For the river, see Yukon River
Yukon is Canada's westernmost territory and the second least populous after Nunavut. Dominated by an arctic climate and tundra environment, its economy consists almost entirely of mineral resource extraction or other raw materials. It has a population of 30,000; the capital and largest city is Whitehorse. Yukon experienced a rush of settlement in the late 1800s with the Klondike Gold Rush, but only few struck gold and the rush fizzled out. The Mackenzie River flows through the territory, which is the smallest territory in Canada. Mount Logan, Canada's highest point and the second highest mountain in North America (after Denali) at 19,500 feet high, is on the United States-Canada border in Yukon.
