1979, Open-File Report 79-988
Data obtained during a hydrologic reconnaissance in 1975-77 in the Wasatch Plateau-Book Cliffs coal area of Utah were correlated with existing long-term data. Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches...
An appraisal of pumping effects on the Edgeley Aquifer, La Moure County, North Dakota, as determined by a digital model
M. R. Burkart
1979, Open-File Report 79-748
A finite-difference digital model simulated hydrologic conditions in the Edgeley aquifer, which is an unconfined glacial-drift aquifer. The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water...

1979, Open-File Report 79-670
On 28 February 1979 an earthquake with surface wave magnitude (Ms) of 7.7 (W. Person, personal communication, 1979) occurred beneath the Chugach and St. Elias mountains of southern Alaska (fig. 1). This is a region of complex tectonics resulting from northwestward convergence between the Pacific and North American plates. To...

Quality of water in Bayou Casotte and Bayou Chico, Jackson County, Mississippi
Gene A. Bednar
1979, Open-File Report 79-1059
A short-term water-quality study on Bayou Casotte and Bayou Chico on the Mississippi Gulf Coast was conducted on July 25-27, 1978. The results of the study indicated that the chemical and physical properties and range of concentrations of several dissolved constituents in both estuaries varied during a tide cycle primarily...
Water resources of the Santa Rosa Indian Reservation and vicinity, Riverside County, California
Anthony Buono, W. R. Moyle, Patricia Dana
1979, Open-File Report 79-1172
Additional water for irrigation is needed by the Santa Rosa Indian Reservation, Riverside County, California. Water in the area is derived from precipitation, which averages 12 inches annually, on three subbasins nearly surrounding the 17-square-mile reservation. No ground water flows in from outside the area. A supply well that taps...

Trace metals in surface sediments of the Mid-Atlantic Continental Shelf
Michael H. Bothner
1979, Open-File Report 79-843
The concentrations of 9 trace metals (Fe, Pb,Zn, Ba, Cu, Ni, V, Cr, and Cd) in surficial Continental Shelf sediments are low compared to the concentrations reported for average crustal rocks. No evidence for the accumulation of anthropogenic trace metals was found at the 51 locations sampled in this study....

Mineralogy as a guide for exploration in the Montezuma District, central Colorado
Theodore Botinelly
1979, Open-File Report 79-1177
The Montezuma district of central Colorado is a small base metal-silver mining district containing vein deposits associated with a Tertairy porphyry stock. The distribution of tetrahedrite having large unit-cell edges correlates in part with the distribution of more productive mines and suggests areas favorable for further production. The abundance of...
