<P> The volcanic eruption of Mount Churchill in approximately 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, and which forms part of the oral tradition of First Nations peoples in Yukon and further south in Canada . </P> <P> Coastal and inland First Nations had extensive trading networks . European incursions into the area only 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 . </P> <P> 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 (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 . </P> <P> 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 Yukon . </P>
