A mineral survey of the Sheep Mountain Wilderness study area and Cucamonga Wilderness area and additions by the U.S. Geological Survey and Bureau of Mines in 1975 covered about 66,500 acres (26,500 ha) of the San Bernardino and Angeles National Forests in southern California. The two study areas are separated by San Antonio Canyon. The mineral resource potential was evaluated through geological, geochemical, and geophysical studies by the Geological Survey and through evaluation of mines and prospects by the Bureau of Mines.

The site, which includes about 7.8 km 2, is highly accessible and is adjacent to a railroad. \r\n\r\nThe anticline is one of a series of northwest-trending salt anticlines lying along the northeast edge of the Paradox basin. These anticlines are cored by evaporites of the Paradox Member of the Hermosa Formation of Middle Pennsylvanian age. \r\n\r\nThe central core of the Salt Valley anticline forms a ridgelike mass of evaporites that has an estimated amplitude of 3,600 m. The evaporite core consists of about 87 percent halite rock, which includes some potash deposits; the remainder is black shale, silty dolomite, and anhydrite. The latter three lithologies are referred to as 'marker beds.' Using geophysical logs from drill holes on the anticline, it is possible to demonstrate that the marker beds are complexly folded and faulted. \r\n\r\nAvailable data concerning the geothermal gradient and heatflow at the site indicate that heat from emplaced wastes should be rapidly dissipated. \r\n\r\nPotentially exploitable resources of potash and petroleum are present at Salt Valley. Development of these resources may conflict with use of the site for waste emplacement.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77761","usgsCitation":"Hite, R.J., 1977, Subsurface geology of a potential waste emplacement site, Salt Valley Anticline, Grand County, Utah: U.S. Geological Survey Open-File Report 77-761, ii, 26 p. :ill., map ;27 cm., https://doi.org/10.3133/ofr77761.","productDescription":"ii, 26 p. :ill., map ;27 cm.","costCenters":[],"links":[{"id":141036,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0761/report-thumb.jpg"},{"id":37237,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0761/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699a1f","contributors":{"authors":[{"text":"Hite, R.

Data were collected to determine the possibility of subsurface injection of waste-treatment plant effluent. One exploratory hole, one test injection well, and eight observation wells were constructed between May 1973 and February 1976. The exploratory hole was drilled to a depth of 1,750 feet below land surface; the test injection well is open in dolomite between 952 and 1 ,040 feet; and the observation wells are open to intervals above , in, and below the test injection zone. The lithology of the upper 100 feet is predominantly clay. From 100 to 1,750 feet below land surface, limestone and dolomite predominate. Gypsum is present 1,210 feet below land surface. Laboratory analyses of cores taken during drilling are given for vertical intrinsic permeability, porosity, interval transit time, and compressibility. Specific capacities tested during drilling range from 4 to 2,500 gallons per minute per foot of drawdown. An 83-hour withdrawal test at 4,180 gallons per minute and a 2-month injection test at 650 gallons per minute were run. Small water-quality changes were observed in one observation well immediately above the test injection zone during and after the injection test. Formation water in all of the wells with the exception of the shallowest observation wells is saline. The vertical position of saltwater is estimated to be at about 280 feet below land surface. Thirteen wells within a 1-mile radius of the test site were located and sampled for water quality.

These studies were made as part of an intensive geophysical program aimed at defining the overall configuration of the liquid core and the attendant hydrothermal fluids. The results of the profiling studies were presented orally at the Annual Fall Meeting of the American Geophysical Union held in San Francisco, Calif., December 6, 1976. This report summarizes in more detail the techniques, results, and some conclusions related to the EM profiling studies. The complete results of an intensive VLF study made by L. A. Anderson (U.S. Geol. Survey, oral communication, 1976) will be presented in a separate report. Only a few of these results are discussed here.

Oxidizing, silica undersaturated, alkaline solutions are eluted through a column of rhyolitic glass shards at a carefully controlled temperature, pressure, and flow rate. The solutions are monitored for the concentration of uranium and selected additional elements (Si, K, Li, F), and the glass is recovered and examined for physical and/or chemical evidence of attack. The flushing mode is designed to mimic leaching of glass shards by intermittent, near-surface waters with which the glass is not in equilibrium. \r\n\r\nReported rates are applicable only to the experimental conditions (120?C, 7,000 psi), but it is assumed that the reaction mechanisms and the relative importance of rate-influencing parameters remain unchanged, at reduced temperature and pressure. Results of the above experiment indicate that silica and uranium are released from glass shards at comparable rates, while lithium and potassium are released faster and fluorine slower than either Si or U. Rates of release of silica and uranium correlate positively with the surface area of the shards. Rhyolitic shards release uranium at faster rates than rhyodacitic shards of comparable surface area. Changes in the shards resulting from experimental treatment and observed in the original glass separates from an Oligocene ash (compared to a Pleistocene ash) include; surface pitting, increased surface area, devitrification rinds (<1l micron wide) and reduced lithium contents. Future investigations will study the effect of temperature, pressure, solution composition, and flow rate on the relative mobility of U, Si, Li, F, and K.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr77744","usgsCitation":"Zielinski, R.A., 1977, Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass: U.S. Geological Survey Open-File Report 77-744, 36, [5] leaves of plates :ill. ;28 cm.; (41 p. - PGS), https://doi.org/10.3133/ofr77744.","productDescription":"36, [5] leaves of plates :ill. ;28 cm.; (41 p. - PGS)","costCenters":[],"links":[{"id":145048,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1977/0744/report-thumb.jpg"},{"id":39701,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0744/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a18e4b07f02db60541a","contributors":{"authors":[{"text":"Zielinski, Robert A. 0000-0002-4047-5129 rzielinski@usgs.gov","orcid":"https://orcid.org/0000-0002-4047-5129","contributorId":1593,"corporation":false,"usgs":true,"family":"Zielinski","given":"Robert","email":"rzielinski@usgs.gov","middleInitial":"A.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":163765,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":9795,"text":"ofr76724 - 1977 - Hydrologic data for North Creek, Trinity River basin, Texas, 1975","interactions":[],"lastModifiedDate":"2022-01-03T20:52:43.292044","indexId":"ofr76724","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1977","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"76-724","title":"Hydrologic data for North Creek, Trinity River basin, Texas, 1975","docAbstract":"This report contains the rainfall, runoff, and storage data collected during the 1975 water year for the 21.6-square-mile area above the stream-gaging station North Creek near Jacksboro, Texas. The weighted-mean rainfall in the study area during the water year was 39.01 inches, which is greater than the 18-year average of 30.21 inches for the period 1958-75. Monthly rainfall totals ranged from 1.04 inches in November to 7.94 inches in May. The mean discharge for 1975 at the stream-gaging station was 5.98 cfs, compared with the 14-year (1957-70) average of 5.75 cfs. The annual runoff from the basin above the stream-gaging station was 4,330 acre-feet or 3.76 inches. Three storms were selected for detailed computations for the 1975 water year. The storms occurred on Oct. 30-31, 1974, May 2, 1975 , and Aug. 26, 1975. Rainfall and discharge were computed on the basis of a refined time breakdown. Patterns of the storms are illustrated by hydrographs and mass curves. A summary of rainfall-runoff data is tabulated. There are five floodwater-retarding structures in the study area. These structures have a total capacity of 4,425 acre-feet below flood-spillway crests and regulate streamflow from 16.3 square miles, or 75 percent of the study area. A summary of the physical data at each of the floodwater-retarding structures is included. (Woodard-USGS)

At least 13 of these sources are known to contain high acidity and (or) trace-element concentrations or to contribute water to adversely affected streams. From January 1976 to March 1977, drainage from the Argo Tunnel in Idaho Springs--one of the major metal-mine drainage sources in the study area--exhibited variations in discharge from 0.35 to 0.55 cubic feet per second (0.010 to 0.016 cubic meters per second), a relatively constant temperature of 16 degrees Celsius, and variations in specific conductance from 2,680 to 3,410 micromhos per centimeter at 25 degrees Celsius (though a value of about 3,100 micromhos persisted throughout most of the period of record). High, but relatively constant, total concentrations (in micrograms per liter) of arsenic (100 to 180), cadmium (140 to 170), copper (5,000 to 6,000), iron (160,000 to 200,000), lead (less than 100 to 200), manganese (80,000 to 110,000), and zinc (40,000 to 49,000) were measured in the Argo Tunnel drainage from March 1976 to March 1977. Except for lead, the trace elements were mostly dissolved (82 percent or greater) and appear to represent baseline concentrations. Long-term degradation of water flowing from the Argo Tunnel is shown by increases of at least 2.5 to 8.0 times for dissolved solids, dissolved iron, calcium, magnesium, and sulfate since 1906. The acidity has changed from neutral in 1906 to a median pH value of 2.9 in 1976-77. Comparison of current Argo Tunnel data with those collected previously by other investigators indicates that spring chemical flushes containing higher than baseline trace-element concentrations occurred in 1973 and 1974, but not in 1975 or 1976, and probably not in 1972. The spring chemical flushes appear to be associated with increased infiltration from snowmelt in the catchment of the Argo Tunnel. Because of the wide ranges in mine-drainage quality and quantity expected for discharges from abandoned mines in the study area, each situation must be examined individually, and the management alternative chosen for mine-drainage abatement must be tailored to solve the particular mining and hydrologic problems at a given site.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Water and Related Land Resources Management Study","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"ENGLISH","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr77734","collaboration":"Prepared in cooperation with the U.S. Army Corps of Engineers Omaha District, Omaha, Nebraska","usgsCitation":"Wentz, D.A., 1977, Quantity and quality of drainage from the Argo Tunnel and other sources related to metal mining in Gilpin, Clear Creek and Park Counties, Colorado: U.S. Geological Survey Open-File Report 77-734, iv, 61 leaves :ill., maps; Volume V: Supporting Technical Reports Appendices; Appendix F: USGS Mine Drainage Study; 27 cm., https://doi.org/10.3133/ofr77734.","productDescription":"iv, 61 leaves :ill., maps; Volume V: Supporting Technical Reports Appendices; Appendix F: USGS Mine Drainage Study; 27 cm.","numberOfPages":"128","costCenters":[],"links":[{"id":144951,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_77_734.png"},{"id":254517,"rank":100,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1977/0734/ofr77-0734.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Colorado","county":"Gilpin County;Clear Creek County;Park County","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64adf5","contributors":{"authors":[{"text":"Wentz, Dennis A. dawentz@usgs.gov","contributorId":1838,"corporation":false,"usgs":true,"family":"Wentz","given":"Dennis","email":"dawentz@usgs.gov","middleInitial":"A.","affiliations":[{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"preferred":false,"id":163482,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":9949,"text":"ofr79688 - 1977 - Geohydrologic reconnaissance of Lake Mead National Recreation Area; Temple Bar to Grand Wash Cliffs, Arizona","interactions":[],"lastModifiedDate":"2023-03-06T23:49:15.444665","indexId":"ofr79688","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1977","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"79-688","title":"Geohydrologic reconnaissance of Lake Mead National Recreation Area; Temple Bar to Grand Wash Cliffs, Arizona","docAbstract":"The study is one of a series of geohydrologic reconnaissance studies being made in the Lake Mead National Recreation Area and covers about 200 square miles (520 square kilometers) from Temple Bar to the Grand Wash Cliffs. Streamflow in the drainages tributary to Lake Mead is meager and extremely variable. Ground water is derived from two principal sources: (1) infiltration into permeable rocks near Lake Mead and (2) ground-water underflow in the basins that drain to the lake.
The volume of ground water derived from Lake Mead is much greater than that derived from the basins. In terms of potential groundwater development the rocks saturated by lake water probably extend less than 1 mile (1.6 kilometers) from the lake, whereas the basins that contribute underflow to the lake are of much larger areal extent. The most favorable sites for ground-water development are Grapevine Mesa, Sandy Point, Hualapai Wash, and the area near and south of Temple Bar; the permeable rocks include the conglomerate facies of the Muddy Creek Formation, the older alluvium, and the Chemehuevi Formation. The least favorable areas for ground-water development are those underlain by the mudstone facies of the Muddy Creek Formation. Seven sites are recommended for future ground-water development. Five sites are within 1 mile (1.6 kilometers) of Lake Mead and two sites are between 3 and 5 miles (5 and 8 kilometers) from the lake.
The ground water contains less than 1, 500 milligrams per liter of dissolved solids in most of the area. Ground water on Grapevine Mesa contains less than 500 milligrams per liter of dissolved solids, and that from springs in the metamorphic and plutonic rocks contains more than 1, 500 milligrams per liter of dissolved solids.
