Tactical approach for determining impact of energy development on wildlife in Wyoming: special report number 1
Kent D. Keenlyne
1977, FWS/OBS 77/42
The U.S. Fish and Wildlife Service, within the Department of Interior, is responsible for providing national leadership in the management and protection of the nation's fish and wildlife resources, their habitat, and environment. Specifically, the Office of Biological Services obtains and assimilates biological and environmental data and identifies additional informational...
Geologic time: The age of the Earth
William L. Newman
1977, Report
The Earth is very old 4 1/2 billion years or more according to recent estimates. This vast span of time, called geologic time by earth scientists and believed by some to reach back to the birth of the Solar System, is difficult if not impossible to comprehend in the familiar...
Natural hazards on the island of Hawaii
D. W. Peterson, D. R. Mullineaux
1977, Report
The island of Hawaii and the other islands of the Hawaiian chain are products of volcanic eruptions. Lava flows from hundreds of thousands of eruptions through countless centuries have built the Hawaiian Islands. Some volcanoes on the island of Hawaii have been very active during historic time, and similar activity...
Geologic setting of the John Day Country, Grant County, Oregon
Thomas P. Thayer
1977, Report
One of the Pacific Northwest's most notable outdoor recreation areas, the "John Day Country" in northeastern Oregon, is named after a native Virginian who was a member of the Astor expedition to the mouth of the Columbia River in 1812. There is little factual information about John Day except that...
Drilling for scientific purposes
Eugene Merle Shoemaker, U.S. National Research Council, U.S. Geodynamics Committee
1977, Book chapter, Geodynamics Project: U.S. progress report, 1977
No abstract available....
Geochemical and petrological studies of a uraniferous granite from the Granite Mountains, Wyoming
John S. Stuckless, C. M. Bunker, C. A. Bush, W. P. Doering, J. H. Scott
1977, Journal of Research of the U.S. Geological Survey (5) 61-81
Granite rocks from the Granite Mountains, Wyo. have been proposed as the source of uranium deposits in the Crooks Gap, Gas Hills and Shirley Basin uranium districts, Wyoming. We have divided these granitic rocks into four units: (1) a biotitic phase which forms the dominant unit at the western end...
Geochemistry of amphibolites from the central Beartooth Mountains, Montana-Wyoming
Theodore J. Armbrustmacher, Frank S. Simons
1977, Journal of Research of the U.S. Geological Survey (5) 53-60
Trends of variation of major- and minor-element contents in amphibolites from the central Beartooth Mountains strongly suggest that these rocks of andesitic composition are derived from a tholeiitic, mafic igneous parent and not from a sedimentary parent. Discriminant functions based on minor-element content also indicate igneous parentage, whereas functions based...
Access routes to the United States Geological Survey's National Center, Reston, Virginia
Water Resources Division, U.S. Geological Survey
1977, Report
The National Center: The U.S. Geological Survey, established in 1879 as a bureau in the Department of the Interior, is one of the Federal Government's major earth science research and fact-finding agencies. By 1960, the continued growth of the Survey's natural resources and environmental programs and activities led to the...
Procedure for estimating the temperature of a hot-water component in a mixed water by using a plot of dissolved silica versus enthalpy
A. H. Truesdell, R.O. Fournier
1977, Journal of Research of the U.S. Geological Survey (5) 49-52
A graphical method using a plot of dissolved silica versus enthalpy allows quick determination of the temperature of the hot-water component of a nonboiling thermal spring. The method is applicable to warm spring waters that either have not lost heat before mixing or have lost heat by separation of steam...
Application of a hydrometeorological model to the south-central Sierra Nevada of California
Wendell V. Tangborn, Lowell A. Rasmussen
1977, Journal of Research of the U.S. Geological Survey (5) 33-48
A hydrometeorological streamflow-prediction model (HM model) developed for the North Cascades of Washington has been tested in the south-central Sierra Nevada of California. Twenty-four drainages ranging in mean altitude from 770 to 3,160 metres, including several of the major ones such as those of the Kern, Kings, and Merced Rivers,...
