An evaluation of the use of drillers' logs in lithologic studies of the Ogallala Formation of the southern high plains of Texas, progress report, 1970-71
C.A. Wilson, Joe T. Smith, G.L. Thompson, W.M. Sandeen
1972, Open-File Report 72-451
Logs made by water-well drillers were analyzed in conjunction with test-hole drilling and geophysical logging to evaluate usefulness of the driller's log in delineating areas that would be suitable for artificial recharge of the Ogallala Formation. This preliminary study indicates that lack of detailed and accurate information in many drillers'...
Regional and other general factors bearing on evaluation of earthquake and other geologic hazards to coastal communities of southeastern Alaska
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-230
The great Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in seismically active regions. As a result, nine communities in southeastern Alaska were selected for reconnaissance investigations as an integral part of an overall program to evaluate earthquake and other geologic hazards...
Reconnaissance engineering geology of the Haines area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-229
The Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in urban areas. Study of the Haines area constitutes an integral part of an overall program to evaluate earthquake and other geologic hazards in most of the larger Alaska coastal communities. The evaluations...
Geological and geophysical investigations of an Apollo 9 photo anomaly near Point of Pines, Arizona
Calvin S. Bromfield, G. P. Eaton, D. L. Peterson, J.C. Ratte
1972, Open-File Report 72-51
An infrared photograph of southeastern Arizona, taken during the Apollo 9 multispectral terrain photography experiment in 1969, reveals a ringlike feature, some 3-4 miles (5-6 kin) in diameter, on the Natanes Plateau, 35 miles (56 kin) north of the town of Safford. Because the feature occurs in an area of...
The status of mineral resource information on the major land withdrawals of the Alaska Native Claims Settlement Act of 1971
Alaskan Geology Branch
1972, Open-File Report 72-394
This report is an analysis of the adequacy of the present level of geologic knowledge for making mineral resource potential evaluations of 126 federal land withdrawals made under the Alaska Native Claims Settlement Act. The withdrawals considered are Native village and regional deficiency areas (Sec. 11.A.3, ANCSA), classification and national...
Oil-shale assays on Grand Mesa, west-central Colorado
John R. Donnell
1972, Open-File Report 72-93
The attached diagram shows the Fischer assay histograms of oil shale from 4 core holes drilled on Grand Mesa. Core-hole locations are shown on-an insert map of Grand Mesa in the lower right corner of the diagram....
Evaluation of yields of wells in consolidated rocks, Virginia to Maine
Dagfin John Cederstrom
1972, Water Supply Paper 2021
In the North Atlantic region, Virginia to Maine, yields of industrial and municipal wells are the most reliable indicators of the water-yielding potential of consolidated rocks. Generally, such wells represent efforts to develop a maximum supply of water, they are 350 to 500 feet deep, and they utilize 60 to...
Floods of May 1968 in south Arkansas
R.C. Gilstrap
1972, Water Supply Paper 1970-A
The floods of May 1968 in south Arkansas produced the greatest peak discharges in the history of recorded streamflow at several gaging stations. Most notable of these floods was on Cossatot River near DeQueen, which has a continuous record since 1938. The peak discharge of 122,000 cubic feet per second...
Appraisal of shallow ground-water resources, Pueblo Army Depot, Colorado
Frank A. Welder, R. Theodore Hurr
1972, Open-File Report 72-447
The water supply for the Pueblo Army Depot, 15 miles wast of Pueblo, Colo., is obtained from wells that tap an aquifer in terrace alluvium. Withdrawals have resulted in a water-level decline of 27 feet, which adversely affects the discharge rate of individual wells. Furthermore, excessive pumpage has resulted in...
Definitions of selected ground-water terms, revisions and conceptual refinements
Stanley William Lohman
1972, Water Supply Paper 1988
For many years there has been a need for redefinition or more precise definition of certain ground-water terms used in publications by members of the U.S . Geological Survey. Another problem has been the expression of the coefficient of permeability (herein redefined as hydraulic conductivity) and the coefficient of transmissibility...
Appraisal of stream sedimentation in the Susquehanna River basin
Kenneth F. Williams, Lloyd A. Reed
1972, Water Supply Paper 1532-F
The Susquehanna River presently transports about 3.0 million tons of sediment annually (110 tons per square mile). Only about 1.8 million tons of sediment enters the head of Chesapeake Bay annually because some sediment is trapped behind the power dams on the lower Susquehanna. Measured annual sediment yields from subbasins...
