Height changes along selected lines through the Death Valley region, California and Nevada, 1905-1984
Robert O. Castle, Thomas D. Gilmore, James P. Walker, Susan A. Castle
2005, Open-File Report 2005-1133
Comparisons among repeated levelings along selected lines through the Death Valley region of California and adjacent parts of Nevada have disclosed surprisingly large vertical displacements. The vertical control data in this lightly populated area is sparse; moreover, as much as a third of the recovered data is so thoroughly contaminated...
Thermal maturity patterns (CAI and %Ro) in the Ordovician and Devonian rocks of the Appalachian basin in West Virginia
John E. Repetski, Robert T. Ryder, Katharine Lee Avary, Michael H. Trippi
2005, Open-File Report 2005-1078
The objective of this study is to enhance existing thermal maturity maps in West Virginia by establishing: 1) new subsurface CAI data points for the Ordovician and Devonian and 2) new %Ro and Rock Eval subsurface data points for Middle and Upper Devonian black shale units. Thermal maturity values for...
Major- and trace-element concentrations in soils from two continental-scale transects of the United States and Canada
David B. Smith, William F. Cannon, Laurel G. Woodruff, Robert G. Garrett, Rodney Klassen, James E. Kilburn, John D. Horton, Harley D. King, Martin B. Goldhaber, Jean M. Morrison
2005, Open-File Report 2005-1253
This report contains major- and trace-element concentration data for soil samples collected from 265 sites along two continental-scale transects in North America. One of the transects extends from northern Manitoba to the United States-Mexico border near El Paso, Tex. and consists of 105 sites. The other transect approximately follows the...
Flood of September 18-19, 2004 in the Upper Delaware River Basin, New York
Lloyd T. Brooks
2005, Open-File Report 2005-1166
The interaction between the remnants of tropical depression Ivan and a frontal boundary in the upper Delaware River basin on September 18-19, 2004, produced 4 to more than 6 inches of rainfall over a 5-county area within a 24-hour period. Significant flooding occurred on the East Branch Delaware River and...
Blind comparisons of shear-wave velocities at closely-spaced sites in San Jose, California: Proceedings of a Workshop held at the US Geological Survey, Menlo Park, May 3, 2004
Michael W. Asten, David M. Boore, editor(s)
2005, Open-File Report 2005-1169
Shear-wave velocities within several hundred meters of Earth's surface are important in specifying earthquake ground motions for engineering design. Not only are the shearwave velocities used in classifying sites for use of modern building codes, but they are also used in site-specific studies of particularly significant structures. Many are the...
Potentiometric surface of the upper Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 2004
Sandra L. Kinnaman
2005, Open-File Report 2005-1202
Introduction: This map depicts the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity in September 2004. Potentiometric contours are based on water-level measurements collected at 608 wells during the period September 14-October 1, near the end of the wet season....
Influence of Riparian Tree Phenology on Lower Colorado River Spring-Migrating Birds: Implications of Flower Cueing
Laura J. McGrath, Charles van Riper III
2005, Open-File Report 2005-1140
Executive Summary Neotropical migrant birds make choices about which habitats are most likely to provide successful foraging locations during migration, but little is known about how these birds recognize and process environmental clues that indicate the presence of prey species. Aspects of tree phenology, notably flowering of trees along the lower...
Using tracers to evaluate streamflow gain-loss characteristics of Terror Creek, in the vicinity of a mine-permit area, Delta County, Colorado, water year 2003
Cory A. Williams, Kenneth J. Leib
2005, Scientific Investigations Report 2005-5018
In 2003, the U.S. Geological Survey, in cooperation with Delta County, initiated a study to characterize streamflow gainloss in a reach of Terror Creek, in the vicinity of a mine-permit area planned for future coal mining. This report describes the methods of the study and includes results from a comparison...
Quantification and simulation of metal loading to the Upper Animas River, Eureka to Silverton, San Juan County, Colorado, September 1997 and August 1998
Suzanne S. Paschke, Briant A. Kimball, Robert L. Runkel
2005, Scientific Investigations Report 2005-5054
Drainage from abandoned and inactive mines and from naturally mineralized areas in the San Juan Mountains of southern Colorado contributes metals to the upper Animas River near Silverton, Colorado. Tracer-injection studies and associated synoptic sampling were performed along two reaches of the upper Animas River to develop detailed profiles of...
Literature Review and Annotated Bibliography: Water Requirements of Desert Ungulates
James W. Cain III, Paul R. Krausman, Steven S. Rosenstock, Jack C. Turner
2005, Open-File Report 2005-1141
Executive Summary Ungulates adapted to desert areas are able to survive extreme temperatures and limited water availability. This ability is largely due to behavioral, morphological, and physiological adaptations that allow these animals to avoid or tolerate extreme environmental conditions. The physiological adaptations possessed by ungulates for thermoregulation and maintenance of water...
Evaluation of Measurements Collected with Multi-Parameter Continuous Water-Quality Monitors in Selected Illinois Streams, 2001-03
George E. Groschen, Robin B. King
2005, Scientific Investigations Report 2005-5060
Eight streams, representing a wide range of environmental and water-quality conditions across Illinois, were monitored from July 2001 to October 2003 for five water-quality parameters as part of a pilot study by the U.S. Geological Survey (USGS) in cooperation with the Illinois Environmental Protection Agency (IEPA). Continuous recording multi-parameter water-quality...
Managing Fire in the Northern Chihuahuan Desert: A Review and Analysis of the Literature
Brooke S. Gebow, William L. Halvorson
2005, Open-File Report 2005-1157
Executive Summary This report began as a literature review (Gebow and Halvorson 2001) conducted for fire planners at Carlsbad Caverns National Park who were seeking information about (1) the natural state of park vegetation, (2) northern Chihuahuan Desert natural fire regimes, and (3) fire effects on park plant species. It is...
Hydrogeology of the Mogollon Highlands, central Arizona
John T.C. Parker, William C. Steinkampf, Marilyn E. Flynn
2005, Scientific Investigations Report 2004-5294
The Mogollon Highlands, 4,855 square miles of rugged, mountainous terrain at the southern edge of the Colorado Plateau in central Arizona, is characterized by a bedrock-dominated hydrologic system that results in an incompletely integrated regional ground-water system, flashy streamflow, and various local water-bearing zones that are sensitive to drought. Increased...
