Preliminary geologic map and structure sections of the Shaktolik River area, Alaska
William W. Patton Jr., Robert S. Bickel
1955, Open-File Report 55-134
The U.S. Geological Survey began stratigraphic and structural studies in the southern half of the Koyukuk Cretaceous basin in 1954. During June 1954, the Shaktolik River was traversed by boat from near the confluence of Brass Pan Creek to Norton Sound. All cutback exposures along the river were examined and,...
Water levels in observation wells in Santa Barbara County, California; in 1954
K. S. Muir
1955, Open-File Report 55-117
The investigation of the ground-water resources of Santa Barbara County was continued (luring 1954 in cooperation with the Santa Barbara County Wallet Agency. Monthly water-level measurements were made in 182 wells in 6 of which automatic water-level recorders were operated. Earlier measurements covering the period 1941 through 1952 have been...
Engineering geology as applied to highway construction
Leonard M. Gard Jr.
1955, Open-File Report 55-46
A geologic study of the site for a relocated segment of State Highway 93 northwest of Denver Colo., was made by by the Engineering Geology Branch of the U.S. Geological Survey as a demonstration of the applicability of geologic mapping to problems of highway construction. The relocated segment provides access...
Ground-water data collected in the Missouri River basin units in Kansas during 1954
B.J. Mason, Linda Loye
1955, Open-File Report 55-109
Ground-water studies in the Missouri River Basin were begun by the United States Geological Survey during the fall of 1945 as a part of the program for development of the resources of the basin by the U.S. Bureau of Reclamation and other Federal Agencies. The studies of the ground-water resources...
Water-resources program of the Geological Survey in the Midwestern States
C. G. Paulsen
1955, Open-File Report 55-137
The program of basic water-resources investigations by the U.S Geological Survey in the Midwestern states is a highly coordinated undertaking. It represents a partnership among Federal, State, and participial agencies that has developed during the past 60 years from the mutual desire to obtain and maintain optimum knowledge of out...
The relation between composition and swelling in clays
Margaret D. Foster
1955, Open-File Report 54-91
The phenomenon of swelling is associated with the hydration of clays; however, all clays do not swell when hydrated. those of the kaolin group, for example, exhibit little or no swelling on hydration. Sodiwm montmoillonite, on the other hand, characteristically swells in water to many times its dry volume. Calcium...
An electrical device for computing theoretical draw-downs of ground-water levels
Irwin Remson, M.H. Halstead
1955, Open-File Report 55-149
The construction, calibration and use of an electrical "slide rule" for computing theoretical drawdowns of ground-water levels are described. The instrument facilitates the computation of drawdowns under given conditions of discharge or recharge by means of the Theis nonequilibrium equation. It is simple to construct and use and can be...
