2008, Open-File Report 2008-1337
Lack of recruitment and canopy replacement of aspen (Populus tremuloides) stands that grow on the edges of grasslands on the low-elevation elk (Cervus elaphus) winter range of Rocky Mountain National Park (RMNP) in Colorado have been a cause of concern for more than 70 years. We used a combination of...

Regression method for estimating long-term mean annual ground-water recharge rates from base flow in Pennsylvania
Dennis W. Risser, Ronald E. Thompson, Marla H. Stuckey
2008, Scientific Investigations Report 2008-5185
A method was developed for making estimates of long-term, mean annual ground-water recharge from streamflow data at 80 streamflow-gaging stations in Pennsylvania. The method relates mean annual base-flow yield derived from the streamflow data (as a proxy for recharge) to the climatic, geologic, hydrologic, and physiographic characteristics of the basins...

Myung W. Lee, Timothy S. Collett, Warren F. Agena
2008, Scientific Investigations Report 2008-5175
Gas-hydrate resource assessment on the Alaska North Slope using 3-D and 2-D seismic data involved six important steps: (1) determining the top and base of the gas-hydrate stability zone, (2) 'tying' well log information to seismic data through synthetic seismograms, (3) differentiating ice from gas hydrate in the permafrost interval,...

The U.S. Geological Survey, in cooperation with the Houston-Galveston Area Council and the Galveston Bay Estuary Program under the authority of the Texas Commission on Environmental Quality, did a study in 2007 to assess the variation in biotic assemblages (benthic macroinvertebrate and fish communities) and stream-habitat data with sampling strategy...
Landslides Mapped from LIDAR Imagery, Kitsap County, Washington
Jonathan P. McKenna, David J. Lidke, Jeffrey A. Coe
2008, Open-File Report 2008-1292
Landslides are a recurring problem on hillslopes throughout the Puget Lowland, Washington, but can be difficult to identify in the densely forested terrain. However, digital terrain models of the bare-earth surface derived from LIght Detection And Ranging (LIDAR) data express topographic details sufficiently well to identify landslides. Landslides and escarpments...

Earthquakes generated from bedding plane-parallel reverse faults above an active wedge thrust, Seattle fault zone
Harvey Kelsey, Brian L. Sherrod, Alan R. Nelson, Thomas M. Brocher
2008, GSA Bulletin (120) 1581-1597
A key question in earthquake hazard analysis is whether individual faults within fault zones represent independent seismic sources. For the Seattle fault zone, an upper plate structure within the Cascadia convergent margin, evaluating seismic hazard requires understanding how north-side-up, bedding-plane reverse faults, which generate late Holocene fault scarps, interact with...

Effects of environmental factors on incubation patterns of Greater Sage-Grouse
Peter S. Coates, David J. Delehanty
2008, The Condor (110) 627-638
Birds in which only one sex incubates the eggs are often faced with a direct conflict between foraging to meet metabolic needs and incubation. Knowledge of environmental and ecological factors that shape life-history strategies of incubation is limited. We used continuous videography to make precise measurements of female Greater Sage-Grouse...
Latitudinal variation in cold hardiness in introduced Tamarix and native Populus
Jonathan M. Friedman, James E. Roelle, John F. Gaskin, Alan E. Pepper, James R. Manhart
2008, Evolutionary Applications (1) 598-607
To investigate the evolution of clinal variation in an invasive plant, we compared cold hardiness in the introduced saltcedar (Tamarix ramosissima, Tamarix chinensis, and hybrids) and the native plains cottonwood (Populus deltoidessubsp. monilifera). In a shadehouse in Colorado (41°N), we grew plants collected along a latitudinal gradient in the central...
Use of Superposition Models to Simulate Possible Depletion of Colorado River Water by Ground-Water Withdrawal
Stanley A. Leake, William Greer, Dennis Watt, Paul Weghorst
2008, Scientific Investigations Report 2008-5189
According to the 'Law of the River', wells that draw water from the Colorado River by underground pumping need an entitlement for the diversion of water from the Colorado River. Consumptive use can occur through direct diversions of surface water, as well as through withdrawal of water from the river...

The USGS, in cooperation with the Ohio Emergency Management Agency, conducted a study in the Wheeling Creek Basin to (1) evaluate and contrast land-cover characteristics from 2001 with characteristics from 1979 and 1992; (2) compare current streambed elevation, slope, and geometry with conditions present in the late 1980s; (3) look...
Results of Gravity Fieldwork Conducted in March 2008 in the Moapa Valley Region of Clark County, Nevada
Daniel S. Scheirer, Arne Dossing Andreasen
2008, Open-File Report 2008-1300
In March 2008, we collected gravity data along 12 traverses across newly-mapped faults in the Moapa Valley region of Clark County, Nevada. In areas crossed by these faults, the traverses provide better definition of the gravity field and, thus, the density structure, than prior gravity observations. Access problems prohibited complete...
