation for the onset of the Great Depression. Today the controversy is of lesser importance since there is mainstream support for the debt deflation theory and the expectations hypothesis that building on the monetary explanation of Milton Friedman and Anna Schwartz add non-monetary explanations. There is consensus that the Federal Reserve System should have cut short the process of monetary deflation and banking collapse. If they had done this, the economic downturn would have been much shorter. British economist John Maynard Keynes argued in The General Theory of Employment and Money that lower aggregate expenditures in the economy contributed to a massive decline in income and to employment, well below the average.
In such a situation, the economy reached equilibrium at low levels of economic activity and high unemployment. Keynes' basic idea was simple
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, sleet, snow and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and "precipitates", thus and mist are not precipitation but suspensions, because the water vapor does not condense sufficiently to precipitate. Two processes acting together, can lead to air becoming saturated: cooling the air or adding water vapor to the air. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called "showers."Moisture, lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain occurs. A stationary front is present near the area of freezing rain and serves as the foci for forcing and rising air.
Provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. The cloud droplets will grow large enough to form raindrops and descend toward the Earth where they will freeze on contact with exposed objects. Where warm water bodies are present, for example due to water evaporation from lakes, lake-effect snowfall becomes a concern downwind of the warm lakes within the cold cyclonic flow around the backside of extratropical cyclones. Lake-effect snowfall can be locally heavy. Thundersnow is possible within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation. On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. Most precipitation is caused by convection; the movement of the monsoon trough, or intertropical convergence zone, brings rainy seasons to savannah climes.
Precipitation is a major component of the water cycle, is responsible for depositing the fresh water on the planet. 505,000 cubic kilometres of water falls as precipitation each year. Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres, but over land it is only 715 millimetres. Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on other celestial bodies, e.g. when it gets cold, Mars has precipitation which most takes the form of frost, rather than rain or snow. Precipitation is a major component of the water cycle, is responsible for depositing most of the fresh water on the planet. 505,000 km3 of water falls as precipitation each year, 398,000 km3 of it over the oceans. Given the Earth's surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective and orographic rainfall.
Convective processes involve strong vertical motions that can cause the overturning of the atmosphere in that location within an hour and cause heavy precipitation, while stratiform processes involve weaker upward motions and less intense precipitation. Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice. Mixtures of different types of precipitation, including types in different categories, can fall simultaneously. Liquid forms of precipitation include drizzle. Rain or drizzle that freezes on contact within a subfreezing air mass is called "freezing rain" or "freezing drizzle". Frozen forms of precipitation include snow, ice needles, ice pellets and graupel; the dew point is the temperature to which a parcel must be cooled in order to become saturated, condenses to water. Water vapor begins to condense on condensation nuclei such as dust and salt in order to form clouds. An elevated portion of a frontal zone forces broad areas of lift, which form clouds decks such as altostratus or cirrostratus.
Stratus is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass. It can form due to the lifting of advection fog during breezy conditions. There are four main mechanisms for cooling the air to its dew point: adiabatic cooling, conductive cooling, radiational cooling, evaporative cooling. Adiabatic cooling occurs when air expands; the air can rise due to convection, large-scale atmospheric motions, or a physical barrier such as a mountain. Conductive cooling occurs when the air comes into contact with a colder surface by being blown from one surface to another, for example from a liquid water surface to colder land. Radiational cooling occurs due to the emission of infrared radiation, either by the air or by the surface underneath. Evaporative cooling occurs when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature, or until it reaches saturation; the main ways water vapor is added to the air are: wind convergence into areas of upward motion, precipitation or virga falling from above, daytime heating evaporating water from the surface of oceans, water bodies or wet lan
Switzerland the Swiss Confederation, is a country situated in western and southern Europe. It consists of 26 cantons, the city of Bern is the seat of the federal authorities; the sovereign state is a federal republic bordered by Italy to the south, France to the west, Germany to the north, Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning a total area of 41,285 km2. While the Alps occupy the greater part of the territory, the Swiss population of 8.5 million people is concentrated on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva. The establishment of the Old Swiss Confederacy dates to the late medieval period, resulting from a series of military successes against Austria and Burgundy. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648; the country has a history of armed neutrality going back to the Reformation.
It pursues an active foreign policy and is involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to numerous international organisations, including the second largest UN office. On the European level, it is a founding member of the European Free Trade Association, but notably not part of the European Union, the European Economic Area or the Eurozone. However, it participates in the Schengen Area and the European Single Market through bilateral treaties. Spanning the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions: German, French and Romansh. Although the majority of the population are German-speaking, Swiss national identity is rooted in a common historical background, shared values such as federalism and direct democracy, Alpine symbolism. Due to its linguistic diversity, Switzerland is known by a variety of native names: Schweiz. On coins and stamps, the Latin name – shortened to "Helvetia" – is used instead of the four national languages.
Switzerland is one of the most developed countries in the world, with the highest nominal wealth per adult and the eighth-highest per capita gross domestic product according to the IMF. Switzerland ranks at or near the top globally in several metrics of national performance, including government transparency, civil liberties, quality of life, economic competitiveness and human development. Zürich and Basel have all three been ranked among the top ten cities in the world in terms of quality of life, with the first ranked second globally, according to Mercer in 2018; the English name Switzerland is a compound containing Switzer, an obsolete term for the Swiss, in use during the 16th to 19th centuries. The English adjective Swiss is a loan from French Suisse in use since the 16th century; the name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, one of the Waldstätten cantons which formed the nucleus of the Old Swiss Confederacy. The Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for "Confederates", used since the 14th century.
The data code for Switzerland, CH, is derived from Latin Confoederatio Helvetica. The toponym Schwyz itself was first attested in 972, as Old High German Suittes perhaps related to swedan ‘to burn’, referring to the area of forest, burned and cleared to build; the name was extended to the area dominated by the canton, after the Swabian War of 1499 came to be used for the entire Confederation. The Swiss German name of the country, Schwiiz, is homophonous to that of the canton and the settlement, but distinguished by the use of the definite article; the Latin name Confoederatio Helvetica was neologized and introduced after the formation of the federal state in 1848, harking back to the Napoleonic Helvetic Republic, appearing on coins from 1879, inscribed on the Federal Palace in 1902 and after 1948 used in the official seal.. Helvetica is derived from the Helvetii, a Gaulish tribe living on the Swiss plateau before the Roman era. Helvetia appears as a national personification of the Swiss confederacy in the 17th century with a 1672 play by Johann Caspar Weissenbach.
Switzerland has existed as a state in its present form since the adoption of the Swiss Federal Constitution in 1848. The precursors of Switzerland established a protective alliance at the end of the 13th century, forming a loose confederation of states which persisted for centuries; the oldest traces of hominid existence in Switzerland date back about 150,000 years. The oldest known farming settlements in Switzerland, which were found at Gächlingen, have been dated to around 5300 BC; the earliest known cultural tribes of the area were members of the Hallstatt and La Tène cultures, named after the archaeological site of La Tène on the north side of Lake Neuchâtel. La Tène culture developed and flourished during the late Iron Age from around 450 BC under some influence from the Gree
Yukon is the smallest and westernmost of Canada's three federal territories. It has the smallest population of any province or territory in Canada, with 35,874 people, although it has the largest city in any of the three territories. Whitehorse is Yukon's only city. Yukon was split from the Northwest Territories in 1898 and was named the Yukon Territory; the federal government's Yukon Act, which received royal assent on March 27, 2002, established Yukon as the territory's official name, though Yukon Territory is still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of YT. Though bilingual, the Yukon government recognizes First Nations languages. At 5,959 m, Yukon's Mount Logan, in Kluane National Park and Reserve, is the highest mountain in Canada and the second-highest on the North American continent. Most of Yukon has a subarctic climate, characterized by brief warm summers; the Arctic Ocean coast has a tundra climate. Notable rivers include the Yukon River, as well as the Pelly, Peel and Tatshenshini rivers.
The territory is named after the longest river in Yukon. The name itself is from a contraction of the words in the Gwich'in phrase chųų gąįį han, which means white water river and refers to "the pale colour" of glacial runoff in the Yukon River. Long before the arrival of Europeans and southern Yukon was populated by First Nations people, the area escaped glaciation. Sites of archeological significance in Yukon hold some of the earliest evidence of the presence of human habitation in North America; the sites safeguard the earliest First Nations of the Yukon. The volcanic eruption of Mount Churchill in 800 AD in what is now the U. S. state of Alaska blanketed southern Yukon with a layer of ash which can still be seen along the Klondike Highway, which forms part of the oral tradition of First Nations peoples in Yukon and further south in Canada. Coastal and inland First Nations had extensive trading networks. European incursions into the area began early in the 19th century with the fur trade, followed by missionaries.
By the 1870s and 1880s gold miners began to arrive. This drove a population increase that justified the establishment of a police force, just in time for the start of the Klondike Gold Rush in 1897; the increased population coming with the gold rush led to the separation of the Yukon district from the Northwest Territories and the formation of the separate Yukon Territory in 1898. The territory is the approximate shape of a right triangle, bordering the U. S. state of Alaska to the west and northwest for 1,210 km along longitude 141° W, the Northwest Territories to the east and British Columbia to the south. Its northern coast is on the Beaufort Sea, its ragged eastern boundary follows the divide between the Yukon Basin and the Mackenzie River drainage basin to the east in the Mackenzie mountains. Most of the territory is in the watershed of the Yukon River; the southern Yukon is dotted with a large number of large and narrow glacier-fed alpine lakes, most of which flow into the Yukon River system.
The larger lakes include Teslin Lake, Atlin Lake, Tagish Lake, Marsh Lake, Lake Laberge, Kusawa Lake and Kluane Lake. Bennett Lake on the Klondike Gold Rush trail is a lake flowing into Nares Lake, with the greater part of its area within Yukon. Canada's highest point, Mount Logan, is in the territory's southwest. Mount Logan and a large part of Yukon's southwest are in Kluane National Park and Reserve, a UNESCO World Heritage Site. Other national parks include Ivvavik National Vuntut National Park in the north. Other watersheds include the Mackenzie River, the Peel Watershed and the Alsek–Tatshenshini, a number of rivers flowing directly into the Beaufort Sea; the two main Yukon rivers flowing into the Mackenzie in the Northwest Territories are the Liard River in the southeast and the Peel River and its tributaries in the northeast. Notable widespread tree species within Yukon are white spruce. Many trees are stunted because of severe climate; the capital, Whitehorse, is the largest city, with about three-quarters of the population.
British Columbia Northwest Territories Alaska, United States While the average winter temperature in Yukon is mild by Canadian arctic standards, no other place in North America gets as cold as Yukon during extreme cold snaps. The temperature has dropped down to −60 °C three times, 1947, 1954, 1968; the most extreme cold snap occurred in February 1947 when the abandoned town of Snag dropped down to −63.0 °C. Unlike most of Canada where the most extreme heat waves occur in July and September, Yukon's extreme heat tends to occur in June and May. Yukon has recorded 36 °C three times; the first time was in June 1969 when Mayo recorded a temperature of 36.1 °C. 14 years this record was beaten when Forty Mile recorded 36 °C in May 1983. The old record was broken 21 years in June 2004 when the Mayo Road weather station, located just northwest of Whitehorse, recorded a temperature of 36.5 °C. The 2016 census reported a Yukon population of 35,874, an increase of 5.8% from 2011. With a land area of 474,712.64 km2, it had a population de
