In eastern South Dakota, 0.5 million ha were enrolled in the CRP from 1985 to 1990 (Agric. Stabilization and Conserv. Serv., Brookings, S.D., unpubl. Data), which represents the largest change in conservation land-use practices in the region since the 1956 Soil Bank Program (Goetz 1987).</p><p>Although the CRP is anticipated to produce substantial benefits for some wildlife species, particularly ground-nesting birds, its significance to white-tailed deer (<i>Odocoileus virginianus</i>) in the northern Great Plains agricultural region is poorly understood. Higgins et al. (1987) speculated that proliferation of CRP grasslands may provide a missing habitat component in intensively managed farmland, thereby enhancing several species of wildlife, including white-tailed deer. Deer managers in the region have expressed concerns that improved cover associated with DRP plantings on private land could attract deer and reduce hunter success rates or lead to increased depredation of adjacent croplands or stored winter forages (L. Rice, S.D. Dep. Game, Fish, and Parks, Rapid City, pers. comm., 1989). Our objectives were to describe variation in deer use of CRP lands by season, diel period, and deer activity class as a means of assessing seasonal importance of CRP fields to white-tailed deer in agricultural Midwest.</p>","language":"English","publisher":"Wiley","usgsCitation":"Gould, J.H., and Jenkins, K.J., 1993, Seasonal use of conservation reserve program lands by white-tailed deer in

Both sets of data revealed a pronounced genetic discontinuity (along a broad path extending from south-eastern Mississippi to north-eastern Georgia) that corresponds to a recently recognized distinction between the nominal forms </span><i>G. affinis</i><span> to the west and </span><i>G. holbrooki</i><span>to the east. However, several populations from the general contact region exhibited unusual allelic associations in high frequency, suggestive of evolutionary processes within a zone of introgressive hybridization. These involve: (i) cytonuclear profiles representing combinations of nuclear and mitochondrial genotypes that tended to be more nearly species-specific and concordant elsewhere; and (ii) significant nuclear gametic disequilibria, perhaps attributable to positive assortative mating and/or differential fitnesses of homospecific vs. recombinant genotypes. However, outside this suspected hybrid region, ‘heterospecific’ genetic markers also appeared in low frequency, thus complicating interpretations. These discordant alleles on a broader geographic scale may reflect: (a) the retention of polymorphisms from an ancestral gene pool; (b) occasional evolutionary convergence (especially with respect to electrophoretic mobility of allozyme alleles); (c) the ‘footprints’ of a moving hybrid zone; or (d) differential introgressive penetrance across the current hybrid region.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-294X.1993.tb00103.x","usgsCitation":"Scribner, K.T., and Avise, J.C., 1993, Cytonuclear genetic architecture in mosquitofish populations and the possible roles of introgressive hybridization: Molecular Ecology, v. 2, no. 3, p. 139-149, https://doi.org/10.1111/j.1365-294X.1993.tb00103.x.","productDescription":"11 p.","startPage":"139","endPage":"149","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":479507,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/1zz768mc","text":"External Repository"},{"id":337128,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"3","noUsgsAuthors":false,"publicationDate":"2008-04-14","publicationStatus":"PW","scienceBaseUri":"58c12664e4b014cc3a3d3531","contributors":{"authors":[{"text":"Scribner, Kim T.","contributorId":146113,"corporation":false,"usgs":false,"family":"Scribner","given":"Kim","email":"","middleInitial":"T.","affiliations":[{"id":135,"text":"Biological Resources Division","active":false,"usgs":true},{"id":16582,"text":"Department of Fisheries and Wildlife and Department of Zoology, 480 Wilson Rd. 13 Natural Resources Building, Michigan State University, East Lansing, MI 48824","active":true,"usgs":false}],"preferred":false,"id":681444,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Avise, John C.","contributorId":182338,"corporation":false,"usgs":false,"family":"Avise","given":"John","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":681445,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Correlation of the two sequences remains somewhat equivocal, although on the basis of biostratigraphy and a reversed magnetic interval both appear to have been deposited during the early to middle Campanian. Sedimentary structures suggest that the northern sequence was deposited by turbidity currents in a continental rise setting, whereas the southern sequence primarily reflects deposition in shelf and slope environments . Right-lateral offset on the San Andreas and subsidiary faults to the east of the Pigeon Point Formation can account for 100's of km of northward transport since its deposition. However, Champion and others (1984) suggested 2500 km of northward transport from a tropical setting of about 21°N.

At most localities, the thrust places Ordovician rocks above Permian and Pennsylvanian rocks, although near its southeastern extent, it ramps laterally downsection to the southeast. At its southeasternmost exposures, Cambrian rocks are juxtaposed above Mississippian rocks. New work indicates that the hanging wall of the Putnam thrust contains three imbricate thrust slices or subplates, which are, from structurally lowest to highest (and generally from north to south), the Lone Pine subplate, the Narrows subplate, and the Bear Canyon-Toponce subplate.</p><p>The steeply south-dipping, east-trending Narrows thrust overlies the Lone Pine subplate, underlies the Narrows subplate, and is a lateral ramp that merges eastward into the Putnam thrust. Where exposed, the Narrows thrust places Late Proterozoic quartzite of the Brigham Group over Ordovician and Cambrian rocks. The Bear Canyon thrust overlies the Narrows subplate and underlies the Bear Canyon-Toponce subplate, dips eastward along the west side of the Portneuf Range, and places lower Brigham Group quartzite above Cambrian limestone and Cambrian and Late Proterozoic upper Brigham Group quartzite and argillite. At its northern extent, the Bear Canyon thrust curves to the east, where it merges with the Putnam thrust. On the east side of the range, the intensely folded Toponce thrust places upper Brigham Group quartzite above Ordovician rocks; the Toponce is believed to be an eastward extension of the Bear Canyon thrust.</p><p>East-dipping rocks within the Lone Pine subplate were not strongly deformed during Cretaceous thrusting, in contrast to rocks within the Narrows subplate, where east-vergent recumbent folds, cleavage directions that fan about northerly strikes, and tectonic thickening and thinning of beds indicate intense, thrust-parallel shear. The deformation and thrust geometry within the Narrows subplate suggest that the Narrows subplate actually consists of several horses within a foreland-dipping duplex.</p><p>Late Miocene and younger basin deposits occur in north-trending valleys adjacent t o the northern Portneuf Range and, to the west, the Bannock and Pocatello ranges. At most places, the Neogene deposits dip to the east by as much as 35°, indicating that late Miocene and younger extension and down-to-the-east rotation occurred along mostly west-dipping listric faults that are inferred to merge on at least one regional detachment. Although range-bounding faults account for a large component of extension and rotation, an additional large component was contributed by numerous, relatively small-displacement normal faults within mountain ranges.</p>","language":"English","publisher":"GSA","doi":"10.1130/MEM179-p95","usgsCitation":"Kellogg, K.S., 1992, Chapter 4: Cretaceous thrusting and Neogene block rotation in the northern Portneuf Range region, southeastern Idaho: Memoir of the Geological Society of America, v. 179, p. 95-113, https://doi.org/10.1130/MEM179-p95.","productDescription":"19 p.","startPage":"95","endPage":"113","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":371219,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Southeastern Idaho","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -113.44482421875,\n              42.309815415686664\n            ],\n            [\n              -111.6650390625,\n              42.309815415686664\n            ],\n            [\n              -111.6650390625,\n              44.15068115978094\n            ],\n            [\n              -113.44482421875,\n              44.15068115978094\n            ],\n            [\n              -113.44482421875,\n              42.309815415686664\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"179","noUsgsAuthors":false,"publicationDate":"1992-01-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Kellogg, Karl S. 0000-0002-6536-9066 kkellogg@usgs.gov","orcid":"https://orcid.org/0000-0002-6536-9066","contributorId":1206,"corporation":false,"usgs":true,"family":"Kellogg","given":"Karl","email":"kkellogg@usgs.gov","middleInitial":"S.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":779398,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The key variables in the model are bulk properties such as porosity, uranium content of the rock, emanating efficiency, and rock density, all of which are measurable. Thus, the model is simplified by the averaging effects of a macroscopic view of the system. Although less rigorous than other models presented in the literature, it is more generally applicable to natural systems because it does not rely on microscopic properties of the system, which are impossible to quantify.

Lerbekmo and Campbell (1969) narrowed the source of the ash to an area northeast of the Mt. Bona-Mt. Churchill massif in the St. Elias Mountains of southern Alaska. Based on indirect evidence, Lerbekmo and Campbell (1969) further suggested that the vent was beneath the Klutlan Glacier, adjacent to a mound of coarse pumice, 16 km northeast of Mt. Bona. Recently discovered pumice and ash deposits and a possible vent structure near the summit of Mt. Churchill suggest an alternate source area. The White River Ash is a bilobate plinian fallout deposit covering more than 340,000 km<sup>2</sup> and containing an estimated 25-50 km<sup>3</sup> of tephra (Bostock, 1952; Berger, 1960; fig. 1).

Overall, tufted puffins consumed (by weight) 41% sandlance (Ammodytes hexapterus), 22% capelin (Mallotus villosus), 19% walleye pollock (Theragra chalcogramma), 13% other fish, and 5% invertebrates, whereas horned puffins took 85% sandlance, 4% capelin, 2% pollock, 8% other fish, and <1 % invertebrates. All of the pollock consumed were young of the year, whereas 4 year-classes of capelin were present, from young of the year through spawning adults. Puffins took mostly first-year sandlance, but fish in their second year or older were also common at colonies near Kodiak, Alaska. The importance of juvenile pollock in the diet of tufted puffins varied geographically from little or no use in the north-central Gulf and Kodiak areas to moderate use (5 to 20%) in the Semidi and Shumagin Islands to heavy use (25 to 75%) in the Sandman Reefs and eastern Aleutians. An estimated 11 billion pollock were consumed by tufted puffins throughout the region in 1986. The proportion of pollock in puffin diets at the Semidi Islands was strongly correlated with independent estimates of cohort strength in 3 years. Puffins may thus provide a useful index of distribution and year class abundance of first-year pollock, a species that currently supports an important commercial fishery in the Gulf of Alaska.","language":"English","publisher":"Inter-Research Science Publisher","doi":"10.3354/meps080001","usgsCitation":"Hatch, S., and Sanger, G.A., 1992, Puffins as samplers of juvenile pollock and other forage fish in the Gulf of Alaska: Marine Ecology Progress Series, v. 80, p. 1-14, https://doi.org/10.3354/meps080001.","productDescription":"14 p.","startPage":"1","endPage":"14","numberOfPages":"14","costCenters":[{"id":106,"text":"Alaska Biological Science Center","active":false,"usgs":true}],"links":[{"id":488001,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3354/meps080001","text":"Publisher Index Page"},{"id":259710,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Gulf Of Alaska","volume":"80","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a9020e4b0c8380cd7fb4d","contributors":{"authors":[{"text":"Hatch, Scott","contributorId":16268,"corporation":false,"usgs":true,"family":"Hatch","given":"Scott","affiliations":[],"preferred":false,"id":355628,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sanger, Gerald A.","contributorId":10660,"corporation":false,"usgs":true,"family":"Sanger","given":"Gerald","email":"","middleInitial":"A.","affiliations":[{"id":6654,"text":"USFWS","active":true,"usgs":false}],"preferred":false,"id":355627,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

DDE concentrations were significantly different among locations. Median DDE concentrations did not decline significantly in eggs from Glenn L. Martin National Wildlife Refuge, Maryland, between 1973 and 1986. The median DDE residue for eggs from Martin Refuge in 1986 surpassed the value associated with 10% eggshell thinning, but was below the value associated with production of 1.0 young per active nest, a level assumed to represent a stable population. DDD, DDT, dieldrin, PCB, and mercury residues in all eggs appeared insignificant with regard to potential effects on shell thickness or reproduction. DDE and PCB residues were lower in eggs collected in 1986-87 than in those collected in the 1970s for each area. DDD, DDT, and dieldrin were not detected in Martin Refuge eggs in 1986, representing a significant reduction since 1973. DDD, DDT, and dieldrin levels in Massachusetts and Virginia eggs in 1986-87 were similar to those in eggs from the 1970s for each state. Mercury residues in eggs from Martin Refuge may be increasing and although not significant in this study, may warrant future monitoring.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Raptor Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Audet, D., Scott, D., and Wiemeyer, S.N., 1992, Organochlorines and mercury in osprey eggs from the eastern United States: Journal of Raptor Research, v. 26, no. 4, p. 219-224.","productDescription":"219-224","startPage":"219","endPage":"224","numberOfPages":"6","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":195954,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":16370,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://elibrary.unm.edu/sora/jrr/v026n04/p00219-p00224.pdf","linkFileType":{"id":1,"text":"pdf"}}],"volume":"26","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae5e4b07f02db68a756","contributors":{"authors":[{"text":"Audet, D.

Very large volumes of basaltic magma were generated and partly erupted before substantial lithospheric extension began. Volcanism continued, along with extension and deep rift subsidence, for the ensuing 15 m.y. Much of the basaltic magma, including some of the earliest flows, was formed by partial melting of isotopically primitive asthenosphere contained in the plume head. The intense but relatively short duration of rifting and magmatism is a result of the dissipation of thermal and mechanical energy in the plume head. As the plume head spread beneath the lithosphere, it stretched the overlying lithosphere radially away from the Lake Superior region, the triple junction of the rift system, and partially melted to form the great volume of basalt and related intrusive rocks of the region.</span></p><p><span>The plume arrived beneath a continent that was under compression as a result of the ongoing Grenville orogeny that affected a large region east of the rift.

Although it can be semiquantitatively extended back into the late 1700's, the historical record is too short to recognize long-term patterns of lake-level behavior. To extend the historical record, information must be obtained from the Great Lakes geologic record. Such information includes the elevation and age of geomorphic features and stratigraphic sequences.</span></p><p><span>One of the longest geologic records of late Holocene lake-level variation is preserved in a beach-ridge complex along the southern shore of Lake Michigan called the Toleston Beach. This strandplain contains over 150 beach ridges that arc across northwestern Indiana and fan out into northeastern Illinois. Each ridge was formed during the fall from a high lake level, and the elevation of the foreshore deposits in each ridge provides information on the upper physical limit of lake level over the past 4000 years. Three scales of quasi-periodic lake-level variation were determined by radiocarbon-dating basal peats of wetlands between the ridges and by measuring the elevation of foreshore (swash) deposits within ridges. These three scales are: (1) a short-term and small-scale fluctuation of 25 to 35 years with a range of about 0.5 to 0.6 m; (2) an intermediate-term and meso-scale fluctuation of 140 to 160 years and a range of about 0.8 to 0.9 m; and (3) a long-term and large-scale fluctuation of 500 to 600 years and a range of 1.8 to 3.7 m. The short-term and intermediate-term fluctuations are reflected in the historical record.</span></p><p><span>An increase in the rate of shoreline progradation from east to west across Indiana's shoreline causes differential preservation of the lake-level fluctuations. That is, groups of four to six ridges in the western part of the strandplain that formed in response to the small-scale fluctuations combine eastward into single ridges and groups of ridges representing the meso-scale fluctuations. The large-scale fluctuations produced the most dramatic response in the western part of the Toleston Beach. Here, following each high stand, individual spits prograded southward off of a bedrock headland. The successive spit extensions created several small lakes landward of the spits and started the 20 km eastward stream-mouth deflection of the Grand Calumet River across Indiana's western lakeshore.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0037-0738(92)90048-V","issn":"00370738","usgsCitation":"Thompson, T., 1992, Beach-ridge development and lake-level variation in southern Lake Michigan: Sedimentary Geology, v. 80, no. 3-4, p. 305-318, https://doi.org/10.1016/0037-0738(92)90048-V.","productDescription":"14 p.","startPage":"305","endPage":"318","costCenters":[],"links":[{"id":224539,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Indiana","otherGeospatial":"southern Lake Michigan","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -87.7770599367265,\n              41.975677013046834\n            ],\n            [\n              -87.7770599367265,\n              41.56719135170678\n            ],\n            [\n              -86.98171551883281,\n              41.56719135170678\n            ],\n            [\n              -86.98171551883281,\n              41.975677013046834\n            ],\n            [\n              -87.7770599367265,\n              41.975677013046834\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"80","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f032e4b0c8380cd4a646","contributors":{"authors":[{"text":"Thompson, T.A.","contributorId":73226,"corporation":false,"usgs":true,"family":"Thompson","given":"T.A.","email":"","affiliations":[],"preferred":false,"id":375953,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We know little about the 1836 event, but the 1868 event had a surface rupture extending 41 km along the southern Hayward fault. Right-lateral surface slip occurred in 1868, but was not well measured. Witness accounts suggest coseismic right slip and afterslip of under a meter. We measured the spatial variation of the historic creep rate along the Hayward fault, deriving rates mainly from surveys of offset cultural features, (curbs, fences, and buildings). Creep occurs along at least 69 km of the fault's 82-km length (13 km is underwater). Creep rate seems nearly constant over many decades with short-term variations. The creep rate mostly ranges from 3.5 to 6.5 mm/yr, varying systemically along strike. The fastest creep is along a 4-km section near the south end. Here creep has been about 9mm/yr since 1921, and possibly since the 1868 event as indicated by offset railroad track rebuilt in 1869. This 9mm/yr slip rate may approach the long-term or deep slip rate related to the strain buildup that produces large earthquakes, a hypothesis supported by geoloic studies (Lienkaemper and Borchardt, 1992). If so, the potential for slip in large earthquakes which originate below the surficial creeping zone, may now be 1/1m along the southern (1868) segment and &ge;1.4m along the northern (1836?) segment. Substracting surface creep rates from a long-term slip rate of 9mm/yr gives present potential for surface slip in large earthquakes of up to 0.8m. Our earthquake potential model which accounts for historic creep rate, microseismicity distribution, and geodetic data, suggests that enough strain may now be available for large magnitude earthquakes (magnitude 6.8 in the northern (1836?) segment, 6.7 in the southern (1868) segment, and 7.0 for both). Thus despite surficial creep, the fault may be ready for the recurrence of large earthquakes today. However, the timing (Williams, 1992) and size of future events may vary greatly due to uncertainties in the tectonophysical model assumed for the Hayward fault within the greater San Andreas fault system (Lisowski and Savage, 1992).</p>","largerWorkType":{"id":24,"text":"Conference Paper"},"largerWorkTitle":"Proceedings of the second conference on earthquake hazards in the eastern San Francisco

The Cretaceous rocks of the aquifer system are separated from the pre-Cretaceous rocks by an unconformity that spans about 60 million years of erosion during the Jurassic Period. The upper surface of the pre-Cretaceous rock complex forms the base of the Edwards-Trinity aquifer system. The configuration of the base reflects the original topography of the eroded pre-Cretaceous land surface plus the effects of subsequent deformation.</p>\n<p>The most permeable pre-Cretaceous rocks are in the eastern half of the study area where they compose the Hickory aquifer (in Upper Cambrian rocks), Ellenburger-San Saba aquifer (Upper Cambrian- Lower Ordovician), and Marble Falls aquifer (Lower Pennsylvanian). These aquifers are hydraulically connected to the northeastern fringe of the Edwards-Trinity aquifer system, as their up-turned margins crop out around the flanks of the breached Llano uplift. The Rustler aquifer in rocks of Late Permian age underlies parts of the Trans-Pecos region, where it yields small amounts of greatly mineralized water for industrial and agricultural purposes. The Dockum aquifer in rocks of Late Triassic age directly underlies the Edwards-Trinity aquifer system in western parts of the study area, and locally increases the saturated thickness of the ground-water-flow system by an average of about 200 feet. Despite these notable exceptions, the collective effect of the pre-Cretaceous rocks is that 01 a barrier to ground-water flow, which limits the exchange of water across the base of the Edwards-Trinity aquifer system.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri914071","usgsCitation":"Barker, R.A., and Ardis, A.F., 1992, Configuration of the base of the Edwards-Trinity aquifer system and hydrogeology of the underlying pre-Cretaceous rocks, west-central Texas: U.S. Geological Survey Water-Resources Investigations Report 91-4071, Document: v, 25 p.; Plate: 38.5 x 26.5 inches, https://doi.org/10.3133/wri914071.","productDescription":"Document: v, 25 p.; Plate: 38.5 x 26.5 inches","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":326543,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri914071.JPG"},{"id":8706,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri91-4071/","linkFileType":{"id":5,"text":"html"}},{"id":8707,"rank":2,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/wri91-4071/pdf/wri91-4071-pl1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Texas","otherGeospatial":"Edwards-Trinity aquifer system","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4affe4b07f02db697c66","contributors":{"authors":[{"text":"Barker, Rene A.","contributorId":82669,"corporation":false,"usgs":true,"family":"Barker","given":"Rene","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":195737,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ardis, Ann F.","contributorId":96672,"corporation":false,"usgs":true,"family":"Ardis","given":"Ann","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":195738,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Surface geology is generally well \ndefined, but subsurface geology is poorly defined below about \n500 feet. Rocks that underlie the plain form the framework for a \nregional ground-water system that supplies large quantities of \nwater for irrigation and makes the plain nationally important in \nterms of agricultural production.\nThe 15,600-square-mile Snake River Plain is a grabenlike \nstructure that formed in middle Miocene time. The graben may \nhave been formed by oblique extensional forces resulting from \ninteractions between the North American and Pacific tectonic \nplates. The oldest known rocks underlying the plain, penetrated \nin a 14,007-foot-deep test hole northwest of Boise, are of middle \nMiocene age. Miocene volcanic rocks at the plain's margin that \ndip toward and underlie the plain were highly faulted and se- \nverely eroded before the plain was formed.\nFaults along the margins of the eastern part of the plain are \nnot visible at land surface and have been defined chiefly by geo- \nphysical methods. However, well-defined fault systems bound \nthe western part of the plain.\nThe eastern plain is underlain predominantly by Quaternary \nbasalt of the Snake River Group, which is intercalated with \nsedimentary rocks along the margins. Basalt crops out or is less \nthan 10 feet below land surface in the central part of the east- \nern plain and is usually less than 100 feet below land surface \nelsewhere. Geophysical data and drillers' logs indicate that \nQuaternary basalt in the central part of the eastern plain is as \nmuch as 5,000 feet thick. A test hole about 10 miles northeast \nof the Snake River near Wendell provided the first information \nabout deep subsurface stratigraphic relations in that part of the \nplain. The stratigraphic sequence penetrated in the test hole is \nsimilar to that in the north wall of the Snake River canyon be- \ntween Milner and King Hill. In that area, basalt of the Snake \nRiver Group thins toward the river and is underlain by sedi- \nmentary rocks and basalt of the Tertiary and Quaternary Idaho \nGroup.\nThe western plain is underlain mainly by unconsolidated and \nweakly consolidated Tertiary and Quaternary sedimentary rocks \nas much as 5,000 feet thick. Basalt also is present in the west- \nern plain and is most extensive near Mountain Home.\nQuaternary basalt of the Snake River Group, which composes \nmuch of the Snake River Plain regional aquifer system, is highly \ntransmissive. In the eastern plain, a thick sequence of thin- \nlayered basalt flows yields large volumes of water to wells. Wells \nopen to less than 100 feet of the aquifer yield as much as 7,000 \ngallons per minute; yields of 2,000 to 3,000 gallons per minute \nwith only a few feet of drawdown are common. Transmissivity\ncommonly exceeds 100,000 feet squared per day and, in places, 1 \nmillion feet squared per day.\nLarge springs in the Snake River canyon between Milner and \nKing Hill issue at the contact between highly transmissive pil- \nlow lava and less transmissive underlying rocks. In 1980, \nground-water discharge between Milner and King Hill, largely \nspring flow, averaged about 6,000 cubic feet per second.\nIn the western plain, coarse-grained sedimentary deposits are \nthickest and transmissivity is highest along the northern mar- \ngins. The percentage of coarse-grained sedimentary deposits de- \ncreases to the southwest, where lacustrine sedimentary deposits \npredominate.\nIn most of the eastern plain, the upper part of the ground- \nwater system is unconfined. At depth and in much of the west- \nern plain, aquifers are confined.\nAcross most of the plain, Quaternary basalt aquifers overlie \naquifers in the Tertiary Idavada Volcanics and Banbury Basalt \nof the Idaho Group. The older volcanic rocks are typically much \nless transmissive than the Quaternary basalt. Faults and frac- \ntures are permeable zones for water storage and conduits for \nwater movement. In places near the margins of the plain, the \nIdavada Volcanics contains important geothermal aquifers.","language":"English","publisher":"U.S. Government Printing Office","doi":"10.3133/pp1408B","usgsCitation":"Whitehead, R., 1992, Geohydrologic framework of the Snake River plain regional aquifer system, Idaho and eastern Oregon: U.S. Geological Survey Professional Paper 1408, Report: vi, 32 p.; 6 Plates: 37.02 x 20.13 and smaller, https://doi.org/10.3133/pp1408B.","productDescription":"Report: vi, 32 p.; 6 Plates: 37.02 x 20.13 and smaller","numberOfPages":"39","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":97417,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408b/plate-1.pdf","size":"5843","linkFileType":{"id":1,"text":"pdf"}},{"id":97419,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408b/plate-3.pdf","size":"2682","linkFileType":{"id":1,"text":"pdf"}},{"id":97420,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408b/plate-4.pdf","size":"1247","linkFileType":{"id":1,"text":"pdf"}},{"id":97421,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408b/plate-5.pdf","size":"1137","linkFileType":{"id":1,"text":"pdf"}},{"id":97422,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408b/plate-6.pdf","size":"2015","linkFileType":{"id":1,"text":"pdf"}},{"id":97418,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408b/plate-2.pdf","size":"1929","linkFileType":{"id":1,"text":"pdf"}},{"id":120451,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1408b/report-thumb.jpg"},{"id":67662,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1408b/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Idaho;Oregon","otherGeospatial":"Snake River Plain","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.0,42.0 ], [ -111.0,45.0 ], [ -117.0,45.0 ], [ -117.0,42.0 ], [ -111.0,42.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1be4b07f02db6a8eab","contributors":{"authors":[{"text":"Whitehead, R.L.","contributorId":34891,"corporation":false,"usgs":true,"family":"Whitehead","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":222162,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

On a regional scale, most water moves horizontally through \ninterflow zones in Quaternary basalt of the Snake River Group. \nIn recharge and discharge areas, water also moves vertically \nalong joints and interfingering edges of basalt flows. Aquifer \nthickness is largely unknown, but geophysical studies suggest \nthat locally the Quaternary basalt may exceed several thousand \nfeet. Along the margins of the plain, sand and gravel several \nhundred feet thick transmit large volumes of water.\nRegional ground-water movement is generally from northeast \nto southwest, from areas of recharge to areas of discharge. Re- \ncharge is from seepage of surface water used for irrigation, \nstream and canal losses, underflow from tributary drainage ba- \nsins, and infiltration of precipitation. Aquifer discharge is largely \nspring flow to the Snake River and water pumped for irrigation. \nMajor springs are near American Falls Reservoir and along the \nSnake River from Milner Dam to King Hill.\nRegional ground-water flow was simulated with numerical \nmodels. Initially, a two-dimensional steady-state model that in- \ncluded a nonlinear, least-squares regression technique was used \nto estimate aquifer properties. Later, a three-dimensional steady- \nstate and transient model was used to replace the two-dimen- \nsional model. Three-dimensional model results indicated that \naverage total transmissivity ranged from about 0.05 to 120 feet \nsquared per second and vertical leakance ranged from about \n3 x 10<sup>-10</sup> to 5 x 10<sup>-6</sup> feet per second per foot of aquifer thickness.\nThe three-dimensional transient model was used to compare \nmeasured and estimated long-term changes in ground-water dis- \ncharge and water levels with simulated values. Initial head con- \nditions used in transient simulations were derived from a \nsteady-state solution of estimated preirrigation hydrologic condi- \ntions. Transient simulations were 5-year stress periods beginning \nin 1891 and ending in 1980. Recharge for each stress period from \n1926 to 1980 was estimated from surface-water irrigation, pre- \ncipitation, and streamflow records. Recharge for stress periods \nfrom 1891 to 1925 was based on the average value for stress peri- \nods from 1926 to 1980 and was indexed to estimated irrigated \nacreages. Average annual tributary drainage-basin underflow for \nstress periods from 1891 to 1910 was calculated by using basin- \nyield equations. Underflow for stress periods from 1911 to 1980 \nwas varied by use of streamflow records.\nTransient simulations reasonably approximated measured \nchanges in aquifer head and ground-water discharge that re- \nsulted from use of surface water for irrigation. Irrigation with \nsurface water peaked in about 1950; subsequent increases in irri- \ngation have been supplied largely by ground water. The three-\ndimensional model simulated water-level declines and reduced \nground-water discharge caused in part by increases in ground- \nwater pumping.\nThe transient model was used to simulate aquifer changes \nfrom 1981 to 2010 in response to three hypothetical development \nalternatives: (1) Continuation of 1980 hydrologic conditions, (2) \nincreased pumpage, and (3) increased recharge. Simulation of \ncontinued 1980 hydrologic conditions for 30 years indicated that \nhead declines of 2 to 8 feet might be expected in the central part \nof the plain. The magnitude of simulated head declines was con- \nsistent with head declines measured during the 1980 water year. \nLarger declines were calculated along model boundaries, but \nthese changes may have resulted from underestimation of tribu- \ntary drainage-basin underflow and inadequate aquifer definition. \nSimulation of increased ground-water pumpage (an additional \n2,400 cubic feet per second) for 30 years indicated head declines \nof 10 to 50 feet in the central part of the plain. These relatively \nlarge head declines were accompanied by increased simulated \nriver leakage of 50 percent and decreased spring discharge of 20 \npercent. The effect of increased recharge (800 cubic feet per sec- \nond) for 30 years was a rise in simulated heads of 0 to 5 feet in \nthe central part of the plain.","language":"English","publisher":"U.S. Government Printing Office","doi":"10.3133/pp1408F","usgsCitation":"Garabedian, S., 1992, Hydrology and digital simulation of the regional aquifer system, eastern Snake River Plain, Idaho: U.S. Geological Survey Professional Paper 1408, Report: vii, 102 p.; 10 Plates: 34.00 x 17.50 and smaller, https://doi.org/10.3133/pp1408F.","productDescription":"Report: vii, 102 p.; 10 Plates: 34.00 x 17.50 and smaller","numberOfPages":"112","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":104633,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_4858.htm","linkFileType":{"id":5,"text":"html"},"description":"4858"},{"id":119227,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1408f/report-thumb.jpg"},{"id":64931,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-01.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64932,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-02.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64933,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-03.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64934,"rank":403,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-04.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64935,"rank":404,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-05.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64936,"rank":405,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-06.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64937,"rank":406,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-07.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64938,"rank":407,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-08.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64939,"rank":408,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-09.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64940,"rank":409,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1408f/plate-10.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":64941,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1408f/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Idaho;Oregon","otherGeospatial":"Snake River Plain","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.0,42.0 ], [ -117.0,45.0 ], [ -111.0,45.0 ], [ -111.0,42.0 ], [ -117.0,42.0 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67e90a","contributors":{"authors":[{"text":"Garabedian, S.
