Comparison of fire fuel maps produced using MSS and AVHRR data
Wayne A. Miller, David C. Johnston
1985, Conference Paper, Pecora 10 Symposium
The fuel information, in support of the Bureau of Land Management's (BLM) national fire program, has been obtained through the manila interpretation of Landsat multi-spectral scanner images and digital image analysis of Advanced Very High Resolution Radiometer (AVHRR) data. The BLM, in cooperation with the Earth Resources Observation Systems...
Organochlorine concentrations, whole body weights, and lipid content of black skimmers wintering in Mexico and in south Texas, 1983
Donald H. White, C. A. Mitchell, C. J. Stafford
1985, Bulletin of Environmental Contamination and Toxicology (34) 513-517
Since 1978, a large proportion of the black skimmers (Rynchops niger) nesting along the Texas coast have had high concentrations of DDE in their eggs. Of 284 eggs collected from 5 sites during 1978-81, 99.5% contained detectable (> 0.i0 ppm) w levels of DDE, ranging up to 86 ppm wet-weight;...

Warren J. Nokleberg, D. L. Jones, Norman J. Silberling
1985, GSA Bulletin (96) 1251-1270
Major portions of the eastern Alaska Range, south of the Denali fault, in the McCarthy, Nabesna, Mount Hayes, and eastern Healy quadrangles, consist predominantly of the Maclaren and Wrangellia tectono-stratigraphic terranes. The Maclaren terrane consists of the Maclaren Glacier metamorphic belt and the regionally deformed and metamorphosed East Susitna batholith....

1985, Economic Geology (80) 1896-1926
Similar stratiform sphalerite-galena-barite deposits occur in the Red Dog Creek area, De Long Mountains quadrangle, and in the Drenchwater Creek area, Howard Pass quadrangle, northwestern Brooks Range, Alaska. The deposits, located approximately 180 km apart, are hosted by Mississippian and Pennsylvanian strata of the Kagvik structural sequence of late Paleozoic...
Recent Red-shouldered Hawk range expansion north into Oregon including first specimen record
Charles J. Henny, John E. Cornely
1985, Murrelet (66) 29-31
In this paper we review 46 Red-shouldered Hawk (Buteo lineatus) observation records from Oregon between 1971 and 1983. The literature contained only two records prior to 1971: Johnson's (1880) record without a specific date or locality from the Willamette Valley of western Oregon, and Bendire's (1892) two nests located...

G.M. Haramis, J.R. Goldsberry, D.G. McAuley, E.L. Derleth
1985, Journal of Wildlife Management (49) 449-454
We used conventional 35-mm photography to conduct an aerial photographic census of canvasbacks (Aythya valisineria) throughout Chesapeake Bay (tidal Maryland and Virginia) and coastal North Carolina, 26-30 January 1981. Flock size and sex ratio characteristics were determined from examination of color transparencies of 165 canvasback flocks totaling over 95,000 birds....
Composition and morphology of ferromanganese coatings on glacial erratics in Lydonia Canyon, United States East Coast
L. J. Poppe, Dennis W. O’Leary, R.F. Commeau
1985, Geo-Marine Letters (5) 127-133
Ferromanganese coatings have been found on glacial erratics in Lydonia Canyon, off the United States northeastern coast. The coatings, which are about 17 ??m thick, consist of an outer manganese-rich layer which covers the top of the erratic, a middle transitional layer, and an internal iron-rich layer that encircles the...

Ground-water flow in the Prairie du Chien-Jordan aquifer related to contamination by coal-tar derivatives, St. Louis Park, Minnesota
J. R. Stark, M. F. Hult
1985, Water-Resources Investigations Report 85-4087
A three-dimensional, ground-water-flow model of the Prairie du Chien-Jordan aquifer and associated hydrogeologic units was developed to evaluate the movement of coal-tar derivatives from a coal-tar distillation and wood-preserving plant in St. Louis Park, Minnesota. A finite-difference grid was superimposed on the modeled area, which includes most of eastern Hennepin...
Geohydrology of the aquifer in the Santa Fe Group, northern West Mesa of the Mesilla Basin near Las Cruces, New Mexico
R. G. Myers, B. R. Orr
1985, Water-Resources Investigations Report 84-4190
Because of the heterogeneity of the Santa Fe Group, New Mexico, the hydrologic characteristics of the aquifer vary substantially from place to place. Hydraulic conductivities of 12 and 30 feet per day were estimated from aquifer tests for two wells in the eastern one-half of the study area. Well yields...
Hydrologic and geochemical monitoring in Long Valley caldera, Mono County, California, 1982-1984
C. D. Farrar, M.L. Sorey, S. Rojstaczer, C. J. Janik, Robert H. Mariner, T. L. Winnett, M. D. Clark
1985, Water-Resources Investigations Report 85-4183
The Long Valley caldera is a potentially active volcanic area on the eastern side of the Sierra Nevada in east-central California. Hydrologic and geochemical monitoring of surface and subsurface features began in July 1982 to determine if changes were occurring in response to processes causing earthquakes and crustal deformation. Differences...
Major and trace-element analyses of acid mine waters in the Leviathan Mine drainage basin, California/Nevada; October, 1981 to October, 1982
J.W. Ball, D. Kirk Nordstrom
1985, Water-Resources Investigations Report 85-4169
Water issuing from the inactive Leviathan open-pit sulfur mine has caused serious degradation of the water quality in the Leviathan/Bryant Creek drainage basin which drains into the East Fork of the Carson River. As part of a pollution abatement project of the California Regional Water Quality Control Board, the U.S....
Isotopic studies of the late Archean plutonic rocks of the Wind River Range, Wyoming
J. S. Stuckless, C. E. Hedge, R. G. Worl, K. R. Simmons, Ignatius T. Nkomo, D. B. Wenner
1985, Geological Society of America Bulletin (96) 850-860
Isotopic studies of the Rb-Sr and U-Th-Pb systems in whole-rock samples and the U-Pb systematics for zircons document the existence of two late Arehean intrusive events in the Wind River Range. All of the systems examined indicate an age of ∼2,630 ± 20...
Petrology and tectonic significance of augen gneiss from a belt of Mississippian granitoids in the Yukon-Tanana terrane, east- central Alaska
Cynthia Dusel-Bacon, John N. Aleinikoff
1985, Geological Society of America Bulletin (96) 411-425
An approximately E-W-trending belt of porphyritic peraluminous granitic rocks, metamorphosed and deformed to augen gneiss, is exposed for 400 km across the Yukon-Tanana terrain. Chemical, textural, and isotopic data from large augen-gneiss bodies indicate that these bodies originated as early Mississippian granitic rocks that assimilated, or were anatectically derived from,...

J. F. Sutter, N. M. Ratcliffe, S.B. Mukasa
1985, Geological Society of America Bulletin (96) 123-136
40Ar/39Ar ages of coexisting biotite and hornblende from Proterozoic Y gneisses of the Berkshire and Green Mountain massifs, as well as 40Ar/39Ar and K-Ar mineral and whole-rock ages from Paleozoic metamorphic rocks, suggest that the thermal peak for the dominant metamorphic recrystallization in western New England occurred 465 ± 5 m.y....

Michael L. Sorey
1985, Conference Paper, Transactions - Geothermal Resources Council
Results of test drilling to depths of 2 km and data on the chemical and isotopic content of waters from hot springs and fumaroles permit a conceptual model of the present-day hydrothermal system in Long Valley caldera to be delineated. The model consists of two principal zones in which hot...
DISTRIBUTION OF TRACE ELEMENTS IN COAL MINERALS OF SELECTED EASTERN UNITED STATES COALS.
C.A. Palmer, M.-V. Wandless
1985, Conference Paper
The association of 34 elements with minerals found in coal was determined by a combination of analytical techniques on size and density fractions of low-temperature ash (LTA). Instrumental neutron activation analysis was used to determine the concentrations of the elements, and X-ray diffraction analysis, scanning electron microscopy, and scanning transmission...
