Yellowknife is also the only city in the Northwest Territories. A small, culturally diverse city in the far north of Canada, Yellowknife combines all the urban amenities with memories of the old gold prospecting days. Gold and government administration were the mainstays of Yellowknife's economy until the late 1990s when the fall of gold prices led to the closure of the two main gold companies and the creation of the new territory of Nunavut meant the transfer out of a third of government employees. The discovery of diamonds in the Northwest Territories in 1991 came to the rescue, and diamond mining, cutting, polishing and selling became major activities for Yellowknife residents. While winters in Yellowknife are cold and dark, long summer days with plenty of sunshine make Yellowknife a magnet for outdoor adventurers and nature lovers.
