The name reflected the distance of the river mouth from Fort Reliance, a former Hudson's Bay Company post upstream along the Yukon River.〔 Miners eventually extracted more than a half-million ounces of gold from the Fortymile watershed. After the gold discovery, two Alaska Commercial Company traders, Jack McQuesten and Arthur Harper, built a post at the mouth of the river. Between 1968 and 1978, Cassiar Mining extracted about a million metric tons of asbestos from three open pits along Clinton Creek, a tributary of lower Fortymile River in the Yukon. After abandoning the site, the company went bankrupt in 1992, and the territorial and Canadian governments and others removed or buried mine wastes, stabilized the creek banks, and worked to partly restore the land.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fortymile River」の詳細全文を読む スポンサード リンク
