Eight partial sections of the Browns Park Formation of Miocene age were measured in Moffat County, northwestern Colorado, during the 1980 field season, as part of a study of the stratigraphy and depositional environments of the formation. These newly measured sections are intended to complement other surface sections of the Browns Park Formation measured (Hansen, 1965) to the west in Uintah County, Utah, and measured (Buffler, 1967) or diagrammed (Kucera, 1968) to the east in, respectively, Routt and Rio Blanco Counties, Colorado.
\nRock samples collected, indicated parenthetically by 80-SL prefixes, are shown in the section descriptions purely for reference purposes; petrographic and analytical results will be reported in later publications. Color names with numbers are based on comparison with the rock-color chart by Goddard and others (1948).
\nField investigations were supported by the National Uranium Resource Evaluation (NUKE) program of the Grand Junction Office, U. S. Department of Energy, under contract No. DE-A113-78GJ01686.

We used intensive post-earthquake interview surveys to gather objective reports both of instances of unusual animal behavior as an earthquake precursor and of instances in which animals behaved normally prior to a moderate or large earthquake. We prepared briefing volumes describing the cultural significance and interpretation of seismicity for cultures other than our own with which we were likely to have contact. This information helped us assess the impact of cultural expectations on our data set. These briefing volumes are one of the work products of our project and are included in this final report.
Since our goal was to increase the ability to predict earthquakes, we avoided study of earthquakes with known foreshocks since in those cases the unusual animal behavior might have resulted simply from the foreshocks. Our data indicates that unusual animal behavior occurs a few hours to a few days before some, but not most, earthquakes that do not have known foreshocks.
Our studies of earthquake folklore support the same conclusion (pp 121-144 of this report). Even when unusual animal behavior is a precursor to a particular earthquake, most individual animals behave normally. This creates a signal to noise ratio that will reduce the potential for direct use of unusual -animal behavior in earthquake prediction, but the analysis of some animals reactions might help to identify physical precursors to at least some earthquakes.
Each phase of this research program has produced one or more completed work products. These products, which follow, compose our final report.

Wiley Hydroelectric Project is a proposal by the Idaho Power Company to develop hydroelectricity near Bliss, Idaho, by building a dam on the Snake River (fig. 1). The proposed dam would impound a narrow reservoir as deep as 85 feet in a free-flowing reach of the river that extends from the upper reach of water impounded by the Bliss Dam to the foot of the Lower Salmon Falls Dam, nearly 8 miles farther upstream. The proposed dam would be built in three sections: a spillway section and a powerhouse (intake) section to be constructed of concrete in the right-handed part, and an embankment section to be constructed as a zoned-fill of selected earth materials in the left-hand part. (Right and left are to be understood in the sense of looking downstream.) In August, 1979, the Idaho Power Company was granted a 3-year permit (Project No. 2845) by the Federal Energy Regulatory Commission (FERC) to make site investigations and environmental studies in the project area. A year later, on August 26, 1980, the company applied to FERC for a license to construct the project. On October 8, 1980, as explained in a letter by William W. Lindsay, Director of the Office of Electric Power Regulation, the company was given 90 days to correct certain deficiencies in the application. Because several of the deficiencies identified by Mr. Lindsay pertain to geologic aspects of the project, his letter is attached to this report as Appendix A. Hereafter in this report, the deficiencies listed by Mr. Lindsay are identified by the numerical entries in his letter. The Idaho Power Company is referred to as the applicant.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr81569","usgsCitation":"Malde, H.E., 1981, Geologic factors pertinent to the proposed A.

Measurements of base flow were made at 52 additional sites in the region. The report describes the hydrologic setting of this important coal region and summarizes the surface-water data collected at the monitoring sites from August 1978 through September 1979. Coal mining and lease activities in each of the monitored basins also are described.
Where possible, hydrologic impacts of coal mining are evaluated. Impacts include increases in streamflow and degradation of surface-water quality due to water discharged from underground mines. Other impacts include removal of water from ground-water storage, changes in the natural ground-water flow system, and possibly the diminution of spring flows.
Adequacy of the monitoring network to detect hydrologic changes due to mining is evaluated. In order to fully assess and quantify the impacts, comprehensive studies and monitoring of the ground-water system and water produced in mines are needed.

A comprehensive investigation of the area 's ground-water resources will be made as part of the U.S. Geological Survey 's Regional Aquifer-System Analysis (RASA) program. Basaltic and sedimentary rocks in the Snake River Plain yield large quantities of water that are vital to the area 's agricultural economy. Basaltic rocks predominate in the eastern Snake River Plain and have especially high water-yielding capabilities. Surface water, largely from the Snake River, is extensively used for irrigation and is a major source of recharge to the ground-water system. Springs issuing from basaltic rocks that form the Snake River Canyon wall near Twin Falls are the major points of ground-water discharge. Increased use of ground water for irrigation is causing concern as to the effect of large-scale withdrawals on spring flow. Ground-water flow models will be used to improve understanding of the hydrologic system, and, if feasible, to aid in evaluating management alternatives. Ground-water quality will be defined and geochemical techniques used to determine the effects of water-rock reactions on water quality. Several reports are planned on different phases of the project, concluding with a summary report.

The metasedimentary rocks are a former miogeosynclinal sequence of marl and limestone now metamorphosed to calc-silicate hornfels and marble. A pelecypod found in the calc-silicate hornfels has been tentatively identified as a Mesozoic bivalve, possibly Inoceramus pseudomytiloides of Early Jurassic age. These metasedimentary rocks are similar in lithology, structure, and gross age to the metasedimentary rocks of the Boyden Cave roof pendant and are assigned to the Lower Jurassic Kings sequence. The younger metaigneous rocks are metamorphosed shallow-in trusi ve rocks that range in composi tion from granodiorite to rhyolite. These rocks are similar in composition and age to the metavolcanic rocks of the surrounding Merced Peak quadrangle and nearby Ritter Range, and probably represent necks or dikes that were one source for the meta volcanic rocks. The roof pendant is intruded by several plutons, ranging in composition from dioritic to highly felsic, that constitute part of the granodiorite of Jackass Lakes, also M middle Cretaceous age. The contemporaneous suites of metaigneous, metavolcanic, and plutonic rocks in the region represent a middle Cretaceous period of calc-alkalic volcanism and plutonism in the central Sierra Nevada and are interpreted as part of an Andean-type volcanic-plutonic arc. \r\n\r\nThree deformations are documented in the roof pendant. The first deformation is reflected only in the metasedimentary rocks and consists of northeast-to east-west-trending folds. Similar structures occur in the Boyden Cave roof pendant and in the Calaveras Formation and represent a Middle Jurassic regional deformation. Evidence of the second deformation occurs in the metasedimentary and metaigneous rocks and consists of folds, faults, minor structures, and regional metamorphism along N. 25? W. trends. Crosscutting of these structures by the contemporaneous granodiorite of Jackass Lakes indicates that this deformation occurred simultaneously with volcanism and plutonism during the middle Cretaceous. The third deformation involved both the roof pendant and adjacent plutonic rocks and consists of folds, faults, schistosities, and regional metamorphism along N. 65? -900 W. trends. Crosscutting of similar structures in other middle Cretaceous plutonic rocks of the Merced Peak quadrangle by undeformed late Cretaceous plutonic rocks indicates a regional deformation of middle to late Cretaceous age. Structures of similar style, orientation, and age occur elsewhere in metavolcanic and plutonic rocks throughout the central Sierra Nevada.","language":"ENGLISH","doi":"10.3133/pp1154","usgsCitation":"Nokleberg, W., 1981, Stratigraphy and structure of the Strawberry Mine roof pendant, central Sierra Nevada, California: U.S. Geological Survey Professional Paper 1154, 18 p., https://doi.org/10.3133/pp1154.","productDescription":"18 p.","costCenters":[],"links":[{"id":104565,"rank":700,"type":{"id":15,"text":"Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_4742.htm","linkFileType":{"id":5,"text":"html"},"description":"4742"},{"id":125088,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1154/report-thumb.jpg"},{"id":65437,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1154/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":65438,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/pp/1154/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":65439,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1154/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1de4b07f02db6a9c50","contributors":{"authors":[{"text":"Nokleberg, W.

Q-mode factor analysis of 29 samples of this granite shows that five bulk compositions are required to explain the observed variances of 33 constituents in these samples. Models presented in this paper show that the origin of the granite can be accounted for by the mixing of a starting liquid with two ranges of solid compositions such that all five compositions are granitic. \r\n\r\nThere are several features of the granite of Lankin Dome that suggest derivation by partial melting and, because the proposed source region was inhomogeneous, that more than one of the five end members may have been a liquid. Data for the granite are compatible with derivation from rocks similar to those of the metamorphic complex that the granite intrudes. Evidence for crustal derivation by partial melting includes a strongly peraluminous nature, extremely high differentiation indices, high contents of incompatible elements, generally large negative Eu anomalies, and high initial lead and strontium isotopic ratios. If the granite of Lankin Dome originated by partial melting of a heterogeneous metamorphic complex, the initial magma could reasonably have been composed of a range of granitic liquids. \r\n\r\nFive variables were not well accounted for by a five-end-member model. Water, CO 2 , and U0 2 contents and the oxidation state of iron are all subject to variations caused by near-surface processes. The Q-mode factor analysis suggests that these four variables have a distribution determined by postmagmatic processes. The reason for failure of Cs0 2 to vary systematically with the other 33 variables is not known. Other granites that have lost large amounts of uranium possibly can be identified by Q-mode factor analysis.","language":"ENGLISH","doi":"10.3133/pp1225","usgsCitation":"Stuckless, J., and Miesch, A., 1981, Petrogenetic modeling of a potential uranium source rock, Granite Mountains, Wyoming: U.S. Geological Survey Professional Paper 1225, 34 p., https://doi.org/10.3133/pp1225.","productDescription":"34 p.","costCenters":[],"links":[{"id":170415,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1225/report-thumb.jpg"},{"id":65424,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1225/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a81e4b07f02db649ee2","contributors":{"authors":[{"text":"Stuckless, J.

Maximum measured flow of Otter Creek, an interrupted stream, was 1.2 cubic feet per second. The water chemistry was dominated by sodium, magnesium, and sulfate ions, with a maximum dissolved-solids concentration of 3,540 milligrams per liter. Chemistry of groundwater inflow is dominated by sodium, magnesium, and sulfate. A discharge of 156 cubic feet per second from the Tongue River Reservoir into the Tongue River complicated interpretation of groundwater discharge to the reach downstream from the reservoir. Many reaches of gain and loss were observed along the Tongue River; the flow near the mouth was 233 cubic feet per second. Minor changes in quality of the base flow indicate groundwater discharges dominated by sodium, sulfate, and bicarbonate plus carbonate. Dissolved-solids concentration increased from 506 milligrams per liter near the dam to 630 milligrams per liter near the mouth. Maximum measured flow of Rosebud Creek was 19.0 cubic feet per second. Water quality in the upper reaches was dominated by magnesium, calcium , and bicarbonate, with dissolved-solids concentrations ranging from 560 to 703 milligrams per liter.

The detailed study of these earthquakes provides a tool for gaining insight into the tectonic and physical processes responsible for the generation of damaging earthquakes. This catalog contains the fundamental parameters for earthquakes located within and adjacent to the seismograph network operated by the U.S. Geological Survey (USGS), during the third quarter of 1977.
The motivation for these detailed studies has been described by Pakiser and others (1969) and by Eaton and others (1970). Similar catalogs of earthquakes for the years 1969, 1970, and 1971 have been prepared by Lee and others (1972b, c and d). Catalogs for the first, second, third, and fourth quarters of 1972 and the first, second, third and fourth quarters of 1973 have been prepared by Wesson and others (1972a, b, 1973b, and 1974a and b), by Bufe and others (1975), and by Lester and others (1976a and b). Catalogs for the years 1974, 1975 and 1976 and the first quarter of 1977 have been prepared by Lester and Meagher (1978), by McHugh and Lester (1978 and 1979) and by Marks and Lester (1980a and 1980b). The basic data contained in these catalogs provide a foundation for further studies.
This catalog contains data on 855 earthquakes in central California. Arrival times at 205 seismograph stations were used to locate the earthquakes listed in this catalog. Of these 193 were telemetered stations operated by USGS. Readings from the remaining 12 stations were obtained through the courtesy of the Seismographic Stations, California Institute of Technology, Pasadena, University of California, Berkeley (UCB), and the California Department of Water Resources, Sacramento.
The Seismographic Station of the University of California, Berkeley, has for many years published a bulletin describing earthquakes in northern California and the surrounding area and listing readings at UCB stations from more distant events. The purpose of the present catalog is not to replace the UCB Bulletin, but rather to supplement it, by describing the seismicity of a portion of central California in much greater detail.
