A province and territory of Canada, Yukon is a region located at the country’s northwestern corner. 186,272 square miles make up the total area of Yukon, making it the 9th largest province in Canada. As the capital of Yukon, Whitehorse is the only city in the territory. Riverdale and downtown Whitehorse are located along the Yukon River, which flows from British Columbia to Alaska. The Yukon contains steep snow-capped mountains, active volcanoes (and dormant ones too), glaciers, snowmelt lakes, rivers rushing with cold water, coniferous forests, tundra, and the stark landscape of the Arctic. Its namesake, the Yukon River, spans most of the territory. In the southern Yukon, alpine lakes are abundant, primarily glacier-fed, long, and narrow. The Yukon volcanoes lie within the Pacific Ring of Fire, a ring of volcanoes circling the Pacific Ocean. A total of over 100 volcanoes have been active in Yukon during the Quaternary. In Yukon, there are eight provincial parks and three national parks.
