Subgraphic pattern of calaverite, sylvanite and hessite, Gold King mine. La Plata County, Colorado. 1936.

Photomicrograph of polished sections of ore: subgraphic pattern of calaverite and sylvanite in hessite, Calaverite, sylvanite and hessite. These textures may indicate replacement of hessite by gold tellurides, but owing to its rarity, such replacement is not believed to be important in La Plata ores. Reflected light 250 x. Gold King mine. Photo by F.W. Galbraith. La Plata County, Colorado. Circa 1936. Plate 10-C, in U.S.Geological Survey Professional paper 219. 1949.

Aqueous and solid phase geochemistry of water and mineral precipitates from draining adits in California and Colorado

This dataset is a compilation of samples collected from draining mine adits, including water and mineral precipitates, from several mines in California and Colorado. The Golinsky, Copper Bluff, and Afterthought Mines (located in northern California) and the Gold King mine (located in southern Colorado) have historically operated to recover metals including copper, lead, zinc, gold, silver and other resources (Albers and Robertson, 1961; USGS, 2005; USEPA, 2015). Data reported include field parameters, water chemistry, solid phase mineralogy and solid phase chemistry. Water samples collected from the four mine sites in 2019 were analyzed for unfiltered and filtered (0.1-0.45 micrometer) major and trace elements and...

Digital Elevation Model of Glen Canyon Prior to the Flooding of Lake Powell from Historic Topographic Surveys, Utah and Arizona

Development of a high-resolution digital elevation model (DEM) of the pre-Glen Canyon Dam topography in Glen Canyon National Recreation Area, Utah and Arizona was initiated to assist the U.S. Geological Survey (USGS) in its Lake Powell coring program in the fall of 2018 (https://www.usgs.gov/centers/ut-water/science/lake-powell-coring). Topographic surveys of Glen Canyon were commissioned by the Bureau of Reclamation during the planning stages for Lake Powell as part of the Colorado River Storage Project (S. 500, 1956). The Colorado River arm was surveyed by Alster and Associates, Inc. in 1958 and 1959 at a contour interval of 10-feet from the river surface at the future dam site through where the 3,750-foot contour...

Initial core data of 2018 sediment cores from Lake Powell, Utah

The Lake Powell Coring Project was a USGS research effort, in cooperation with the Utah Department of Environmental Quality, U.S. Bureau of Reclamation, and U.S. National Park Service. In the fall of 2018, hydraulic piston cores targeted sediment that had been deposited in Lake Powell. This large reservoir on the Colorado River in Utah and Arizona was created after the completion of Glen Canyon Dam in 1963. Retrieval and analysis of cores was undertaken in response to the Gold King mine release from the Bonita Peak Mining District in Colorado on August 5, 2015. This event resulted in the containment loss of three-million gallons of mine-impacted waters which flowed from the Animas River into the San Juan River,...

Part 2 – Core and core section information from the 2018 coring project in Lake Powell, Utah

This section of the data release includes core and core section information in the format of a comma-separated value (CSV) file (2018LakePowellCoring_CoreSectionInfo.csv). It is Part 2 (of four) in this data release and provides detailed core information. Complete recovery of a core resulted in approximately 3 m of sediment, which was sectioned into lengths not exceeding 1.5 m shipboard. Thus, all cores with >50% recovery contain multiple sections. This CSV includes drillhole, core, and core section identifiers, section lengths, section tops and bottoms, scaled section tops and bottoms, filenames for corresponding core images, and drilling comments. Drillhole information, such as location and total recovery, are...
