Cretaceous sedimentation and tectonism in the southeastern Kaiparowits region, Utah
Fred Peterson
1969, Open-File Report 69-202
Upper Cretaceous strata in the southeastern Kaiparowits region of south-central Utah consist of approximately 3,500 feet of interfingering sandstone, mudstone, shale, and coal in the Dakota Formation (oldest), Tropic Shale, Straight Cliffs Formation, and Wahweap Formation (youngest). The formations consist of several depositional facies that can be recognized by characteristic...
Pecos National Monument, New Mexico: Its geologic setting
Ross Byron Johnson
1969, Bulletin 1271-E
The ruins of the pueblos and missions of Pecos lie on the east bank of Glorieta Creek near its junction with the Pecos River at the south end of the Sangre de Cristo Mountains in north-central New Mexico. Here the Pecos River and Glorieta Creek have formed a broad rolling...
An analysis of gravity data in Area 12, Nevada Test Site
R. R. Wahl
1969, Open-File Report 69-309
The gravity data available from Healey and Miller (1963a) were augmented by new observations along three profiles through two new drill holes in Area 12; UEI2t #1 and UEI2p #1. The data were interpreted to allow evaluation of the geologic structure prior to the planning and excavation of two...
Ground water in the Ogallala formation in the southern high plains of Texas and New Mexico
J.G. Cronin
1969, Hydrologic Atlas 330
The Ogallala Formation of Tertiary (Pliocene) age is the principal aquifer in the Southern High Plains of western Texas and eastern New Mexico. This heavily pumped aquifer supplies practically all the water used for irrigation, municipal, industrial (except oil-field repressuring), and domestic purposes. Although the ground water in the Ogallala Formation...
Water resources of the Buffalo River Watershed, West-central Minnesota
Robert W. Maclay, L. E. Bidwell, Thomas C. Winter
1969, Hydrologic Atlas 307
The Buffalo River watershed includes two general physiographic areas – a glacial lake plain and an glacial moraine. The lake plain, which was formed by Glacial lake Agassiz more than 9,000 years ago, is extremely flat – sloping only a few feet per mile westward near the Red River of the...
The talc, soapstone, and asbestos deposits of Massachusetts
Newton Earl Chute
1969, Open-File Report 69-39
Several talc and soapstone deposits were worked in Massachusetts from about 1810 to 1922. Most of these deposits are in the Chester Amphibolite, or in serpentine lenses in or adjacent to the amphibolite along a belt that extends north-south across the State from Rowe to West Granville; it appears...
Recent surface movements in the Baldwin Hills, Los Angeles County, California
Robert O. Castle, R. F. Yerkes
1969, Open-File Report 69-36
The Baldwin Hills are located in the northwest part of the densely populated Los Angeles basin. They comprise one of several groups of isolated hills that extend along the northwest-trending Newport-Inglewood zone of folds and faults, a structural lineament identified with a series of very productive oil fields. In addition...
The Geologic Story of the Uinta Mountains
Wallace R. Hansen
1969, Bulletin 1291
The opening of the West after the Civil War greatly stimulated early geologic exploration west of the 100th Meridian. One of the areas first studied, the Uinta Mountains region, gained wide attention as a result of the explorations of three Territorial Surveys, one headed by John Wesley Powell, one by...
Geology, hydrology, and water quality in the Fresno area, California
Roland Westland Page, R.A. LeBlanc
1969, Open-File Report 69-328
The Fresno area comprises about 1.400 square miles lying west of the foothills of the Sierra Nevada and east of the trough of the San Joaquin Valley. The rainfall averages less than 10 inches per year causing agricultural development to depend mainly on surface-water deliveries and ground-water pumpage. Surface-water deliveries...
Hydrology of a part of the Big Sioux drainage basin, eastern South Dakota
Michael J. Ellis, Donald G. Adolphson, Robert E. West
1969, Hydrologic Atlas 311
In 1960 the U.S. Geological Survey, in cooperation with the South Dakota State Water Resources Commission and the South Dakota State Geological Survey, started a program for the hydrogeologic investigation of glacial drift in selected drainage basins in eastern South Dakota. This program was designed to delineate water-bearing deposits of...
Water resources of Wisconsin: Rock-Fox River basin
R. D. Cotter, R. D. Hutchinson, E.L. Skinner, D.A. Wentz
1969, Hydrologic Atlas 360
PURPOSE AND SCOPE The purpose of this report is to describe the physical environment, availability, distribution, characteristics, movement, quality, water problems, and use of water within the Rock-Fox River basin in order to aid in planning future water management within the basin. This report presents general information on the basin that was...
Regional hydrogeology of the Navajo and Hopi Indian Reservations, Arizona, New Mexico, and Utah, with a section on vegetation
M. E. Cooley, J. W. Harshbarger, J. P. Akers, W. F. Hardt, O.N. Hicks
1969, Professional Paper 521-A
The Navajo and Hopi Indian Reservations have an area of about 25,000 square miles and are in the south-central part of the Colorado Plateaus physiographic province. The reservations are underlain by sedimentary rocks that range in age from Cambrian to Tertiary, but Permian and younger rocks are exposed in about...
Kilauea Volcano: The 1967-68 summit eruption
Willie Tomoni Kinoshita, R. Y. Koyanagi, Thomas L. Wright, Richard S. Fiske
1969, Science (166) 459-468
On 5 November 1967 Kilauea volcano began erupting lava from vents on the floor of its summit pit crater. Halemaumau, 170 meters deep. This eruption ended nearly 2 years of the quiescence that followed a short lived eruption on the east  rift zone of Kilauea in December 1965 (1). The...
Mesozoic California and the underflow of Pacific mantle
Warren Hamilton
1969, Geological Society of America Bulletin (80) 2409-2429
The Mesozoic evolution of California is interpreted as dominated by the underflow of oceanic mantle beneath the continental margin. Underflow during part of Late Cretaceous time of more than 2000 km of the eastern Pacific plate seems required by the marine magnetic data. Correspondingly, varied oceanic environments—abyssal hill, island arc,...
Mean streamflow from discharge measurements
H. C. Riggs
1969, International Association of Scientific Hydrology - Bulletin (14) 95-110
Mean flow of a stream is usually computed from a continuous record of flow ai a gaging station. A less costly method consists of (1) estimating 12 individual monthly flows from one discharge measurement per month and a concurrent gaging station record on a nearby stream, using a...
Great Salt Lake, Utah: Chemical and physical variations of the brine, 1963-1966
D. C. Hahl, A.H. Handy
1969, Utah Geological and Mineralogical Survey Water-Resources Bulletin 12
Great Salt Lake is a shallow, closed-basin lake in northern Utah. Its surface area and concentration of dissolved solids vary in response to both annual and long-term climatic changes. The lake gains water mainly as streamflow from mountains to the east and loses water through evaporation. In 1965, at a...
Fission-track ages of accessory minerals from granitic rocks of the central Sierra Nevada batholith, California
C. W. Naeser, F. C. W. Dodge
1969, Geological Society of America Bulletin (80) 2201-2211
Ages of apatite, sphene, allanite, epidote, and garnet from plutonic rocks of the central Sierra Nevada and Inyo Mountains have been determined by the fission-track method.Ages of 44 specimens of apatite range from 54 to 128 m.y. Oldest apatites generally occur in rocks from the western portion of the batholith;...
The U.S. Geological Survey's gravity program in California
Howard W. Oliver
1969, Eos Science News (50) 543-545
Since the 1963 gravity symposium, the U.S. Geological Survey has entered into a cooperative program with the California Division of Mines and Geology, the Army Map Service, and several universities for the purpose of completing a 5-mgal Bouguer gravity map of the entire State of California at a scale of...
The structure and tectonic history of the eastern Aleutian Trench
Roland E. von Huene, George G. Shor Jr.
1969, Geological Society of America Bulletin (80) 1889-1902
The tectonic character of the eastern Aleutian Trench and some major events in its geologic history can be estimated from nine continuous seismic reflection records. A section of pre-trench, deep oceanic sediments rests on the down-warped crust that forms the trench. Nearly horizontal undeformed strata that unconformably overlie this deep...
