The Burra Burra Mine is a copper mine located in Ducktown, Tennessee, in the southeastern United States. Named for the famous mine in Australia, the Burra Burra Mine extracted over 15 million tons (14 million metric tons) of copper ore during its 60 years of operation between 1899 and 1959. The mine's remaining structures are listed on the National Register of Historic Places as part of the Burra Burra Mine Historic District. The site is also home to the Ducktown Basin Museum, and the museum and mine are a Tennessee state historic site operated in partnership with the Tennessee Historical Commission. The Burra Burra Mine was one of a number of mining operations in the Copper Basin from 1850 to 1987. While these operations produced substantial amounts of copper and other products, tree-harvesting and pollution from the mines and smelters left more than of the basin virtually devoid of life, though the area has begun to recover due to re-greening efforts. ==Geographical setting== The Burra Burra Mine is located near the center of the Copper (''or'' Ducktown) Basin, a broad valley in the southern Appalachian Mountains near the common borders of Tennessee, North Carolina, and Georgia. The basin—actually an area of low hills rather than a true basin— is surrounded on all sides by mountains, including Pack Mountain to the east, Stansbury Mountain to the north, Little Frog Mountain to the northwest, and Big Frog Mountain to the southwest, some more than high. A series of hills rise above the basin to the south. The Ocoee River flows through the southwestern section of the Copper Basin, entering from Georgia (where it is known as the Toccoa) and exiting via a scenic gorge between Big Frog Mountain and Little Frog Mountain to the west. The river's Copper Basin segment is located at just over upstream from the river's mouth along the Hiwassee River near Benton, Tennessee. The Tennessee Valley Authority's Ocoee Dam Number 3 has created a reservoir that extends into the Copper Basin segment. Ducktown, the location of the Burra Burra Mine, is in the center of the Copper Basin near the juncture of Tennessee State Route 68 and U.S. Route 64. Other communities located in or associated with the basin include Copperhill, near the Tennessee-Georgia border, Postelle in the northwest section of the basin, and Turtletown, just north of the basin. The Copper Basin is located almost entirely within Polk County, Tennessee, although parts of it extend into Fannin County, Georgia. The mine is at , at an altitude of 1798 feet (548 m) above mean sea level. 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「Burra Burra Mine (Tennessee)」の詳細全文を読む スポンサード リンク
