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...
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...
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...
Annotated list of plants of Arctic Slope of Alaska
Lloyd Anthony Spetzman
1956, Open-File Report 56-110
The accompanying 5-page list of 439 higher plants was compiled as part of a manuscript to be included in a series of professional papers on Naval Petroleum Reserve No. 4 and adjoining areas.This check list describing the distribution, abundance, flowering period, plant growth on various rook types, and other habitat...
Relationships of calcium carbonate to lithology and vanadium-uranium deposits in Salt Wash sandstone of southwestern Colorado
Norbert Lee Archbold
1956, Open-File Report 56-2
This study was made to determine whether any relationship exists between lithology or vanadium-uranium deposits and calcium carbonate content in the Salt Wash member of the Morrison formation of Jurassic age. Results indicate that altered gray-green mudstone contains less carbonate than does unaltered red-brown mudstone. No significant difference exists between...
Preliminary report on waterpower resources of Cascade Creek, Scenery Creek, and Delta Creek near Petersburg, Alaska
Jesse Lane Colbert
1956, Open-File Report 56-26
The heavy precipitation and runoff, suitable storage sites near tidewater, and steep stream gradients are favorable to the development of hydroelectric power on the streams considered in this report. A geologic examination of the sites indicates that their development would not be hindered by any unusual geologic conditions.On the basis...
Drilling data in the Montfort, Rewey, Mifflin, Belmont, and Calamine quadrangles, Wisconsin
John Edward Carlson
1956, Open-File Report 56-23
Sixty-six churn drill holes aggregating 10,351 feet were drilled in the fall of 1955 in the zinc-lead district of southwestern Wisconsin (fig. 1). This drilling was part of a cooperative program of geologic mapping by the U. S. Geological Survey and the Wisconsin Geologic and Natural History Survey.The holes penetrate...
Ground water in the North Side Pumping Division, Minidoka Project, Minidoka County, Idaho
Emerson G. Crosthwaite, R. C. Scott
1956, Circular 371
The U. S. Bureau of Reclamation proposes to irrigate about 64, 000 acres, largely in southern Minidoka County north and west of the Snake River, with ground water from 175 wells; 13, 650 additional acres would receive surface water pumped to a high-line canal from Lake Milner. More than 20,000 additional...
