These new data, together with earlier published radiometric ages, indicate a group of plutons about 70 to 85 m.y. old, a single body about 210 m.y. old, another that may be about 225 m.y. old, and several between 130 and 185 m.y. old. Evidence of intrusion is lacking in the intervals of about 90 to 130 m.y. and 185 to 200 m.y. The oldest age, about 226 m.y., may represent the chance preservation of a “primary” hornblende in a body in which the dark minerals are largely recrystallized and their radiometric ages reset. This age suggests that Triassic magmatism may be more widespread along the eastern margin of the Sierra Nevada batholith than had previously been considered.</p><p>The radiometric age data from the White Mountains, together with similar data from northwestern and north-central Nevada and abundant data from the central Sierra Nevada, suggest essentially continuous, albeit irregular, magmatic activity from Triassic to the end of Cretaceous, except for periods of little or no activity in earliest Jurassic and earliest Cretaceous. Episodes of magmatic activity may, and probably do, characterize specific areas, but when sufficiently large blocks of the Sierra Nevada batholith are considered, the sum of the episodes approaches a continuum.</p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1973)84<285:GROTWM>2.0.CO;2","usgsCitation":"Crowder, D.F., McKee, E.H., Ross, D.C., and

Holocene shallow-water hypersaline environments that have the&nbsp;potential to produce dolomite without deposition of more soluble&nbsp;evaporite minerals are found in Shark Bay, Australia, and on the Great&nbsp;Bahama Bank. These hypersalinity systems are characterized by&nbsp;near-vertical isosalinity layers of increasing concentration landward&nbsp;from the open ocean and show little or no relationship to bottom&nbsp;topography. I suggest that a similar but larger scale epicontinentalsalinity system covering the Late Cambrian and Early Ordovician&nbsp;carbonate continental shelf produced a broad wedge of subtidally&nbsp;deposited dolomite in the eastern half of the United States from&nbsp;Mexico to Canada. The distribution of limestone and dolomite in this&nbsp;region is closely keyed to the salinity gradient and accounts for the&nbsp;natural progression from a normal marine limestone facies through a&nbsp;transition zone to a highly saline dolomite facies phase.

The filling was episodic and complex. It involved 13 major periods of addition of lava to the crater, including spectacular lava falls as high as 100 m, and three major periods of draining of lava from the crater. Alae was nearly filled by August 3, 1969, largely drained during a violent ground-cracking event on August 4, 1969, and then filled to the low point on its rim on October 10, 1969. From August 1970 to May 1971, the crater acted as a reservoir for lava that entered through subsurface tubes leading from the vent fissure 150 m away. Another tube system drained the crater and carried lava as far as the sea, 11 km to the south. Much of the lava entered Alae by invading the lava lake beneath its crust and buoying the crust upward. This process, together with the overall complexity of the filling, results in a highly complicated lava lake that would doubtless be misinterpreted if found in the fossil record.</p></div></div><div id=\"cobranding-and-download-availability-text\" class=\"note test-pdf-link\"><br></div>","language":"English","publisher":"Springer","doi":"10.1007/BF02596984","issn":"0366483X","usgsCitation":"Swanson, D.A., Duffield, W.A., Jackson, D.B., and Peterson, D.W., 1972, The complex filling of alae crater, Kilauea Volcano, Hawaii: Bulletin Volcanologique, v. 36, no. 1, p. 105-126, https://doi.org/10.1007/BF02596984.","productDescription":"22 p.","startPage":"105","endPage":"126","costCenters":[],"links":[{"id":203374,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","otherGeospatial":"Kilauea Volcano","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -155.30616760253906,\n              19.38888634723281\n            ],\n            [\n              -155.2265167236328,\n              19.38888634723281\n            ],\n            [\n              -155.2265167236328,\n              19.447169246612997\n            ],\n            [\n              -155.30616760253906,\n              19.447169246612997\n            ],\n            [\n              -155.30616760253906,\n              19.38888634723281\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"36","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaae4b07f02db668b8b","contributors":{"authors":[{"text":"Swanson, D.

Food supply probably is still adequate for free-ranging nonbreeding birds, but could become limited if current land use trends continue.  Congregating condors on fewer and fewer acres could be detrimental in other ways.  It seems the needs of condors can best be met by maintaining a continuous band of :foraging country throughout the species' horseshoe-shaped range.  Public needs for open space and livestock agriculture can also be served by land use zoning, cooperative agreements, easements or other land controls implemented with consideration :for the condors' welfare.  Of immediate concern is the declining food situation in the general vicinity of the active condor nests in the Sespe-Piru region.  Reproduction is definitely depressed, and the reduced local food supply is the only apparent cause.  Predicted future developments can only worsen the situation.  A concerted effort should be made immediately to slow the loss of food and foraging area closest to the Sespe Condor Sanctuary including: (1) the Big Mountain-Newhall Ranch regions of southern Ventura County; (2) the arc of grassland around the southern and eastern boundaries of the Sespe Sanctuary; and (3) the Tejon Ranch.  Within these areas efforts should be made to increase the amount of condor food by: (1) increasing the amount of livestock, if compatible with proper land use; (2) modifying procedures for disposal of dead livestock, so that more are available to condors; (3) encouraging (subsidizing) ranchers to sacrifice livestock for condor food at certain times o:f the year; and (4) developing a state or Federal supplemental feeding program utilizing cattle, deer or other carrion regularly distributed at close, protected feeding sites.  If a convenient food supply is as important to reproduction as it appears, those nest sites closest to the best food source may become most productive and significant in the preservation of this species.  These sites, which are in the Piru Creek area, are outside the boundaries o:f the Sespe Condor Sanctuary, but are recognized by the U.S. Forest Service (1971) as extremely important to condor survival.  Protective measures recommended in the Forest Service plan should be implemented as soon as possible to preserve this area's usefulness as condor nesting habitat.  Food may not be the factor currently limiting condor reproduction.  However, the reproductive rate is inadequate to sustain the condor population for long.  As food shortage has been shown to limit breeding in many species (Lack 1954, 1966), and as it is something which can be manipulated, it is a logical factor for further study and experimentation.","language":"English","publisher":"Bureau of Sport Fisheries and Wildlife, Patuxent Wildlife Research Center","publisherLocation":"Laurel, Maryland","usgsCitation":"Wilbur, S., 1972, Food resources of the California condor: Administrative Report., 18.","productDescription":"18","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":202619,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae652","contributors":{"authors":[{"text":"Wilbur, S.R.","contributorId":53908,"corporation":false,"usgs":true,"family":"Wilbur","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":327515,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Individual reflecting horizons can be traced across the slope-basin boundary. The sense of offset along faults on the continental slope is predominantly, but not entirely, west side up. Two faults of small displacement are seen to be west-dipping reverse faults. Magnetic anomalies on the Juan de Fuca plate can be traced 40–100 km eastward under the slope, and structural interpretation combined with calculated rates of subduction suggests that approximately 50 km of the outer continental slope may have been formed in Pleistocene time. Rocks of Pleistocene age dredge from a ridge exposing acoustic “basement” on the slope, plus the results of deep-sea drilling off northern Oregon, are consistent with this interpretation. The question of whether or not subduction is occurring at present is unresolved because significant strain has not affected the upper 200 m of section in the Cascadia basin. However, deformation of the outer part of the slope has been episodic and may reflect episodic yield, deposition rate, subduction rate, or some combination of these factors.</p></div></div></div><ul id=\"issue-navigation\" class=\"issue-navigation u-margin-s-bottom u-bg-grey1\"></ul>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(72)90053-9","issn":"00253227","usgsCitation":"Silver, E.A., 1972, Pleistocene tectonic accretion of the continental slope off Washington: Marine Geology, v. 13, no. 4, p. 239-249, https://doi.org/10.1016/0025-3227(72)90053-9.","productDescription":"11 p.","startPage":"239","endPage":"249","costCenters":[],"links":[{"id":219428,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Washington","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -127.66113281249999,\n              45.644768217751924\n            ],\n            [\n              -121.2451171875,\n              45.644768217751924\n            ],\n            [\n              -121.2451171875,\n              48.545705491847464\n            ],\n            [\n              -127.66113281249999,\n              48.545705491847464\n            ],\n            [\n              -127.66113281249999,\n              45.644768217751924\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"13","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7c54e4b0c8380cd79919","contributors":{"authors":[{"text":"Silver, E.

Fresh ground water is mostly in unconsolidated deposits derived from the Coast Ranges on the west and the Sierra Nevada on the east.. The interfingering of Coast Range and Sierran alluvium, together with the variability and lenticularity of each, causes variation in the hydrologic properties both vertically and horizontally in San Joaquin Valley deposits. A persistent confining stratum, the Corcoran Clay Member of the Tulare Formation, can be correlated through most of the study area. Informally, the deposits above the clay are termed the upper units the clay is termed the confining clay stratums and the deposits from the bottom of the clay to the base of fresh water, where known, are termed the lower unit. The upper unit is composed of beds, lenses, and tongues of gravel, sand, and clay ranging in thickness from about 100 feet in the north to 500 feet at the south end of the study area. A distinctive white clay, at or near the base of the upper unit, can be traced across the center of the valley. The confining clay stratum is the greenish to bluish gray lacustrine Corcoran Clay Member of the Tulare Formation; it ranges from 0 to 130 feet in thickness. No attempt to delineate the top and bottom of the Tulare Formation was made because of the thickness and similarity of deposits overlying and underlying the Corcoran. The lower unit is lithologically similar to the upper unit and ranges in thickness, where the base of fresh water has been mapped, from 90 to more than 1,400 feet.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr73119","usgsCitation":"Hotchkiss, W.R., 1972, Generalized subsurface geology of the water-bearing deposits, northern San Joaquin Valley, California: U.S. Geological Survey Open-File Report 73-119, iv, 18 p., https://doi.org/10.3133/ofr73119.","productDescription":"iv, 18 p.","costCenters":[],"links":[{"id":84851,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1973/0119/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":162303,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1973/0119/report-thumb.jpg"},{"id":394221,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52127.htm"}],"country":"United States","state":"California","otherGeospatial":"northern San Joaquin Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.6083,\n              36.75\n            ],\n            [\n              -120.1056,\n              36.75\n            ],\n            [\n              -120.1056,\n              37.8711\n            ],\n            [\n              -121.6083,\n              37.8711\n            ],\n            [\n              -121.6083,\n              36.75\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6aec64","contributors":{"authors":[{"text":"Hotchkiss, W.

The watershed has an area of 1,479 square miles and is drained along its southwestern edge by the Minnesota River (Minnesota Division of Waters, 1959). The major watercourse within the watershed is Hawk Creek, having a drainage area of 510 square miles. Other, shorter streams drain into the Minnesota River but are mostly ephemeral. The watershed has a gently undulating land surface formed on glacial deposits. Directly underlying the glacial deposits in most of the area are Cretaceous sedimentary rocks. Paleozoic and Precambrian rocks are also locally in contact with overlying glacial deposits. Beds of sand and gravel buried at various depths within the glacial deposits are generally thin and discomtinuous but are the most accessible and widely used aquifers in the watershed. Beds of poorly consolidated sandstone in the Cretaceous rocks are locally good aquifers, generally yielding softer water, but in lesser quantities, than aquifers in the overlying glacial deposits. In the eastern part of the watershed, aquifers in Paleozoic and Precambrian sedimentary rocks are capable of high yields to wells and contain water of similar quality to water in the overlying Cretaceous and glacial deposits.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Washington, D.C.","doi":"10.3133/ha391","collaboration":"Prepared in cooperation

It borders the Pacific Ocean on the west and the Santa Cruz Mountains on the east. The city of Watsonville is the largest center of population.\r\n\r\nDeposits that range in age from Pliocene to Holocene make up the ground-water reservoir. These include, from oldest to youngest, the Purisima Formation, Aromas Red Sands of Allen (1946), terrace deposits, alluvium, and dune sand. These deposits underlie an area of about 80 square miles and have a maximum thickness of about 4,000 feet. The alluvium yields most of the water pumped from wells in the area.\r\n\r\nPre-Pliocene rocks underlie and form the boundaries of the ground-water reservoir. These rocks contain ground water in fractures and in sandstone beds. However, they are not an important source of ground water. There is close continuity between the geology of the Pajaro Valley area and that of the Soquel-Aptos area, which is contiguous on the north.\r\n\r\nGround water in the Pajaro Valley area is derived from three sources: (1) Precipitation within the Pajaro Valley area that reaches the ground-water body by direct infiltration or by seepage from streams, (2) seepage from the Pajaro River as it crosses the Pajaro Valley carrying runoff which originates upstream from the valley, and (3) precipitation in the Soquel-Aptos area that infiltrates and then moves southeastward at depth into the Pajaro Valley area.\r\n\r\nGround water in most wells in the Pajaro Valley area occurs under confined (artesian) conditions; the only exception is ground water in the upper, near-surface part of the alluvium and that in the dune sand. It moves south from the north part of the area and southwest away from the San Andreas fault toward and out under Monterey Bay. In the south part of the area, ground-water movement is almost due west. The San Andreas fault probably is the only fault that has a restrictive effect on the movement of ground water.\r\n\r\nWater levels in wells in the Pajaro Valley area in 1970 averaged about 2 feet lower than that in 1950. Ground-water pumpage averaged 46,100 acre-feet per year during the period 1963 through 1969.\r\n\r\nThere are two distinct ground-water quality zones in the Pajaro Valley area: a shallow, semiperched zone of poor-quality water and a deeper, confined zone of good quality-water. Also, sea-water intrusion has occurred in limited areas near the mouth of the Pajaro River and in the vicinity of McClusky Slough.\r\n\r\nThe channel of the Pajaro River near Aromas and the beds of streams that drain the area north and northeast of Watsonville have the greatest potential for artificial recharge by surface infiltration of water. The gravel at the base of the alluvium is the best zone for injection of water through wells.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr73199","usgsCitation":"Muir, K.S., 1972, Geology and ground water of the Pajaro Valley area, Santa Cruz and Monterey Counties, California: U.S. Geological Survey Open-File Report 73-199, Report: iv, 33 p.; 3 Plates: 33.53 × 21.22 inches or smaller, https://doi.org/10.3133/ofr73199.","productDescription":"Report: iv, 33 p.; 3 Plates: 33.53 × 21.22 inches or smaller","costCenters":[],"links":[{"id":388963,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_2298.htm"},{"id":84907,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1973/0199/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":170866,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1973/0199/report-thumb.jpg"},{"id":84910,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1973/0199/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":84908,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1973/0199/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":84909,"rank":402,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1973/0199/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","county":"Monterey County, Santa Cruz County","otherGeospatial":"Pajaro Valley area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -121.87408447265625,\n              36.81808022778526\n            ],\n            [\n              -121.6021728515625,\n              36.81808022778526\n            ],\n            [\n              -121.6021728515625,\n              37.0833\n            ],\n            [\n              -121.87408447265625,\n              37.0833\n            ],\n            [\n              -121.87408447265625,\n              36.81808022778526\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66cacf","contributors":{"authors":[{"text":"Muir, K.
