A system of regional agricultural land use mapping tested against small scale Apollo 9 color infrared photography of the Imperial Valley (California)
Claude W. Johnson, Leonard W. Browden, Robert W. Pease
1969, Open-File Report 71-158
Interpretation results of the small scale ClR photography of the Imperial Valley (California) taken on March 12, 1969 by the Apollo 9 earth orbiting satellite have shown that world wide agricultural land use mapping can be accomplished from satellite ClR imagery if sufficient a priori information is available for the...
Hydrology of a part of the Big Sioux drainage basin, eastern South Dakota
Michael J. Ellis, Donald G. Adolphson, Robert E. West
1969, Hydrologic Atlas 311
In 1960 the U.S. Geological Survey, in cooperation with the South Dakota State Water Resources Commission and the South Dakota State Geological Survey, started a program for the hydrogeologic investigation of glacial drift in selected drainage basins in eastern South Dakota. This program was designed to delineate water-bearing deposits of...
Availability of ground water for large-scale use in the Malad Valley-Bear River areas of southeastern Idaho: an initial assessment
W.L. Burnham, A.H. Harder, N. P. Dion
1969, Open-File Report 69-28
Five areas within the Bear River drainage of southeastern Idaho offer potential for further development of ground water--the valley north of Bear Lake, north of Soda Springs, Gem Valley, Cache Valley in Idaho, and Malad Valley in Idaho. Saturated deposits north of Bear Lake are too fine-textured to yield large...
Geologic effects of the Greeley event, Nevada Test site
Dayton Delbert Dickey, E.C. Jenkins, F. A. McKeown, W.H. Lee
1969, Open-File Report 69-73
The intermediate yield Greeley event, in which a nuclear device was detonated at a depth of 3,990 feet in Pahute Mesa at the Nevada Test Site, caused fracturing in rocks and spalling of rock from cliffs as far as 3 and 8 miles, respectively, from the detonation point....
Ground water in the Ogallala formation in the southern high plains of Texas and New Mexico
J.G. Cronin
1969, Hydrologic Atlas 330
The Ogallala Formation of Tertiary (Pliocene) age is the principal aquifer in the Southern High Plains of western Texas and eastern New Mexico. This heavily pumped aquifer supplies practically all the water used for irrigation, municipal, industrial (except oil-field repressuring), and domestic purposes. Although the ground water in the Ogallala Formation...
