Structure and kinematics of a complex impact crater, Upheaval Dome, southeast Utah
Bryan J. Kriens, Eugene Merle Shoemaker, Kenneth E. Herkenhoff
1997, Brigham Young University Geology Studies (42) 19-31
Two vastly different phenomena, impact and salt diapirism, have been proposed for the origin of Upheaval Dome, southeast Utah. Detailed geologic mapping, seismic refraction data, and the presence of shock metamorphosed rocks indicate that the dome originated by collapse of a transient cavity formed by impact. Evidence is: (1) the...
Design and implementation of the National Water-Quality Assessment Program: a United States example: understanding the limitations of using compliance-monitoring data to assess the water quality of a large river basin
David J. Wangsness
1997, Book chapter, Protecting Danube River Basin resources: ensuring access to water quality data and information
In the 1980s it was determined that existing ambient and compliance-monitoring data could not satisfactorily evaluate the results of hundreds of billions of dollars spent for water-pollution abatement in the United States. At the request of the US Congress, a new programme, the National Water-Quality Assessment, was designed and implemented...
Two new species of Scolecopteris (Marattiales), sources of Torispora securis Balme and Thymospora thiessenii (Kosanke) Wilson et Venkatachala
Alicia D. Lesnikowska, Debra A. Willard
1997, Review of Palaeobotany and Palynology (95) 211-225
Two biostratigraphically significant miospore species, Thymospora thiessenii and Torispora securis, were isolated from marattialean synangia preserved in coal-ball permineralizations from Pennsylvanian strata of the Illinois Basin and Western Interior coal region. Synangia containing Thymospora thiessenii were recovered from the Missourian Parker Coal Member (Patoka Formation) of Indiana and...

Natural disasters: forecasting economic and life losses
Stuart P. Nishenko, Christopher C. Barton
1997, Report
Events such as hurricanes, earthquakes, floods, tsunamis, volcanic eruptions, and tornadoes are natural disasters because they negatively impact society, and so they must be measured and understood in human-related terms. At the U.S. Geological Survey, we have developed a new method to examine fatality and dollar-loss data, and to make...
Tests of ground-penetrating radar and induced polarization for mapping fluvial mine tailings on the floor of the Couer d'Alene River, Idaho
David L. Campbell, Jefferey C. Wynn, Stephen E. Box, Arthur A. Bookstrom, Robert Horton
1997, Book, Proceedings of the Symposium on the Application of geophysics to engineering and environmental problems: SAGEEP '97
In order to investigate sequences of toxic mine tailings that have settled in the bed of the Coeur d'Alene River, Idaho, (see figure 1) we improvised ways to make geophysical measurements on the river floor. To make ground penetrating radar (GPR) profiles, we mounted borehole antennas on a skid that...
Interpretive geologic bedrock map of the Tanana B-1 Quadrangle, Central Alaska

This report provides detailed (1:63,360-scale) mapping of the Tanana B-1 Quadrangle (250 square miles; equivalent to four 7.5 minute quadrangles). The area is part of the Manley Hot Springs-Tofty mining districts and adjacent to the Rampart mining district to the north of the Tanana A-1 and A-2 Quadrangles. This report...

Age and correlation of tephra layers, position of the Matuyama-Brunhes chron boundary, and effects of Bishop Ash eruption on Owens Lake, as determined from drill hole OL-92, Southeast California
Andrei M. Sarna-Wojcicki, Charles E. Meyer, Elmira Wan
1997, Book chapter, An 800,000-year paleoclimatic record from core OL-92, Owens Lake, Southeast California
Tephra layers in the ~323-m-deep Owens lake drill hole OL-92 correlate to tephra layers that have been identified and dated elsewhere in the western United States. Tephra layers identified are the Bishop ash bed (758 ka) at 309.2–298.6 m; the Dibekulewe (ash) bed (ca. 470 ka to ca. 610 ka)...

National Mineral-Resource Assessment: The 1996 estimate of undiscovered gold, silver, copper, lead, and zinc remaining in the United States
Joseph A. Briskey Jr., Paul G. Schruben
1997, Report
Mining has occurred in the United States from pre-Revolutionary times. How much of our Nation's total mineral wealth has already been discovered? How much is left? For conventional-type deposits that contain gold, silver, copper, lead, or zinc, about as much is left to be discovered in the conterminous 48 States...
Synthesis of the paleoclimatic record from Owens Lake core OL-92
George I. Smith, James L. Bischoff, J. Platt Bradbury
1997, Book chapter, An 800,000-year paleoclimatic record from core OL-92, Owens Lake, Southeast California
During much of the late Quaternary, Owens Lake overflowed into one or more of four successively lower-elevation basins. Most of the water came from the high, eastern slopes of the southern Sierra Nevada, and changes in the volumes of that water reflect a dominant climatic cycle of ~100 k.y. Variations...
Climate control
Thomas M. Cronin
1997, Chesapeake Bay Journal (1) 4-7
April showers bring May flowers. Well, not always. The climate of the Chesapeake Bay area, as elsewhere, varies from year to year as anyone living in the watershed the last few years can attest.That variability, though, is more than just a conversation ice-breaker. Fluctuations in seasonal rainfall affect river flows...
An 800,000-year pollen record from Owens Lake, California: Preliminary analyses

1997, Book chapter, An 800,000-year paleoclimatic record from core OL-92, Owens Lake, Southeast California
A long sequence of fossil palynomorph assemblages from a 323-m-long core taken at Owens Lake has enabled us to evaluate the gross vegetational trends for the Owens Valley region of California over the past ~800,000 years. Shifts in vegetation composition and abundance in the study area during the Pleistocene were...

We provide an overview of new ground-motion relations for eastern North America (ENA) developed over the last five years. The empirical-stochastic relations of Atkinson and Boore (1995) are compared to relations developed by the Electric Power Research Institute (EPRI, 1993; also Toro et al., 1994), Frankel et al. (1996), and the consensus ENA...
