There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.</p><p>Oaks and Coch (1973) recently completed a detailed investigation of the geology and morphology of the area. An analysis of their geology and the pollen work of Whitehead (1972) has lead the authors to the following hypothesis concerning the hydrologic conditions that led to the formation of the peat in the swamp.</p><p>A permeable sand facies of the Norfolk Formation underlies Dismal Swamp. This facies was originally completely covered by the Sand Bridge Formation, which is a confining layer, and underlain by the impermeable Yorktown Formation. Movement of water eastward within the Norfolk Formation from the outcrop area on the top of the Suffolk Scarp was further restricted by a less permeable facies of the Norfolk east of the swamp; thereby creating an artesian head within the permeable sand facies of the Norfolk Formation.</p><p>Erosion during the Pleistocene age breached the Sand Bridge confining layer and allowed upward seepage of water along the shallow stream valleys. This seepage, combined with the abundant rainfall and naturally sluggish surface drainage, may have been sufficient to trigger the formation of peat along stream valleys about 9,000 years ago. The peat further inhibited surface drainage, which in turn, accelerated the accumulation of peat until the interfluve areas were covered. The present role of the Norfolk Formation in the hydrology of the swamp is not clear, but it is considered to be one of the most important aspects of the hydrology to be studied in future investigations.</p><p>Surface inflow is from small streams draining from the west. The flow of these streams varies widely, being generally less in the summer than in winter. Outflow is primarily through the Feeder Ditch-Dismal Swamp Canal system, which discharges at South Mills and Deep Creek locks.</p><p>Rates and direction of surface flow within the swamp are partly controlled by gates on many of the ditches. Inadequately controlled ditches penetrating the Norfolk Formation plus withdrawal of water from wells along Suffolk Scarp have altered the flow of ground water under the swamp. These modifications and the loss of water through the Dismal Swamp Canal have probably resulted in a generally drier swamp as indicated by changes in the vegetation. It is feasible to preserve Dismal Swamp, but more detailed studies of the hydrology are needed to aid in future management.</p>","language":"English","publisher":"U.S. Geological

Related flood data useful in planning and design also are included in the report.</p><p>Two distinct hydrologic regions are delineated within the State. The divisional boundary for these regions is, in general, the western divide of the James River basin. For each region, the 2-, 5-, 10-, 25-, 50-, and 100-year floods are related to basin and climatic characteristics by regression equations. Indices based on contributing drainage area size, elevation, and mean annual precipitation were found to be the most useful variables in estimation of South Dakota floods. Regional relationships based on these variables can be used to estimate floods of selected frequency at most ungaged sites where peak flows are not significantly affected by regulation or other manmade works. Equations and graphs presented are applicable to drainage basins with areas approximately from<br>0.1 to 4,000 square miles (0.3 to 10,400 square kilometres) in the Eastern Region and from 0.1 to 9,000 square miles (0.3 to 23,300 square kilometres) in the Western Region. Limitations on use of these equations are given and the accuracy of resulting estimates is discussed.</p><p>Flood characteristics are tabulated for 130 gaging stations having 10 or more years of record. These frequency data may provide the best estimates of floods at these gaged sites. Also, maximum flood peaks determined at 188 gaging stations and 52 miscellaneous sites are compared with regional flood relationships.</p><p>Individual relationships are presented for the main-stem portions of selected streams where significant regulation is a factor or where drainage areas exceed the limits of applicability of the regional relationships.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7435","usgsCitation":"Becker, L.D., 1974, A method for estimating magnitude and frequency of floods in

The study area comprises the valley floor and some of the foothills of the Sierra Nevada and the Coast Ranges, a total area of about 6,000 square miles.</p><p>Beneath most places in the valley, the base of the post-Eocene continental deposits is equivalent to the base of the Tehama Formation of Pliocene age, which in some places at least may be of late Oligocene and early Miocene age. The deposits consist of intercalated beds of gravel, sand, silt, clay, tuff, conglomerate, sandstone, siltstone, and claystone. And beneath large areas along the eastern side of the valley the deposits consist of basaltic and andesitic mudflows, tuff, tuff breccias, volcanic sandstones and conglomerates, and sand and gravel, as well as overlying nonvolcanic sediments. They contain most of the fresh ground water in the valley.</p><p>The structure of the base of the continental deposits is that of a large northward-trending syncline whose trend is interrupted only by the Sutter Buttes. In the subsurface, faulting has occurred mostly within the basal part of the deposits. Beneath the northeastern part of the valley, along the Chico monocline, faulting has occurred through probably the total thickness of the deposits.</p><p>The deposits range in thickness from zero near the margins of the valley to about 3,500 feet beneath the south-central part of the valley.

Nitrate was found in either trace concentrations or below detectable limits; however, ammonia nitrogen was usually detected in concentrations greater than 0.05 milligrams per liter. Orthophosphate phosphorus was detected in mean concentrations ranging from 0.01 to 0.05 milligrams per liter. Organic nitrogen and phosphorus were also detected in measurable concentrations.</p><p>Seasonal levels of dissolved oxygen indicated that the nutrients and other controlling factors were optimum for relatively high primary productivity. However, production varied both seasonally and areally in the lake. Primary productivity seemed highest in the eastern and middle parts of the lake.

All three basins are underlain by the Biscayne aquifer. They are, Snapper Creek Canal basin, where the Biscayne aquifer is of high permeability; the Snake Creek Canal basin, where the aquifer is of moderate permeability; and the Pompano-Cypress Canal basin, where the aquifer is of low permeability. In each basin, drainage is a function of permeability; thus, where the permeability of the aquifer is high, drainage is excellent. The coastal water-conrol structures are intended to afford flood protection in the three basins. In general the control operation criteria for flood control in newly developing areas in southeastern Florida do not provide adequate protection from flooding because of the time required for the aquifer to respond to changes in the controls. Adequate protection would require increasing the density of secondary drainage canals, but this could achieved only by reducing the quantity of water available for recharging those segments of the Biscayne aquifer adjacent to the canals.

Mapping in the Witch Lake quadrangle has filled the gap between well-studied areas of the Marquette trough and parts of Iron and Dickinson Counties and has helped to correlate units in the Baraga Group (Precambrian X). Iron-formations are important marker beds; because of their magnetic properties they can be traced with certainty through poorly exposed areas. The magnetic Fence River Formation is now known to be stratigraphically beneath the Bijiki Iron-formation Member of the Michigamme Formation but may be equivalent to the Greenwood Iron-formation Member which crops out in parts of the Marquette trough to the east The Hemlock Formation (volcanic) underlies the Fence River and has been traced from near its type locality in Iron County to the south flank of the Marquette trough.

They are divided into three groups primarily on the basis of degree of serpentinization.&nbsp;Group I consists of lens-shaped bodies of serpentinite 1 m<sup>2</sup> (10 ft<sup>2</sup>) to several 100 m<sup>2</sup> (1,000 ft<sup>2</sup>) in area. Relict textures and presence of bastite indicate that the original rock was harzburgite and dunite. Group II consists of bodies composed of partially serpentinized harzburgite and dunite and includes the large Mount Sorenson and American Creek bodies. Group III is dominantly hornblendite and pyroxenite, probably intrusive and not genetically related to groups I and II. The authors believe that the ultramafic bodies of groups I and II are alpine-type peridotites and may include dismembered ophiolitc. The Tintina fault system could have provided a zone of weakness along which mantle material was tectonically emplaced or it may have been a plate boundary in late Paleozoic time. If it represents a plate boundary, the metamorphic terrane which lies between the Tintina and Denali fault systems would have to be allochthonous, perhaps originating as a northward-moving slice of continental crustal material. During the course of the movement as the two continental masses approached and perhaps collided, mantle peridotite and oceanic crustal material were squeezed up along the continental margin onto the continental slice.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","usgsCitation":"Foster, H.L., and Keith, T.E., 1974, Ultramafic rocks of the Eagle quadrangle, east-central Alaska: Journal of Research of the U.S. Geological Survey, v. 2, no. 6, p. 657-669.","productDescription":"13 p.","startPage":"657","endPage":"669","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[],"links":[{"id":307199,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":307198,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1974/vol2issue6/report.pdf","text":"Report","size":"16.19 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -144,\n              63\n            ],\n            [\n              -144,\n              66\n            ],\n            [\n              -141,\n              66\n            ],\n            [\n              -141,\n              63\n            ],\n            [\n              -144,\n              63\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"2","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"568e493ae4b0e7a44bc41ad8","contributors":{"authors":[{"text":"Foster, Helen L.","contributorId":56195,"corporation":false,"usgs":true,"family":"Foster","given":"Helen","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":569339,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Keith, Terry E.C.","contributorId":79099,"corporation":false,"usgs":true,"family":"Keith","given":"Terry","email":"","middleInitial":"E.C.","affiliations":[],"preferred":false,"id":569340,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In the year following the detonation, this deformation reversed such that the final configuration represented a small east-west contraction from the pre-HANDLEY state. In the subsequent 2-year period, only minor deformation was detected. Thus, the overall response of Pahute Mesa may be described as stable. The explosion-induced deformation is thought to be partly due to slip on faults driven by the large-amplitude seismic waves from the explosion.

Only 31.7 percent of the population was nesting in trees; the remaining birds utilized duck blinds (28.7 percent), channel markers (21.8 percent), and miscellaneous man-made structures (17.8 percent). The geographical distribution of nesting ospreys has quite likely changed during the last several decades as suitable artificial nesting sites have become more available.

The chert is in green to gray mudstone, about 8 m beneath a conspicuous gray and yellow zeolitic tuff. The bedded chert contains molds of saline minerals and it grades southward and marginward into nodular chert. The nodular chert is of two varieties: relatively large lobate nodules that have greenish-brown interiors and abundant saline crystal molds, and relatively small lobate nodules that have gray interiors and a surface reticulation. The latter variety is the so-called snakeskin agate prized by lapidaries. Both nodular varieties characteristically have a thin white rind. The cherts are similar, if not identical, to cherts reported from Quaternary lacustrine deposits in eastern Africa and from Pleistocene to Jurassic lacustrine deposits in Wyoming.

Several thousand feet of dominantly detrital rocks occur above the Johnnie Formation in southern Nevada and the McCoy Creek Group in east-central Nevada. These detrital rocks consist of quartzite and siltstone in southern Nevada (the Stirling Quartzite, Wood Canyon Formation, and Zabriskie Quartzite) and dominantly quartzite (the Prospect Mountain Quartzite) in cast-central Nevada.

These basalts were fed from northeast-trending fissures that had much earlier served as vents for ash-flow tuffs and lavas, possibly including the tuff of Lunar Cuesta.</p>","language":"English","publisher":"U.S. Geological Survey","usgsCitation":"Ekren, E.B., Quinlivan, W.D., Snyder, R., and Kleinhampl, F.J., 1974, Stratigraphy, structure, and geologic history of the Lunar Lake Caldera of northern Nye County, Nevada: Journal of Research of the U.S. Geological Survey, v. 2, no. 5, p. 599-608.","productDescription":"10 p.","startPage":"599","endPage":"608","costCenters":[],"links":[{"id":402975,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":402973,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/journal/1974/vol2issue5/report.pdf"}],"country":"United States","state":"Nevada","county":"Nye County","otherGeospatial":"Lunar Lake caldera","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -115.99708557128905,\n              38.36534867623901\n            ],\n            [\n              -115.88310241699219,\n              38.43153880264903\n            ],\n            [\n              -115.85494995117188,\n              38.486919673341646\n            ],\n            [\n              -115.89271545410155,\n              38.556220194663595\n            ],\n            [\n              -116.00875854492188,\n              38.60989560714296\n            ],\n            [\n              -116.14677429199219,\n              38.58252615935333\n            ],\n            [\n              -116.16119384765625,\n              38.501967316378895\n            ],\n            [\n              -116.1536407470703,\n              38.425621828142184\n            ],\n            [\n              -116.103515625,\n              38.38795699631396\n            ],\n            [\n              -115.99708557128905,\n              38.36534867623901\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"2","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Ekren, E.

Hens and drakes, respectively, consumed 79.2 percent and 30.0 percent animal matter on nontilled wetlands and consumed 16.6 percent and 1.1 percent animal matter on tilled wetlands. Aquatic dipterans (primarily larval forms), snails, fairy shrimp, and earthworms accounted for 71 percent of the diet of hens on nontilled wetlands, while barnyard grass (<i>Echinochloa crusgalli</i>) seeds formed 71 percent of the diet of hens on tilled wetlands. Cereal grain seeds formed 84 percent of the diet of 10 hens feeding on cropland. The diet of hens was influenced by reproductive status. Animal foods were predominant during the laying period (77.1 percent) but were less important in the postlaying diet (28.9 percent). Invertebrates formed 83.9 percent of the diet of renesting hens, 61.0 percent were dipteran larvae and snails. High consumption of animal foods during egg formation presumably is related to invertebrates being superior to plants in providing certain nutrients required for production of viable eggs. Research findings suggest that food requirements of prairie-nesting pintails can be met most effectively by providing pairs access to shallow, nontilled wetland habitat subject to periodic drawdowns.</p>","language":"English","publisher":"Wiley","doi":"10.2307/3800870","usgsCitation":"Krapu, G., 1974, Foods of breeding pintails in North Dakota: Journal of Wildlife Management, v. 38, no.

In this study, the oldest Cretaceous, which is equivalent to the Woodbridge day Member of the Raritan Formation of New Jersey, occurs just above sea level at Garvies Point, Glen Cove, and in the Port Washington sand pits in northwestern Long Island, whereas sediments from near the base of the Fire Island well arc correlated with the South Amboy Fire Clay Member. The Magothy and Matawan combined in Long Island are about 1,500 ft (457 m) thick, whereas in New Jersey both units rarely exceed a thickness of 500 ft (152 m). Outcropping Cretaceous sediments in Block Island are equivalent to the South Amboy Fire Clay Member rather than the Magothy, as indicated in prior studies. Palynologic zonation of the Late Cretaceous is tentatively extended to Magothy and younger strata on the basis of the appearance and proliferation of the more advanced, angiosperm pollen forms. This study also provides a basis for extending the zonation and hence the correlation to the sediments of the Continental Shelf.</p>","language":"English","publisher":"U. S.

The unconformity is parallel to formation contacts in the younger metavolcanic rocks and crosscuts formation contacts in the older metasedimentary rocks. Locally, basal conglomerate with pebbles derived from the older metasedimentary rocks occurs just above the unconformity. The older metasedimentary rocks consist mostly of former marl, chert, and mudstone; they contain three generations of superposed structures. The younger metavolcanic rocks consist mostly of former andesite flows, tuff, and graywacke; these contain only the younger two generations of superposed structures.

K-Ar ages of the granodiorite, andesite porphyry, tungsten-bearing tactites, and altered granodiorite from the Getchell mine indicate that emplacement, alteration, and mineralization are all part of a magmatic-thermal episode which took place approximately 90 m.y. ago. </p>","language":"English","publisher":"SPEM","doi":"10.2113/gsecongeo.69.5.646","usgsCitation":"Silberman, M.L., Berger, B.R., and Koski, R.A., 1974, K-Ar Age Relations of Granodiorite Emplacement and Tungsten and Gold Mineralization near the Getchell Mine, Humboldt County, Nevada: Economic Geology, v. 69, p. 646-656, https://doi.org/10.2113/gsecongeo.69.5.646.","productDescription":"11 p.","startPage":"646","endPage":"656","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":374836,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","county":"Humboldt","otherGeospatial":"Osgood Mountains","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.92724609375,\n              40.094882122321145\n            ],\n            [\n              -117.103271484375,\n              40.094882122321145\n            ],\n            [\n              -117.103271484375,\n              41.393294288784865\n            ],\n            [\n              -117.92724609375,\n              41.393294288784865\n            ],\n            [\n              -117.92724609375,\n              40.094882122321145\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"69","noUsgsAuthors":false,"publicationDate":"1974-08-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Silberman, Miles L.","contributorId":23947,"corporation":false,"usgs":true,"family":"Silberman","given":"Miles","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":789195,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berger, B.
