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'...
Geologic map of the Taruntius Quadrangle of the Moon
D.E. Wilhelms
1972, IMAP 722
The distribution of major physiographic provinces and geologic units of the Tarantius quadrangle is determined by the five intersecting circular multi-ringed mare basins. Three basins, i<span...
Map showing relative ease of excavation in the Salina quadrangle, Utah
Paul L. Williams
1972, IMAP 591-J
This map shows the relative ease (or difficulty) with which rocks and surficial deposits can be excavated. Because of rapidly changing technology of excavation and considerable local variability of many rock units, it is not practical to specifically categorize rock units according to type of equipment needed for their excavations....
Some effects of a heated pipeline on ground-water flow in Alaska
Charles E. Sloan, John D. Bredehoeft
1972, Open-File Report 72-349
The thaw bulb produced by a heated pipeline buried in a stream channel may intercept water confined in shallow unfrozen zones beneath a seasonally frozen layer. Resulting movement of ground water through the thaw bulb might produce quick conditions in the pipeline foundation materials. A digital model showed that such...
Limnological studies of Big Bear Lake, California
Elmer G. Pearson, George A. Irwin
1972, Open-File Report 72-295
Big Bear Lake exhibited seasonal changes in physical, chemical, and biological variables from June 1968 to June 1969.Dissolved-oxygen concentrations were depressed during the summer resulting in anaerobic conditions near the bottom of the lake. Water temperature decreased with depth in spring and summer, although classical thermal stratification was not observed....
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...
Placer deposits of Alaska
Edward Huntington Cobb
1972, Open-File Report 72-71
Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their...
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...
