Yukon

"Yukon (also commonly called the Yukon) is the westernmost and smallest of Canada's three federal territories. Whitehorse is the territorial capital and Yukon's only city. ... 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." [Yukon. Wikipedia]
