 The territory only obtained a recognizable local government in 1895 when it became a separate district of the Northwest Territories.
 In 1898, Yukon was made a separate territory with its own commissioner and appointed Territorial Council.

The lost Wheelbarrow Mine is claimed to have been located about 10 mi from Potlatch in Latah County, Idaho.
 The reported location is 3,871 feet above sea level, at coordinates 46.9975° N, 116.7833° W.
 The mine, believed to have been dug prior to 1890, was said to have produced $20,000 in gold, before a falling-out between its operators led to its abandonment.
