Ground-water levels in observation wells in Oklahoma, 1965-66
D.L. Hart Jr.
1967, Open-File Report 67-285
The investigation of the ground-water resources of Oklahoma by the U.S. Geological Survey in cooperation with the Oklahoma Water Resources Board includes a continuing program to collect records of water levels in selected observation wells on a systematic basis. These water-level records: (1) provide an index to available ground-water supplies;...
Map of southeastern Maine showing heavy metals in stream sediments
Edwin V. Post, William L. Lehmbeck, William H. Dennen, Gary A. Nowlan
1967, Miscellaneous Field Studies Map 301
This map presents the initial results of a geochemical reconnaissance of stream sediment in southeastern Maine. Its purpose is to identify metal-rich areas that might be favorable for further detailed exploration. ...
Effects of the Truckee, California, earthquake of September 12, 1966
Reuben Kachadoorian, R. F. Yerkes, Arvi O. Waananen
1967, Circular 537
The Truckee, Calif., earthquake of September 12, 1966, had a magnitude of 5.4 on the Richter scale, as reported by the U.S. Coast and Geodetic Survey. It was felt over an area extending from San Francisco eastward to Salt Lake City and from Bakersfield northward beyond Chico, Calif. Ground breakage...
National Atlas, Indian tribes, cultures & languages
William C. Sturtevant
1967, Report
Tribal distributions depicted on these maps (and on all other tribal maps covering a comparable area) are arbitrary at many points. Detailed knowledge of tribal areas was acquired at different times in different regions. For example, by the time knowledge was gained of the areas occupied by Plains tribes, many...
Surveying the earth's resources from space
William T. Pecora
1967, Surveying and Mapping (27) 639-643
Two developments, aerial photography and airborne geophysical surveying techniques, have already increased the rate at which new knowledge of the world's resources can be acquired. But even with far wider use of the tools and techniques already available, the problems that face us are greater than our current ability to...
Radar remote sensing in biology
Richard K. Moore, David S. Simonett
1967, BioScience (17) 384-390
The present status of research on discrimination of natural and cultivated vegetation using radar imaging systems is sketched. The value of multiple polarization radar in improved discrimination of vegetation types over monoscopic radars is also documented. Possible future use of multi-frequency, multi-polarization radar systems for all weather agricultural survey is...
Explorers from space
Raymond W. Fary Jr.
1967, Journal of Geological Education (15) 99-104
The statement that a new era in exploration is opening will almost surely bring to mind the venturing of man into space and the ever more imminent exploration of the moon. The reference here, however, is to exploration of earth itself and to the unique capabilities for study of the...
The Alaska earthquake, March 27, 1964: effects on transportation, communications, and utilities
Malcolm H. Logan, Lynn R. Burton, Edwin B. Eckel, Reuben Kachadoorian, David S. McCulloch, Manuel G. Bonilla
1967, Professional Paper 545
This is the forth in a series of six reports that the U.S. Geological Survey published on the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the March 27, 1964, Magnitude 9.2 Great Alaska Earthquake and extended, as detailed investigations, through several...
