The Klondike ( //) is a region of the Yukon territory in northwest Canada, east of the Alaskan border. It lies around the Klondike River, a small river that enters the Yukon River from the east at Dawson City.
The area is merely an informal geographic region, and has no function to the territory as any kind of administrative region.
The name "Klondike" evolved from the Hän word Tr'ondëk, which means " hammerstone water". Early gold seekers found it difficult to pronounce the First Nations word, so "Klondike" was the result of this poor pronunciation.
The climate is warm in the short summer, and very cold during the long winter. By late October, ice will have formed over the rivers. For the majority of the year, the ground is frozen to a depth of 1 to 3 metres (3 to 10 ft).
