Normal annual precipitation is less than 8 to about 10 in. over much of the region (Cooley and others, 1969). Generally, water supplies for residents on the Reservation come from wells and springs, but locally, these supplies are small and, in some areas, they are slightly to moderately saline and not suitable for domestic purposes (Naftz and Spangler, 1994). One such area where water supply is limited is Monument Valley, along the Utah-Arizona State line, in the northern part of the Navajo Indian Reservation.\r\n\r\nThe main issue identified by the Navajo Nation Department of Water Resources (DWR) concerns adequate water supply for the residents of the Monument Valley area. Additional water sources need to be developed locally to avoid having water piped into the area and to minimize haulage of water for domestic use. In addition, supplemental water supplies need to be developed to meet the demands of an increasing number of tourists. Because of these needs, the Navajo Nation DWR, in cooperation with the U.S. Geological Survey, investigated the hydrology of, and quality of water in, an alluvial aquifer along a tributary of Oljato Wash, near Oljato, Utah.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/wri994074","collaboration":"Prepared in cooperation with the Navajo Nation Department of Water Resources","usgsCitation":"Spangler, L.E., and Johnson, M., 1999, Hydrology and Water Quality of the Oljato Alluvial Aquifer, Monument Valley Area, Utah and Arizona (Version 1.0): U.S. Geological Survey Water-Resources Investigations Report 99-4074, 2 Plates: both 23 x 35 inches, https://doi.org/10.3133/wri994074.","productDescription":"2 Plates: both 23 x 35 inches","additionalOnlineFiles":"Y","costCenters":[{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true}],"links":[{"id":164009,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":9773,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri994074/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -110.33333333333333,36.5 ], [ -110.33333333333333,37.166666666666664 ], [ -110,37.166666666666664 ], [ -110,36.5 ], [ -110.33333333333333,36.5 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67e914","contributors":{"authors":[{"text":"Spangler, Larry E.","contributorId":78602,"corporation":false,"usgs":true,"family":"Spangler","given":"Larry","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":204615,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Johnson, M.S.","contributorId":49382,"corporation":false,"usgs":true,"family":"Johnson","given":"M.S.","email":"","affiliations":[],"preferred":false,"id":204614,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":35510,"text":"b2174A - 1999 - Organic metamorphism in the California petroleum basins; Chapter A, Rock-Eval and vitrinite reflectance","interactions":[],"lastModifiedDate":"2012-02-02T00:09:50","indexId":"b2174A","displayToPublicDate":"2000-04-01T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":306,"text":"Bulletin","code":"B","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2174","chapter":"A","title":"Organic metamorphism in the California petroleum basins; Chapter A, Rock-Eval and vitrinite reflectance","docAbstract":"The results of ROCK-EVAL and vitrinite reflectance analyses\r\nof a large sample base from more than 70 wells located in\r\nthree oil-rich California petroleum basins are reported. The\r\ncores from these wells have a wide range of present-day burial\r\ntemperatures (40\r\n?\r\nto 220\r\n?\r\nC). The rocks in these basins were\r\ndeposited under highly variable conditions, sometimes resulting\r\nin substantially different organic matter (OM) types in rocks tens\r\nof meters vertically apart from each other in one well. The\r\nkinetic response of these different OM types to equivalent wellknown\r\nburial histories is a pivotal point of this study.\r\nIn the Los Angeles and Ventura Basins, rock organic-richness\r\nsignificantly increased with depth, as did kerogen hydrogen\r\ncontent, and the percentage of fine-grained versus coarsegrained\r\nrocks. The shales in these basins are perceived as containing\r\nprimarily hydrogen-rich amorphous OM. In actuality,\r\nthe shallowest 2,000 to 3,000 m of rocks in the basins, and at\r\nleast the upper 6,000 m of rocks in parts of the Los Angeles\r\nBasin central syncline, are dominated by type III/IV OM. In the\r\nLos Angeles Basin, mainstage hydrocarbon (HC) generation\r\ncommences in the type III/IV OM at present-day burial temperatures\r\nof 85\r\n?\r\nto 110\r\n?\r\nC, most likely around 100\r\n?\r\nC, and is largely\r\ncomplete by 220\r\n?\r\nC. In the Southern San Joaquin Valley Basin,\r\nmainstage HC generation commences in type III/IV OM at\r\n150\r\n?\r\nC and is also largely complete by 220\r\n?\r\nC. In the Ventura\r\nBasin, mainstage HC generation commences above 140\r\n?\r\nC in\r\ntype III/IV OM. The apparent lower temperatures for commencement\r\nof HC generation in the Los Angeles Basin are\r\nattributed to the fact that parts of the basin were cooled from\r\nmaximal burial temperatures by increased meteoric water flows\r\nduring the last glaciations.\r\nAll aspects of organic metamorphism, including mainstage\r\nHC generation, are strongly suppressed in rocks with hydrogenrich\r\nOM in these basins. For example, ROCK-EVAL data suggest\r\nthat mainstage HC generation has not commenced in rocks\r\nwith hydrogen-rich OM at present-day temperatures of 198?C.\r\nThis observation is attributed to much stronger bonds in hydrogen-\r\nrich OM compared to types III and IV OM and, therefore,\r\nsignificantly higher burial temperatures are required to break\r\nthese bonds. This difference in OM kinetics has profound ramifications\r\nfor petroleum-geochemical exploration models.\r\nOrganic-matter characteristics inherited from original depositional\r\nconditions were overlaid on, and at times confused\r\ninterpretation of, characteristics from organic metamorphism in\r\nall study areas. In all the basins examined in this study, immature\r\nfine-grained rocks occasionally had high to very high\r\ncarbon-normalized concentrations of pre-generation indigenous\r\nbitumen. This unusual characteristic may be due to unique depositional\r\nconditions in these basins.","language":"ENGLISH","publisher":"U.S. Department of the interior, U.S. Geological Survey,","doi":"10.3133/b2174A","usgsCitation":"Price, L.C., Pawlewicz, M.J., and Daws, T.A., 1999, Organic metamorphism in the California petroleum basins; Chapter A, Rock-Eval and vitrinite reflectance (Version 1.0): U.S. Geological Survey Bulletin 2174, 34 p., https://doi.org/10.3133/b2174A.","productDescription":"34 p.","costCenters":[],"links":[{"id":164591,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3414,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/bul/b2174-a/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae5e4b07f02db68ad7f","contributors":{"authors":[{"text":"Price, Leigh C.","contributorId":39379,"corporation":false,"usgs":true,"family":"Price","given":"Leigh","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":214769,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pawlewicz, Mark J. pawlewicz@usgs.gov","contributorId":752,"corporation":false,"usgs":true,"family":"Pawlewicz","given":"Mark","email":"pawlewicz@usgs.gov","middleInitial":"J.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":214767,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Daws, Ted A.","contributorId":6093,"corporation":false,"usgs":true,"family":"Daws","given":"Ted","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":214768,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":22522,"text":"ofr99384A - 1999 - Geologic datasets for weights-of-evidence analysis in northeast Washington: 2.

The accompanying directory structure contains a Geographic Information Systems (GIS) compilation of geophysical, geological, and tectonic data for the Circum-North Pacific. This area includes the Russian Far East, Alaska, the Canadian Cordillera, linking continental shelves, and adjacent oceans. This GIS compilation extends from 120°E to 115°W, and from 40°N to 80°N. This area encompasses: (1) to the south, the modern Pacific plate boundary of the Japan-Kuril and Aleutian subduction zones, the Queen Charlotte transform fault, and the Cascadia subduction zone; (2) to the north, the continent-ocean transition from the Eurasian and North American continents to the Arctic Ocean; (3) to the west, the diffuse Eurasian-North American plate boundary, including the probable Okhotsk plate; and (4) to the east, the Alaskan-Canadian Cordilleran fold belt. This compilation should be useful for: (1) studying the Mesozoic and Cenozoic collisional and accretionary tectonics that assembled this continental crust of this region; (2) studying the neotectonics of active and passive plate margins in this region; and (3) constructing and interpreting geophysical, geologic, and tectonic models of the region. Geographic Information Systems (GIS) programs provide powerful tools for managing and analyzing spatial databases. Geological applications include regional tectonics, geophysics, mineral and petroleum exploration, resource management, and land-use planning. This CD-ROM contains thematic layers of spatial data-sets for geology, gravity field, magnetic field, oceanic plates, overlap assemblages, seismology (earthquakes), tectonostratigraphic terranes, topography, and volcanoes. The GIS compilation can be viewed, manipulated, and plotted with commercial software (ArcView and ArcInfo) or through a freeware program (ArcExplorer) that can be downloaded from http://www.esri.com for both Unix and Windows computers using the button below.

Metal-mining related wastes in the Boulder River basin study area in northern Jefferson County, Montana have been implicated in their detrimental effects on water quality with regard to acid-generation and toxic-metal solubilization. Flotation-mill tailings in the meadow below the Buckeye mine, hereafter referred to as the Buckeye mill-tailings site, have been identified as significant contributors to water quality degradation of Basin Creek, Montana. Basin Creek is one of three tributaries to the Boulder River in the study area; bed sediments and waters draining from the Buckeye mine have also been implicated. Geochemical analysis of 35 tailings cores and six bed-sediment samples was undertaken to determine the concentrations of Ag, As, Cd, Cu, Pb,and Zn present in these materials. These elements are environmentally significant, in that they can be toxic to fish and/or the invertebrate organisms that constitute their food. A suite of one-inch cores of dispersed flotation-mill tailings and underlying premining material was taken from a large, flat area north of Basin Creek near the site of the Buckeye mine. Thirty-five core samples were taken and divided into 204 subsamples. The samples were analyzed by ICP-AES (inductively coupled plasma-atomic emission spectroscopy) using a mixed-acid digestion. Results of the core analyses show that the elements listed above are present at moderate to very high concentrations (arsenic to 63,000 ppm, silver to 290 ppm, cadmium to 370 ppm, copper to 4,800 ppm, lead to 93,000 ppm, and zinc to 23,000 ppm). Volume calculations indicate that an estimated 8,400 metric tons of contaminated material are present at the site. Six bed-sediment samples were also subjected to the mixed-acid total digestion, and a warm (50°C) 2M HCl-1% H2O2 leach and analyzed by ICP-AES. Results indicate that bed sediments of Basin Creek are only slightly impacted by past mining above the Buckeye-Enterprise complex, moderately impacted at the upper (eastern) end of the tailings area, and heavily impacted at the lower (western) end of the area and downstream. The metals are mostly contained in the 2M HCl-1% H2O2 leachable phase, which are the hydrous amorphous iron- and manganese-hydroxide coatings on detrital sediment particles.

Selected samples of modern dust collected in marble traps at sites in southern Nevada and California (Reheis and Kihl, 1995; Reheis, 1997) have been analyzed for elemental composition using instrumental neutron activation analysis (INAA) and inductively coupled plasma atomic emission spectroscopy (ICP-AES) and inductively coupled plasma mass spectroscopy (ICP-MS). For information on these analytical techniques and their levels of precision and accuracy, refer to Baedecker and McKown (1987) for INAA, to Briggs (1996) for ICP-AES, and to Briggs and Meier (1999) for ICP-MS. This report presents the elemental compositions obtained using these techniques on dust samples collected from 1991 through 1997.

The dust-trap sites were established at varying times; some have been maintained since 1984, others since 1991. For details on site location, dust-trap construction, and collection techniques, see Reheis and Kihl (1995) and Reheis (1997). Briefly, the trap consists of a coated angel-food cake pan painted black on the outside and mounted on a post about 2 m above the ground. Glass marbles rest on a circular piece of galvanized hardware cloth (now replaced by stainless-steel mesh), which is fitted into the pan so that it rests 3-4 cm below the rim. The 2-m height eliminates most saltating sand-sized particles. The marbles simulate the effect of a gravelly fan surface and prevent dust that has filtered or washed into the bottom of the pan from being blown back out. The dust traps are fitted with two metal straps looped in an inverted basket shape; the top surfaces of the straps are coated with a sticky material that effectively discourages birds from roosting.

We have approached this\r\nproblem in the Animas River watershed using geomorphologic mapping methods to\r\nidentify old pre-mining sediments. A systematic evaluation of possible sites resulted in\r\ncollection of a large number of samples of pre-mining sediments, overbank sediments,\r\nand fluvial tailings deposits from more than 50 sites throughout the watershed. Chemical\r\nanalysis of individual stratigraphic layers has resulted in a chemical stratigraphy that can\r\nbe tied to the historical record through geochronological and dendochronological studies\r\nat these sites.\r\nPreliminary analysis of geochemical data from more than 500 samples from this\r\nstudy, when coupled with both the historical and geochronological record, clearly show\r\nthat there has been a major impact by historical mining activities on the geochemical\r\nrecord preserved in these fluvial bed sediments. Historical mining activity has resulted in\r\na substantial increase in metals in the very fine sand to clay sized component of the bed\r\nsediment of the upper Animas River, and Cement and Mineral Creeks. Enrichment\r\nfactors for metals in modern bed sediments, relative to the pre-mining sediments, range\r\nfrom a factor of 2 to 6 for arsenic, 4 to more than 10 for cadmium, 2 to more than 10 for\r\nlead, 2 to 5 for silver, and 2 to more than 15 for zinc. However, the pre-mining bed\r\nsediment geochemical baseline is high relative to crustal abundance levels of many orerelated\r\nmetals and the watershed would readily be identified as a highly mineralized area\r\nsuitable for mineral exploration if it had not been disturbed by historical mining activity.\r\nWe infer from these data that the water chemistry in the streams was less acidic prior to\r\nhistorical mining activity in the watershed.\r\nPaleoentologic evidence does not indicate a healthy aquatic habitat in any of the\r\nstream reaches investigated above the confluence of the Animas River with Mineral\r\nCreek (fig. 1) prior to the impact of historical mining activity. The absence of\r\npaleoentologic remains is interpreted to reflect the poor preservation regime of the bed\r\nsediment materials sampled. The fluvial sediments sampled in this study represent higher\r\nenergy environments than are conducive to the preservation of most aquatic organisms\r\nincluding fish remains.

Mount Jefferson (one of thirteen major volcanic centers in the Cascade Range) has erupted repeatedly for hundreds of thousands of years, with its last eruptive episode during the last major glaciation which culminated about 15,000 years ago. Geologic evidence shows that Mount Jefferson is capable of large explosive eruptions. The largest such eruption occurred between 35,000 and 100,000 years ago, and caused ash to fall as far away as the present-day town of Arco in southeast Idaho. Although there has not been an eruption at Mount Jefferson for some time, experience at explosive volcanoes elsewhere suggests that Mount Jefferson cannot be regarded as extinct. If Mount Jefferson erupts again, areas close to the eruptive vent will be severely affected, and even areas tens of kilometers (tens of miles) downstream along river valleys or hundreds of kilometers (hundreds of miles) downwind may be at risk. Numerous small volcanoes occupy the area between Mount Jefferson and Mount Hood to the north, and between Mount Jefferson and the Three Sisters region to the south. These small volcanoes tend not to pose the far-reaching hazards associated with Mount Jefferson, but are nonetheless locally important. A concern at Mount Jefferson, but not at the smaller volcanoes, is the possibility that small to- moderate sized landslides could occur even during periods of no volcanic activity. Such landslides may transform as they move into lahars (watery flows of rock, mud, and debris) that can inundate areas far downstream. The population at immediate risk in the Mount Jefferson region is small, but these residents as well as other people who visit the area for recreation and work purposes should be aware of the potential hazards. Probably the greatest concern in the Mount Jefferson region is the possibility that large lahars might enter reservoirs on either side of the volcano, namely, Detroit Lake to the west and Lake Billy Chinook to the east. Lahars entering these lakes could set up large waves that could overtop dams and possibly cause dam failure, with catastrophic effects downstream. Such events have very low probabilities but great potential consequences. This report describes the kinds of hazardous geologic events that have occurred in the Mount Jefferson area in the past and shows, in the accompanying volcano-hazards-zonation maps, which areas will likely be at risk when hazardous events occur again in the future.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr9924","issn":"0094-9140","usgsCitation":"Walder, J.S., Gardner, C.A., Conrey, R.M., Fisher, B.J., and Schilling, S.P., 1999, Volcano hazards in the Mount Jefferson region, Oregon: U.S. Geological Survey Open-File Report 99-24, Report: 14 p.; 2 Plates: 38 x 27 inches and 29.24 x 31.08 inches, https://doi.org/10.3133/ofr9924.","productDescription":"Report: 14 p.; 2 Plates: 38 x 27 inches and 29.24 x 31.08 inches","numberOfPages":"18","additionalOnlineFiles":"Y","costCenters":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":279257,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr9924.jpg"},{"id":1336,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0024/","linkFileType":{"id":5,"text":"html"}},{"id":51681,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1999/0024/pdf/of1999-0024_plate1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51682,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1999/0024/pdf/of1999-0024_plate2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":51683,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0024/pdf/of1999-0024.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"100000","projection":"Universal Transverse Mercator projection","datum":"1927 North American Datum","country":"United States","state":"Oregon","otherGeospatial":"Cascade Range;Detroit Lake;Lake Billy Chinook;Mount Jefferson","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.65,39.85 ], [ -124.65,49.05 ], [ -116.41,49.05 ], [ -116.41,39.85 ], [ -124.65,39.85 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd7a8","contributors":{"authors":[{"text":"Walder, Joseph S. jswalder@usgs.gov","contributorId":2046,"corporation":false,"usgs":true,"family":"Walder","given":"Joseph","email":"jswalder@usgs.gov","middleInitial":"S.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":187809,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gardner, Cynthia A. 0000-0002-6214-6182 cgardner@usgs.gov","orcid":"https://orcid.org/0000-0002-6214-6182","contributorId":1959,"corporation":false,"usgs":true,"family":"Gardner","given":"Cynthia","email":"cgardner@usgs.gov","middleInitial":"A.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":187808,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Conrey, Richard M.","contributorId":41911,"corporation":false,"usgs":true,"family":"Conrey","given":"Richard","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":187812,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fisher, Bruce J.","contributorId":40293,"corporation":false,"usgs":true,"family":"Fisher","given":"Bruce","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":187811,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schilling, Steven P.","contributorId":31081,"corporation":false,"usgs":true,"family":"Schilling","given":"Steven","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":187810,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}} ,{"id":60292,"text":"mf2330 - 1999 - Bituminous coal production in the Appalachian Basin: Past, present, and future","interactions":[],"lastModifiedDate":"2022-10-12T20:42:01.657828","indexId":"mf2330","displayToPublicDate":"2000-03-01T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":325,"text":"Miscellaneous Field Studies Map","code":"MF","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"2330","title":"Bituminous coal production in the Appalachian Basin: Past, present, and future","docAbstract":"This report on Appalachian basin coal production consists of four maps and associated graphs and tables, with links to the basic data that were used to construct the maps.

Plate 2 shows the amount of coal produced (tons) during the year of maximum coal production for each county. Plate 3 illustrates the cumulative coal production (tons) for each county since about the beginning of the 20th century. Plate 4 shows 1996 annual production by county. During the current (third) cycle of coal production in the Appalachian basin, only seven major coal-producing counties (those with more than 500 million tons cumulative production), including Greene County, Pa.; Boone, Kanawha, Logan, Mingo, and Monongalia Counties, W.Va.; and Pike County, Ky., exhibit a general increase in coal production. Other major coal-producing counties have either declined to a small percentage of their maximum production or are annually maintaining a moderate level of production. In general, the areas with current high coal production have large blocks of coal that are suitable for mining underground with highly efficient longwall methods, or are occupied by very large scale, relatively low cost surface mining operations. The estimated cumulative production for combined bituminous and anthracite coal is about 100 billion tons or less for the Appalachian basin. In general, it is anticipated that the remaining resources will be progressively of lower quality, will cost more to mine, and will become economical only as new technologies for extraction, beneficiation, and consumption are developed, and then only if prices for coal increase.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/mf2330","usgsCitation":"Milici, R.C., 1999, Bituminous coal production in the Appalachian Basin: Past, present, and future (Online version 1.0): U.S. Geological Survey Miscellaneous Field Studies Map 2330, HTML Document, https://doi.org/10.3133/mf2330.","productDescription":"HTML Document","costCenters":[],"links":[{"id":109906,"rank":700,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_23427.htm","linkFileType":{"id":5,"text":"html"},"description":"23427"},{"id":6022,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/mf-maps/mf-2330/","linkFileType":{"id":5,"text":"html"}},{"id":183603,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"scale":"250000","country":"United States","otherGeospatial":"Appalachian Basin","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -88.333,\n 32.633\n ],\n [\n -76.867,\n 32.633\n ],\n [\n -76.867,\n 41.817\n ],\n [\n -88.333,\n 41.817\n ],\n [\n -88.333,\n 32.633\n ]\n ]\n ]\n }\n }\n ]\n}","edition":"Online version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e5e4b07f02db5e6fed","contributors":{"authors":[{"text":"Milici, R.

The San Francisco Bay region sits astride a dangerous “earthquake machine,” the tectonic boundary between the Pacific and North American Plates. The region has experienced major and destructive earthquakes in 1838, 1868, 1906, and 1989, and future large earthquakes are a certainty. The ability to prepare for large earthquakes is critical to saving lives and reducing damage to property and infrastructure. An increased understanding of the timing, size, location, and effects of these likely earthquakes is a necessary component in any effective program of preparedness.

This study reports on the probabilities of occurrence of major earthquakes in the San Francisco Bay region (SFBR) for the three decades 2000 to 2030. The SFBR extends from Healdsberg on the northwest to Salinas on the southeast and encloses the entire metropolitan area, including its most rapidly expanding urban and suburban areas. In this study a “major” earthquake is defined as one with M≥6.7 (where M is moment magnitude). As experience from the Northridge, California (M6.7, 1994) and Kobe, Japan (M6.9, 1995) earthquakes has shown us, earthquakes of this size can have a disastrous impact on the social and economic fabric of densely urbanized areas.

\n
\n

To reevaluate the probability of large earthquakes striking the SFBR, the U.S. Geological Survey solicited data, interpretations, and analyses from dozens of scientists representing a wide crosssection of the Earth-science community (Appendix A). The primary approach of this new Working Group (WG99) was to develop a comprehensive, regional model for the long-term occurrence of earthquakes, founded on geologic and geophysical observations and constrained by plate tectonics. The model considers a broad range of observations and their possible interpretations. Using this model, we estimate the rates of occurrence of earthquakes and 30-year earthquake probabilities. Our study considers a range of magnitudes for earthquakes on the major faults in the region—an innovation over previous studies of the SFBR that considered only a small number of potential earthquakes of fixed magnitude.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99517","usgsCitation":"Working Group on California Earthquake Probabilities, 1999, Earthquake probabilities in the San Francisco Bay region: 2000 to 2030 - A summary of findings (Online version 1.0.): U.S. Geological Survey Open-File Report 99-517, 36 p., https://doi.org/10.3133/ofr99517.","productDescription":"36 p.","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":154694,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr99517.jpg"},{"id":1193,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0517/","linkFileType":{"id":5,"text":"html"}},{"id":407087,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_23006.htm","linkFileType":{"id":5,"text":"html"}},{"id":285025,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0517/pdf/of99-517.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay region","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -123.25,\n 36.5\n ],\n [\n -121.667,\n 36.5\n ],\n [\n -121.667,\n 38.667\n ],\n [\n -123.25,\n 38.667\n ],\n [\n -123.25,\n 36.5\n ]\n ]\n ]\n }\n }\n ]\n}","edition":"Online version 1.0.","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a51e4b07f02db62978a","contributors":{"authors":[{"text":"Working Group on California Earthquake Probabilities","contributorId":127922,"corporation":true,"usgs":false,"organization":"Working Group on California Earthquake Probabilities","id":529073,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70170451,"text":"70170451 - 1999 - Predicting mountain lion activity using radiocollars equipped with mercury tip-sensors","interactions":[],"lastModifiedDate":"2016-04-20T17:15:04","indexId":"70170451","displayToPublicDate":"2000-02-01T05:15:00","publicationYear":"1999","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3779,"text":"Wildlife Society Bulletin","onlineIssn":"1938-5463","printIssn":"0091-7648","active":true,"publicationSubtype":{"id":10}},"title":"Predicting mountain lion activity using radiocollars equipped with mercury tip-sensors","docAbstract":"

Radiotelemetry collars with tip-sensors have long been used to monitor wildlife activity. However, comparatively few researchers have tested the reliability of the technique on the species being studied. To evaluate the efficacy of using tip-sensors to assess mountain lion (Puma concolor) activity, we radiocollared 2 hand-reared mountain lions and simultaneously recorded their behavior and the associated telemetry signal characteristics. We noted both the number of pulse-rate changes and the percentage of time the transmitter emitted a fast pulse rate (i.e., head up) within sampling intervals ranging from 1-5 minutes. Based on 27 hours of observations, we were able to correctly distinguish between active and inactive behaviors >93% of the time using a logistic regression model. We present several models to predict activity of mountain lions; the selection of which to us would depend on study objectives and logistics. Our results indicate that field protocols that use only pulse-rate changes to indicate activity can lead to significant classification errors.

This report describes enhancements to a Graphical-User Interface (GUI) for MODFLOW-96, the U.S. Geological Survey (USGS) modular, three-dimensional, finitedifference ground-water flow model, and MOC3D, the USGS three-dimensional, method-ofcharacteristics solute-transport model. The GUI is a plug-in extension (PIE) for the commercial program Argus ONEe. The GUI has been modified to support MODPATH (a particle tracking post-processing package for MODFLOW), ZONEBDGT (a computer program for calculating subregional water budgets), and the Stream, Horizontal-Flow Barrier, and Flow and Head Boundary packages in MODFLOW. Context-sensitive help has been added to make the GUI easier to use and to understand. In large part, the help consists of quotations from the relevant sections of this report and its predecessors. The revised interface includes automatic creation of geospatial information layers required for the added programs and packages, and menus and dialog boxes for input of parameters for simulation control. The GUI creates formatted ASCII files that can be read by MODFLOW-96, MOC3D, MODPATH, and ZONEBDGT. All four programs can be executed within the Argus ONEe application (Argus Interware, Inc., 1997). Spatial results of MODFLOW-96, MOC3D, and MODPATH can be visualized within Argus ONEe. Results from ZONEBDGT can be visualized in an independent program that can also be used to view budget data from MODFLOW, MOC3D, and SUTRA. Another independent program extracts hydrographs of head or drawdown at individual cells from formatted MODFLOW head and drawdown files. A web-based tutorial on the use of MODFLOW with Argus ONE has also been updated. The internal structure of the GUI has been modified to make it possible for advanced users to easily customize the GUI.

The digital geologic and geographic information system (GIS) data presented here were prepared to aid in Grand Mesa, Uncompahgre, Gunnison National Forest (GMUG) mineral resource assessment Project studies by the U.S. Geological Survey Mineral Resource Program. The goals of the GMUG Project is to provide mineral resource data and an assessment for undiscovered mineral resources in U.S. Forest Service (USFS) and Bureau of Land Management (BLM) lands in southwestern Colorado. The Project area covers a large region in southwestern Colorado that is bounded by latitudes 37o 45’ to 39o 30’ north and longitudes 106o to 109o west. The study area is covered by all or parts of six 1o x2o topographic and quadrangle geologic maps, which include geologic maps for the Leadville (Tweto and others, 1978), Montrose (Tweto and others, 1976), Durango (Steven and others, 1974), Grand Junction (Cashion, 1973), Moab (Williams, 1976), and Cortez (Haynes and others, 1972) quadrangles. These geologic maps were used inasmuch as a complete remapping and compilation effort for this study area was beyond the scope of the Project.

Therefore, it is likely that many economically viable and strategically significant conventional undiscovered mineral deposits will be found in bedrock concealed beneath basin sediments. Mineral resource assessments must incorporate an understanding of the geometry, structure, and concealed lithology of basins in order to be accurate. This report presents an analysis of the basin geometry and structure of the San Rafael basin in southeastern Arizona. In addition, a new methodology for inferring concealed lithology is presented and applied in the San Rafael basin.\n\nGravity data is used to model the geometry of the basin using recent models of sediment density vs. depth developed in the region. This modeling indicates that the basin has a maximum depth of approximately 1.05 km plus or minus 0.10 km. In the southern portion, the basin can be modeled as an asymmetric graben faulted on the western margin. The northern portion of the basin is structurally more complex and may have high angle faults on the western, northern, and eastern margin. Near-ground closely spaced Earth’s total intensity magnetic field data is used to locate concealed faults within the basin. This data is also used to infer lithology concealed by shallow basin sediments. Airborne Earth’s total intensity magnetic field data is used to help infer concealed lithology in deep portions of the basin. The product of integrating all data and interpretations is a map which presents the geometry of the basin, faults and contacts concealed by basin sediments, and an estimate of the bedrock lithology concealed by basin sediment.\n\nBased on basin geometry and concealed lithology, the San Rafael basin has a high potential for concealed mineral deposits on its western and northern margin. In particular, a newly discovered magnetic anomaly in the northern portion of the basin can be modeled as a granitic intrusion with highly altered margins and may represent a potential mineral resource target. Based on the permeability and porosity of upper basin fill found in nearby basins, the San Rafael basin may contain an aquifer up to 300 meters thick over a substantial area of the basin.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99399","issn":"0094-9140","usgsCitation":"Bultman, M.W., 1999, Geometry, structure, and concealed lithology of the San Rafael Basin, southeastern Arizona (Version 1.0): U.S. Geological Survey Open-File Report 99-399, HTML document, https://doi.org/10.3133/ofr99399.","productDescription":"HTML document","onlineOnly":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":155840,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr99399.jpg"},{"id":284960,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0399/intro.html"},{"id":1370,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0399/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Arizona","otherGeospatial":"San Rafael Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.25,31.5 ], [ -111.25,32.0 ], [ -110.25,32.0 ], [ -110.25,31.5 ], [ -111.25,31.5 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5e9be4b0b290850fbcd8","contributors":{"authors":[{"text":"Bultman, Mark W. 0000-0001-8352-101X mbultman@usgs.gov","orcid":"https://orcid.org/0000-0001-8352-101X","contributorId":3348,"corporation":false,"usgs":true,"family":"Bultman","given":"Mark","email":"mbultman@usgs.gov","middleInitial":"W.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":false,"id":188556,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":21896,"text":"ofr9949 - 1999 - Inversion of gravity data to define the pre-Tertiary surface and regional structures possibly influencing ground-water flow in the Pahute Mesa-Oasis Valley region, Nye County, Nevada","interactions":[],"lastModifiedDate":"2023-06-15T15:57:02.418827","indexId":"ofr9949","displayToPublicDate":"2000-01-10T00:00:00","publicationYear":"1999","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"99-49","title":"Inversion of gravity data to define the pre-Tertiary surface and regional structures possibly influencing ground-water flow in the Pahute Mesa-Oasis Valley region, Nye County, Nevada","docAbstract":"A three-dimensional inversion of gravity data from the Pahute Mesa–Oasis Valley region reveals a topographically complex pre-Tertiary basement surface. Beneath Pahute Mesa, the thickness of the Tertiary volcanic deposits may exceed 5 km within the Silent Canyon caldera complex. South of Pahute Mesa in Oasis Valley, basement is shallower (< 1 km) but between this valley and the Timber Mountain caldera complex is a basin that probably represents, in part, a moat related to the Timber Mountain caldera complex. Of particular interest is a NE-trending lineament, named here the Thirsty Canyon lineament (TCL), separating terranes at significantly different elevations. Southeast of the TCL, a highly undulating basement surface descends deeply into several calderas, whereas NW of the TCL basement is relatively flat and shallow. Because as many as four calderas seem to abruptly terminate at the TCL, the TCL may reflect a major buried fault zone, which influenced caldera growth. This inferred Thirsty Canyon fault zone and several EW basement ridges in the derived 3-dimensional basin thickness model may influence the flow of ground water from the Pahute Mesa region to Oasis Valley.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr9949","collaboration":"Prepared in cooperation with the U.S. Department of Energy Nevada Operations Office (Interagency Agreement DE-AI08-96NV11967)","usgsCitation":"Hildenbrand, T., Langenheim, V., Mankinen, E., and McKee, E., 1999, Inversion of gravity data to define the pre-Tertiary surface and regional structures possibly influencing ground-water flow in the Pahute Mesa-Oasis Valley region, Nye County, Nevada (Version 1.0): U.S. Geological Survey Open-File Report 99-49, 26 p., https://doi.org/10.3133/ofr9949.","productDescription":"26 p.","numberOfPages":"29","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":155422,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr9949.gif"},{"id":1263,"rank":4,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0049/","linkFileType":{"id":5,"text":"html"}},{"id":284837,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0049/pdf/of99-49.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":405811,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_22749.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Nevada","county":"Nye County","otherGeospatial":"Pahute Mesa-Oasis Valley region","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -116.833,\n 36.917\n ],\n [\n -116.25,\n 36.917\n ],\n [\n -116.25,\n 37.333\n ],\n [\n -116.833,\n 37.333\n ],\n [\n -116.833,\n 36.917\n ]\n ]\n ]\n }\n }\n ]\n}","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd630ae4b0b290850fe915","contributors":{"authors":[{"text":"Hildenbrand, T.G.","contributorId":83892,"corporation":false,"usgs":true,"family":"Hildenbrand","given":"T.G.","email":"","affiliations":[],"preferred":false,"id":186156,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Langenheim, V.E. 0000-0003-2170-5213","orcid":"https://orcid.org/0000-0003-2170-5213","contributorId":54956,"corporation":false,"usgs":true,"family":"Langenheim","given":"V.E.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":false,"id":186155,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mankinen, E.
