Runoff from rain and snow
A. M. Piper
1948, Eos, Transactions, American Geophysical Union (29) 511-524
The basic principles of the idealized hydrologic cycle are reviewed with emphasis on storage and movement of water in the soil. A distinction is made between ground‐water runoff and overland runoff in terms of storage and lag, expressed as accumulated deviations from uniform flow over a period of several years....
Trends in runoff in the Pacific Northwest
C. C. McDonald, W. B. Langbein
1948, Eos, Transactions, American Geophysical Union (29) 387-397
The diminution in runoff in the Pacific Northwest, particularly the Columbia River Basin, during the past 50 years, and its hydrologic significance are discussed in this paper. An analysis of the rainfall‐runoff relations for the Basin is made in order to explain the different influence of short‐ and long‐term precipitation...
Quality of water in the northwest
C. S. Howard
1948, Eos, Transactions, American Geophysical Union (29) 379-383
AbstractThe quality of natural waters, as judged by the dissolved mineral content, is quite varied throughout the Northwest. The concentrations of dissolved solids range from less than 50 ppm for many of the surface waters in Washington and Oregon, to several thousand ppm in...
Effect of water temperature on flow of a natural stream
William Stewart Eisenlohr Jr.
1948, Eos, Transactions, American Geophysical Union (29) 240-242
Approximately three per cent of the variation in streamflow of the Kootenai River near Copeland, Idaho, has been found to be associated with variation in water temperature. This has been determined by correlation analysis of residuals in streamflow that were not accounted for by either gage height or slope....
Notes on the Archaeology of the Utukok River, Northwestern Alaska
Raymond M. Thompson
1948, American Antiquity (14) 62-65
Early in May 1947, a United States Geological Survey field party of five was flown by ski plane to the headwaters of the Utukok River in northwestern Alaska, about 200 miles southwest of Barrow. Three 18–foot canvas boats of a special folding design were taken in along with enough equipment...
Heavy metals in altered rock over blind ore bodies, East Tintic District, Utah
Thomas Seward Lovering, V.P. Sokoloff, Hal T. Morris
1948, Economic Geology (43) 384-399
Standard chemical tests and spectroscopic analyses of altered Tertiary lavas that occur above blind ore bodies in the East Tintic district, Utah, have failed to show any evidence of the mineralization in the underlying dolomites. A new technique involving dithizone was used in the field to test ammonium acetate extracts...
Distribution of coastal black-sands in North Carolina, South Carolina, and Georgia, as mapped from an airplane
V.E. McKelvey, James R. Balsley
1948, Economic Geology (43) 518-524
Black-sand beach concentrates are more widely distributed along the beaches of North Carolina, South Carolina, and Georgia than has been recorded heretofore, as shown by a map prepared by airplane reconnaissance. The map shows also that the black sands diminish in abundance northward, that their distribution is in part related...
The bedding-replacement fluorspar deposits of Spar Valley, Eagle Mountains, Hudspeth County, Texas
Elliot Gillerman
1948, Economic Geology (43) 509-517
The Spar Valley fluorspar district in the Eagle Mountains, Hudspeth County, Texas, is one of the few in the western United States containing bedding-replacement fluorspar deposits. The deposits at Spar Valley resemble the bedding-replacement deposits of the Cave in Rock fluorspar district of southern Illinois. Two distinct deposits, the North...

A sensitive field test for heavy metals in water
Lyman C. Huff
1948, Economic Geology (43) 675-684
A semiquantitative colorimetric analytical method using dithizone to detect traces of heavy metals in natural water is described. Although reagents of exceptional purity are required, only simple equipment is needed and the test can be made in a few minutes in the field. A combined mixed color and mono color...
Geology and ground water of the Casablanca Basin, Chile
G. C. Taylor Jr.
1948, Economic Geology (73) 661-674
"In the uplands the Cretaceous granodiorite and granite contain water in the weathered zones, and in joints and fractures. These yield small supplies of good water to springs and to shallow domestic and stock wells. The alluvial fill of the lowlands contains a zone of saturation that is sustained by...

Ground water hydraulics as a geophysical aid
John G. Ferris
1948, Technical Report 1
The publication of the non-equilibrium formula in 1935 in a paper by Theis marked the opening of a new era in the analysis and understanding of the hydraulics of percolating ground waters. Through the past decade 9 an ever-increasing number of engineers and geologists have become familiar-with the application of...

Batholith and associated rocks of Corona, Elsinore, and San Luis Rey quadrangles southern California
Esper S. Larsen Jr.
1948, GSA Memoirs
The batholith of Southern and Lower California is exposed continuously from near Riverside, California, southward for a distance of about 350 miles. In central Lower California it is covered in part by younger rocks, but discontinuous bodies extend to the southern end of Lower California, and hence the batholith is...

Experimental drilling in Chattanooga shale
Andrew Brown
1948, Trace Elements Memorandum 63
Information on which specifications were originally drawn for drilling the Chattanooga shale was obtained largely from the TVA, whose geologists and driller laid great stress on the difficulties of maintaining circulation in their ho;es. The stated that the shale itself was not particularly difficult to core, the trouble being...
Monazite in concentrations from Idaho placer operations
1948, Trace Elements Memorandum 56
During the summer of 1947 the Atomic Energy Commission informally requested the Geological Survey collect sampled of concentrates from Idaho placer operations that might be useful for experimental study of monazite recovery. Some fourteen active gold-dredging operations were examined and sampled by Fred M. Chase during August and September 1947....

The Volcano Letter was an informal publication issued at irregular intervals by the Hawaiian Volcano Observatory (HVO) during the years 1925 to 1955. Individual issues contain information on volcanic activity, volcano research, and volcano monitoring in Hawaii. Information on volcanic activity at other locations is also occasionally included.The Volcano Letter...
