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....
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...
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'...
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....
