Most U.S. Bureau of Mines reports on the geology and mineral resources of Alaska that were published or placed in open files through April 30, 1974, are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 2). References to reports that deal with...
Time-of-travel of solutes for New River near Geismar, Louisianna
Anthony J. Calandro
1974, Open-File Report 74-94
A water tracer (2.0 liters of Rhodamine WT, 20 percent) was injected into New River about 1 mile northwest of Geismar (river mile 26.1) at 0900 hours on April 3, 1974. Figure 1 is a location map showing the stream and sampling sites.As the water tracer moved downstream and dispersed,...
Sediment characteristics of five streams near Harrisburg, Pa., before highway construction
Lloyd A. Reed
1974, Open-File Report 74-140
Rainfall, streamfiow, sediment, and turbidity data are being collected as part of a study to evaluate the effects of highway construction on sediment discharge. The study is also designed to determine the effectiveness of different erosion-control measures in reducing sediment discharges. The study area, near Enola, Pa., consists of five...
Geological Survey open-file reports of Alaska indexed by quadrangle
Edward Huntington Cobb
1974, Open-File Report 74-7
The Geological Survey places in open files reports and maps that are preliminary or ephemeral in nature, are of interest to a small audience only, or consist of masses of essentially raw data. These reports and maps are available to the public and may be consulted at various Geological Survey...
A preliminary report on a zone containing thick lignite beds, Denver Basin, Colorado
Paul E. Soister
1974, Open-File Report 74-27
A zone of lignite beds of Paleocene age in the Denver Formation (Upper Cretaceous and Paleocene) lies about 800-1,500 feet above the well-known and extensively mined coal beds of the Laramie Formation (Upper Cretaceous). The zone is a few hundred to as much as 500 feet thick. Where lignite beds...

Edward Huntington Cobb
1974, Open-File Report 74-335
Geological Survey reports published as Professional Papers, Bulletins, Water Supply Papers, and Circulars are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 3). This index does not include reports that deal only with administrative matters or that were placed in open files...
Gravel resources, urbanization, and future land use, Front Range Urban Corridor, Colorado
James M. Soule, Harold R. Fitch
1974, Open-File Report 74-178
An assessment of gravel needs in Front Range Urban Corridor markets to 2000 A.D., based on forecast population increases and urbanization, indicates that adequate resources to meet anticipated needs are potentially available, if future land use does not preclude their extraction. Because of urban encroachment onto gravel-bearing lands, this basic...
Hydrology of the Dismal Swamp, Virginia-North Carolina
William Francis Lichtler, Patrick Neil Walker
1974, Open-File Report 74-39
The Dismal Swamp, on the border between eastern Virginia and North Carolina is one of the few remaining large (approximately 210,000 acres) areas of wet wilderness in the eastern United States. There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.Oaks and Coch...
Basic heat-flow data from the United States
J.H. Sass, Robert J. Munroe
1974, Open-File Report 74-9
It has been impossible to document fully in source papers, the large number of heat-flow results from the United States that have been published in recent years. The basic data of the major American research groups active in heat flow are tabulated in this report. Quantities tabulated include temperature, thermal...
