Robert G. Hobbs
1978, Open-File Report 78-401
The Geological Survey conducted a seven-hole core-drilling program in the Recluse Geologic Analysis Area, northern Campbell County, Wyoming, in 1975. The purpose was to acquire rock and coal samples to further evaluate the surface-minable coals of this area. In 1976 the Bureau of Land Management defined a portion of this...
Preliminary geologic report on the Harris Lake area, northeastern Minnesota
M. P. Foose, Roger W. Cooper
1978, Open-File Report 78-385
Intense faulting and fracturing in the Harris Lake area) northeastern Minnesota are documented by detailed field studies. Faults are identified chiefly by the disruption of mappable layers within sequences of plagioclase and plagioclase-olivine cumulates. Most layers grade from olivine-rich bottoms to plagioclase-rich tops and were probably deposited by density currents....

1978, Open-File Report 78-735
The Merced River originates on the western slope of the Sierra Nevada and flows through Yosemite National Park. The river drains 1,276 square miles before joining the San Joaquin River near Stevinson, Calif. Data were collected to permit descriptions of the river's quality during a hydrologic cycle, the natural and...

Virgin Islands sand resource study
Charles Ward Holmes
1978, Open-File Report 78-919
The depletion of sand resources in the Virgin Islands has necessitated the search for more economical supplies. The dynamic processes which produce sand in the nearshore environments are very slow, and removal of this material would cause a depletion of beaches upon which the island economy is predicated. A search...
Sonobuoy refraction data near Kodiak, Alaska

1978, Open-File Report 78-368
A total of 88 unreversed sonobuoy refraction lines were shot over the continental shelf and slope near Kodiak, Alaska, in 1976 and 1977. Useful results were obtained from 59 of these attempts. The field measurements were carried out aboard the USGS research vessel SAMUEL P. LEE. The refraction lines were...

Geologic setting of the lead and zinc deposits, Drenchwater Creek area, Howard Pass Quadrangle, Western Brooks Range, Alaska
Warren J. Nokleberg, Gary R. Winkler
1978, Open-File Report 78-70-C
Significant concentrations of galena, sphalerite, and minor barite are present in the Drenchwater Creek area, Howard Pass quadrangle, western Brooks Range, Alaska. Detailed geologic mapping indicates that galena, sphalerite and pyrite occur sporadically in a zone at least 1,830 m. long and 6-30 m. wide. The sulfides occur in tuff,...
Documentation of potential for surface faulting related to ground-water withdrawal in Las Vegas Valley, Nevada
Thomas L. Holzer
1978, Open-File Report 78-79
Leveling data collected in Las Vegas Valley are compatible with the interpretation that ongoing land-surface displacements related to ground-water withdrawal may be precursory to fault offset of the land surface. Zones of potential faulting intersect regions of intense urban development. The degree of risk and the potential economic consequences from...

1978, Open-File Report 78-664
Low-flow characteristics of Wisconsin streams in basins considered for work under Public Law 566 are presented in this report. The low-flow characteristics presented are the annual minimum 1-day mean flow below which the flow will fall on the average of once in 2 years (Q7,2) and the annual minimum 7-day...
Geophysical data from the 1975 cruise of the NOAA ship Surveyor in northern Gulf of Alaska
Bruce Molnia, Paul R. Carlson, Lisa H. Wright
1978, Open-File Report 78-209
In April and Flay 1975, a U.S. Geological Survey marine geology field party under the leadership of Bruce F. Molnia and Paul R. Carlson collected geophysical data from the N.O.A.A. ship Surveyor. The cruise, which consisted of 3 legs, studied the area between Cross Sound and Seward (Figure 1). Maps...
Impact of coastal processes on resource development with an example from Icy Bay, Alaska
Bruce F. Molnia
1978, Open-File Report 79-1693
The coastline of Alaska is dynamic and continually readjusting to changes in the many processes that operate in the coastal zone. Because of this dynamic nature, special consideration must be made in planning for development, and. caution must be exercised in site selection for facilities to be emplaced in the...
