Whitehorse (total area population 27,889 as of 2013) is the capital and largest city of
Yukon, Canada and the largest city in
northern Canada. It was incorporated in 1950 and is located at kilometre 1426 on the
Alaska Highway in southern Yukon. Whitehorse's downtown and Riverdale areas occupy both shores of the
Yukon River, which originates in
British Columbia and meets the
Bering Sea in Alaska. The city was named after the
White Horse Rapids for their resemblance to the mane of a white horse, near
Miles Canyon, before the river was dammed. Because of the city's location in the Whitehorse valley, the climate is milder than other comparable northern communities such as
Yellowknife. At this latitude winter days are short and summer days have 20 hours of daylight. Whitehorse, as reported by
Guinness World Records, is the city with the least air pollution in the world.
