Magnitude and frequency of summer floods in western New Mexico and eastern Arizona
F.W. Kennon
1955, Open-File Report 55-82
Numerous small reservoirs and occasional water-spreading structures are being built on the ephemeral streams draining the public and Indian lands of the Southwest as part of the Soil and Moisture Conservation Program of the Bureau of Land Management and Bureau of Indian Affairs.  Economic design of these structures requires some...
Geologic map of the Triangle A pegmatite, Custer County, South Dakota
A.J. Lang Jr.
1955, Miscellaneous Field Studies Map 44
The Triangle A pegmatite is 4 miles southeast of Custer in the SW 1/4, sec. 34, T. 3 S., R. 5 E., Custer County, S. Dak.  It may be reached from Custer by a gravel road 2.4 miles long that leaves U.S. Highway 16A at a point 3.2 miles east...
Radioactivity and uranium content of the Sharon Springs member of the Pierre shale and associated rocks in western Kansas and eastern Colorado
Edwin R. Landis
1955, Trace Elements Investigations 573
As a part of the Geological Survey's program of investigating uranium-bearing carbonaceous rocks on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission, a reconnaissance of the Sharon Springs member of the Pierre shale in western Kansas and eastern Colorado was conducted during 1954. The Sharon Springs...
Water requirements of the pulp and paper industry
Orville D. Mussey
1955, Water Supply Paper 1330-A
Water, of varied qualities, is used for several purposes in the manufacture of pulp and paper, as a vehicle for transporting the constituents of paper in the paper machines; as process water for cooking wood chips to make pulp; as a medium for heat transfer; and for washing the pulpwood,...
Conglomeratic sandstone strata at the base of the Brushy Basin member of the Morrison formation as related to uranium-vanadium deposits, southwestern Colorado and southeastern Utah
David A. Phoenix
1955, Trace Elements Investigations 565
In southwestern Colorado and southeastern Utah strata of conglomeratic sandstone are localized at the base of the Brush Basin shale member of the Morrison formation of Jurassic age. These strata are discrete lithologic units that contain sedimentary structures oriented in a prevailing easterly direction, they locally rest upon sandstone in...
Water-power resources in upper Carson River basin, California - Nevada
Harold L. Pumphrey
1955, Water Supply Paper 1329-A
West Fork Carson River offers the best opportunity for power development in the Carson River basin. The Hope Valley reservoir site could be developed to provide adequate storage regulation and concentration of fall would permit utilization of 1,400 feet of head in 51h miles below the clam site, or 1,900...
Ground-water conditions between Oracle and Oracle Junction, Pinal County, Arizona
L.A. Heindl
1955, Open-File Report 55-63
The development of the San Manuel copper prospect has greatly increased traffic along State Highway 77. Considerable interest in commercial possibilities along that road has resulted in a request by the Arizona State Land Department for information about the ground-water conditions between Oracle and Oracle Junction. This request came too...
Preliminary geologic evaluation of the Chena area, Alaska
John R. Williams
1955, Open-File Report 55-198
It seems fitting at this session of the Alaska Science Conference, the first to be held in the Fairbanks area, to give a preliminary summary of the practical results of a geologic investigation of the Chena area east of Fairbanks. The work was done by the Geological Survey in 1950....
Fossils from bore holes on the Eastern Shore Peninsula, Virginia
Ruth Todd, Julia A. Gardner, I. G. Sohn
1955, Open-File Report 55-181
This report lists Foraminifera, Mollusca, and Ostracoda in five bore holes that penetrated a maximum of 445 feet of section in sediments of Pleistocene and Miocene age, and discusses the paleoecologic and stratigraphic significance of the fossils. It includes the contents of references 6, 16, and 18 of Virginia Division...
Geology of two areas of pegmatite deposits in southeastern Alaska
C.L. Sainsbury
1955, Open-File Report 55-159
A pegmatite deposit about 600 feet in diameter crops on a high bluff less than one-half mile east of a small unnamed cove between Redfish and Byron Bays, on the west coast of Baranof Island, southeastern Alaska.The deposit which comprises several pegmatite bodies consists of quartz, albite-oligoclase, microcline and mica,...
Geology of the Copper King uranium mine, Larimer County, Colorado
Paul Kibler Sims, George Phair, Robert Hadley Moench
1955, Trace Elements Investigations 424
The Copper King mine in Larimer County, Colo., in the northern part of the Front Range of Colorado, was opened in World War I in an unsuccessful attempt to mine copper and zinc ore. In 1949, following the discovery of pitchblende on the dump, the mine was reopened, and it...
Provenience of pyroclastic materials
C. S. Ross
1955, Geological Society of America Bulletin (66) 427-434
Recent studies of rhyolitic and pyroclastic materials, and in particular of welded tuffs and bentonites, show that they occur over wide areas and in volumes which greatly exceed earlier evaluations. Volcanic ash and bentonite occur in the eastern United States where such materials were long unrecognized. In most of the...
Pleistocene geology of the southwestern Wind River Mountains, Wyoming
G.W. Holmes, J.H. Moss
1955, GSA Bulletin (66) 629-654
Patches of Buffalo till record the earliest glaciation in the southwestern Wind River Mountains. In places, these rest in youthful valleys cut in high gravel terrace. Two other younger and lower terraces are both topographically and stratigraphically associated with Buffalo till, which may indicate that the Buffalo advance was compound....
Zones of regional metamorphism in the Precambrian of northern Michigan
Harold L. James
1955, GSA Bulletin (66) 1455-1488
Precambrian rocks are exposed throughout an area of about 7500 square miles in northern Michigan. Of this area, approximately 3300 square miles is underlain by relatively unmetamorphosed Upper Precambrian (Keweenawan), about 2700 square miles by metamorphosed Middle Precambrian (Huronian), and about 1500 square miles by metamorphosed Lower Precambrian (“Archean”). Flat-lying...
Geology of the Huron River pitchblende occurrence, Baraga County, Michigan
R.C. Vickers
1955, Trace Elements Investigations 303
Small quantities of uranium-bearing minerals were discovered by a geologist of the Jones and Laughlin Ore Company during the summer of 1949 along the East Branch of the Huron River, sec. 1, T. 51 N., R. 30 W., Baraga County, Mich. Subsequent diamond drilling of the prospect by the Jones...
Radioactivity and uranium content of some Cretaceous shales, central Great Plains
Harry A. Tourtelot
1955, Trace Elements Investigations 298
The Sharon Springs member of the Pierre shale of Cretaceous age, a hard black organic-rich shale similar to the Chattanooga shale, is radioactive throughout central and western South Dakota, most of Nebraska, northern Kansas, and northeastern Colorado. In the Missouri River valley, thin beds of the shale contain as much...
