The White Butte NE, NW, East, and West quadrangles, were mapped as part of the U.S. Geological Survey program of classifying Federal lands and to make a systemic study and evaluation of the coal resources. Economic resources in the White Butte quadrangles consist of coal, oil and gas, sodium chloride, limestone,...

LANDSAT-I (ERTS-I) multispectral reflectance data were used to enhance the detection of alteration around uranium deposits near Cameron, Ariz. The technique involved stretching and ratioing computer-enhanced data from which electronic noise and atmospheric haze had been removed. Using present techniques, the work proves that LANDSAT-I data are useful in detecting...

For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...

A water-quality assessment of the Rock Creek (Cass) watershed was made June 12 and 13, 1974. Nutrients were resampled November 7, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents. Samples collected June 13 contained between 7.4 and 14 milligrams per...

The Puget Sound Basin has a history of frequent seismic activity, including two recent damaging events. The greatest extent of urban development and the most densely populated area generally correspond to the area where the greatest energy release has been experienced. For this study two earthquakes have been simulated, each...

A water-quality assessment of the Jordan Creek watershed was made September 24 and 25, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents and specific conductance values. Streamwaters contained less than 0.26 milligram per litre dissolved nitrate (as N), 0.03 milligram...

The southwestern part of Seminole County--in east-central Florida-is characterized by sinkholes formed by the subsidence of surficial deposits into solution cavities in the underlying limestone deposits. The area includes three sinkhole basins created by such subsidence: Cranes Roost, Palm Springs, and Grace Lake.Cranes Roost basin (drainage area, 5.02 square miles)...
