Watson Lake is a town at historical mile 635 on the Alaska Highway in the southeastern Yukon close to the British Columbia border. Population in December 2004 was 1,547 (Yukon Bureau of Statistics).

Watson Lake is near the Liard River, at the junction of the Robert Campbell Highway and the Alaska Highway. The Cassiar Highway's northern end is 22 kilometres (14 miles) west of Watson Lake. The town is also served by the Watson Lake Airport; the airport was formerly served by Canadian Pacific Airlines and other local and regional airlines, but now only provides corporate and charter services.

Watson Lake is the main centre of the small forestry industry in the Yukon and has been a service centre for the mining industry, especially for the Cassiar asbestos mine in northern British Columbia and the Cantung tungsten mine on the Yukon-Northwest Territories border in the Mackenzie Mountains.

Tourist attractions in Watson Lake include the Northern Lights Centre and the much-imitated original Signpost Forest. The Signpost Forest was started in 1942 by a homesick U.S. Army G.I. working on the Alaska Highway, who put up a sign with the name of his home town and the distance. Others followed suit and the tradition continues to this day. Today there are more than 76.000 (aug 2010) signs of various types depicting locations across the world. The Signpost Forest is one of four roadside attractions featured on the first series of the Canadian Roadside Attractions Series issued by ‎Canada Post on July 6, 2009.

Yukon/ˈjuːkɒn/ is the westernmost and smallest of Canada's three federal territories.

The territory was created from the rump of the Hudson's Bay Company's North-Western Territory in 1898 as "the Yukon". Receiving royal assent on March 27, 2002, the federal government moderized 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 Mount McKinley in the U.S. state of Alaska). The territory's climate is Arctic and subarctic, resulting in long cold winters, short summers, and little precipitation.

It was named after the Yukon River. The word Yukon means "Great River" in Gwich’in.

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. Whitehorse is the territorial capital.
