The mineral resources of the Sierra Nevada de Santa Marta, Columbia (Zone I)
Charles McFarland Tschanz, Andres Jimeno V., Jaime B. Cruz
1970, Open-File Report 70-329
The Sierra Nevada de Santa Maria on the north coast of Colombia is an isolated triangular mountain area that reaches altitudes of almost 19,000 feet. The exceedingly complex geology is shown on the 1:200,000 geologic map. Despite five major periods of granitic intrusion, three major periods of metamorphism, and extensive...

1970, Open-File Report 70-307
Digital computer processing of 12 wavelength bands of visible and reflective infrared scanner data has resulted in successful automatic computer mapping of eight terrain units in a Yellowstone National Park test site. Target areas in the scene were selected for training the computer. Statistical parameters of radiance such as mean,...
Geologic studies of Yellowstone National Park imagery using an electronic image enhancement system
Harry Wynn Smedes
1970, Open-File Report 70-306
This report describes the image enhancement system developed by the Philco-Ford Corporation; the kinds of enhancement attained; the results obtained from various kinds of remote-sensing imagery (mainly black and white multiband, color, color infrared, thermal infrared, and side-looking K-band radar) of parts of Yellowstone National Park; and possible additional fields...

The Raft River Basin, Idaho-Utah as of 1966: A reappraisal of the water resources and effects of ground-water development
E.H. Walker, L.C. Dutcher, S.O. Decker, K.L. Dyer
1970, Open-File Report 70-355
The Raft River basin, mostly in south-central Idaho and partly in Utah, is a drainage basin of approximately 1,510 square miles. Much arable land in the basin lacks water for irrigation, and the potentially irrigable acreage far exceeds the amount that could be irrigated with the 140,000 acre-feet estimated annual...

1970, Open-File Report 70-32
An evaluation of the streamflow data available in Oklahoma has been made to provide guidelines for planning future data-collection programs. The basic steps in the evaluation procedure were (1) definition of the long-terms goals of the streamflow-data program in quantitative form, (2) examination and analysis of streamflow data to determine...
