Digital models of a glacial outwash aquifer in the Pearl-Sallie Lakes area, west-central Minnesota
S. P. Larson, Mark S. McBride, R. J. Wolf
1975, Water-Resources Investigations Report 75-40
-p^e need for study of lake-ground-water interchange has been accentuated by eutrophication of lakes in the Pearl-Sallie Lakes area of west-central Minnesota. The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at...
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...
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...
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...
Summary of floods in the United States during 1969
J.K. Reid
1975, Water Supply Paper 2030
The most outstanding floods in the United States during 1969 are described in chronological order. The areas most seriously affected by flooding were: Central and southern California (January and February); the upper Midwestern States of North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, and Illinois (April); north-central Ohio (July); Mississippi, Alabama,...
U, Th, and K analyses of selected plutonic rocks from west-central Alaska
Thomas P. Miller, Carl M. Bunker
1975, Open-File Report 75-216
Numerous samples of plutonic rocks collected during reconnaissance mapping in western Alaska have been analyzed for K, U, and Th. The U and Th content of the plutonic rocks from the southeastern Seward Peninsula have been discussed in a separate report (Miller and Bunker, 1975); because of the current interest...
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...
Map showing paleocurrent and clast-size data from the Devonian-Mississippian Endicott Group, northern Alaska
T.J. Donovan, I.L. Tailleur
1975, Miscellaneous Field Studies Map 692
The Devonian-Mississippian Endicott Group (Tailleur and others, 1967) is an important geologic unit in the Brooks Range of northern Alaska. It reflects a major tectonic event in the middle and late Paleozoic history of the North American Cordillera. Tailleur and Brosge (1970) interpreted the Endicott as a clastic wedge derived...
Aluminum resources of Brazil
Max Gregg White
1975, Open-File Report 75-30
Large deposits of bauxite, the principal ore of aluminum, occur at several places in Brazil. The largest deposits now undergoing extensive exploration and development are in the eastern Amazon Basin. Most of these deposits are in the State of Para, but some are in Amazonas and Maranhao.Discovery of large-scale resources...
Water resources data for Mississippi, water year 1974
Water Resources Division, U.S. Geological Survey
1975, Water Data Report MS-74-1
Water resources data for the 1974 water year for Mississippi including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, special information on the flood in south-central Mississippi in April, and records of water-quality data on the chemical and physical characteristics of surface water, are...
Analytical data for geologic units in Missouri and parts of Kansas, Oklahoma and Arkansas
Josephine G. Boerngen, George Van Trump, Richard J. Ebens
1975, Open-File Report 75-137
This report lists the geochemical data collected during the course of a reconnaissance study of compositional variation in the bedrock and surficial gelogic untis exposed in Missouri and adjoining parts of Kansas, Oklahoma, and Arkansas.  The primar object of the study was to assess scale-related components of geochemical variance with...
