Late Devonian Alamo Impact, southern Nevada, USA: Evidence of size, marine site, and widespread effects
Jared R. Morrow, Charles Sandberg, Anita G. Harris
2005, Special Paper of the Geological Society of America 259-280
The early Late Devonian (early Frasnian) Alamo Impact targeted an oceanic, off-platform site in southern Nevada, excavating a crater with a final diameter of 44–65 km. The original crater is now dismembered and buried beneath younger rocks. Consequently, its size and site must be deduced through multiple converging lines of...
Feasibility of using benthic invertebrates as indicators of stream quality in Hawaii
Reuben H. Wolff
2005, Scientific Investigations Report 2005-5079
Macroinvertebrates were collected from 19 sites on 14 streams on the island of Oahu and from 9 sites on 7 streams on the island of Kauai to evaluate associations between macroinvertebrate assemblages and environmental variables and to determine whether or not it would be feasible, in future studies, to develop...

Edward R. German, James C. Adamski
2005, Scientific Investigations Report 2005-5052
Orange County, Florida, is continuing to experience a large growth in population. In 1920, the population of Orange County was less than 20,000; in 2000, the population was about 896,000. The amount of urban area around Orlando has increased considerably, especially in the northwest part of the County. The eastern...
Analysis of ground-water levels and associated trends in Yucca Flat, Nevada Test Site, Nye County, Nevada, 1951-2003
Joseph M. Fenelon
2005, Scientific Investigations Report 2005-5175
Almost 4,000 water-level measurements in 216 wells in the Yucca Flat area from 1951 to 2003 were quality assured and analyzed. An interpretative database was developed that describes water-level conditions for each water level measured in Yucca Flat. Multiple attributes were assigned to each water-level measurement in the database to...
Comparability of suspended-sediment concentration and total suspended-solids data for two sites on the L'Anguille River, Arkansas, 2001 to 2003

2005, Scientific Investigations Report 2005-5193
Suspended-sediment concentration and total suspended solids data collected with automatic pumping samplers at the L'Anguille River near Colt and the L'Anguille River at Palestine, Arkansas, August 2001 to October 2003 were compared using ordinary least squares regression analyses to determine the relation between the two datasets for each of the...
Preliminary integrated geologic map databases for the United States: Delaware, Maryland, New York, Pennsylvania, and Virginia
Connie L. Dicken, Suzanne W. Nicholson, John D. Horton, Scott A. Kinney, Gregory L. Gunther, Michael P. Foose, Julia A. L. Mueller
2005, Open-File Report 2005-1325
The growth in the use of Geographic Information Systems (GIS) has highlighted the need for regional and national digital geologic maps attributed with age and lithology information. Such maps can be conveniently used to generate derivative maps for purposes including mineral-resource assessment, metallogenic studies, tectonic studies, and environmental research....

S. E. Church, D.L. Fey, M. E. Marot
2005, Scientific Investigations Report 2005-5006
Geochemical studies of lake sediment from Eagle Rock Lake and upper Fawn Lake were conducted to evaluate the effect of mining at the Molycorp Questa porphyry molybdenum deposit located immediately north of the Red River. Two cores were taken, one from each lake near the outlet where the sediment was...
Southern California — Wildfires and debris flows
Water Resources Division, U.S. Geological Survey
2005, Fact Sheet 2005-3106
Wildland fires are inevitable in the western United States. Expansion of man-made developments into fire-prone wildlands has created situations where wildfires can destroy lives and property, as can the flooding and debris flows that are common in the aftermath of the fires. Fast-moving, highly destructive debris flows triggered by...

Geologic map of the Great Smoky Mountains National Park region, Tennessee and North Carolina
Scott Southworth, Art Schultz, Danielle Denenny
2005, Open-File Report 2005-1225
The geology of the Great Smoky Mountain National Park (GSMNP) region of Tennessee and North Carolina was studied from 1993 to 2003 as part of a cooperative investigation with the National Park Service (NPS). This work has been compiled as a 1:100,000-scale map derived from mapping done at 1:24,000 and...

Paul M. Buszka, Kathleen K. Fowler
2005, Scientific Investigations Report 2005-5066
In cooperation with the National Park Service, the U.S. Geological Survey investigated water quality of key water bodies at the Lincoln Boyhood National Memorial near Lincoln City in southwestern Indiana. The key water bodies were a stock pond, representing possible nonpoint agricultural effects on water quality; an ephemeral stream, representing...
Hydrothermal vent fluids, siliceous hydrothermal deposits, and hydrothermally altered sediments in Yellowstone Lake
W. C. Pat Shanks, Lisa Morgan, Laurie S. Balistrieri, Jeffrey C. Alt
2005, Conference Paper
Stable isotopic (dD and d18O) data indicate about 13% total evaporative concentration has occurred in Yellowstone Lake, yet lake waters are enriched in dissolved As, B, Cl, Cs, Ge, Li, Mo, Sb, and W by at least an order-of-magnitude relative to the flow-weighted composition of inflowing streams. We conclude that...

Joint analysis of visible and infrared images
Randolph L. Kirk, Laurence A. Soderblom, Glen E. Cushing, Timothy A. Tituus
2005, Photogrammetric Engineering and Remote Sensing (10) 1167-1178
Analysis of data combining daytime visible reflected, daytime IR emitted, and nighttime IR emitted images allows us to isolate the physical effects of topography, albedo, and thermal inertia. To a good approximation, these physical influences interact linearly so that maps showing topographic shading, albedo, and relative thermal inertia can be produced by...

Barry M. Freifeild, Robert C. Trautz, Yousif K. Kharaka, Tommy J. Phelps, Larry R. Myer, Susan D. Hovorka, Daniel J. Collins
2005, Journal of Geophysical Research Solid Earth (110)
A novel system has been deployed to obtain geochemical samples of water and gas, at in situ pressure, during a geologic CO2 sequestration experiment conducted in the Frio brine aquifer in Liberty County, Texas. Project goals required high-frequency recovery of representative and uncontaminated aliquots of a rapidly changing two-phase fluid...
