Annual peak discharges from small drainage areas in Montana through September 1979
R. J. Omang, C. Parrett, J. A. Hull
1955, Open-File Report 80-340
Annual peak stage and discharge data have been collected and tabulated for crest-stage gaging sites in Montana. The crest-stage program was begun in July 1955 to investigate the magnitude and frequency of floods from small drainage areas. The program has expanded from 45 crest-stage gaging stations initially to 173 stations...
Annual peak discharges from small drainage areas in Montana through September 1980

Geology of the Red House Cliffs area, San Juan County, Utah
Thomas E. Mullens
1955, Trace Elements Investigations 445
The Red Cliffs area comprises 296 square miles of canyon and plateau country in southwestern San Juan County, Utah.  The rocks that crop out in the area are mostly deposits of terrestrial environment and are of Permian, Triassic, Jurassic, and Quaternary ages.  The aggregate thickness of these rock is about...
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...
Relationship of uranium and other trace elements to post-Cretaceous vulcanism
Robert R. Coats
1955, Trace Elements Investigations 159
A regional study of the distribution of uranium, boron, tin, beryllium, niobium, lanthanum, lead, zirconium, lithium, and fluorine in 112 samples of Cenozoic volcanic rocks of predominately rhyolitic and dacitic composition has shown that the content of uranium has a significantly high positive correlation with that of niobium, beryllium, and...
Provenience of pyroclastic materials
C. S. Ross
1955, Geological Society of America Bulletin (66) 427-434
Recent studies of rhyolitic and pyroclastic materials, and in particular of welded tuffs and bentonites, show that they occur over wide areas and in volumes which greatly exceed earlier evaluations. Volcanic ash and bentonite occur in the eastern United States where such materials were long unrecognized. In most of the...
Sub-chattanooga residuum in Tennessee and Kentucky
C. Milton, L. C. Conant, V.E. Swanson
1955, Geological Society of America Bulletin (66) 805-810
Between the Chattanooga shale and the underlying limestone in parts of Tennessee and Kentucky is a clayey gray to brown zone as much as several feet thick. This represents an interval of limestone that has been leached by sulfuric acid formed by oxidation of the abundant pyrite in the black...
