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...

Ground-water and drainage problems in the Whitney terrace area, Boise, Idaho
S. W. West
1955, Open-File Report 55-192
Ground-water levels in the Whitney terrace area, after many years of rise owing to downward percolation of water from irrigated land, became nearly stabilized by 1935.  Strong seasonal water-level fluctuations of 8 to 10 feet, however, are common in the Boise Valley.  In recent years, the Whitney terrace has been...
Geology of the northern Black Hills bentonite mining district

On the air-scattering of gamma rays from thick uranium sources
Arthur Y. Sakakura
1955, Trace Elements Investigations 595
Semiquantative interpretation of data from airborne radioactivity surveying requires detailed knowledge of air-scattered gamma-ray intensity at considerable air distances from natural, thick uranium sources. Based on the concept of an elementary source of infinite thickness rather than on the classical point source, semi-empirical expressions, are developed for measured gamma-radiation intensities from . the...
