The U. S. Geological Survey has begun a detailed evaluation of geologic environmental conditions in continental shelf regions in order to facilitate safe development of continental shelf resources. Investigations of geohazards in the northeastern Gulf of Alaska (Fig. 1) began in 1974 when 6500 km of high and medium resolution seismic reflection data were collected from the eastern gulf between Yakutat and Montague Island (Carlson, Bruns and Molnia, 1975; Von Huene and others, 1975). The first extensive sediment sampling program was begun in 1975 when approximately 400 samples of continental shelf sediments were collected from the same area of the gulf (Carlson and others, 1977b). A limited number of geotechnical measurements were made from these samples and samples collected by subsequent programs, however, systematic measurement of geotechnical properties was not started until the 1977 cruise of the NOAA ship DISCOVERER. Once unstable environments or \"geohazards\", such as slumps and slides, are delineated, geotechnical testing is an important means of quantifying such geologic processes and consequently furthering our understanding of them.
The purposes of this report are two-fold: (1) to report variations of physical properties in 1-2 meter gravity cores and (2) to recognize any variations in the areal distribution of these properties within and adjacent to an area of mass movement in the northeastern Gulf of Alaska.

Eruptions of that period repeatedly formed domes, large volumes of pumice, hot pyroclastic flows, and, during the last 2,500 years, lava flows. Some of this activity resulted in mudflows that extended tens of kilometers down the floors of valleys that head at the volcano. This report describes the nature of the phenomena and their threat to people and property; the accompanying maps show areas likely to be affected by future eruptions of Mount St. Helens. Explosive eruptions that produce large volumes of pumice affect large areas because winds can carry the lightweight material hundreds of kilometers from the volcano. Because of prevailing winds, the 180-degree sector east of the volcano will be affected most often and most severely by future eruptions of this kind. However, the pumice from any one eruption will fall in only a small part of that sector. Pyroclastic flows and mudflows also can affect areas far from the volcano, but the areas they affect are smaller because they follow valleys. Mudflows and possibly pyroclastic flows moving rapidly down Swift and Pine Creeks could displace water in Swift Reservoir, which could cause disastrous floods farther downvalley.","language":"ENGLISH","publisher":"U.S. Govt.

The district is the leading source of zinc in Colorado and one of the major base-metal mining districts in the State. As valued at the time of production, total output of zinc, silver, copper, lead, and gold through 1972 was about $328 million. About 90 percent of this total was produced after 1930. \r\n\r\nThe productive part of the district is an area of about 3 square miles (7.8 square kilometers) on the northeast side of the deep canyon of the Eagle River between the small towns of Gilman and Red Cliff. The ore deposits are principally replacement deposits in dolomites of Mississippian and Devonian age and in quartzite of Cambrian age. A few productive veins occur in Precambrian rocks. The replacement deposits crop out in the cliffs of the canyon wall and extend northeastward downdip beneath Battle Mountain, which is composed of a thick sequence of Pennsylvanian clastic rocks. The deposits were originally worked through several separate mines along the canyon wall, but since 1918, all deposits in dolomite rocks, except some small ones near Red Cliff, have been worked through the Eagle mine of the New Jersey Zinc Company at Gilman. \r\n\r\nThe Gilman district lies on the eastern flank of the huge anticline of the Sawatch Range, near the steeply plunging north end of the anticline. Sedimentary rocks on the flank of this part of the anticline dip homoclinally northeastward to a synclinal axis about 8 mi (miles) (13 km (kilometers> northeast of Gilman and then rise more steeply to the Gore fault at the edge of the Gore Range. The homocline is broken by only a few faults most of which have displacements of less than 100 ft (feet) (30 m (meters>. In contrast, the underlying Precambrian rocks are broken by numerous faults and shear zones related to the Homestake shear zone, a northeast-trending master shear zone several miles wide. Fractures and shear zones along the northwest side of the master zone extend beneath the Gilman district. \r\n\r\nThe Gilman district is at the northwestern edge of the northeast-trending Colorado mineral belt as defined by mineralized areas and bodies of intrusive porphyries. Neighboring mining districts in the mineral belt to the southeast of Gilman are the Kokomo lead-zinc district, 13 mi (21 km) distant; the Climax molybdenum district, 16 mi (26 km) distant; and the Leadville district, 20 mi (32 km) distant. These districts, as well as others farther away, are characterized by abundant intrusive rocks of Laramide and middle Tertiary ages and by complex faults systems.

The area lies within the Coronado National Forest and forms a belt around the north, east, and south sides of the Saguaro National Monument (fig. 1). A mineral resource survey was made of the area in 1977 by the U.S. Geological Survey and the U.S. Bureau of Mines. This study indicates that the potential for finding metallic or nonmetallic mineral deposits, petroleum or coal or geothermal energy in the study area is low. This appraisal is based on geologic and geochemical investigations and on examination of all mineralized prospects. A geologic map was made of the area and its immediate surrounding. Chemical and spectrographic analyses were made of 1.30 stream-sediment samples and of 143 rock samples. The locations of mining claims were compiled and samples from most of the claims were assayed. There has been no recorded mineral production from within the study area.
The geology of the Rincon Mountains is structurally complex. The core of the Rincon Mountains, lying mainly within the Saguaro National Monument, is underlain by igneous and metamorphic rocks chiefly of Precambrian and Tertiary ages. The study area lies on the flanks of the mountains in a terrain of sedimentary, metamorphic, and igneous rocks mainly of Precambrian through mid-Tertiary age. The rocks of this area are cut by many faults, with low-angle or bedding-parallel faults abundant. the distribution of these faulted rocks around the flanks of the Rincon Mountains is the result of a doming in the core area, the sliding of rock masses from the high part of the dome down its flanks, and to the effects of erosion.
The potential for economic metallic mineral deposits is considered low because the known areas of anomalous concentrations of metals are small and the concentration of metals weak and erratic. The surface signs of mineralization are largely restricted to 4 locales in which some prospects exist (fig. 1): (1) east of Colossal Cave, southwest or the Rincon Mountains, (2) north of Happy Valley, east of the mountains, (3) between Roble and Youtcy Canyons, northeast of the mountains, and (4) near Italian Trap north of the mountains. Very little primary sulfide mineralization is present and signs of alteration are restricted to narrow zones along faults and fractures. The geochemical anomalies are weak. The sites at which anomalous values of copper, molybdenum, or silver were obtained are mainly controlled by faults.
Nonmetallic mineral resources occur in deposits that are too small and too remote to be economically attractive. Sand and gravel deposits in the main drainages are similar to larger deposits that occur closer to nearby highways and cities. Limestone and marble present in some of the metamorphic rocks are too impure and too broken for use as dimension stone. Use of this marble as decorative rock is limited by remote markets. Limestone suitable for making cement is not likely to be found in large quantities within the Rincon wilderness study area. Closely spaced fractures in the granitic rocks makes them of little value for building stone.

The pattern of radiometric ages is complex, reflecting the complex geologic history of this area. Local and regional radiometric evidence suggests that the southern Brooks Range schist belt has, at least in part, undergone a late Precambrian metamorphism and that the parent sedimentary and igneous rocks for the metamorphic rocks dated as late Precambrian are at least this old (Precambrian Z). \r\n\r\nThis schist terrane experienced a major thermal event in mid-Cretaceous time, causing widespread resetting of nearly all K-Ar mica ages. A series of apparent ages intermediate between late Precambrian and mid-Cretaceous are interpreted as indicating varying amounts of partial argon loss from older rocks during the Cretaceous event. The schist belt is characterized by dominant metasediments and subordinate metabasites and metafelsites. Blueschists occur within the schist belt from the Chandalar quadrangle westward to the Baird Mountains quadrangle, but geologic evidence does not support the existence of a fossil subduction zone.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr78254","usgsCitation":"Turner, D.L., Forbes, R.B., and Mayfield, C., 1978, K-Ar geochronology of the Survey Pass, Ambler River and Eastern Baird Mountains quadrangles, southwestern Brooks Range, Alaska: U.S. Geological Survey Open-File Report 78-254, Report: 41 p.; 3 Plates: 30.18 × 22.68 inches or smaller, https://doi.org/10.3133/ofr78254.","productDescription":"Report: 41 p.; 3 Plates: 30.18 × 22.68 inches or smaller","costCenters":[],"links":[{"id":407878,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_14658.htm","linkFileType":{"id":5,"text":"html"}},{"id":140106,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1978/0254/report-thumb.jpg"},{"id":34647,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1978/0254/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":34646,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1978/0254/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":34645,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1978/0254/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":34648,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1978/0254/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"250000","country":"United States","state":"Alaska","otherGeospatial":"Survey Pass, Ambler River, and eastern Baird Mountains quadrangles","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -160.5,\n 67\n ],\n [\n -153,\n 67\n ],\n [\n -153,\n 68\n ],\n [\n -160.5,\n 68\n ],\n [\n -160.5,\n 67\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b4893","contributors":{"authors":[{"text":"Turner, Donald L.","contributorId":11604,"corporation":false,"usgs":true,"family":"Turner","given":"Donald","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":154981,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Forbes, R.

In this study we have synthesized the results of previous geologic, geophysical, geochemical, and hydrologic investigations of the Long Valley area to develop a generalized conceptual and mathematical model which describes the gross features of heat and fluid flow in the hydrothermal system. \r\n\r\nCenozoic volcanism in the Long Valley region began about 3.2 m.y. (million years) ago and has continued intermittently until the present time. The major event that resulted in the formation of the Long Valley caldera took place about 0.7 m.y. ago with the eruption of 600 km 3 or more of Bishop Tuff of Pleistocene age, a rhyolitic ash flow, and subsequent collapse of the roof of the magma chamber along one or more steeply inclined ring fractures. Subsequent intracaldera volcanism and uplift of the west-central part of the caldera floor formed a subcircular resurgent dome about 10 km in diameter surrounded by a moat containing rhyolitic, rhyodacitic, and basaltic rocks ranging in age from 0.5 to 0.05 m.y. \r\n\r\nOn the basis of gravity and seismic studies, we estimate an aver- age thickness of fill of 2.4 km above the precaldera granitic and metamorphic basement rocks. A continuous layer of densely welded Bishop Tuff overlies the basement rocks, with an average thickness of 1.4 km; the fill above the welded Bishop Tuff consists of intercalated volcanic flows and tuffs and fluvial and lacustrine deposits. Assuming the average grain density of the fill is between 2.45 and 2.65 g/cm 3 , we calculate the average bulk porosity of the total fill as from 0.11 to 0.21. Comparison of published values of porosity of the welded Bishop Tuff exposed southeast of the caldera with calculated values indicates average bulk porosity for the welded tuff (including fracture porosity) from 0.05 to 0.10. Because of its continuity and depth and the likelihood of significant fracture permeability in the more competent rocks such as the welded tuff, our model of the hydrothermal system assumes that the Bishop Tuff provides the principal hot-water reservoir. However, because very little direct information exists from drill holes below 300 m, this assumption must be considered tentative. \r\n\r\nLong Valley caldera is drained by the Owens River and several tributaries which flow into Lake Crowley in the southeast end of the caldera. Streamflow and springflow measurements for water years 1964-74 indicate a total inflow to Lake Crowley of about 10,900 L/s. In contrast, the total discharge of hot water from the hydrothermal reservoir is about 300 L/s. For modeling purposes, the ground-water system is considered as comprising a shallow subsystem in the fill above the densely welded Bishop Tuff containing relatively cold ground water, and a deep subsystem or hydrothermal reservoir in the welded tuff containing relatively hot ground water. Hydrologic, isotopic, and thermal data indicate that recharge to the hydrothermal reservoir occurs in the upper Owens River drainage basin along the western periphery of the caldera. Temperature profiles in a 2.11- km-deep test well drilled by private industry in the southeastern part of the caldera suggest that an additional flux of relatively cool ground water recharges the deep subsystem around the northeast rim. Flow in the shallow ground-water subsystem is neglected in the model except in recharge areas and along Hot Creek gorge, where approximately 80 percent of the hot-water discharge from the hydrothermal reservoir moves upward along faults toward springs in the gorge. \r\n\r\nHeat-flow data from the Long Valley region indicate that the resurgent dome overlies a residual magma chamber more circular in plan than the original magma chamber that supplied the Bishop Tuff","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/pp1044A","usgsCitation":"Sorey, M., Lewis, R.E., and Olmsted, F.H., 1978, The hydrothermal system of Long Valley Caldera, California: U.S. Geological Survey Professional Paper 1044, Report: 60 p.; 1 Plate: 34.00 x 25.00 inches, https://doi.org/10.3133/pp1044A.","productDescription":"Report: 60 p.; 1 Plate: 34.00 x 25.00 inches","costCenters":[],"links":[{"id":33842,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1044a/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":104540,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_4695.htm","linkFileType":{"id":5,"text":"html"},"description":"4695"},{"id":33841,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1044a/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":117933,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1044a/report-thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Long Valley Caldera","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -119.0969,\n 37.7778\n ],\n [\n -119.0969,\n 37.5\n ],\n [\n -118.635,\n 37.5\n ],\n [\n -118.635,\n 37.7778\n ],\n [\n -119.0969,\n 37.7778\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a86e4b07f02db64da25","contributors":{"authors":[{"text":"Sorey, M.L.","contributorId":73185,"corporation":false,"usgs":true,"family":"Sorey","given":"M.L.","affiliations":[],"preferred":false,"id":152712,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lewis, Robert Edward","contributorId":73595,"corporation":false,"usgs":true,"family":"Lewis","given":"Robert","email":"","middleInitial":"Edward","affiliations":[],"preferred":false,"id":152713,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olmsted, F.

The difficult of 'prospecting in drift-covered and saprolite-mantled terrains suggests that all such deposits probably have not been discovered.

This map shows the changes that have occurred in the location of the main channel of the river from 1936 to 1974. The map indicated that certain reaches of the river are subject to different rates of channel migration. Also shown is the boundary of the flood plain, which is mapped at the point of abrupt break in slope. This map documents the position of the river channel prior to any withdrawals of water or alteration of the flow characteristics of the white river that may occur in order to meet water requirements principally associated with the proposed oil-shale industry or other development in the area.
The channel locations were determined from aerial photographs taken at four different time periods for the following Federal agencies: In 1936, U.S. Soil Conservation Services; 1953, U.S. Corps of Engineers; 1965, U.S. Geological Survey; and in 1974, U.S. Bureau of Land Management. The 1936 delineation, which is actually based upon photographs that were taken in 1936 and 1937, was made by projection of the original photographs on a base map that was prepared from 1:24,000 scale topographic maps. The 1953, 1965, and 1974 delineations were produced from stereographic models. The 1965 delineation was compiled from photographs that were taken during 1962-65. The delineation is labeled as 1965 for simplicity, however, because the photographs for 1965 cover about 60 percent of the study read of the river, and because no changed were discernable in those areas of repetitive photographic coverage.

In a 400-square-mile area directly north and east of Johnstown, rainfall totals of 6 to 12 inches were measured in a six to eight-hour period. Flood peaks having recurrence intervals greater than 100 years were recorded at several sites, primarily in the Conemaugh River basin. Runoff rates were as high as 2,390 cubic feet per second per square mile, in a 5.86-square-mile drainage area in the Little Conemaugh River basin. The Conemaugh River at Seward, which drains 715 square miles, had a peak discharge of 161 cubic feet per second per square mile. The flood waters claimed at least 78 lives and caused total losses in excess of $300 million. Also, seven earthfill dams, used mainly for water supply in the Johnstown area, failed. This report describes the storm and the associated flooding. A tabulation of peak gage heights and discharges for the July 1977 flood and for the maximum flood previously known is included for 57 sites.

These maps show the distribution and abundance of gold and silver in heavy-mineral concentrates.
Stream-sediment and heavy-mineral concentrate samples were collected from active stream channels and locally, from the interface of streambeds with intermediate- to low-tide beaches. Most of the stream sediment is fine- to coarse-grained sand, with a clay-silt fraction in streams discharging from glaciers. Stream sediment samples were air dried and sieved through a 80-mesh (0.2 mm) sieve, and the minus-80 mesh fraction was saved for analysis. A split of each sample was analyzed for gold by a 10 gram atomic-absorption method (Ward and others, 1969). Another split was analyzed for 16 elements by a semiquantitative spectrographic method (Grimes and Marranzino, 1968).
The heavy-mineral concentrates were obtained by panning stream sediments in the field to remove most of the light minerals. The panned samples were sieved though a 20-mesh (0.8 mm) screen in the laboratory, and the minus-20 mesh fraction was further separated with bromoform (specific gravity: 2.86) to remove any remaining light-mineral grains. Magnetite and other strongly magnetic heavy minerals were removed from the heavy-mineral fraction by use of a hand magnet. The remaining sample was passed through a Frantz Isodynamic Separator1 and a nonmagnetic fraction was obtained at a setting of 0.6 amperes. A split of this fraction was pulverized and analyzed for 16 elements including gold and silver by semiquantitative spectrographic method used for analyzing the stream sediment. The remaining split of the nonmagnetic fraction was examined for its mineralogic composition using a binocular microscope and X-ray diffraction. The nonmagnetic concentrates primarily contain muscovite, sphene, zircon, apatite, rutile, and anatase. Ore minerals such as gold, scheelite, minium, and most sulfides are also found in this fraction.
Sample sites and gold and silver values (in parts per million) are indicated by symbols as defined in the histograms. The maps show two populations for gold in stream sediments and for gold and silver heavy mineral concentrates. One population consists of generally higher gold and silver values found in samples collected in the sedimentary terrane in the western half of the area. The other population consists of generally lower gold and silver values found in samples collected in areas of sheeted basalt dikes, pillow basalts, and sedimentary terrane in the eastern half of the area. The anomalous silver values found on Knight Island and Latouche Island are associated with chalcopyright- and pyrite-bearing rocks.

The 10-year low mean monthly discharge (MMQ10) for October, November, April, and May for the receiving stream has been used to establish the discharge rate for the treatment systems at the appropriate time of the year. To determine the MMQ10 for the receiving stream the monthly mean discharge first was estimated by using a technique developed by Riggs (1969). Once the monthly mean discharge was determined the MMQ10 of the ungaged stream was estimated by using a graphical correlation between the monthly mean discharge and the MMQ10 of at least three gaging stations near the waste-stabilization pond.The MMQ10 for these gaging stations were determined by a log-Pearson Type III frequency analysis.
\nThe MMQ10 was determined for Maple Creek at Valmy, Aliens Creek near Oakdale, North Branch Manitowoc River at Sherwood, East Fork Poplar River near Curtiss, and Yellow River at Barronette.

Snake River Plain, and potential volcanic hazards to the radioactive waste management complex, and other waste storage and reactor facilities at the Idaho National Engineering Laboratory, Idaho","docAbstract":"The Arco-Big Southern Butte area of the eastern Snake River Plain, Idaho, includes a volcanic rift zone and more than 70 Holocene and late Quaternary basalt volcanoes. The Arco volcanic rift zone extends southeast for 50 km from Arco to about 10 km southeast of Big Southern Butte. The rift zone is the locus of extensional faults, graben, fissure basaltic volcanic vents, several rhyolite domes at Big Southern Butte, and a ferrolatite volcano at Cedar Butte. Limited radiometric age data and geological field criteria suggest that all volcanism in the area is younger than 700,000 years; at least 67 separate basaltic eruptions are estimated to have occurred within the last 200,000 years. The average volcanic recurrence interval for the Arco-Big Southern Butte area is approximately one eruption per 3,000 years. \r\n\r\nRadioactive waste storage and reactor facilities at the Idaho National Engineering Laboratory may be subject to potential volcanic hazards. The geologic history and inferred past volcanic events in the Arco-Big Southern Butte area provide a basis for assessing the volcanic hazard. It is recommended that a radiometric age-dating study be performed on rocks in cored drill holes to provide a more precise estimate of the eruption recurrence interval for the region surrounding and including the Radioactive Waste Management Complex. It is also recommended that several geophysical monitoring systems (dry tilt and seismic) be installed to provide adequate warning of future volcanic eruptions.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr78691","usgsCitation":"Kuntz, M., and Kork, J.O., 1978, Geology of the Arco-Big Southern Butte area, eastern Snake River Plain, and potential volcanic hazards to the radioactive waste management complex, and other waste storage and reactor facilities at the Idaho National Engineering Laboratory, Idaho: U.S. Geological Survey Open-File Report 78-691, v, 70 p., https://doi.org/10.3133/ofr78691.","productDescription":"v, 70 p.","costCenters":[],"links":[{"id":393943,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_74923.htm"},{"id":37702,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1978/0691/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":144165,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1978/0691/report-thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Arco-Big Southern Butte area, eastern Snake River Plain","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -112.8139,\n 43\n ],\n [\n -112.3833,\n 43\n ],\n [\n -112.3833,\n 44.3069\n ],\n [\n -112.8139,\n 44.3069\n ],\n [\n -112.8139,\n 43\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db6833ff","contributors":{"authors":[{"text":"Kuntz, Mel A. 0000-0001-8828-5474","orcid":"https://orcid.org/0000-0001-8828-5474","contributorId":6446,"corporation":false,"usgs":true,"family":"Kuntz","given":"Mel A.","affiliations":[],"preferred":false,"id":160499,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kork, John O.","contributorId":20323,"corporation":false,"usgs":true,"family":"Kork","given":"John","email":"","middleInitial":"O.","affiliations":[],"preferred":false,"id":160500,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ]}
