Reconnaissance investigation of ground-water supply for Dora Belle Campground, Shaver Lake, California

At the request of the United States Forest Service, the Ground Water Branch of the United Stated Geological Survey made a reconnaissance of the geologic features and water resources of the Dora Belle Campground in Sierra National Forest on the shore of Shaver Lake, Fresno County, California. Basically, the water-supply problem at Dora Belle Campground is that the present supply obtained from a spring is not adequate to meet the present summer demand, and is of poor quality. Plans call for a considerable increase in camping facilities.. This, it is imperative that the present supply be augmented or, preferably, be replaced entirely. the Forest Service estimated the future peak demand to be about 25,00 gallons per day. On October 28, 1957, the writer examined the are in the company of C. H. Fankboner, Assistant Forest Engineer, Sierra National Forest, and Ben Dix, Construction and Maintenance Foreman, Pine Ridge District. Field work, done on October 28th and 29th, consisted of a brief geologic reconnaissance to determine the rock types and geologic structure, and a hydrologic reconnaissance consisting of a partial inventory of water walls and springs in the vicinity of the campground. A spring box near the western edge of Bell Diamond Meadow was pumped out with a Forest Service pump truck to determine its rate of recovery and potential production.

Development of ground water from the Carrizo sand and Wilcox group in Dimmit, Zavala, Maverick, Frio, Atacosa, Median, Bexar, Live Oak, McMullen, La Salle, and Webb Counties, Texas

The development of ground water for irrigation from the Carrizo sand south and southwest of San Antonio, Tex., has increased rapidly during the past few years. Declining pumping water levels in irrigation wells, caused by increased withdrawals, have caused considerable concern among the residents of the area. In response, the Nueces River Conservation and Reclamation District entered into a cooperative agreement with the Texas Board of Water Engineers and the United States Geological Survey to determine the extent of development and the rate of withdrawal that has cause the decline. All wells that discharged more than 150 gallons per minute for extended periods of time in 1955 from either the Carrizo sand or sands of the Wilcox group were studied and are shown on [late 1. Estimates were made of the total withdrawals by county and are given in table 2. Similar estimates of withdrawals in some of the counties for the irrigation years 1929-30, 1938-39, 1944-45, and 1947-48 are presented for comparison in table 3. Although the Carrizo sand is the principal source of ground water pumped in the area, estimate of withdrawals of water from the Wilcox were included in this inventory because (1) the formation appears to be hydraulically connected to the Carrizo sand, (2) the quality of water generally is good in the outcrop area of the Wilcox, and (3) appreciable withdrawals are being made from the Wilcox for irrigation in a few areas. The investigation covered an area of about 7,500 square miles and included all or parts of the following counties: Dimmit, Zavala, Maverick, Frio, Atascosa, Medina, Bexar, Live Oak, McMullen, La Salle, and Webb (fig. 1).

Seismic investigations in Wyoming as part of the Wagon Wheel definition studies

As part of the Wagon Wheel definition studies, seismic investigations were conducted in Wyoming by personnel of the United States Geological Survey, Las Vegas, Nevada. From March 22, 1973 to February 22, 1974, a seismograph station recorded seismic activity at five different areas in the vicinity of the proposed Project Wagon Wheel location in the Green River basin of Wyoming. The short period vertical component station, located near and around ground zero (GZ) operated for approximately two months at each of five locations at distances from 3 to 21 km from GZ. One hundred and twenty nine (129) natural and man -made events identifiable as located within a radius of 100 km from the station were recorded during tile eleven-month study. Calculated magnitudes ranged from M L - 0. 6 toM L 2.6.

Shallow sedimentary framework of Georges Bank

Two thousand nine hundred kilometers of minisparker data were collected on Georges Bank by the United States Geological Survey during October of 1975. Several sedimentary features have been observed in the data, The bank is recognized as a compound feature resulting from erosion of Tertiary coastal-plain strata followed by deposition of an extensive sediment wedge on the western flank of the cuesta. Marine planation (probably Late Pleistocene) truncated this bank morphology producing an erosion surface roughly paralleling the present sea floor. The truncated bank surface is blanketed by a veneer of complex Late Pleistocene drift which masks underlying features and is being reworked by modern processes. Present bank morphology is inferred-to be arather recent development. A proper understanding of the significance of complex bank sediments with respect to the potential geologic hazards of drilling or placement of bottom. supported structures necessitates a more detailed seismic reflection program, in conjunction with geotechnical analysis of core-samples.

A compilation of data from the July, 1976 Oroville, California seismic-refraction experiment

The August 1, 1975, Oroville, California, earthquake (M b = 5.7) and its aftershocks focused considerable interest on current tectonic processes operating in the western foothills of the Sierra Nevada range. As part of an intensive study of this earthquake sequence, the United States Geological Survey with support from the California Department of Water Resources conducted a seismic refraction experiment during July 1976 in the Oroville region. The objective of the experiment is to resolve more clearly the P- and S-wave velocity structure of the crust in the region as a basis for both more accurate hypocenter locations and evidence on the physical properties at depth within the crust.

Maps showing formation temperatures and configurations of the tops of the Minnelusa Formation and the Madison Limestone, Powder River basin, Wyoming, Montana, and adjacent areas

This report is part of a study to describe the hydrogeologic framework needed to evaluate the water resources of the Paleozoic age aquifers in the Northern Great Plains coal region. Preliminary studies by the U.S. Geological Survey and State agencies in Wyoming, Montana, and South Dakota have indicated that these aquifers might provide a significant percentage of the water requirements for coal development. Geologic and water-temperature data for the Minnelusa Formation of Permian and Pennsylvanian age and for the Madison Limestone (Group where it is subdivided) of Mississippian and locally late Devonian age , and their equivalents, were compiled and interpreted. Maps were produced showing the altitude and ground-water temperatures of the top of these formations. The altitude (configuration) maps show the depth and position of the formations throughout the area. Temperature maps can be used to calculate changes in the viscosity of water caused by large temperature differences. The viscosity differences will be useful in adjusting calculated transmissivity aquifer values (the rate at which water can be transmitted through an aquifer). (Woodard-USGS)

Exploratory drilling during 1979 in the McCallum coal field, Jackson County, Colorado

Rotary drilling of two drill holes in the McCallum coal field, Jackson County, Colorado, was completed by the United States Geological Survey (USGS) in July 1979. The holes are within the area of the short-term lease application. C-27931 held by Wyoming Fuels of Lakewood, Colorado. Drill-hole GNW1 is located in T. 3 N., R. 78 W., sec. 10, SIANE14, in the Gould NW quadrangle, and drill-hole JMM2 is located in T. 8 N., R. 78 W., sec. 10, SW 1 / 2 NE 1 / 4 , in the Johnny Moore Mountain quadrangle (fig. 1). The area is part of the McCallum Known Recoverable Coal Resource Area (KRCRA). The purpose of the drilling was to gather additional data concerning depth, thickness, and extent of the Sudduth coal bed in order to calculate a reserve base for the area of the lease application. USGS personnel chose the drill-hole sites, conducted the geophysical logging, and recorded the descriptions of cuttings at 5-foot intervals.

Analytical method codes and descriptions for well and outcrop samples: Eastern Gas Shales Project data system

The United States Geological Survey and Petroleum Information Corporation (PI) of Denver have created a large computerized file of sample data for the Eastern Gas Shales Project (EGSP) as a responsibility to the U.S. Department of Energy (DOE), Morgantown Energy Technology Center (METC), Morgantown, West Virginia. The EGSP was initiated in 1976 by METC to investigate gas resources in Devonian shales found in the Appalachian basin. An objective of the EGSP is to accumulate a data base characterizing these shale units which can be used to assess future development of the gas resource. More than 30 government and industry participants served as contractors and contributed data from their research.

Precambrian basement map of the northern Midcontinent, U.S.A.

The northern midcontinent region includes the buried basement of the interior platform and the southernmost exposed Precambrian rocks of the Canadian Shield (see index map). Structurally, it is part of a continent-wide "tectonic collage" consisting of (1) Archean cratonic elements (>2500 Ma) and remnants of Early Proterozoic (-1,900-2,100 Ma) cratonic cover, (2) anastomosing Early Proterozoic orogenic belts culminating at 1,850 Ma and -1,650 Ma, which partly enclose and marginally affect the Archean cratons, and (3) intracratonic igneous and sedimentary rocks, mainly of Middle Proterozoic age but including an older rhyolite-granite terrane (-1,760 Ma) and somewhat younger, scattered quartzite, assigned by Dott (1983) to the "Baraboo interval". The map was compiled as part of a cooperative federal-state project from 1:500,000-scale maps submitted by respective state geological surveys showing basement drill holes, lithotypes or sketchy geologic map units, and basement topography, contoured at 200-foot intervals. In compiling the map, available aeromagnetic (Zietz, 1982; Burchett, 1985) and gravity anomaly maps (Hildenbrand and others, 1982) were utilized to define insofar as possible the trend, extent, and boundaries of individual rock bodies, and all available isotopic age data were used. The principal geologic contribution resulting from the compilation is the delineation of a major buried, northwest-trending Early Proterozoic orogen, named the Central Plains orogen (Sims and Peterman, in press). It extends from Nebraska through Kansas into Missouri, where it is overlapped by Middle Proterozoic rhyolite-granite terranes; and it sharply truncates Archean rocks and an older Proterozoic orogenic (Penokean) belt in the inner part of the craton.

Worldwide Assessment of the Status of Seismic Zonation, Fourth International Forum on Seismic Zonation, Proceedings

We are pleased to provide you with information developed for the Fourth International Forum on Seismic Zonation which will be convened in two locations year in conjunction two major international meetings. The objectives are: 1) to assess the status of seismic zonation in every country of the world, 2) to evaluate the reasons for advances and new initiatives, and 3) to foster continued cooperation. Seismic zonation is the process that leads to risk reduction and sustainability of new development. It is based on the division of a geographic region into smaller areas or zones on the basis of an integrated assessment of the hazard, built, and policy environments of the region. Seismic zonation depends on hazard mapping performed on national/regional, subregional, and urban (i.e., microzonation) scales depending on the particular application. We gratefully acknowledge the written communications of many professionals who responded to our request for information. Also, we acknowledge the use of information contained in five valuable reports (see directories in the Appendices for information on where to obtain copies of the reports): 1.

USGS response to an urban earthquake, Northridge '94

The urban centers of our Nation provide our people with seemingly unlimited employment, social, and cultural opportunities as a result of the complex interactions of a diverse population embedded in an highly-engineered environment. Catastrophic events in one or more of the natural earth systems which underlie or envelop urban environment can have radical effects on the integrity and survivability of that environment. Earthquakes have for centuries been the source of cataclysmic events on cities throughout the world. Unlike many other earth processes, the effects of major earthquakes transcend all political, social, and geomorphic boundaries and can have decided impact on cities tens to hundreds of kilometers from the epicenter. In modern cities, where buildings, transportation corridors, and lifelines are complexly interrelated, the life, economic, and social vulnerabilities in the face of a major earthquake can be particularly acute. The 1994 Northridge Earthquake was a major test for parts of what many consider the most earthquake-prepared and best-engineered metropolitan region in the United States. While the combined efforts of concerned professionals at all levels of government, academia, and the private sector have produced significant advances in our knowledge of the causes and potential effects of earthquakes, and of ways to reduce their impact, it remains unfortunately true that actual earthquakes provide important opportunities to test those advances in our knowledge. In the hours and days following the Northridge Earthquake, the four Federal member agencies of the National Earthquake Hazards Reduction Program (NEHRP), the Federal Emergency Management Agency (FEMA), the National Institute for Standards and Technology (NIST), the National Science Foundation (NSF), and the United States Geological Survey (USGS) laid out a detailed plan for collecting, analyzing, archiving, and reporting information that would benefit the Nation in future earthquake hazards reduction efforts. Congress provided a special appropriation to FEMA to carry out this plan and FEMA distributed those funds to the four NEHRP agencies. The USGS was responsible for conducting geophysical and geological investigations in support of the NEHRP Post-earthquake Study. For the past 2 years, the USGS has rigorously pursued over 40 tasks focused on the USGS Northridge Earthquake Mission. This document is a summary report of the USGS findings; additional technical reports on specific USGS tasks are appearing in various scientific journals and USGS publications.

Physical characteristics of dungeness crab and halibut habitats in Glacier Bay

In Glacier Bay National Park, Alaska there are ongoing studies of Dungeness Crab (Cancer magister) and Pacific Halibut (Hippoglosus stenolepis). Scientists of the United States Geological Survey (USGS) are attempting to ascertain life history, distribution, and abundance, and to determine the effects of commercial fishing in the park (Carlson et al., 1998). Statistical sampling studies suggest that seafloor characteristics and bathymetry affect the distribution, abundance and behavior of benthic species. Examples include the distribution of Dungeness crab which varies from 78 to 2012 crabs/ha in nearshore areas to depths of 18 m (O'Clair et al., 1995), and changes in halibut foraging behavior according to bottom type (Chilton et al., 1995). This report discusses geophysical data collected in six areas within the park in 1998. The geophysical surveying done in this and previous studies will be combined with existing population and sonic-tracking data sets as well as future sediment sampling, scuba, submersible, and bottom video camera observations to better understand Dungeness crab and Pacific halibut habitat relationships.

Loch Vale Watershed Project quality assurance report, 1995-1998

The Loch Vale Watershed (LVWS) project was initiated in 1980 by the National Park Service with funding from the Aquatic Effects Research Program of the National Acid Precipitation Assessment Program. Initial research objectives were to understand the processes that would either mitigate or accelerate the effects of pollution on soil and surface water chemistry, and to build a record in which long-term trends could be identified and examined. It is important for all data collected in Loch Vale to meet the high standards of quality set forth in previous LVWS QA/QC reports and LVWS Methods Manuals. Given the ever-widening usage of data collected in Loch Vale, it is equally important to provide users of that data with a report assuring that all data are sound. Parameters covered in this report are the quality of meteorological measurements, hydrological measurements, surface water chemistry, and similarities in catch efficiency of two raingage types in Loch Vale for the period of 1995-1998. Routine sampling of weather conditions, precipitation chemistry, and stream/lake water chemistry began in 1982. Since then, all samples and data have been analyzed according to widely accepted and published methods. Weather data have been collected, analyzed, and stored by LVWS project personnel. Methods for the handling of meteorological data are well documented (Denning 1988, Edwards 1991, Newkirk 1995,and Allstott 1995). Precipitation chemistry has always been collected according to National Atmospheric Deposition Program protocol (Bigelow 1988), and analyzed at the Central Analytical Laboratory of the Illinois State Water Survey in Champaign, IL. QA/QC procedures of the National Atmospheric Deposition Program are well documented (Aubertin 1990). Protocols for sampling surface waters are also well documented (Newkirk 1995). Analysis of surface water chemistry has been performed using standard EPA protocol at the US Forest Service's Rocky Mt. Station Biogeochemistry Laboratory since 1993.

McVCO handbook 1999

McVCO is a microcontroller-based frequency generator that replaces the voltage controlled oscillator (VCO) used in the analog telemetry of seismic data. It accepts low-level signals from a seismometer and produces a frequency modulated subcarrier suitable for radio or telephone links to a data collection site. McVCO was designed for the purpose of improving the analog telemetry of signals within the Pacific Northwest Seismograph Network (PNSN). Its development received support from the University of Washington Geophysics Program, and both the Volcano Hazards and Earthquake Hazards programs of the United States Geological Survey (USGS). This handbook covers operation of McVCO, provides a technical reference for those who require a closer look at how McVCO works, and covers a collection of topics that need explicit treatment or that spring from deployment of the instrument.
