Ephemeral streams - Hydraulic factors and their relation to the drainage net
Luna Bergere Leopold, John P. Miller
1956, Professional Paper 282-A
The hydraulic factors of width, depth, velocity, and suspended sediment load of ephemeral streams near Santa Fe, N. Mex., were measured during flood flow. Later, channel slope was measured. These flood-flow data, in conjunction with an analysis of drainage-basin configuration by the methods proposed by Horton, are used to determine...
Geology and mineral resources of the Ivanpah quadrangle, California and Nevada
D. F. Hewett
1956, Professional Paper 275
The Ivanpah quadrangle covers about 3,900 square miles in the northeastern part of the Mojave Desert of southeastern California and southern Nevada. It includes many mountain ranges 6,000 to 7,000 feet in altitude, and a single peak, Potosi Mountain, attains 8,504 feet. The ranges are separated by broad alluvial filled...
Surficial geology and geomorphology of Potter County, Pennsylvania
C. S. Denny
1956, Professional Paper 288
Potter County is located in the Appalachian Plateaus of north-central Pennsylvania and contains the headwaters of the Genesee River, the Allegheny River, and the Susquehanna River. Drift of Wisconsin age covers the northeastern part of the county. This study includes a detailed survev of the surficial deposits of the Genesee...
Contributions to the geology of uranium and thorium by the United States Geological Survey and Atomic Energy Commission for the United Nations International Conference on Peaceful Uses of Atomic Energy, Geneva, Switzerland, 1955
Lincoln R. Page, Hobart E. Stocking, Harriet B. Smith
1956, Professional Paper 300
Within the boundaries of the United States abnormal amounts of uranium have been found in rocks of nearly all geologic ages and lithologic types. Distribution of ore is more restricted. On the Colorado Plateau, the Morrison formation of Jurassic age yields 61.4 percent of the ore produced in the United...
Permafrost and ground-water conditions in the Glennallen area, Alaska
Donald R. Nichols
1956, Open-File Report 56-91
This report is an outgrowth of permafrost and geologic field studies now in progress in the southeastern Copper River basin, Alaska and is in response to inquiries for information on permafrost and ground-water conditions. Various private and governmental groups have encountered severe differential settlement of building foundations on permafrost, and...
Geology of southeastern Ventura Basin, Los Angeles County, California
Edward L. Winterer
1956, Open-File Report 56-134
The Ventura Basin (see index map, fig. 1) has long been one of the important oil-producing districts of California. The eastern part of the Basin includes some of the oldest oil fields in the state and also several of those most recently discovered. Since 1937 several new fields have been...
Gravity survey of Ogden Valley, Weber County, Utah
Samuel Woods Stewart
1956, Open-File Report 56-112
Ogden Valley is a northwest trending valley within the Wasatch Mountains of north-central Utah. On the basis of geological evidence Ogden Valley is believed to be structurally controlled by normal faults along both the east and west margins. Gravity measurements in the valley definitely indicate a fault with at least...
Geology and petrology of the Lava Mountains, San Bernardino County, California
George I. Smith
1956, Open-File Report 56-109
The Lava Mountains are a range of low mountains along the northern edge of the Mojave Desert, California. The pre-Tertiary rocks consist of a few swell pendants of metamorphic rocks in Atolia quartz monzonite. Overlying these are small patches of volcanic and sedimentary rocks, probably Tertiary, which project into the...
Geology and ore deposits of the Monument Valley area, Apache and Navajo Counties, Arizona
Irving Jerome Witkind
1956, Open-File Report 57-124
In 1951 the U.S. Geological Survey undertook a program of uranium investigations in Apache and Navajo Counties, northeastern Arizona. The work had three major objectives. The first was to accumulate data basic to an understanding of the regional geology. The second was to appraise the Triassic strata as host rocks...
