Geomorphology of the north flank of the Uinta Mountains
W. H. Bradley
1936, Professional Paper 185-I
The Uinta Mountains, whose northern margin is almost coincident with the southern boundary of Wyoming, extend from the Wasatch Range eastward across the northern part of Utah into northwestern Colorado. They were carved out of a large, simple anticlinal fold of sedimentary rocks arched up into essentially their present...
Flow‐duration characteristics of Illinois streams
J. H. Morgan
1936, Eos, Transactions, American Geophysical Union (17) 418-426
The paper entitled “An investigation of the flow‐duration characteristics of North Carolina streams,” by Thorndlke Saville and John Dargan Watson, which was published by the American Geophysical Union in its report of the Fourteenth Annual Meeting in 1933 (pp. 406–425), stimulated the writer, who is familiar with the streams discussed,...
Means of recognizing source beds
P.D. Trask, H.W. Patnode
1936, Conference Paper
Eight characteristics of sediments are considered as possible means of recognizing source beds: 1, quantity of organic matter in the sediments; 2, reducing power, which is a measure of ability of the sediments to reduce chromic acid; 3, color of sediments; 4, volatility of sediments; 5, degree of volatility, which...
The Battle Branch gold mine, Auraria, Georgia
Charles Frederick Park, R.A. Wilson
1936, Economic Geology (31) 73-92
The Battle Branch mine, in north-central Georgia, is well known locally for its pockets of exceptionally rich gold ore. During the period from May 24, 1934, to May 20, 1935, 781.97 ounces of bullion, of an average fineness of about 850, was shipped to the mint. The deposit is of...
Degree of reduction of sediments in the East Texas basin as an index of source beds
P.D. Trask, W.R. Keyte
1936, Conference Paper, Drilling and Production Practice
The research project on source beds, sponsored jointly by the U. S. Geological Survey and the American Petroleum Institute, for the past 18 months has undertaken a study of the degree of reduction as an index of source beds. As indicated in a previous paper on this same subject presented...
The channel‐storage method of determining effluent seepage
Oscar E. Meinzer, R.C. Cady, R.M. Leggette, V.C. Fishel
1936, Eos, Transactions, American Geophysical Union (17) 415-418
Some years ago the senior author, in collaboration with Norah Dowell Stearns, undertook to make a monthly inventory of the water‐supply of the Pomperaug River Basin, in Connecticut, from a study of data obtained by A. J. Ellis from 1913 to 1916. For this purpose approximate determinations or estimates were...
Several methods of studying fluctuations of ground‐water levels
Leland K. Wenzel
1936, Eos, Transactions, American Geophysical Union (17) 400-405
As a result of increased interest in ground‐water conditions in recent years, records of water‐levels in wells are now being collected in many places in the United States for the primary purpose of determining the relation of precipitation and other natural factors to fluctuations in water‐level. In the past, records...
Introduction: Some problems relating to fluctuations of ground‐water level
D. G. Thompson
1936, Eos, Transactions, American Geophysical Union (17) 337-341
When the program for the meeting of the Section of Hydrology a year ago was in preparation, it was suggested that a symposium be presented on the subject of the effects of the recent drought on ground‐water levels. The proposal was not carried out largely because at that time not...
Suspended matter in several small streams
Samuel K. Love
1936, Eos, Transactions, American Geophysical Union (17) 447-452
The measurement of the loads of suspended matter carried past 34 gaging‐stations located on streams in eight regional projects of the Soil Conservation Service has required greater precision in the measurement of discharge and a more intensive program for the collection of samples of suspended matter than has been found...
A source of heat‐energy in crystallization of granodiorite magma, and some related problems of volcanism
W. S. Burbank
1936, Eos, Transactions, American Geophysical Union (17) 236-255
Evidence obtained from thin sections, polished sections, and chemical analyses of granodiorite porphyries from the Ouray District of Colorado show that during crystallization of the granodiorite magma a number of shifts occurred in the equilibrium between the oxides of iron. These changes are reflected in processes of mineralization associated with...
Fluctuations of ground‐water levels in Utah
G.H. Taylor
1936, Eos, Transactions, American Geophysical Union (17) 378-382
Long‐time continuous records of the fluctuations of ground‐water levels have been obtained at relatively few locations in the United States. Among the few available records for Utah that extend continuously over a period of a year or more are those made in the Jordan River and Ogden valleys by the...
Movement of ground‐water
O. E. Meinzer
1936, Eos, Transactions, American Geophysical Union (17) 478-479
The movement of water through formations having capillary openings is generally laminar and obeys Darcy's law, at least down to very low gradients. About 1000 samples tested in the laboratory of the United States Geological Survey have coefficients of permeability ranging from 0.001 to 90,000, indicating probable velocities ranging from...
Review of the work of W. J. McGee on ground‐water levels
O. E. Meinzer
1936, Eos, Earth and Space Science News (17) 386-390
W J McGee was a scientist of broad‐interests, large vision, and unbounded enthusiasm for science and its application to human welfare. He was one of the earliest champions of the conservation of our natural resources. He rose from humble origin, by rigorous self‐discipline, to outstanding national leadership. He was absorbed...
Long‐time records of ground‐water levels on Long Island, New York
R.M. Leggette
1936, Eos, Transactions, American Geophysical Union (17) 341-344
As early at 1851 the need for information as to the position of the water‐table was recognized by workers on Long Island. In that year water‐level measurements were made in about 32 domestic wells in the southern part of Kings and Queens counties, New York (W. J. McAlpine, Report made...
