The Greenwood gold mine operated in Prince William County, Virginia, United States, near the town of Independent Hill for a few years before closing in 1885.〔(NPS History - Greenwood Gold Mine ) Retrieved February 15, 2010〕 It was one of two known gold mines in Prince William County, the other being the Crawford placer prospect on Neabsco Creek, near I-95, though small amounts of gold were occasionally found at the Cabin Branch Pyrite Mine in nearby Dumfries. The Greenwood site was situated at the head of the North branch of Quantico Creek on what is now part of Prince William Forest Park near the intersection of Aden and Bristow Roads in the far northwestern area of the park. The site is situated along the Virginia Gold-Pyrite belt, which runs from northeast to southwest primarily through the counties of Fairfax, Prince William, Stafford, Spotsylvania, Buckingham, Culpeper, Cumberland, Fauquier, Floyd, Fluvanna, Goochland, Halifax, Louisa, Orange, and Patrick. Mining operations consisted of at least one shaft, a stamp mill, and some form of mercury amalgamation recovery. The mine was a significant source of mercury pollution on Quantico Creek, and has since undergone complete reclamation including the sealing of mine shaft(s), soil removal and/or decontamination, and removal of obvious tailings. As of 2010, the only visible evidence of the mine are a few depressions in the soil. No structures or equipment remain. The National Park Service charges a $5 fee for entry into the park and does not allow collecting of rocks or minerals. ==See also== *Virginia gold mining 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「Greenwood Gold Mine」の詳細全文を読む スポンサード リンク
