Data were collected to (1) document the water-quality characteristics of streams and impoundments in the Coteau area, (2) predict the impact of proposed impoundments, (3) define the amount of dissolved and suspended material transported, and (4) determine the differences in water quality between the impoundment inflows and outflows.</p>\n<p>Streamflow and water-quality data were collected at 12 stream and four impoundment sites. Continuous-record gages, set to collect data at 15-minute intervals, and readings taken by local observers were used to complete discharge records at 10 stream sites and stage records at three impoundment sites. Automatic samplers and local observers collected storm runoff, sediment, and nutrient samples at 10 stream sites. Water-quality samples were collected at various time and stage intervals during high flow and periodically during low flow. Primary emphasis in the stream-sampling program was on analysis of samples for nutrients in 1980-82, and on analysis of suspended sediment and nutrients in 1983-84. Field measurements were made of pH, water temperature, dissolved oxygen, specific conductance, alkalinity, and bacteria. Secondary emphasis was on analysis of major dissolved substances. Primary emphasis in the impoundments was on analysis of samples for phosphorus and chlorophyll and on the measurement of transparency. Temperature and dissolved-oxygen concentrations were measured to determine the degree of stratification.</p>\n<p>All data collected during the study are given in tables 4-13 of this report. The tables list mean-daily stream discharge, mean-daily suspendedsediment concentration, daily suspended-sediment discharge, results of waterquality analyses, and bed-material particle-size analyses at stream sites. The tables also list information on pool stage, water temperature, and transparency, on dissolved-oxygen, chlorophyll a, phytoplankton, and nutrient concentrations, and on chemical and partical-size analyses of bed material at impoundment sites.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"St. Paul, MN","doi":"10.3133/ofr8884","collaboration":"Prepared in cooperation with the U.S. Army Corps of Engineers, U.S. Soil Conservation Service","usgsCitation":"Smith, C., Payne, G.A., and Tornes, L., 1990, Hydrologic and water-quality data for streams and impoundments in the Coteau des Prairies-Upper Minnesota River basin, 1979-84: U.S. Geological Survey Open-File Report 88-84, vii, 46 p., https://doi.org/10.3133/ofr8884.","productDescription":"vii, 46 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":392,"text":"Minnesota Water Science Center","active":true,"usgs":true}],"links":[{"id":154108,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1988/0084/report-thumb.jpg"},{"id":50535,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1988/0084/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Minnesota","otherGeospatial":"Coteau des Prairies-Upper Minnesota River basin","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db611718","contributors":{"authors":[{"text":"Smith, C.J.","contributorId":69141,"corporation":false,"usgs":true,"family":"Smith","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":183560,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Payne, G.

Ground water flows through a network of interconnected secondary openings; primary porosity is virtually nonexistent. Some of these openings have been enlarged by solution. Secondary porosity and permeability exhibit great spatial variability, and the yield and specific capacity of wells are highly variable. The number of water-bearing zones decreases with depth. Fifty percent of water-bearing zones are encountered within 100 feet of the land surface, and 81 percent are within 200 feet.\r\n\r\n      Most ground-water flow in the Valley Creek basin is local and discharges to nearby streams. Ground-water discharge comprised an average of 76 percent of the flow of Valley Creek during 1983--87, including both natural ground- water discharge and quarry pumpage discharged to Valley Creek. Discharge from the Cedar Hollow quarry comprised 21 to 26 percent of the base flow of Valley Creek; the average was 23 percent. The average natural base flow of Valley Creek would be 8 percent lower if the quarry were not operating.\r\n\r\n      Regional ground-water flow is to the northeast to the Schuylkill River. On the western side of the Valley Creek basin, the ground-water divide is 1/2 mile west of the surface-water divide. An estimated 0.75 million gallons per day of ground water flows from the adjacent West Valley Creek basn eastward into the Valley Creek basin. A ground-water divide is not present on the eastern side of the basin; the water table slopes gently eastward toward the Schuylkill River. On the northeaster side, an estimated 1.76 million gallons per day of ground water flows northeastward out of the basin to the Schuylkill River beneath the surface-water divide. On the southeaster side, an estimated 0.85 million gallons per day of ground water flows beneath the surface-water divide into the basin.\r\n\r\n      Annual water budgets and an average water budget were calculated for 1983-87 for the 20.8-square-mile area bove the streamflow-gaging station. Annual precipitation for 1983-87 ranged from 40.61 to 56.55 inches and averaged 47.25 inches; annual streamflow ranged from 15.55 to 28.57 inches and averaged 22.31 inches; annual evapotranspiration ranged from 18.21 to 24.83 inches and averaged 22.90 inches; and annual recharge ranged from 15.89 to 26.84 inches and averaged 21.04 inches.\r\n\r\n      The Valley Creek basin was modeled as a two-dimensional water-table aquifer. Recharge to, ground-water flow through, and discharge from the rocks of Chester valley were simulated. In order to include the natural hydrologic boundaries of the ground-water-flwo system, the 66.4-square-mile area between the Brandywine Creek and the Schuylkill River was modeled. The model was calibrated under stead-state conditions using avareage recharge and evapotranspiration rates. Aquifer hydraulic conductivity was estimated from specific-capacity and quifer-test data. The average (1983-87) annual water budget for hte Valley Creek basin was simualted.\r\n\r\n      The effect of increased ground-water development on base flow and underflow was simulated by locating a hypothetical well field produceing 4 million gallons per day in different parts of the basin. Pumpage from a well field near surface-water divides would induce as much as an additional 1.41 inches per year of underflow from an adjacent surface-water basin. Pumpage from a well field near the center of the basin would affect base flow more than underflow.\r\n\r\n      Increased seepage of ground water into quarries as a result of their expansion was simulated as increased withdrawal by pumping. A 100-percent increase in the pumping rate of the Cedar Hollow quarry, from 3.93 to 7.86 million gallons per day, owuld reduce the natural base flow of Valley Creek by 18 percent. However, the quarry pumpage would be discharged to Valley Creek, thereby increasing the base flow at the gaging station by ","language":"English","publisher":"U.S. Geological

In addition, abundant features of unknown and nonseismic origin are present. Geologic criteria for interpreting an earthquake origin in these areas are illustrated in practical applications; these criteria can be used to determine the origin of liquefaction features in many other geographic and geologic settings. \r\n\r\nIn both coastal South Carolina and the New Madrid seismic zone, the earthquake-induced liquefaction features generally originated in clean sand deposits that contain no or few intercalated silt or clay-rich strata. The local geologic setting is a major influence on both development and surface expression of sand blows. Major factors controlling sand-blow formation include the thickness and physical properties of the deposits above the source sands, and these relationships are illustrated by comparing sand blows found in coastal South Carolina (in marine deposits) with sand blows found in the New Madrid seismic zone (in fluvial deposits). In coastal South Carolina, the surface stratum is typically a thin (about 1 m) soil that is weakly cemented with humate, and the sand blows are expressed as craters surrounded by a thin sheet of sand; in the New Madrid seismic zone the surface stratum generally is a clay-rich deposit ranging in thickness from 2 to 10 m, in which case sand blows characteristically are expressed as sand mounded above the original ground surface. \r\n\r\nRecognition of the various features described in this paper, and identification of the most probable origin for each, provides a set of important tools for understanding paleoseismicity in areas such as the Central and Eastern United States where faults are not exposed for study and strong seismic activity is infrequent.","language":"ENGLISH","doi":"10.3133/pp1504","usgsCitation":"Obermeier, S., Jacobson, R., Smoot, J.P., Weems, R., Gohn, G.S., Monroe, J., and Powars, D., 1990, Earthquake-induced liquefaction features in the coastal setting of South Carolina and in the fluvial setting of the New Madrid seismic zone: U.S. Geological Survey Professional Paper 1504, 44 p.; 1 plate in pocket, https://doi.org/10.3133/pp1504.","productDescription":"44 p.; 1 plate in pocket","costCenters":[],"links":[{"id":125080,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1504/report-thumb.jpg"},{"id":67205,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1504/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":67206,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1504/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a51e4b07f02db629737","contributors":{"authors":[{"text":"Obermeier, S.

May 2, 1983, a magnitude (ML) 6.7 earthquake occurred about 12 km northeast of the town of Coalinga, approximately halfway between Los Angeles and San Francisco. The shock was felt from Los Angeles to 200 km north of Sacramento and as far east as Las Vegas. Unlike other well-documented, major earthquakes in California in the 20th century, this event was not associated with any previously known or suspected active fault.

The volcano is a superb outdoor laboratory for studying volcanic processes, deposits of observed events, and deposits whose origins are inferred by classic geologic techniques, including analogy to recent deposits. During the past 4,500 years, Mount St. Helens has been more active and more explosive than any other volcano in the conterminous United States. \r\nMount St. Helens became active in mid-March 1980, and eruptive activity began on March 27. Since the climactic eruption of May 18, 1980, the volcano has continued to be active at least until 1988. The 1890 activity of Mount St. Helens is summarized in U.S. Geological Survey Professional Papers 1249 and 1250. \r\n\r\nThis road guide is a tour of Mount St. Helens volcano and vicinity, with emphasis on the effects and deposits of the 1980 eruption. The road log starts from the U.S. Geological Survey's David A. Johnston Cascades Volcano Observatory, Vancouver, Washington. The guide is organized around two primary routes. LEG I is on paved and gravel roads from Vancouver to areas east of Mount St. Helens, including Windy Ridge Overlook near Spirit Lake. This is possibly the most scenic route described in the guide, including a transect of the devastated zone of May 18, 1980, Spirit Lake, and numerous vistas of the volcano. LEG II leads to areas west of the volcano from Vancouver via U.S. Interstate Highway 5, then on a paved ... road along the Toutle River. Highlights include the spectacular effects of mudflows and a view of the huge debris-avalanche deposit that was formed on May 18, 1980.","language":"ENGLISH","publisher":"U.S. G.P.O. ; For sale by the Books and Open-File Reports Section, U.S. Geological Survey,","doi":"10.3133/b1859","usgsCitation":"Doukas, M.P., 1990, Road guide to volcanic deposits of Mount St. Helens and vicinity, Washington: U.S. Geological Survey Bulletin 1859, v, 53 p. :ill. ;28 cm., https://doi.org/10.3133/b1859.","productDescription":"v, 53 p. :ill. ;28 cm.","costCenters":[],"links":[{"id":3390,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://vulcan.wr.usgs.gov/Volcanoes/MSH/NatMonument/RoadGuide/framework.html","linkFileType":{"id":5,"text":"html"}},{"id":166237,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/bul/1859/report-thumb.jpg"},{"id":62160,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/bul/1859/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0fe4b07f02db5fed5e","contributors":{"authors":[{"text":"Doukas, Michael P. mdoukas@usgs.gov","contributorId":2686,"corporation":false,"usgs":true,"family":"Doukas","given":"Michael","email":"mdoukas@usgs.gov","middleInitial":"P.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":212683,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Ground-water withdrawals from the aquifer in 1981 were estimated to be 4.8 million gallons per day, of which about 90 percent was withdrawn in Ottawa County. Wells drilled at the beginning of the 20th century originally flowed at the land surface, but in 1981 water levels ranged from 22 to 471 feet below land surface. A large cone of depression has formed as a result of ground water withdrawals near Miami. Wells completed in the Roubidoux aquifer have yields that range from about 100 to more than 1,000 gallons per minute.\r\nAn aquifer test and a digital ground-water flow model were used to estimate aquifer and confining-layer hydraulic characteristics. Using these methods, the transmissivity of the aquifer was estimated to be within a range of 400 to 700 square feet per day. The leakance of the confining layer was determined to be within a range from 0 to 0.13 per day, with a best estimate value in a range from 4.3 x 10-8 to 7.7 x 10-8 per day.\r\n\r\nAnalyses of water samples collected as part of this study and of water-quality data from earlier work indicate that a large areal change in major-ion chemistry occurs in ground water in the Roubidoux aquifer in northeastern Oklahoma. The ground water in the easternmost part of the study unit has relatively small dissolved-solids concentrations (less than 200 milligrams per liter) with calcium, magnesium, and bicarbonate as the major ions. Ground water in the westernmost part of the study unit has relatively large dissolved-solids concentrations (greater than 800 milligrams per liter) with sodium and chloride as the major ions. A transition zone of intermediate sodium, chloride, and dissolved-solids concentrations exists between the easternmost and westernmost parts of the study unit.\r\n\r\nThree water-quality problems are apparent in the Roubidoux aquifer in northeast Oklahoma: (1) Contamination by mine water, (2) large concentrations of sodium and chloride, and (3) large radium-226 concentrations.\r\n\r\nMany wells in the mining area have been affected by mine-water contamination. At present (1990), all instances of ground-water contamination by mine water can be explained by faulty seals or leaky casings in wells that pass through the zone of mine workings and down to the Roubidoux aquifer. None of the data available to date demonstrate that mine water has migrated from the Boone Formation through the pores and fractures of the intervening geologic units to the Roubidoux aquifer.\r\n\r\nGround water with large concentrations of sodium and chloride occurs at some depth throughout the study unit. In the eastern part of the study unit, chloride concentrations greater than 250 milligrams per liter are found at depths greater than approximately 1,200 to 1,500 feet. Data are too few to determine the depth to ground water with large concentrations of sodium and chloride in the southern and southwestern parts of the study unit.\r\n\r\nLarge concentrations of gross-alpha radioactivity in ground water occur near the western edge of the transition zone. Generally, ground water with large concentrations of gross-alpha radioactivity was found to exceed the maximum contaminant level for radium-226.\r\n\r\n(available as photostat copy

The aquifer is present throughout Iowa and is confined beneath other aquifers in much of the State. Information on the aquifer available from drillers and contractors, provided estimates of aquifer transmissivity values ranging from about 500 to about 3,000 square feet per day. The largest transmissivity values are for dolomite and dolomite-cemented sandstone, indicating that permeability in much of the aquifer is due to secondary fractures. The aquifer is vertically bounded by an upper leaky confining unit with a vertical hydraulic conductivity of 10<sup>-10</sup> feet per second.</p>\n<p>The aquifer was simulated using a two-layer finite-difference ground-water flow model. The upper layer simulated a source bed in aquifers composed of Silurian and Devonian rocks overlying the St. Peter-Jordan aquifer. The lower layer simulated flow in the St. Peter-Jordan aquifer. Lateral boundaries assigned in the model include constant heads in northeastern Iowa, where the aquifer is in contact with the Mississippi River or is unconfined, and no-flow boundaries in western and northwestern Iowa, where the rocks are insufficiently permeable to form an aquifer. The aquifer boundaries to the north, east, and south of Iowa were determined by geohydrologic conditions and the relation of the St. Peter-Jordan aquifer with the lateral extent of adjacent aquifers.</p>\n<p>An assumption that the largest part of recharge to the aquifer is from outcrop areas in northeastern Iowa and from Minnesota is not supported by the results of this study. Vertical leakage from overlying rocks accounted for most of the recharge to the aquifer in northwestern Iowa. Discharge is mostly through lateral boundaries and to rivers.</p>\n<p>Pumping has caused changes in the flow system that include regional declines in the potentiometric surface of the aquifer. Simulation indicates that pumping through 1980 increased net vertical leakage into the aquifer to about double the predevelopment rate. Discharge across lateral boundaries has been substantially reduced or reversed by pumping. Aquifer storage provided about one-third of the water required to supply pumping in the 1970's. Simulation of future conditions, assuming no increase in pumping rates, indicates that the rate of decline in water levels will decrease by the year 2020. As equilibrium with pumping is approached in 2020, 75 percent of the pumpage will be balanced by vertical leakage, eight percent by water released from aquifer storage, and 17 percent by increases in boundary recharge or decreases in boundary discharge. Future pumping at an increasing rate of about 10 percent per decade of the average pumping rate in 1975 will require about one and one-half times the vertical leakage of the 1971-1980 period and about fivetimes the net inflow from lateral boundaries; however, the rate of water released from aquifer storage will be about half the 1970's rate. Under these conditions, the head in the aquifer will continue to decline at an almost constant rate until 2020.</p>","language":"English","publisher":"U.S. Geological

It is the fourth largest terminal lake in the world, covering about 2,300 square miles in 1986. Since its historic low elevation of 4,191.35 feet in 1963, the lake rose to a new historic high elevation of 4,211.85 feet in 1986. Most of this increase (12.2 feet) occurred after 1982. The rise has caused $285 million of damage to lakeside industries, transportation, farming, and wildlife. Accompanying the rapid rise in lake level has been a decrease in salinity-from 28 percent in 1963 to about 6 percent in 1986. This has resulted in changes in the biota of the lake from obligate halophiles to opportunistic forms, such as blue-green algae and, most recently, a brackish-water fish.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Washington, D.C.","doi":"10.3133/wsp2332","usgsCitation":"Arnow, T., and Stephens, D.W., 1990, Hydrologic characteristics of the Great Salt Lake, Utah: 1847-1986: U.S. Geological Survey Water Supply Paper 2332, Report: v, 32 p.; 1 Plate: 38.94 in x 50.82 in, https://doi.org/10.3133/wsp2332.","productDescription":"Report: v, 32 p.; 1 Plate: 38.94 in x 50.82 in","numberOfPages":"40","costCenters":[{"id":610,"text":"Utah Water Science Center","active":true,"usgs":true}],"links":[{"id":395409,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_25364.htm"},{"id":246957,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wsp/2332/plate-1.pdf","size":"15001","linkFileType":{"id":1,"text":"pdf"}},{"id":25495,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wsp/2332/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":137524,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wsp/2332/report-thumb.jpg"}],"country":"United States","state":"Utah","otherGeospatial":"Great Salt Lake","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -113.104248046875,\n              40.6306300839918\n            ],\n            [\n              -111.8353271484375,\n              40.6306300839918\n            ],\n            [\n              -111.8353271484375,\n              41.74262728637672\n            ],\n            [\n              -113.104248046875,\n              41.74262728637672\n            ],\n            [\n              -113.104248046875,\n              40.6306300839918\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a28e4b07f02db61167b","contributors":{"authors":[{"text":"Arnow, Ted","contributorId":84733,"corporation":false,"usgs":true,"family":"Arnow","given":"Ted","affiliations":[],"preferred":false,"id":142920,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stephens, Doyle W.","contributorId":40195,"corporation":false,"usgs":true,"family":"Stephens","given":"Doyle","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":142919,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The existence of a categorically stable attractor characterizing both types of activities strongly suggests that the excitation mechanism of tremor is similar to that of gas piston events, which in turn are correlated with visual observations at the volcanic vent. Low values derived for the dimension of the attractor in phase space points to significant self-organization in the process of generation of tremor and offers general constraints on the dimensionality of attractors derived from models of acoustic emission associated with magma flow, vesiculation, and degassing. -from Authors</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/91JB00772","issn":"01480227","usgsCitation":"Chouet, B., and Shaw, H.R., 1990, Fractal properties of tremor and gas piston events observed at Kilauea Volcano, Hawaii: Journal of Geophysical Research, v. 96, no.

Projection of the reconstructed channel west to the Central Valley and east to the range crest, together with several assumptions about the position of the hinge line and changes in channel gradient, allows estimates of the amount of uplift at the range crest during the past 10 m.y. At Tioga Pass, this amounts to as much as 1,830 m, as compared to the 2,150 m estimated in an earlier study for Deadman Pass at the San Joaquin River 30 km to the south. Comparison of the geometry of these river systems leads to the conclusion that 10 m.y. ago an ancestral range of hills occupied the present site of the Sierran crest, and, although of relatively moderate relief, it was a barrier to westward drainage even before late Cenozoic uplift. At that time, the San Joaquin River was apparently the only river flowing westward across the range from well south of Mount Whitney north to Sonora Pass. The Tuolumne River evidently never extended east of this range. Comparison of the ancient channel with the modern channel of the Tuolumne River permits analysis of the later evolution of the river system and the development of Hetch Hetchy Valley and the Grand Canyon of the Tuolumne. At Rancheria Mountain, where the volcanic \"dam\" in the ancient channel was highest, the river was forced to shift laterally southward around the dam and adjacent to the volcanic infilling, and start its new channel in granitic bedrock. Near Rancheria Mountain, as much as 1,525 m of new channel incision has taken place in the past 10 m.y., and the modern channel is about 915 m lower than the abandoned channel. An undetermined amount of this downcutting was from glacial erosion. The Tuolumne river system provides no direct evidence for timing the onset of uplift, but the shape of the lO-m.y.-old channel at Rancheria Mountain suggests that uplift had been underway for some time before the volcanic infilling. This timing is compatible with evidence from the upper San Joaquin River. Hetch Hetchy Valley on the Tuolumne is a much \"fresher\" glaciated valley than is Yosemite Valley. Hetch Hetchy was filled to the brim with glacial ice as recently as 15,000-20,000 yr ago (Tioga glaciation), whereas Yosemite Valley probably has not been filled for 750,000 yr or more (Sherwin glaciation). Thus the upper reaches of Yosemite Valley cliffs have been shaped by spalling rather than by glacial scour and are much more irregular than those in Hetch Hetchy. </p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1990)102<0102:TLCEOT>2.3.CO;2","usgsCitation":"Huber, N., 1990, The late Cenozoic evolution of the Tuolumne River, central Sierra Nevada, California : GSA Bulletin, v. 102, no. 1, p. 102-115, https://doi.org/10.1130/0016-7606(1990)102<0102:TLCEOT>2.3.CO;2.","productDescription":"14 p.","startPage":"102","endPage":"115","costCenters":[],"links":[{"id":369383,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Sierra Nevadas","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -120.00,\n             38.00\n            ],\n            [\n              -119.00,\n              38.00\n            ],\n            [\n              -119.00,\n              37.30\n            ],\n            [\n              -120.00,\n              37.30\n            ],\n            [\n              -120.00,\n              38.00\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"102","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Huber, N.K.","contributorId":73610,"corporation":false,"usgs":true,"family":"Huber","given":"N.K.","affiliations":[],"preferred":false,"id":775701,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
