Previously, detailed investigations of sinkholes were limited to Alabama and Missouri, with the most comprehensive being in Alabama. An investigation of the remainder of the area was made in 1981 to regionalize previous findings. More than 850 sites of sinkhole development have been identified in 19 States. It is estimated that more than 6,500 sinkholes or related features have formed at these sites. Most have occurred since 1950. Based on information available, States most impacted are Alabama, Florida, Georgia, Missouri, Pennsylvania, and Tennessee.</p>\n<p>The total cost of damage and associated protective measures resulting from induced sinkholes is unknown. Costs reported for a limited number of sites were about $170 million--expended almost entirely after 1970. About $140 million were expended at five dams in four States and to repair or protect highways in two States.</p>\n<p>Sinkholes are of two types, natural and induced {accelerated or caused by man}. The sudden development of both types results from the collapse of the roof of a cavity or cavern in rock, or from the downward migration of unconsolidated deposits into solutionally enlarged openings in the top of bedrock. The occurrence of sinkholes resulting from bedrock roof collapses, in comparison with the occurrence of sinkholes resulting from downward migration of unconsolidated deposits, is rare.</p>\n<p>Induced sinkholes are of two types: those resulting from a decline in water level due to ground-water withdrawals and those resulting from construction. Sinkholes resulting from water-level declines are caused by loss of buoyant support, increase in velocity of water movement, water-level fluctuations, and induced recharge. Most induced sinkholes resulting from construction are caused by the diversion or impoundment of surface drainage over unconsolidated deposits resting on openings in the top of bedrock. Collapse mechanisms include loading, saturation, and piping.</p>\n<p>Assessment of existing or potential sinkhole problems at a site requires recognition of features associated with sinkhole development and knowledge of triggering mechanisms that cause sinkholes. Natural sinkhole development is generally not predictable. Induced sinkhole development is predictable in some instances, but is predictable only in the sense that it will occur in a particular area. The most predictable development results from dewatering by wells, quarries, and mines.</p>\n<p>Alternatives that allow avoiding or minimizing sinkhole hazards are most numerous when a problem or potential problem is recognized during site evaluation. The number of alternatives declines after the beginning of site development. Where sinkhole development is predictable, zoning of land use can minimize hazards.</p>","language":"English","publisher":"U.S. Government Print Office","doi":"10.3133/cir968","usgsCitation":"Newton,

There is a 1 to 5% probability that Carver Lake, located at elevation 7,800 ft above sea level on the east slope of South Sister mountain, Oregon, could catastrophically empty. At the U.S. Geological Survey gage (14075000) on Squaw Creek between Carver Lake and Sisters, the magnitude of the breakout flood would be 10 times that of a 1% probability meteorological flood. In Sisters, the magnitude of the breakout flood would be about five times that of a 1% probability meteorological flood. Several conditions at Carver Lake indicate the potential hazard: (1) The lake is very deep for its size; the lake contains 740 acre-ft of water and is more than 100 ft deep; (2) There is a probability that a large magnitude avalanche and consequent overtopping of the lake could occur. There are steep slopes of unstable volcanic rock and an extensively cravassed glacier located above the lake; (3) The moraine dam confining the lake is steep-faced, rendering the dam unstable, and unvegetated making it highly erodible; (4) Large amounts of readily erodible material available for transport would increase the magnitude of a large flood and keep the flood from attenuating in the steep reaches of the Squaw Creek channel; (5) and, Geologically, there is a greater than normal possibility for the area to become seismically active. Earthquakes could cause rock and ice to fall into the lake. A one-dimensional unsteady-state streamflow model was used to route a hypothetical flood down the Squaw Creek drainage. This scenario creates a starting hydrograph with a peak of 180,000 cu ft/sec. The ensuing hypothetical flood would incorporate readily erodible debris and sediments in the steep canyons, increasing the total volume of the flood by a factor of two. As the peak emerges from the steeper slopes into a more gently sloping valley 8 miles from the lake, the peak would attenuate to 47,000 cu ft/sec. At the Geological Survey gage at river mile 26.6, the peak would attenuate to 21,000 cu ft/sec. In Sisters on the alluvial fan, at about 20 miles downstream from the lake, the peak would continue to attenuate to 9,800 cu ft/sec.

This map is a revision of an earlier one (Moore and Wolfe, 1976). Detail of pyroclastic and alluvial deposits has been reduced for clarity on this uncolored version, and eolian deposits, represented by numerous active dunes of basaltic ash, have been completely omitted. Small cinder cones developed over rootless vents on the basalt flow (Qbb) of = vent 2019 have also been omitted. In addition, a few changes have been made in correlations of flows and vents. The stratigraphic classification has been modified because magnetic-polarity determinations and new K-Ar ages indicate that the physiographically defined Tappan and Woodhouse age groups (Moore and others, 1976) overlap significantly in age, and the rocks of those age groups are now assigned to the Brunhes or Matuyama Polarity Chronozones (Mankinen and Dalrymple, 1979).</p><p>The San Francisco field, which is largely Pliocene and Pleistocene in age, is in northern Arizona, just north of the broad transition zone between the Colorado Plateau and the Basin and Range province. It is one of several dominantly basaltic volcanic fields of late Cenozoic age situated near the southern margin of the Colorado Plateau. The East map area encompasses approximately 1,220 km<sup>2</sup>.</p><p>The volcanic field contains rocks ranging in composition from basalt to rhyolite--the products of eruption through Precambrian basement rocks and approximately a kilometer of overlying, nearly horizontal, Paleozoic and Mesozoic sedimentary rocks. About 500 km<sup>3</sup> of erupted rocks cover about 5,000 km<sup>2</sup> of predominantly Permian and locally preserved Triassic sedimentary rocks that form the erosionally stripped surface of the Colorado Plateau in northern Arizona.</p><p>In the East map area, basalt, basaltic andesite and locally associated small dacite&nbsp;domes, and, in a few cases, andesite were extruded from numerous individual vents, each of which presumably erupted briefly and then became inactive. Such short-lived vents, represented mainly by cinder cones or tuff rings, are widely distributed over the map area, and their flows cover much of its surface. However, repeated eruption of andesite, dacite, and rhyolite domes and flows formed the O'Leary Peak eruptive center in the northwest part of the map area, and flows of andesite (Qa<sub>1</sub> and Qa<sub>2</sub>) from the San Francisco Mountain stratovolcano entered the East map area from the west.</p><p>A northeastward progression of volcanism during the past 15 m.y., from central Arizona into the San Francisco volcanic field, is shown by the compilation of Luedke and Smith (1978). Although complicated in detail, a general northeastward to eastward progression of volcanic activity is also apparent within the San Francisco volcanic field. Thus, much of the eruptive activity of the East map area occurred late in the development of the San Francisco field, and the East map area includes the youngest volcanic rocks of the field. These youngest rocks were formed during the Sunset Crater eruption, which occurred within the past 1,000 years (Smiley, 1958).</p><p>A northeast-trending, faulted monocline occurs near Doney Mountain in the north-central part of the East map area, and a broad north- to northwest-trending anticline occurs at the east edge of the map area. Nearby volcanic rocks are not folded or faulted by either structure.</p><p>Northwest-trending normal faults of small throw occur in the southern and northwestern parts of the map area. The faults in the northwestern part transect basalt flows of Matuyama and Brunhes ages (Tmb, Qmb, and Qbb). The volcanic rocks are not faulted elsewhere in the East map area. However, local northwestward elongation and alignment of vent deposits, as shown for example by the fissure deposits of the Sunset Crater eruption (Qbsbf), indicate the presence of a northwest-trending fracture system that apparently localized some of the eruptive feeders. </p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/mf1960","usgsCitation":"Moore, R.B., and Wolfe, E.W., 1987, Geologic map of the east part of the San Francisco Volcanic Field, north-central Arizona: U.S. Geological Survey Miscellaneous Field Studies Map 1960, Report: 46 p.; 2 Plates: 38.07 x 58.09 inches and 38.52 x 50.01 inches, https://doi.org/10.3133/mf1960.","productDescription":"Report: 46 p.; 2 Plates: 38.07 x 58.09 inches and 38.52 x 50.01 inches","costCenters":[],"links":[{"id":180464,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/mf/1960/report-thumb.jpg"},{"id":105137,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_5529.htm","linkFileType":{"id":5,"text":"html"},"description":"5529"},{"id":361001,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/mf/1960/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":361002,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1960/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":361003,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/mf/1960/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"50000","datum":"National Geodetic Vertical Datum of 1929","country":"United States","state":"Arizona","otherGeospatial":"San Francisco volcanic field","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.61749999999999,35.134166666666665 ], [ -111.61749999999999,35.6175 ], [ -111.11749999999999,35.6175 ], [ -111.11749999999999,35.134166666666665 ], [ -111.61749999999999,35.134166666666665 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae3e4b07f02db689190","contributors":{"authors":[{"text":"Moore, Richard B. rmoore@usgs.gov","contributorId":1464,"corporation":false,"usgs":true,"family":"Moore","given":"Richard","email":"rmoore@usgs.gov","middleInitial":"B.","affiliations":[{"id":405,"text":"NH/VT office of New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":263640,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wolfe, Edward W.","contributorId":79878,"corporation":false,"usgs":true,"family":"Wolfe","given":"Edward","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":263639,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Seven pilot projects (four surface water projects and three groundwater projects) have been started. The preliminary plans for the surface water quality assessment of the Kentucky River basin pilot project are described. The Kentucky River basin drains an area of approximately 7,000 sq mi in east central Kentucky and is underlain by rocks that range in composition from limestone to sandstone and shale. Because greater than 95% of the basin population relies on surface water, surface water quality is of great concern. Land use practices that affect the surface water quality in the basin include agriculture, forestry, oil and gas production, coal mining, and urbanization. Water quality concerns resulting from the various land uses include the effects of: oil and gas field brine discharges; agricultural chemicals; sedimentation caused by coal mining; and trace element impacts from industrial and urban environments. Assessment activity is designed to occur over a 9-year period of time. During the first 3-year period of the cycle, concentrated data acquisition and interpretation will occur. For the next 6 years, sample collection will occur at a much lower level of intensity to document the occurrence of any gross changes in water quality. This 9-year cycle will then be repeated. Historical data will be evaluated to provide, to the extent possible, a description of existing and past trends in water quality conditions and to develop conceptual models that relate the observed conditions to the sources and causes, both natural and human-controlled. New data will be collected to verify the water quality conditions documented by historic data, to track long-term trends in water quality, to intensify temporal and spatial sampling densities, and to improve the understanding of the relations between water quality conditions and causative factors.

The aquifer is recharged mainly by streamflow losses in the outcrop area of the Edwards aquifer and is discharged by major springs located at considerable distances, as much as 150 mi, from the areas of recharge, and by wells. Groundwater flow within the Edwards aquifer of the San Antonio region was simulated to investigate concepts relating to the storage and flow characteristics. A general purpose, finite difference model, modified to provide the capability of representing barrier faults, was used to simulate groundwater flow and storage in the aquifer. The simulations investigated the effects of complex geologic structures and significant changes in transmissivity, anisotropy, and storage coefficient, with initial values based on concepts developed in previous studies. Results of the simulations confirmed the original estimates of transmissivity values (&gt; 100 sq ft/sec) in the confined zone of the aquifer between San Antonio and Comal Springs. A storage coefficient of 0.05 in the unconfined zone of the aquifer produced the best simulation of water levels and springflow. A major interpretation resulting from the simulations is that two essentially independent areas of regional flow were identified in the west and central part of the study area. Flow from the two areas converges at Comal Springs. The directions of computed flux vectors reflected the presence of major barrier faults which locally deflect patterns of groundwater movement. The most noticeable deflection is the convergence of flow through the geologic structural opening, the Knippa gap, in eastern Uvalde County. A second significant interpretation is that groundwater flow in northeastern Bexar, Comal, and Hays Counties is diverted by barrier faults toward San Marcos Springs, a regional discharge point.

Mineral surveys were requested for 31,371 acres of the Fort Piute Wilderness Study Area. In this report the area studied is referred to as \"the study area\". Examination of mines and prospects in the area was accomplished by the U.S. Bureau of Mines in 1981 and 1982. Field investigations of the area were carried out by the U.S. Geological Survey in 1983 and 1985. No mines or prospects, few mining claims, and no identified resources are located within the wilderness study area. Moderate and low potential for gold resources appears limited to outcrops of gneiss and granite exposed along the eastern side of the Piute Range. Available information indicates that there is no potential for energy resources, including oil and gas, uranium, or geothermal, in the study area.</p>","largerWorkTitle":"Mineral resources of Wilderness Study Areas: Eastern California Desert Conservation Area, California","language":"English","publisher":"U.S. Government Printing Office","doi":"10.3133/b1713C","usgsCitation":"Nielson, J.E., Frisken, J.G., Jachens, R.C., and McDonnell, J.R., 1987, Mineral resources of the Fort Piute Wilderness Study Area, San Bernardino County, California: U.S. Geological Survey Bulletin 1713, Report: v, 12 p.; Plate: 23.00 x 35.50 inches, https://doi.org/10.3133/b1713C.","productDescription":"Report: v, 12 p.; Plate: 23.00 x 35.50 inches","startPage":"C1","endPage":"C12","costCenters":[],"links":[{"id":61234,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/bul/1713c/plate-1.pdf","text":"Plate 1","size":"4.53 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Plate 1"},{"id":61235,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/bul/1713c/report.pdf","text":"Report","size":"1.27 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":164232,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/bul/1713c/report-thumb.jpg"}],"country":"United States","state":"California","county":"San Bernardino County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -115.05157470703126,\n              35.337533782800946\n            ],\n            [\n              -115.13946533203124,\n              35.40024478679507\n            ],\n            [\n              -115.18890380859374,\n              35.382332329032984\n            ],\n            [\n              -115.27679443359375,\n              35.27253175660236\n            ],\n            [\n              -115.31524658203124,\n              35.11990857099681\n            ],\n            [\n              -115.3399658203125,\n              34.786739162702524\n            ],\n            [\n              -115.32623291015625,\n              34.69646117272349\n            ],\n            [\n              -115.27130126953125,\n              34.59930237746263\n            ],\n            [\n              -115.15869140624999,\n              34.55407346090554\n            ],\n            [\n              -115.02960205078125,\n              34.5020297944346\n            ],\n            [\n              -114.9169921875,\n              34.58799745550482\n            ],\n            [\n              -114.86480712890626,\n              34.70549341022544\n            ],\n            [\n              -114.84558105468749,\n              34.836349990763864\n            ],\n            [\n              -114.82635498046875,\n              35.02774729487063\n            ],\n            [\n              -114.83184814453124,\n              35.15584570226544\n            ],\n            [\n              -115.05157470703126,\n              35.337533782800946\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b06e4b07f02db69a320","contributors":{"authors":[{"text":"Nielson, Jane E.","contributorId":9701,"corporation":false,"usgs":true,"family":"Nielson","given":"Jane","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":210770,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Frisken, James G.","contributorId":76740,"corporation":false,"usgs":true,"family":"Frisken","given":"James","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":210772,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Jachens, Robert C. jachens@usgs.gov","contributorId":1180,"corporation":false,"usgs":true,"family":"Jachens","given":"Robert","email":"jachens@usgs.gov","middleInitial":"C.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":210771,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McDonnell, John R.

Areas with adequate, minimally adequate, or deficient data available for groundwater-quality evaluations are described. \r\n\r\nWide variations in chemical concentrations in the water occur within individual aquifers, as well as among the aquifers. The existing data base is not sufficient to describe fully the ground-water quality throughout the State; however, it does indicate that the water is generally suitable for most uses. In some aquifers, concentrations of fluoride, cadmium, and iron in the water exceed the U.S. Environmental Protection Agency's drinking-water standards. Dissolved solids, chloride, and sulfate may cause problems in some local areas. Water-quality data are sparse in many areas, and only general statements can be made regarding the areal distribution of chemical constituents. Few data are available to describe temporal variations of water quality in the aquifers. \r\n\r\nPrimary concerns related to special problem areas in Idaho include (1) protection of water quality in the Rathdrum Prairie aquifer, (2) potential degradation of water quality in the Boise-Nampa area, (3) effects of widespread use of drain wells overlying the eastern Snake River Plain basalt aquifer, and (4) disposal of low-level radioactive wastes at the Idaho National Engineering Laboratory. \r\n\r\nShortcomings in the ground-water-quality data base are categorized as (1) multiaquifer sample inadequacy, (2) constituent coverage limitations, (3) baseline-data deficiencies, and (4) data-base nonuniformity.","language":"ENGLISH","publisher":"U.S. G.P.O.,","doi":"10.3133/wsp2272","usgsCitation":"Yee, J., and Souza, W.R., 1987, Quality of ground water in Idaho: U.S. Geological Survey Water Supply Paper 2272, iv, 53 p. :ill., maps ;28 cm., https://doi.org/10.3133/wsp2272.","productDescription":"iv, 53 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":139471,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2272/report-thumb.jpg"},{"id":29856,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2272/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a73e4b07f02db643973","contributors":{"authors":[{"text":"Yee, Johnson J.","contributorId":13612,"corporation":false,"usgs":true,"family":"Yee","given":"Johnson J.","affiliations":[],"preferred":false,"id":146165,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Souza, William R.","contributorId":90295,"corporation":false,"usgs":true,"family":"Souza","given":"William","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":146166,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This study was conducted to evaluate the development potential of the shallow Upper Floridan aquifer as an alternate source of groundwater, especially for public supply. The Upper Floridan stores and transmits large quantities of water, mainly in a zone of high permeability in the lower part of the aquifer. The transmissivity of the aquifer ranges from &lt; 10,000 sq ft/day northwest of Albany, to as much as 150 ,000 sq ft/day south and southeast of Albany. Twenty-eight years of agricultural and industrial pumping has not produced a long-term decline of the water level in the Upper Floridan; the aquifer system remains at equilibrium. The Upper Floridan yields hard, calcium bicarbonate-type water but concentrations do not exceed State drinking water standards. In most of the study area , contaminants applied to or spilled on the land surface eventually can be expected to percolate through the overburden and reach the aquifer. Thus, it is important that wells be sited away from areas that have been used for the storage and disposal of potential contaminants and, probably to a lesser extent, the application of agricultural chemicals. In the area of greatest development potential east of the Flint River, wells may penetrate major groundwater conduits. By limiting drawdown during well development and during production, the likelihood of causing sinkholes to form can be minimized. Closed depressions, or sinks, throughout the Dougherty Plain probably are unsuitable as well sites, because (1) they are subject to flooding, (2) they collect water from upgradient areas and could concentrate potential contaminants, (3) water probably percolates through their bottoms and could transport contaminants into the aquifer, and (4) the depressions may overlie limestone cavities filled with sand or clay that could interfere with well yield, development, and production.

The High Shoals Granite batholith in the Kings Mountain belt of south-central North Carolina consists of coarse-grained, megacrystic biotite granite with a strong, nearly vertical, gneissoid, foliation, defined by parallel feldspar megacrysts and biotite. U-Ph isotopic data on zircons from the granite yield a concordant age of 317 Ma (Pennsylvanian). This pervasively deformed late Paleozoic granite in the central Piedmont is far west of those known in the Kiokee and Raleigh belts. Field relationships indicate that the High Shoals Granite was emplaced during the late stages of regional F2 folding, close in time to the thermal peak of amphibolite-facies metamorphism. Mineral assemblages typical of Barrovian metamorphism are found in zones of decreasing grade away from the High Shoals contact. These zones, delimited by a kyanite(out)-sillimanite (in) isograd which completely surrounds the batholith and by part of a regional chloritoid (out)-staurolite (in) isograd west and southwest of it, conform to the shape of the batholith and cut across F2 folds. Furthermore, hornblendes from epidoteamphibolite facies to upper amphibolite facies metamorphic rocks in the Kings Mountain belt of North Carolina and South Carolina yield 40Ar/39Ar plateau ages of 318 to 323 Ma. These dates are analytically the same as the crystallization age of High Shoals Granite as established of zireon using the U-Ph method and demonstrate the synchroneity of intrusion of the High Shoals with the dominant regional metamorphism in this part of the Kings Mountain belt.&nbsp;</p>","language":"English","publisher":"American Journal of Science","doi":"10.2475/ajs.287.6.635","usgsCitation":"Horton,, J., Sutter, J.F., Stern, T.W., and Milton, D., 1987, Alleghanian deformation, metamorphism, and granite emplacement in the central Piedmont of the southern Appalachians: American Journal of Science, v. 287, no. 6, p. 635-660, https://doi.org/10.2475/ajs.287.6.635.","productDescription":"26 p.","startPage":"635","endPage":"660","costCenters":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"links":[{"id":373597,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Southern Appalachians","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -84.3310546875,\n              34.542762387234845\n            ],\n            [\n              -83.023681640625,\n              34.768691457552706\n            ],\n            [\n              -81.793212890625,\n              35.505400093441324\n            ],\n            [\n              -80.255126953125,\n              36.73888412439431\n            ],\n            [\n              -78.77197265625,\n              38.02213147353745\n            ],\n            [\n              -77.969970703125,\n              38.788345355085625\n            ],\n            [\n              -77.838134765625,\n              39.26628442213066\n            ],\n            [\n              -79.16748046874999,\n              39.2832938689385\n            ],\n            [\n              -80.167236328125,\n              38.12591462924157\n            ],\n            [\n              -81.793212890625,\n              37.36142550190517\n            ],\n            [\n              -83.21044921875,\n              36.97622678464096\n            ],\n            [\n              -84.495849609375,\n              36.146746777814364\n            ],\n            [\n              -84.91333007812499,\n              35.35321610123823\n            ],\n            [\n              -84.8583984375,\n              34.58799745550482\n            ],\n            [\n              -84.122314453125,\n              34.43409789359469\n            ],\n            [\n              -84.3310546875,\n              34.542762387234845\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"287","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Horton,, J.

At Del Puerto Canyon, on the east side of the Diablo Range, a pilot study of the upper Jurassic Lotta Creek Formation gives in situ paleomagnetic directions grouped around the present geomagnetic field, suggesting magnetic overprinting long after deposition and folding. We suggest that the loss of original magnetization could be the result of long burial at about 7 km depth, followed by Late Tertiary uplift; the possibility of chemical remagnetization, however, can not be excluded. Paleomagnetic data from sandstones from the Lower Cretaceous Great Valley sequence in the Wilbur Springs area suggest Cenozoic remagnetization that could be related to Pliocene and Pleistocene volcanic and hydrothermal activity in the area. The results from calcareous concretions in the Wilbur Springs area, from 21 sites from basalts and overlying sedimentary rocks of the Great Valley sequence at Stonyford, and from several sites in various rock types in the Coast Range ophiolite and Great Valley sequence near Paskenta suggest unblocking of magnetization during the long period of burial at depth of 7 km or more and remagnetization during tectonic uplift in the Late Cretaceous or Tertiary. Chemical remagnetization, however, can not be excluded. The paleomagnetic data from six sites in Lower Cretaceous sedimentary rocks of the Days Creek Formation in southwest Oregon, which overlies a dismembered ophiolite, fail the fold test. In situ paleomagnetic directions group near the expected Tertiary field directions. These sedimentary rocks may have been remagnetized during a major Eocene tectonic event known to have occurred in this region. The paleomagnetic results confirm that the Coast Range ophiolite and the seemingly little-deformed Great Valley sequence in northern California, as well as correlative rocks in southwest Oregon have had a complex tectonic history. Once the nature and timing of these events are better understood, the timing of remagnetization may be further constrained, which, in turn, could give further insight into the nature of the tectonic events</p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB092iB05p03487","usgsCitation":"Frei, L., and Blake, M.C., 1987, Remagnetization of the Coast Range Ophiolite and Lower Part of the Great Valley Sequence in Northern California and Southwest Oregon: Journal of Geophysical Research B: Solid Earth, v. 92, no.

Conglomerates are found in the western part of the basin; siliceous pebbles diminish in size both southward and eastward across the basin, becoming rare to nonexistent in the eastern part. There is great variation in the internal stratigraphy of the Ojo Alamo: Individual sandstone or mudstone beds thicken, thin, and pinch out laterally.

The formation varies in composition from one to as many as five sandstone beds with interbeds of siltstone or mudstone.</p><p>Dinosaur bone has been found within the Ojo Alamo at several sites in the western part of the basin.

To date, no Cretaceous pollen has been found at or above the stratigraphic level of dinosaur bone within the Ojo Alamo Sandstone. Near Barrel Spring, in the southwest part of the basin, both dinosaur bone and Paleocene pollen have been found. One bone, found at the top of the Ojo Alamo, was loose on the surface, and its significance is therefore equivocal. Dinosaur bone, however, has also been found in place in the upper part of the Ojo Alamo about 1.6 km (1 mi) west of Barrel Spring, at about the same stratigraphic level as Paleocene pollen from a site just east of Barrel Spring. Because there is no apparent unconformity between the highest in-place bone level and the Paleocene pollen level in this area, the Ojo Alamo dinosaurs, if not reworked, are Paleocene in age at this site and probably throughout the San Juan Basin.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/SPE209-p17","usgsCitation":"Fassett, J.E., Lucas, S.G., and O’Neill, F., 1987, Dinosaurs, pollen and spores, and the age of the Ojo Alamo Sandstone, San Juan Basin, New Mexico: GSA Special Papers, v. 209, p. 17-34, https://doi.org/10.1130/SPE209-p17.","productDescription":"18 p.","startPage":"17","endPage":"34","costCenters":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"links":[{"id":370321,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Colorado, New Mexico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -108.709716796875,\n              35.93354064249312\n            ],\n            [\n              -106.864013671875,\n              35.93354064249312\n            ],\n            [\n              -106.864013671875,\n              37.45741810262938\n            ],\n            [\n              -108.709716796875,\n              37.45741810262938\n            ],\n            [\n              -108.709716796875,\n              35.93354064249312\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"209","noUsgsAuthors":false,"publicationDate":"1987-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Fassett, James E. jfassett@usgs.gov","contributorId":73590,"corporation":false,"usgs":true,"family":"Fassett","given":"James","email":"jfassett@usgs.gov","middleInitial":"E.","affiliations":[{"id":165,"text":"Central Energy Resources Team","active":false,"usgs":true}],"preferred":false,"id":777646,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lucas, S.

These formations have been known to be Late Cretaceous in age since the early 1900s. Now, with the greatly renewed interest in rocks adjacent to mass extinction boundaries, it is important to place more precise ages on such rock units as the Fruitland and Kirtland. Deposition of the Fruitland and Kirtland was closely related to deposition of the underlying marine-regressive Pictured Cliffs Sandstone. Because the Pictured Cliffs was deposited as a strandline sandstone in a subsiding seaway, its stratigraphic expression, when related to a time horizon (the Huerfanito Bentonite Bed), is a series of rising-to-the-northeast, time transgressive, stair steps. Thus, time lines (or horizons) drawn parallel to the Huerfanito cut through the marine Lewis Shale, the strandline Pictured Cliffs Sandstone, and the continental Fruitland Formation and Kirtland Shale.</p><p>Ammonites have been collected and identified from various stratigraphic levels within the Lewis Shale around the northwest, north, and east sides of the San Juan Basin. These fossils can be tied in to the established ammonite zonation of the Western Interior seaway. Because some of these ammonite zones have been radiometrically dated outside the San Juan Basin, it is possible to project these dated faunal zones from the Lewis Shale along time lines into the Fruitland Formation and Kirtland Shale and thereby estimate the age of those rocks. Based on these projections the part of the Fruitland and Kirtland laterally time-equivalent to the Lewis Shale is estimated to range from 73.2 ± 0.7 Ma to 73.9 ± 0.8 Ma.

Severe flooding accompanied the rainfall; 43 lives were lost and the flood was estimated to be the most expensive natural disaster of 1985 in the United States (Scatena, 1986). </p><p>The rainfall also triggered many slope failures. An especially large concentration of slope failures was associated with an area of moderate rainfall centered in the Germany Valley in Pendleton County, West Virginia (fig. 4.1A ). This report describes some preliminary results from our continuing research into the geological and meteorological controls on the distributions of slope failures in the Germany Valley area. </p><p>The Germany Valley is the first major anticlinal valley in the Valley and Ridge province east of the Allegheny structural front (Diecchio, 1986). Our interest is focused on the portion from near Mouth of Seneca, West Virginia, in the Onego 7 .5-minute quadrangle, to near Mill Gap, Virginia, in the Mustoe 7.5-minute quadrangle (patterned in figs. 4.1 and 4.2). This area was a natural experiment for studying the effects of the storm because rainfall varied systematically from southwest to northeast along the valley, while bedrock lithology and structure are nearly constant. Furthermore, variation of rock types across the valley allows comparisons among lithologies at given levels of precipitation. </p><p>The valley is floored by Ordovician carbonates of the Trenton, Black River, and St. Paul Groups and shales of the Martinsburg (Reedsville) Shale. The ridges are formed by sandstones of the Tuscarora and Oswego Sandstones, and the Juniata formation. The southwestern quarter of the valley is drained by Back Creek of the James River basin, and the remainder of the valley drains north and west to the North Fprk of the South Branch Potomac River. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Landslides of eastern North America (Circular 1008)","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"English","publisher":"U.S. Government Printing Office","publisherLocation":"Washington, D.C.","doi":"10.3133/cir10084","usgsCitation":"Jacobson, R.B., Cron, E.D., and McGeehin, J.P., 1987, Preliminary results from a study of natural slope failures triggered by the storm of November 3.5.1985, Germany Valley, West Virginia and Virginia: Chapter 4 in Landslides of eastern North America: U.S. Geological Survey Circular 1008, 6 p., https://doi.org/10.3133/cir10084.","productDescription":"6 p.","startPage":"11","endPage":"16","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"links":[{"id":343985,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Virginia, West Virginia","otherGeospatial":"Germany Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -80.7,\n              37.4\n            ],\n            [\n              -78,\n              37.4\n            ],\n            [\n              -78,\n              39.9\n            ],\n            [\n              -80.7,\n              39.9\n            ],\n            [\n              -80.7,\n              37.4\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"596f1e2ae4b0d1f9f0640786","contributors":{"authors":[{"text":"Jacobson, Robert B. 0000-0002-8368-2064 rjacobson@usgs.gov","orcid":"https://orcid.org/0000-0002-8368-2064","contributorId":1289,"corporation":false,"usgs":true,"family":"Jacobson","given":"Robert","email":"rjacobson@usgs.gov","middleInitial":"B.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":705330,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cron, Elizabeth D.","contributorId":193169,"corporation":false,"usgs":false,"family":"Cron","given":"Elizabeth","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":705331,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McGeehin, John P. mcgeehin@usgs.gov","contributorId":140956,"corporation":false,"usgs":true,"family":"McGeehin","given":"John","email":"mcgeehin@usgs.gov","middleInitial":"P.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true}],"preferred":false,"id":705332,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
