White Horse Rapids

The Whitehorse rapids were rapids on the Yukon River in Canada's Yukon Territory, named for their supposed resemblance to the mane of a charging white horse. The rapids formed where the Yukon River flows across and cuts down through lava flows of the Miles Canyon basalt. These rapids presented a major navigational obstacle on the Yukon River during the Klondike Gold Rush, and lent their name to the nearby town of Whitehorse.
