The study is intended to provide land-use planners and managers, particularly in the Bureau of Land Management, with a foundation of knowledge that will allow them to anticipate and plan for demand for and development of sand and gravel resources on public lands in response to the urban growth. Attributes under study include: regional geology of both alluvial source areas as well as deposits; fluvial processes that led to deposition of the sand and gravel deposits; spatial distribution of the deposits; quantity and quality of materials in the deposits; and the suitability of the deposits for a range of applications. The study will also examine and attempt to model the association between fluvial processes, deposit characteristics, and physical specifications for various applications of sand and gravel. The results will be presented in a series of sand and gravel assessment reports of which this is the first.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01130","usgsCitation":"Bliss, J.D., and Moyle, P.R., 2001, Assessment of the sand and gravel resources of the Lower Boise River Valley area, Idaho: Part one: Geological framework of the sand and gravel deposits: U.S. Geological Survey Open-File Report 2001-130, Report: 41 p., Readme, https://doi.org/10.3133/ofr01130.","productDescription":"Report: 41 p., Readme","numberOfPages":"41","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":160836,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr01130.jpg"},{"id":282078,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0130/pdf/of01-130.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":3028,"rank":4,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0130/","linkFileType":{"id":5,"text":"html"}},{"id":282079,"rank":2,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2001/0130/readme.doc"},{"id":410562,"rank":5,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_43368.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Idaho","otherGeospatial":"Boise River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117,\n              43.417\n            ],\n            [\n              -117,\n              43.917\n            ],\n            [\n              -116,\n              43.917\n            ],\n            [\n              -116,\n              43.417\n            ],\n            [\n              -117,\n              43.417\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abae4b07f02db671cff","contributors":{"authors":[{"text":"Bliss, James D. jbliss@usgs.gov","contributorId":2790,"corporation":false,"usgs":true,"family":"Bliss","given":"James","email":"jbliss@usgs.gov","middleInitial":"D.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":205798,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moyle, Phillip R.","contributorId":100898,"corporation":false,"usgs":true,"family":"Moyle","given":"Phillip","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":205799,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In addition to landslides, heavy rainfall caused flooding and massive debris flows that damaged coastal communities in the State of Vargas along the Caribbean Sea. Examination of the rainfall pattern obtained from the GOES-8 satellite showed that the pattern of damage was generally consistent with the area of heaviest rainfall. Field observations of the severely affected drainage basins and historical records indicate that previous flooding and massive debris-flow events of similar magnitude to that of December 1999 have occurred throughout this region. The volume of debris-flow deposits and the large boulders that the flows transported qualifies the 1999 event amongst the largest historical rainfall-induced debris flows documented worldwide.","language":"ENGLISH","doi":"10.3133/ofr01144","usgsCitation":"Wieczorek, G.F., Larsen, M.C., Eaton, L., Morgan, B., and Blair, J., 2001, Debris-flow and flooding hazards associated with the December 1999 storm in coastal Venezuela and strategies for mitigation: U.S. Geological Survey Open-File Report 2001-144, 24 figs., https://doi.org/10.3133/ofr01144.","productDescription":"24 figs.","costCenters":[],"links":[{"id":160853,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3032,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr-01-0144/ ","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abbe4b07f02db67279c","contributors":{"authors":[{"text":"Wieczorek, G.

The data for this publication total 557 MB on the CD-ROM. For speed of transfer, the main PDF document has been compressed (with a subsequent loss of image quality) from 145 to 18.1 MB.  The community of Forest Falls, California, is frequently subject to relatively slow moving debris flows. Some 11 debris flow events that were destructive to property have been recorded between 1955 and 1998. On July 11 and 13, 1999, debris flows again occurred, produced by high-intensity, short-duration monsoon rains. Unlike previous debris flow events, the July 11 rainfall generated a high-velocity debris avalanche in Snow Creek, one of the several creeks crossing the composite, debris flow dominated, alluvial fan on which Forest Falls is located. This debris avalanche overshot the bank of the active debris flow channel of Snow Creek, destroying property in the near vicinity and taking a life. The minimum velocity of this avalanche is calculated to have been in the range of 40 to 55 miles per hour. Impact from high-velocity boulders removed trees where the avalanche overshot the channel bank. Further down the fan, the rapidly moving debris fragmented the outer parts of the upslope side of large pine trees and embedded rock fragments into the tree trunks. Unlike the characteristic deposits formed by debris flows, the avalanche spread out down-slope and left no deposit suggestive of a debris avalanche. This summer monsoon-generated debris avalanche is apparently the first recorded for Forest Falls. The best indications of past debris avalanches may be the degree of permanent scars produced by extensive abrasion and splintering of the outer parts of pine trees that were in the path of an avalanche.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr01146","usgsCitation":"Morton, D.M., and Hauser, R.M., 2001, A debris avalanche at Forest Falls, San Bernardino County, California, July 11, 1999: U.S. Geological Survey Open-File Report 2001-146, Readme TXT; Report: 67 p.; Illustrations HTML link, https://doi.org/10.3133/ofr01146.","productDescription":"Readme TXT; Report: 67 p.; Illustrations HTML link","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":335858,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":282425,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0146/README.TXT"},{"id":282424,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0146/"},{"id":282426,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0146/pdf/of01-146.pdf"},{"id":282427,"type":{"id":14,"text":"Image"},"url":"https://pubs.usgs.gov/of/2001/0146/illustrations.htm"}],"country":"United States","state":"California","county":"San Bernardino County","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b25e4b07f02db6af2ee","contributors":{"authors":[{"text":"Morton, Douglas M. scamp@usgs.gov","contributorId":4102,"corporation":false,"usgs":true,"family":"Morton","given":"Douglas","email":"scamp@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":true,"id":511072,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hauser, Rachel M.","contributorId":86010,"corporation":false,"usgs":true,"family":"Hauser","given":"Rachel","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":511073,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The map was produced digitally by classifying geologic-map units according to composition, mineralogy, and texture; rather than by age and stratigraphic relationships as shown on traditional geologic maps. This map differs from most lithologic maps in that the lithogeochemical unit classification distinguishes those rock units having key water-reactive minerals that may induce acid neutralization, or reduction, of hosted water at the weathering interface. The validity of these rock units, however, is independent of water chemistry, because the rock units are derived from geologic maps and rock descriptions. Areas of high soil carbon content, and sulfide metal deposits are also shown. \r\nWater-reactive minerals and their weathering reactions yield five lithogeochemical unit classes: 1) carbonate rock and calcareous rocks and sediments, the most acid-neutralizing; 2)carbonaceous-sulfidic rocks and sediments, oxygen-depleting and reducing; 3) quartzofeldspathic rocks and siliciclastic sediments, relatively weakly reactive with water; 4) mafic silicate rocks/sediments, oxygen consuming and high solute-load delivering; and, 5) the rarer calcareous-sulfidic (carbonaceous) rocks, neutralizing and reducing. Earlier studies in some parts of the map area have related solute loads in ground and stream waters to some aspects of bedrock lithology. More recent preliminary tests of relationships between four of the classes of mapped lithogeochemical units and ground water chemistry, in the Mid-Atlantic area using this map, have focused on and verified the nitrate-reducing and acid-neutralizing properties of some bedrock and unconsolidated aquifer rock types. Sulfide mineral deposits and their mine-tailings effects on waters are beginning to be studied by others. Additional testing of relationships among the lithogeochemical units and aspects of ground and surface water chemistry could help to refine the lithogeochemical classification, and this map. The testing could also improve the usefulness of the map for assessing aquifer reactivity and the transport properties of reactive contaminants such as acid rain, and nitrate from agricultural sources, in the Chesapeake Bay watershed.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01187","usgsCitation":"Peper, J.D., McCartan, L., Horton, J., and Reddy, J.E., 2001, Preliminary lithogeochemical map showing near-surface rock types in the Chesapeake Bay watershed, Virginia and Maryland: U.S. Geological Survey Open-File Report 2001-187, Report: 26 p.; 1 Plate: 48.00 × 32.00 inches; Read Me; Data Downloads, https://doi.org/10.3133/ofr01187.","productDescription":"Report: 26 p.; 1 Plate: 48.00 × 32.00 inches; Read Me; Data Downloads","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":164192,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":110231,"rank":700,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_45594.htm","linkFileType":{"id":5,"text":"html"},"description":"45594"},{"id":3057,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/openfile/of01-187/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maryland, Virginia","otherGeospatial":"Chesapeake Bay watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -79.595947265625,\n              36.38591277287651\n            ],\n            [\n              -75.76171875,\n              36.38591277287651\n            ],\n            [\n              -75.76171875,\n              39.740986355883564\n            ],\n            [\n              -79.595947265625,\n              39.740986355883564\n            ],\n            [\n              -79.595947265625,\n              36.38591277287651\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abde4b07f02db6742d8","contributors":{"authors":[{"text":"Peper, John D.","contributorId":105320,"corporation":false,"usgs":true,"family":"Peper","given":"John","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":205838,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McCartan, Lucy","contributorId":20801,"corporation":false,"usgs":true,"family":"McCartan","given":"Lucy","email":"","affiliations":[],"preferred":false,"id":205837,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Horton, J.

This study evaluates two simple tools for estimating the economic viability of porphyry copper deposits mined by open-pit, heap-leach methods when only limited information on these deposits is available. These two methods are useful for evaluating deposits that either (1) are undiscovered deposits predicted by a mineral resource assessment, or (2) have been discovered but for which little data has been collected or released. The first tool uses ordinary least-squared regression analysis of cost and operating data from selected deposits to estimate a predictive relationship between mining rate, itself estimated from deposit size, and capital and operating costs. The second method uses cost models developed by the U.S. Bureau of Mines (Camm, 1991) updated using appropriate cost indices. We find that the cost model method works best for estimating capital costs and the empirical model works best for estimating operating costs for mines to be developed in the United States.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr01218","usgsCitation":"Long, K.R., and Singer, D.A., 2001, A simplified economic filter for open-pit mining and

Geological Survey modular finite-difference ground-water flow model (MODFLOW)","docAbstract":"The Variable-Recharge Package is a\r\ncomputerized method designed for use with the\r\nU.S. Geological Survey three-dimensional finitedifference\r\nground-water flow model\r\n(MODFLOW-88) to simulate areal recharge to an\r\naquifer. It is suitable for simulations of aquifers in\r\nwhich the relation between ground-water levels\r\nand land surface can affect the amount and\r\ndistribution of recharge. The method is based on\r\nthe premise that recharge to an aquifer cannot\r\noccur where the water level is at or above land\r\nsurface. Consequently, recharge will vary\r\nspatially in simulations in which the Variable-\r\nRecharge Package is applied, if the water levels\r\nare sufficiently high. The input data required by\r\nthe program for each model cell that can\r\npotentially receive recharge includes the average\r\nland-surface elevation and a quantity termed\r\n?water available for recharge,? which is equal to\r\nprecipitation minus evapotranspiration.\r\nThe Variable-Recharge Package also can\r\nbe used to simulate recharge to a valley-fill\r\naquifer in which the valley fill and the adjoining\r\nuplands are explicitly simulated. Valley-fill\r\naquifers, which are the most common type of\r\naquifer in the glaciated northeastern United\r\nStates, receive much of their recharge from\r\nupland sources as channeled and(or) unchanneled\r\nsurface runoff and as lateral ground-water flow.\r\nSurface runoff in the uplands is generated in the\r\nmodel when the applied water available for\r\nrecharge is rejected because simulated water\r\nlevels are at or above land surface. The surface\r\nrunoff can be distributed to other parts of the\r\nmodel by (1) applying the amount of the surface\r\nrunoff that flows to upland streams (channeled\r\nrunoff) to explicitly simulated streams that flow\r\nonto the valley floor, and(or) (2) applying the\r\namount that flows downslope toward the valley-\r\nfill aquifer (unchanneled runoff) to specified\r\nmodel cells, typically those near the valley wall.\r\nAn example model of an idealized valley-\r\nfill aquifer is presented to demonstrate application\r\nof the method and the type of information that can\r\nbe derived from its use. Documentation of the\r\nVariable-Recharge Package is provided in the\r\nappendixes and includes listings of model code\r\nand of program variables. Comment statements in\r\nthe program listings provide a narrative of the\r\ncode.

These horizons stratigraphically and temporally bracket thrust emplacement of a major allochthonous thrust plate of mainly quartzarenite of the Ordovician Vinini Formation. Lithologic and shape-ratio data from approximately 4,200 pebbles and cobbles at 17 sites as well as biostratigraphic data in the Strathearn, and their geologic implications, are included in this report. Conodont biofacies throughout the Strathearn Formation are normal marine and suggest middle shelf or deeper depositional environments. The conglomerate units roughly are similar in that they contain only chert and quartzarenite pebbles, but they differ in compositional proportions of the two lithologies. The relative proportion of quartzarenite pebbles increases sixfold in the middle Lower Permian upper conglomerate unit versus its content in the middle Upper Pennsylvanian lower unit, whereas chert pebbles predominate in both units. Various roundness categories of chert pebbles in both conglomerate units of the Strathearn show that the equant pebble class (B/A) = 1 clearly is represented strongly even in the subangular category, the lowest roundness categories for the pebbles. Thus, development of equant pebbles cannot be ascribed totally to a rounding process during predeposition transport. The equant character of many pebbles might, in part, be an original feature inherited from pre-erosion rock fractures and (or) bedding that control overall form of the fragments prior to their release to the transport environment. The allochthon of the Coyote thrust has been thrust above the lower conglomerate unit of the Strathearn during a regionally extensive contractional event in the late Paleozoic. The middle Lower Permian upper conglomerate unit, highest unit recognized in the Strathearn Formation, as well as similarly-aged dolomitic siltstone, onlap directly onto quartzarenite that comprises the allochthon of the Coyote thrust. The conglomerate units thus represent submarine fanglomerates whose quartz grains and quartzarenite fragments of variable roundness and shape were derived from a sedimentologically restored largely southeastward advancing late Paleozoic allochthonous lobe of mostly quartzarenite of the Ordovician Vinini Formation. Chert fragments in the conglomerates probably were derived mostly from Devonian Slaven Chert, including a widespread thick melange unit of the Slaven in the footwall of the Coyote thrust. Some chert pebbles may have been derived from the Ordovician Vinini Formation.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr01402","usgsCitation":"Berger, V.I., Singer, D.A., Theodore, T., Harris, A.G., and Stevens, C., 2001, Sedimentology of the Pennsylvanian and Permian Strathearn Formation, Northern Carlin Trend, Nevada; with a section on microfossil controls on age of the Strathearn Formation: U.S. Geological Survey Open-File Report 2001-402, v, 38 p., https://doi.org/10.3133/ofr01402.","productDescription":"v, 38 p.","numberOfPages":"43","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":159992,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0402/report-thumb.jpg"},{"id":3001,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0402/","linkFileType":{"id":5,"text":"html"}},{"id":59753,"rank":4,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0402/pdf/of01-402.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":390216,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_45104.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Nevada","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -116.500,\n              41.1250\n            ],\n            [\n              -116.250,\n              41.1250\n            ],\n            [\n              -116.250,\n              41\n            ],\n            [\n              -116.500,\n              41\n            ],\n            [\n              -116.500,\n              41.1250\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fbb02","contributors":{"authors":[{"text":"Berger, Vladimir I.","contributorId":15246,"corporation":false,"usgs":true,"family":"Berger","given":"Vladimir","email":"","middleInitial":"I.","affiliations":[],"preferred":false,"id":205746,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Singer, Donald A. dsinger@usgs.gov","contributorId":5601,"corporation":false,"usgs":true,"family":"Singer","given":"Donald","email":"dsinger@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":205745,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Theodore, Ted G.","contributorId":57840,"corporation":false,"usgs":true,"family":"Theodore","given":"Ted G.","affiliations":[],"preferred":false,"id":205748,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Harris, Anita G.","contributorId":50162,"corporation":false,"usgs":true,"family":"Harris","given":"Anita","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":205747,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stevens, Calvin H.","contributorId":59848,"corporation":false,"usgs":true,"family":"Stevens","given":"Calvin H.","affiliations":[],"preferred":false,"id":205749,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The cruises were conducted in 1995 aboard the NOAA Ship McArthur (M-1-95-MB) and in 1995 and 1997 aboard the R/V Point Sur (P-2-95-MB and P-1-97-MB). Scientists and representatives from the Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), the California Department of Fish and Game (CDFG), the University of California Santa Cruz (UCSC), and the San Jose State University Moss Landing Marine Laboratory (SJSU-MLML) supported the research effort.\n\nIn this report we present sediment descriptions, sediment textural data, physical property logs, station metadata, and photographs of subcores from a total of three hundred and eighty four sample stations. At these sites either a box corer, MultiCore™r, grab sampler or a combination of these sampling devices were used to collect the sea floor sediments. The report is presented in an interactive web-based format with each mapped core station linked to the corresponding description and photo, and to a spreadsheet of surface texture and other sampling data.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr01107","usgsCitation":"Orzech, K.M., Dahl, W.E., and Edwards, B.D., 2001, Core descriptions, core photographs, physical property logs and surface textural data of sediment cores recovered from the continental shelf of the Monterey Bay National Marine Sanctuary during the research cruises M-1-95-MB, P-2-95-MB, and P-1-97-MB: U.S. Geological Survey Open-File Report 2001-107, 21 p., https://doi.org/10.3133/ofr01107.","productDescription":"21 p.","numberOfPages":"21","costCenters":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":160879,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr01107.PNG"},{"id":2852,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0107/","linkFileType":{"id":5,"text":"html"}},{"id":282054,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0107/pdf/maintext.pdf"},{"id":282055,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/2001/0107/pdf/indexmap.pdf"}],"country":"United States","state":"California","otherGeospatial":"Monterey Bay National Marine Sanctuary","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -123.0,36.5 ], [ -123.0,37.916667 ], [ -121.75,37.916667 ], [ -121.75,36.5 ], [ -123.0,36.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad9e4b07f02db6852ed","contributors":{"authors":[{"text":"Orzech, Kevin M.","contributorId":38640,"corporation":false,"usgs":true,"family":"Orzech","given":"Kevin","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":205495,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dahl, Wendy E.","contributorId":25079,"corporation":false,"usgs":true,"family":"Dahl","given":"Wendy","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":205494,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Edwards, Brian D. bedwards@usgs.gov","contributorId":3161,"corporation":false,"usgs":true,"family":"Edwards","given":"Brian","email":"bedwards@usgs.gov","middleInitial":"D.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":205493,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Data from marine sediments suggest that deposits from two asteroid impacts (one close, one far away) may be preserved in the Badlands. These impact-generated deposits may represent late Maestrichtian events or possibly the terminal K-T event. Interpretation is supported by paleontological correlation, sequence stratigraphy, magnetostratigraphy, and strontium isotope geochronology. This research is founded on nearly a decade of NPS approved field work in Badlands National Park and a foundation of previously published data and interpretations.  The K-T boundary occurs within or near the base of a stratigraphic interval referred to as the \"Interior Zone.\" We interpret the stratigraphy of the Interior Zone as a series of distinct, recognizable lithologic members and units from oldest to youngest, an upper weathered interval of the Elk Butte Member of the Pierre Shale (early late Maestrichtian), a complete (albeit condensed) interval of Fox Hill Formation, a pedogenically altered K-T Boundary \"Disturbed Zone,\" and a generally unresolved sequence of marine to marginal marine units ranging in age from possibly latest Maestrichtian to late Paleocene (the \"Yellow Mounds\"), that underlie a basal red clay unit (the late Eocene overbank channel facies of the Chamberlain Pass Formation at the base of the White River Group). Within this sequence is a series of unconformities that all display some degree of subaerial weathering and erosion. The dating of marine fossils above and below these unconformities are in line with generally accepted global sea-level changes recognized for the late Campanian through early Eocene. Within the greater framework of regional geology, these findings support that the Western Interior Seaway and subsequent Cannonball Seaway were dependently linked to the changing base-level controlled by sea-level of the global ocean through the Gulf of Mexico and possibly the Arctic Ocean. The variation of facies preserved in Late Cretaceous strata in the Badlands National Park area were in part controlled by local or regional tectonic blocks that were either rising or sinking contemporaneous with deposition.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0156","issn":"0566-8174","usgsCitation":"Stoffer, P.W., Messina, P., Chamberlain, J.A., and Terry, D.O., 2001, The Cretaceous-Tertiary boundary interval in Badlands National Park, South Dakota: U.S. Geological Survey Open-File Report 2001-56, 49 p., https://doi.org/10.3133/ofr0156.","productDescription":"49 p.","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":285888,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0056/","linkFileType":{"id":5,"text":"html"}},{"id":282010,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0056/pdf/of01-056.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":285887,"rank":3,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0156.jpg"}],"country":"United States","state":"South Dakota","otherGeospatial":"Badlands National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -102.446,43.476 ], [ -102.446,43.58 ], [ -102.277,43.58 ], [ -102.277,43.476 ], [ -102.446,43.476 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67e6bf","contributors":{"authors":[{"text":"Stoffer, Philip W.","contributorId":32559,"corporation":false,"usgs":true,"family":"Stoffer","given":"Philip","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":185316,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Messina, Paula","contributorId":70005,"corporation":false,"usgs":true,"family":"Messina","given":"Paula","email":"","affiliations":[],"preferred":false,"id":185317,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chamberlain, John A.

The analytical method uses liquid-liquid extraction (LLE) and gas chromatography/mass spectrometry (GC/MS). Good precision and accuracy were demonstrated in reagent water, urban surface water, and ground water. The mean accuracies as percentages of the true compound concentrations from water samples spiked at 10 and 50 nanograms per liter ranged from 68 to 171 percent, with standard deviations in concentrations of 27 nanograms per liter or less. The method detection limit for all compounds was 5.9 nanograms per liter or less for 247-milliliter samples. This method is valuable for acquiring information about the fate and transport of these mosquito insecticides and one synergist in water.

In this report, we present acquisition parameters, data, and interpretations of seismic images that were acquired in the OU-1 area of GAFB during July 1999 (Fig. 2). GAFB is scheduled for conversion to civilian use, however, during its years as an Air Force base, trichlorethylene (TCE) was apparently introduced into the subsurface as a result of spills during normal aircraft maintenance operations. To comply with congressional directives, TCE contaminant removal has been ongoing since the early-tomid 1990s. However, only a small percentage of the TCE believed to have been introduced into the subsurface has been recovered, due largely to difficulty in locating the TCE within the subsurface.\n\nBecause TCE migrates within the subsurface by ground water movement, attempts to locate the TCE contaminants in the subsurface have employed an array of ground-water monitoring and extraction wells. These wells primarily sample within a shallow-depth (~40 m) aquifer system. Cores obtained from the monitoring and extraction wells indicate that the aquifer, which is composed of sand and gravel channels, is bounded by aquitards composed largely of clay and other fine-grained sediments. Based on well logs, the aquifer is about 3 to 5 m thick along the seismic profiles. A more thorough understanding of the lateral variations in the depth and thickness of the aquifer system may be a key to finding and removing the remaining TCE. However, due to its complex depositional and tectonic history, the structural and stratigraphic sequences are not easily characterized. An indication of the complex nature of the structure and stratigraphy is the appreciable variation in stratigraphic sequences observed in some monitoring wells that are only a few tens of meters apart.\n\nTo better characterize the shallow (upper 100 m) stratigraphy beneath GAFB, the US Environmental Protection Agency (USEPA) contracted the US Geological Survey (USGS) to acquire three seismic reflection/refraction profiles within an area known as Operational Unit #1 (OU-1). The principal objective of the seismic survey was to laterally characterize the subsurface with respect to structure and stratigraphy. In particular, we desired to (1) laterally “map” stratigraphic units (particularly aquifer layers) that were previously identified in monitoring wells within the OU-1 area and (2) identify structures, such as faults and folds, that affect the movement of ground water. Knowledge of lateral variations in stratigraphic units and structures that may affect those units is useful in constructing ground-water flow models, which aid in identifying possible TCE migration paths within the subsurface. Stratigraphic and structural characterization may also be useful in identifying surface locations and target depths for future wells (Catchings et al., 1996). Proper siting of wells is important because a welldefined aquifer is apparently not present in all locations at GAFB, as indicated by lithologic logs from existing wells (Montgomery Watson, 1995). Proper depth placement of monitoring and extraction wells is important because wells that are too shallow will not sample within the aquifer, and wells that are too deep risk puncturing the aquitard and allowing contaminants to flow to deeper levels.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0160","usgsCitation":"Catchings, R.D., Gandhok, G., and Goldman, M.R., 2001, Stratigraphic and structural characterization of the OU-1 area at the former George Air Force Base, Adelanto, southern California: U.S. Geological Survey Open-File Report 2001-60, 55 p., https://doi.org/10.3133/ofr0160.","productDescription":"55 p.","numberOfPages":"55","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":161032,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0160.jpg"},{"id":281999,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0060/pdf/of01-60.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":2795,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0060/","linkFileType":{"id":5,"text":"html"}},{"id":405931,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_42708.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","city":"Adelanto","otherGeospatial":"George Air Force Base","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.399,\n              34.554\n            ],\n            [\n              -117.3440,\n              34.554\n            ],\n            [\n              -117.3440,\n              34.612\n            ],\n            [\n              -117.399,\n              34.612\n            ],\n            [\n              -117.399,\n              34.554\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b27e4b07f02db6b0f2c","contributors":{"authors":[{"text":"Catchings, R.

The habitat conditions of both reaches were of optimal quality, with a score of 18 upstream and 17 downstream as determined by use of the U.S. Environmental Protection Agency's Rapid Bioassessment Protocols, and are capable of supporting fish communities. The Shannon Index was 2.95 upstream and 2.61 downstream of the lake, indicating that both reaches are slightly impacted by species richness and individual evenness among the species. Downstream, the dominant taxa was twice that of the co-dominant taxa. The Jaccards Coefficient and the Index of Similarity statistically shows these communities are similar, with scores of 0.76 and 0.86, respectively. Of the 19 species captured downstream, 16 of those also were captured upstream.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0180","collaboration":"Prepared in cooperation with the U.S. Army Corps of Engineers, Baltimore District","usgsCitation":"Brightbill, R., and Bilger, M.D., 2001, Fish-community composition in Ouleout Creek, in the vicinity of East Sidney Lake, Delaware County, New York, 2000: U.S. Geological Survey Open-File Report 2001-80, iii, 12 p., https://doi.org/10.3133/ofr0180.","productDescription":"iii, 12 p.","onlineOnly":"Y","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":2806,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0080/ofr20010080.pdf","text":"Report","size":"122 KB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2001-0080"},{"id":160569,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0080/coverthb.jpg"}],"contact":"<p><a href=\"mailto:dc_pa@usgs.gov\" data-mce-href=\"mailto:dc_pa@usgs.gov\">Director</a>, <a href=\"https://pa.water.usgs.gov/\" data-mce-href=\"https://pa.water.usgs.gov/\">Pennsylvania Water Science Center</a><br> U.S. Geological Survey <br> 215 Limekiln Road <br> New Cumberland, PA 17070</p>","tableOfContents":"<ul><li>Abstract</li><li>Introduction</li><li>Description of dam and stream study reaches</li><li>Study methods</li><li>Fish-community composition</li><li>Summary</li><li>References cited</li><li>Appendix</li></ul>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cde4b07f02db544af2","contributors":{"authors":[{"text":"Brightbill, R.A.","contributorId":79523,"corporation":false,"usgs":true,"family":"Brightbill","given":"R.A.","email":"","affiliations":[],"preferred":false,"id":205415,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bilger, Michael D.","contributorId":14861,"corporation":false,"usgs":true,"family":"Bilger","given":"Michael","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":205414,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Optical backscatterance sensors and water samples were used to monitor suspended sediment at one site in Suisun Bay, three sites in San Pablo Bay, two sites in Central San Francisco Bay, and three sites in South San Francisco Bay. Sensors were positioned at two depths at most sites. Water samples were collected periodically and were analyzed for concentrations of suspended sediment. The results of the analyses were used to calibrate the electrical output of the optical backscatterance sensors. This report presents the data-collection methods used and summarizes the suspended-sediment concentration data collected from October 1998 through September 1999.
