Preliminary geologic report of Sadlerochit River area, 1948
Charles L. Whittington, Edward G. Sable
1948, Open-File Report 54-333
"The Sadlerochit River area" is the name that has been applied for purposes of convenience to that portion of the eastern part of the northern Alaska shown in Figure 1. The map covers an area of about 1400 square miles. The center of this map is a point approximately 55...
Application of Brianchon's theorem to construction of geologic profiles
J.B. Mertie Jr.
1948, Geological Society of America Bulletin (59) 767-786
Brianchon's theorem states that the three diagonals joining opposite vertices of a hexagon circumscribed about a conic are concurrent. A corollary of this theorem applies to a pentagon so that the points of tangency of an inscribed conic may be located. Any five non-concurrent straight lines in a plane, no...
Preliminary report on the stratigraphy and structure of the area of the Ipnavik River, Alaska
Karl Stefansson
1948, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 16
Geological Survey Party 1 returned to Umiat from Wolf Creek on August 5. Plans for the field season of 1947 called for geologic reconnaissance along part of the Ipnavik River and along the Colville River between the Ipnavik and Kurupa Rivers, to be completed before the end of the season....
Some solutional features of the limestone near Lexington, Kentucky
D.K. Hamilton
1948, Economic Geology (43) 39-52
Field work on the Ordovician limestones and shales of the Lexington area, Kentucky, has shown that no appreciable quantity of ground water is transmitted through interstitial openings in these rocks. Ground-water movement is restricted to joint planes and, to a lesser extent, bedding planes that have been enlarged by solution....
Annual rainfall and runoff in New England 
J.J. McAleer, C. E. Knox
1948, Eos, Transactions, American Geophysical Union (29) 903-908
This paper presents the results of studies of average rainfall and runoff, developed in the Office of the Division Engineer, New England Division, United States Corps of Engineers, in cooperation with the District Engineer, United States Geological Survey, and prepared in connection with flood‐control studies of the Connecticut and Merrimack...
Age of the Kingsbury conglomerate is Eocene 
Roland W. Brown
1948, GSA Bulletin (59) 1165-1172
The Kingsbury conglomerate and immediately overlying gravels on the east side of the Bighorn Mountains in Wyoming interfinger eastward with “Wasatch” strata. The latter contain Eocene vertebrates, species of which have been found in the Kingsbury conglomerate. In addition, the “Wasatch” strata contain an Eocene...
Quality of water in the upper Colorado River basin
C. S. Howard
1948, Eos, Transactions, American Geophysical Union (29) 375-378
In a drainage area as large as the Colorado River Basin there are naturally large differences in the quality of the surface waters. The chemical character of the water at six gaging stations on the Colorado River from near the headwaters to near the mouth is shown by the analyses...
Fluctuations in concentration of dissolved solids of some southwestern streams
J.D. Hem
1948, Eos, Transactions, American Geophysical Union (29) 80-84
The concentration of dissolved solids in waters of streams of the Southwestern United Stated fluctuates widely as the stream discharge changes. These fluctuations may be extensive in a period of a few days or even a few hours. Data in this paper show the extent of the day‐to‐day changes in...
