Ground-water reconnaissance in the Fresno Northeast area, Fresno County, California
R. W. Page
1975, Open-File Report 75-315
The Fresno northeast area includes about 133 square miles (344 square kilometres) in the central part of California. Four physiographic units occur in the area, the largest of which is the compound alluvial fan of the intermittent streams north of the Kings River.Geologic units consist of consolidated rocks and unconsolidated...

Preliminary report on the economic potential of the Chattanooga Shale in Tennessee, data as of 1962
Andrew Brown, Irving May
1975, Open-File Report 75-135
The Geological Survey?s investigations of the Chattanooga shale in Tennessee and adjacent states on behalf of the U.S. Atomic Energy Commission consisted mostly of geologic studies and routine analyses of samples for uranium. In the course of the studies, however, other investigations were made, primarily to find answers to specific...

Numerical model of the salt-wedge reach of the Duwamish River estuary, King County, Washington
Edmund A. Prych, W.L. Haushild, J.D. Stoner
1975, Open-File Report 75-13
A numerical model of a salt-wedge estuary developed by Fischer has been expanded and used to calculate the distributions of salinity, temperature, chlorophyll a concentrations, biochemical oxygen demand, and dissolved-oxygen concentrations in the Duwamish River estuary, King County, Wash. With this model, which was calibrated and verified with observed data,...
Preliminary evidence for Holocene movement along the Belair fault zone near Augusta, Georgia
David C. Prowell, Bruce J. O’Connor, Meyer Rubin
1975, Open-File Report 75-680
The Belair fault zone has the youngest displacement recognized to date in the southeastern United States and is the only fault zone dated as having moved in Holocene time. A trench cut across one of the faults in the zone shows lenses of organic material cut by and dragged into...
Computer program to simulate the salt balance between the north and south parts of Great Salt Lake, Utah
K.M. Waddell, E.L. Bolke
1975, Open-File Report 75-131
This report presents a computer simulation program that was used by Waddell and Bolke (1973) to predict the salt balance between the north and south parts of Great Salt Lake, Utah, for either existing or modified culvert openings (fig. 1). The development of the program, its accuracy and limitations, are...

Self-calibrating seismic amplifier and telemetry system
John R. Van Schaack
1975, Open-File Report 75-64
A frequency modulated, constant bandwidth, telemetry system has been designed to transmit simultaneously up to 8 channels of seismograph data from remote locations to a central recording site via radio or voice-grade telephone circuit. By utilizing state-of-the-art integrated circuits, the size of the remote unit has been considerably reduced over...
Maps showing maximum earthquake intensity predicted in the southern San Francisco Bay region, California, for large earthquakes on the San Andreas and Hayward Faults
Roger D. Borcherdt, James F. Gibbs, Kenneth R. Lajoie
1975, Miscellaneous Field Studies Map 709
This map shows maximum earthquake intensity predicted at specific sites using the empirical relations derived from the reliable 1906 intensity data (figs. 3 and 4; see text). The numbers 4-0 correspond to letters A-E, respectively, of the San Francisco intensity scale. The predicted intensity value shown for each site is...
