A study of flow in alluvial channels: the effect of large concentrations of fine sediment on the mechanics of flow in a small flume
William Leland Haushild, Daryl Baldwin Simons, Everett V. Richadrson
1961, Report
A flume study was made using a natural river sand as the bed material, median diameter = 0. 54 millimeters. Clear-water flow was compared with flow containing from 6 1 000 to 65,000 parts per million of fine sediment (bentonite). The study shows that the form of bed roughness could...
Surface water records of Indiana, 1961
Water Resources Division, U.S. Geological Survey
1961, Report
The surface-water records for the 1961 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the...
Origin of Pennsylvanian underclay and related seat rocks
J. W. Huddle, S. H. Patterson
1961, Geological Society of America Bulletin (72) 1643-1660
Seat rocks, including underclay, underlie coal beds and show features such as roots, profiles similar to water-logged soils, lack of bedding, soil-like fracture, and gradation into normally bedded sedimentary rocks indicating that they were once soils. Coarse-grained seat rocks range from argillaceous to nearly pure quartz sandstone (ganister). Seat rocks...
Geophysical study of subsurface structure in southern Owens Valley, California
M. F. Kane, L.C. Pakisek
1961, Geophysics (26) 12-26
Gravity and seismic measurements in southern Owens Valley, California, have outlined a deep subsurface trough, bounded throughout the greater part of its length by steep faults. Depths to the bedrock floor along the central part of the valley range from 3,000 to 9,000 ft below the surface. The subsurface trough is divided into...
Reconnaissance study of quaternary faults in and south of Yellowstone National Park, Wyoming
D. Love
1961, Geological Society of America Bulletin (72) 1749-1764
Normal faults offset a bedrock surface scoured by Pleistocene ice in several areas within and south of Yellowstone National Park. Recurrent earthquake shocks and fresh appearance of some scarps suggest that movement is continuing along some faults. Four systems of faults are described. Quaternary movement occurred along more than 60 faults on the Mirror Plateau, 15...
Paleoecology of an early oligocene biota from Douglass Creek Basin, Montana
Richard L. Konizeski
1961, Geological Society of America Bulletin (72) 1633-1642
Douglass Creek basin lies west of the Continental Divide in the northern part of the Rocky Mountain physiographic province. Numerous minor environmental differences exist between the Douglass Creek area and the Pipestone Springs and Canyon Ferry areas east of the Divide. In the 19th century, however, the three areas had identical...
Tektite from Martha's Vineyard, Massachusetts
C. A. Kaye, C.C. Schnetzler, J.N. Chase
1961, Geological Society of America Bulletin (72) 339-340
A fragment of an oddly sculptured glass disc found on the cliff of Gay Head, on Martha's Vineyard, Massachusetts, is thought to be a tektite. Unless carried to Gay Head by man from one of the known tektite fields, it raises to three the number of tektite localities in the...
Geological significance of lead-alpha and isotopic age determinations of "alkalic" rocks of New England
Priestley Toulmin III
1961, Geological Society of America Bulletin (72) 775-779
Recent age determinations indicate that at least two groups of "alkalic" igneous rocks exist in New England, with ages of about 185 and 270 million years. Because of their lithologic and geologic similarities, all these rocks had previously been grouped with the White Mountains plutonic-volcanic series of New Hampshire. Until reliable petrographic or...
An aeromagnetic profile from anchorage to Nome, Alaska
E. R. King
1961, Geophysics (26) 716-726
A total-intensity profile was obtained on a 500-mile flight by a U. S. Geological Survey airplane from Anchorage to Nome, Alaska, on May 4, 1954. The average flight altitude was 6,000 ft above sea level except over the Alaska Range where the flight altitude was 9,000 ft. This profile crossed eight of the major...
Origin and development of the Three Forks Basin, Montana
G. D. Robinson
1961, Bulletin of the Geological Society of America (72) 1303-1313
The Three Forks Basin sprawls where the intricately deformed sedimentary and volcanic rocks of the Disturbed Belt along the Rocky Mountain front are faulted against the Precambrian metamorphic rocks that make the core of the Tobacco Root, Madison, Gallatin, and Beartooth ranges. Its eastern edge is linear, controlled by steep faults...
