Geologic map and coal resources of the White Butte NE quadrangle, Stark and Hettinger Counties, North Dakota
Kenneth S. Soward
1975, Coal Map 72
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,...

Hydrology of sand-and-gravel aquifer in central and southern Escambia County, Florida
Henry Trapp Jr.
1975, Open-File Report 74-218
The sand-and-gravel aquifer is the only fresh-water aquifer in the Pensacola area. Problems related to development of the aquifer include maximum safe yield, local contamination, local salt-water intrusion, corrosiveness of the water, areas of high iron concentration, and increasing nitrate concentration. The city of Pensacola is seeking hydrologic information, including...
A summary of relative ages of lunar nearside and farside plains
Joseph M. Boyce, Arthur L. Dial, Laurence A. Soderblom
1975, Open-File Report 75-141
This report contains a summary of the moon-wide distribution of relative ages of lunar plains units determined with Apollo and Lunar Orbiter photographs. Relative ages are expressed as the largest diameter of craters (DL, meters) in a mappable unit that are eroded to a slope of 1° by the net...

Reconnaissance study of sediment transport by selected streams in the Yakima Indian Reservation, Washington, 1974 water year
Philip Richard Boucher
1975, Open-File Report 75-67
This was a reconnaissance study for information on suspended-sediment concentrations and basin yields at 21 sites on selected streams in the Yakima Indian Reservation in Washington, and two sites on nearby streams. Suspended-sediment yields were generally low relative to those indicated by data for other streams on southeastern Washington, the...
A water-quality assessment of the Jordan Creek watershed, Warren County, Indiana
Mark A. Ayers
1975, Open-File Report 75-323
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...
Chemical analysis of the waters of the Yellowstone National Park, Wyoming from 1965 to 1973
J. M. Thompson, T. S. Presser, R.B. Barnes, D.B. Bird
1975, Open-File Report 75-25
Analyses of Yellowstone Park thermal waters have been reported by many investigators extending back almost one hundred years. The first detailed analyses were reported by Gooch and Whitfield (1888). Allen and Day (1935) were second. White, Brannock, and Murata (1956) and Morey, Fournier, Hemley, and Rowe (1961) reported field analyses...
Prediction of maximum earthquake intensities for the San Francisco Bay region
Roger D. Borcherdt, James F. Gibbs
1975, Open-File Report 75-180
The intensity data for the California earthquake of April 18, 1906, are strongly dependent on distance from the zone of surface faulting and the geological character of the ground. Considering only those sites (approximately one square city block in size) for which there is good evidence for the degree of...

A review of recently active faults in Taiwan
Manuel G. Bonilla
1975, Open-File Report 75-41
Six faults associated with five large earthquakes produced surface displacements ranging from 1 to 3 m in the period 1906 through 1951. Four of the ruptures occurred in the western coastal plain and foothills, and two occurred in the Longitudinal Valley of eastern Taiwan. Maps are included showing the locations...

A water-quality assessment of the Rock Creek (Cass) watershed, Cass and Carroll counties, Indiana
Mark A. Ayers
1975, Open-File Report 75-324
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...
