Terrain analysis of the lunar equatorial belt
John Francis McCauley
1965, Open-File Report 65-104
The U. S. Geological Survey began, in November 1963, a terrain analysis of the lunar equatorial belt (10°N-10°S, 60° W15°E), on behalf of the National Aeronautics and Space Administration. The purpose of the study is to establish a quantitative classification system in terms of different degrees of relative resolvable roughness,...
Gravity survey in the San Luis Valley area, Colorado
J. Robert Gaca, Daniel E. Karig
1965, Open-File Report 66-46
During the summers of 1963 and 1964, a regional gravity survey covering 6,000 square miles of the San Luis Valley and surrounding areas was made to determine subsurface basement configurations and to guide future crustal studies. The San Luis Valley, a large intermontane basin, is a segment of the Rio...
Quality of surface waters in the lower Columbia River Basin
John F. Santos
1965, Water Supply Paper 1784
This report, made during 1959-60, provides reconnaissance data on the quality of waters in the lower Columbia River basin ; information on present and future water problems in the basin; and data that can be employed both in water-use studies and in planning future industrial, municipal, and agricultural expansion within...
Water resources in the vicinity of municipalities on the western Mesabi Iron Range, northeastern Minnesota
R. D. Cotter, H. L. Young, L. R. Petri, C. H. Prior
1965, Water Supply Paper 1759-B
Additional supplies of water are available near the municipalities on the western Mesabi Iron Range. Potential yields from both ground-water and surface-water sources are good. The most productive aquifers for ground-water supplies are the Biwabik Iron-Formation and the stratified glacial drift. Areas of stratified drift believed to have good water...
Suitability of irrigation water and changes in ground-water quality in the Lompoc subarea of the Santa Ynez River Basin, Santa Barbara County, California
R. E. Evenson
1965, Water Supply Paper 1809-S
Analyses of water samples collected since 1934 from some of the irrigation wells in the Lompoc subarea of the Santa Ynes River valley have shown a gradual deterioration in the chemical quality of the water. Most of the ground water pumped in the subarea has a dissolved-solids contents ranging from about...
