Geochemical data for environmental studies of mineral deposits at Nabesna, Kennecott, Orange Hill, Bond Creek, Bremner, and Gold Hill, Wrangell-St. Elias National Park and Preserve, Alaska
Environmental geochemical investigations were carried out between 1994 and 1997 in Wrangell-St. Elias National Park and Preserve (WRST), Alaska. Mineralized areas studied include the historic Nabesna gold mine/mill and surrounding areas; the historic Kennecott copper mill area and nearby Bonanza, Erie, Glacier, and Jumbo mines; the historic mill and gold mines in the Bremner district; the active gold placer mines at Gold Hill; and the unmined copper-molybdenum deposits at Orange Hill and Bond Creek. The purpose of the study was to determine the extent of possible environmental hazards associated with these mineralized areas and to establish background and baseline levels for selected elements. Thus, concentrations of a large suite of trace elements were determined to assess metal loadings in the various sample media collected. This report presents the methodology, analytical results, and sample descriptions for water, leachate, sediment, heavy-mineral concentrate, rock, and vegetation (willow) samples collected during these geochemical investigations. An interpretive U.S. Geological Survey Professional Paper incorporating these geochemical data will follow.
