Yukon: is the westernmost and smallest of Canada's three federal territories. Whitehorse is the territorial capital. The territory was split from the Hudson's Bay Company's North-Western Territory in 1898. Receiving royal assent on March 27, 2002, the federal government modernized the Yukon Act to confirm "Yukon", rather than "Yukon Territory", as the current usage standard. Though officially bilingual (English and French), the Yukon Government also recognizes First Nations languages. At 5,959 m (19,551 ft), Yukon's Mount Logan, in Kluane National Park and Reserve, is the highest mountain in Canada and the second-highest of North America (after Denali in the U.S. state of Alaska). The territory's climate is Arctic in the north (north of Old Crow), subarctic in the central region, between north of Whitehorse and Old Crow, and has a humid continental climate in the far south, south of Whitehorse and in areas close to the British Columbia border. The territory is the approximate shape of a right triangle, bordering the U.S. state of Alaska to the west for 1,210 km (752 mi) mostly 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 mostly 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 its namesake, the Yukon River. The southern Yukon is dotted with a large number of large, long 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 the Yukon. Canada's highest point, Mount Logan (5,959 m/19,551 ft), is in the territory's southwest. Mount Logan and a large part of the Yukon's southwest are in Kluane National Park and Reserve, a UNESCO World Heritage Site. Other national parks include Ivvavik National Park and Vuntut National Park in the north. Other watersheds include the Mackenzie River, the Peel watershed and the Alsek�Tatshenshini, and 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 the Yukon are the Black Spruce and White Spruce. Many trees are stunted because of the short growing season and severe climate. The capital, Whitehorse, is also the largest city, with about two-thirds of the population; the second largest is Dawson City (pop. 1,327), which was the capital until 1952.
