Surficial geology and geomorphology of Potter County, Pennsylvania
C. S. Denny
1956, Professional Paper 288
Potter County is located in the Appalachian Plateaus of north-central Pennsylvania and contains the headwaters of the Genesee River, the Allegheny River, and the Susquehanna River. Drift of Wisconsin age covers the northeastern part of the county. This study includes a detailed survev of the surficial deposits of the Genesee...
Geology and mineral resources of the Ivanpah quadrangle, California and Nevada
D. F. Hewett
1956, Professional Paper 275
The Ivanpah quadrangle covers about 3,900 square miles in the northeastern part of the Mojave Desert of southeastern California and southern Nevada. It includes many mountain ranges 6,000 to 7,000 feet in altitude, and a single peak, Potosi Mountain, attains 8,504 feet. The ranges are separated by broad alluvial filled...
Geology of Saipan, Mariana Islands; Part 1, General geology
Preston E. Cloud Jr., Robert George Schmidt, Harold W. Burke
1956, Professional Paper 280-A
Saipan, situated about 15° N. and 146° E., is one of the larger and more southerly of the Mariana Islands. The 15 small islands of this chain are strung along an eastwardly convex ridge for more than 400 miles north to south, midway between Honshu and New Guinea and about...
Ephemeral streams - Hydraulic factors and their relation to the drainage net
Luna Bergere Leopold, John P. Miller
1956, Professional Paper 282-A
The hydraulic factors of width, depth, velocity, and suspended sediment load of ephemeral streams near Santa Fe, N. Mex., were measured during flood flow. Later, channel slope was measured. These flood-flow data, in conjunction with an analysis of drainage-basin configuration by the methods proposed by Horton, are used to determine...
Comparison of the pebbles of the Shinarump and Moss Back members of the Chinle formation
Howard Franklin Albee
1956, Trace Elements Memorandum 832
Lithology, color, size, sphericity, and roundness of pebbles from the Shinarurnp and Moss Back members of the Chinle formation were analyzed and compared. The difference in the quartz:quartzite:chert ratios of the pebbles, the presence of limestone and siltstone pebbles, and to a lesser degree,the difference in color of pebbles serve...
Preliminary report on the geology of San Nicolas Island, California
J. G. Vedder, J.E. Schoelhamer, M.C. Israelsky
1956, Open-File Report 56-126
The U. S. Geological Survey, at the request of the Director of Naval Petroleum Reserves, undertook a geologic investigation of San Nicolas Island, Ventura County California, in the spring of 1955. This preliminary report summarizes present knowledge concerning the general stratigraphy and structure of the island. Additional surface and underwater...
Diatremes and craters attributed to natural explosions
Eugene Merle Shoemaker
1956, Trace Elements Memorandum 1090
Diatremes - volcanic pipes attributed to explosion - and craters have been studied to infer the ultimate causes and physical conditions attending natural explosive processes. Initial piercement of diatremes on the Navajo reservation, Arizona was probably along a fracture propagated by a high-pressure aqueous fluid. Gas rising at high velocity along...
